Enhancements continue for the quintessential performance sedan
Since its introduction to the ÚS in 1987, the BMW M5 Sedan has been the essence of the M philosophy: the combination of exhilarating performance, knife-edge handling and superior comfort wrapped in understated bodywork that sends the sharp-eyed observer subtle hints about its stunning capabilities. Without a doubt, the 2010 BMW M5 Sedan continues to exemplify what it means to be an M vehicle.
Starting at $86,325, the price of 2010 BMW M5 Sedan remains unchanged from the previous model year, however it has been enhanced with the addition of BMW s latest 4th generation iDrive controller and screen to compliment the standard on-board Navigation System.
With its 5.0-liter V10 capable of 500 horsepower and choice of 7-speed SMG or 6-speed manual transmission, the M5 offers a potent driving experience unlike any other sedan on the road. In spite of its impressive level of performance, the M5 is also a true luxury sedan. (concept carz) The M5 interior features door panels that include large door pockets and wood trim along the tops of the doors. The front passenger door handle is wrapped in leather and the location of the door handles is ergonomically ideal, with the window buttons located on the door armrests. Pearl-gloss chrome inserts are on the radio and temperature controls.
A heated M multi-function steering wheel and soft-close doors are available as stand-alone options as is an iPod/ÚSB Adapter which enables the M5's audio system to play an MP3 player. It fully integrates the iPod's functionality into the audio controls on the multi-function steering wheel as well as charge the iPod. High Definition (HD) radio with multicasting is also an option. HD radio improves the sound quality and allows access to additional radio programming.
More intuitive operation, expanded functions.
BMW iDrive, 4th generation: new graphics and controls.
New controller concept, high-resolution 8.8-in. control display.
Optimized menu structures, high-resolution graphics, expanded range of functions.
Greater convenience and more intuitive operation via direct-select keys at the controller, plus more Programmable Memory Keys.
In the 6 Series, BMW s iDrive system of controls and displays is offered in combination with the standard Navigation system. In this iteration, iDrive enters its 4th generation building upon this pioneering development, while making it more natural, more intuitive, simpler and more elegant in its functionality and more esthetically pleasing and enjoyable.
When introduced in the 2002 7 Series, BMW initiated a new direction in the control of vehicle features and functions; via a multi-menu color display and a mouse-like controller usable by driver and passenger alike, a potentially crowded landscape of buttons and knobs was supplanted by a computer-logic control path.
An overarching attribute of iDrive was the separation of control (via the console controller) and display (the centrally placed iDrive monitor). This basic arrangement remains; the controller has been further developed and the display has evolved markedly.
Positioned centrally in the instrument panel, the new control display sets higher standards for logical, readily understood menus and attractive graphics. The controller has been refined for comfortable, intuitive selection and activation of functions via standardized turn, push and tilt motions, while being augmented with new direct-selection keys for specific menus, plus more of the Programmable Memory Keys that were included in the previous model year.
Greater functionality, satisfying to use: controller with direct-selection keys.
Benefiting from the newest biomechanics R&D, the state-of-the-art controller operates with tactile precision and clearly structured motions. New control elements, menu schemes and graphic representations in the control display become evident upon first use, yet user appreciation grows over the longer term. A graphic depiction of the controller in the display itself helps orient the user to the next control step; the rotation, pressing and tipping motions generally correspond to those of a computer mouse.
Engine : 5.0 L., 10-cylinder
Power: 500 hp
Torque: 383 ft-lbs
7-speed Semi-Automatic6-speed Manual
Thus interpreted, rotation of the controller takes the user through menu selections; pressing it makes the choice. Tilting the controller to the left or right commands navigation through various menu levels. Via clear graphic organization in the form of stacked layers and onscreen depiction of controller movements, the user enjoys highly intuitive navigation. (posted on conceptcarz.com) All menus are structured according to a consistent scheme, so that one is almost immediately at ease; menus are broad so that the user can view relatively numerous options without switching to another level. Also, functions are arranged so that in longer-term use the most important options are reached more rapidly.
An additional new refinement is four direct-selection keys, placed adjacent to the controller, for the most frequently used menus. These allow quick selection of CD, radio, phone and navigation menus, and are augmented by three further keys of general utility: one takes the user directly to the start menu (MENÚ), one to the most recently active menu (BACK), and the third (OPTION) presents various options within the current area. Thus searches are likely to be shorter, or unnecessary.Familiar and proven, yet now more useful: Programmable Memory Keys.
An iDrive enhancement recently introduced in various BMW models represents a further user convenience: Programmable Memory Keys. When first introduced, there were six of them; now there are eight. Lined up above the audio controls, these allow the user to capture and store favorite or frequently used functions (radio stations, phone numbers, navigation destinations for example) on various keys and recall them instantly. The stored functions can be as specific and detailed as a navigation map in the preferred scale or an audio balance setting. And because the keys are sensitive not just to being pressed but also to being merely touched, one can see the stored function on the control display by lightly touching the key. If it s the right one, the user need only press the key and it s there, ready to use.High-resolution display, preview maps and full-screen images.
With its 8.8-in. high-resolution monitor, the new iDrive displays remarkably attractive images. The system is appropriate to the vehicle, achieved via up-to-date hard- and software. White-on-black menu lists; effective symbols and icons; contemporary graphics; and clear, consistent color-coding are among the elements that enhance not only function but also esthetics.
Menu structures, too, make finding desired functions easier. In the Start Menu, all functional areas served by iDrive are listed. Selecting a given item leads to its menu layer, where the options of that level are also listed. This consistency in navigation assists in orienting the user, as does the stacking of menu layers in the display. Visual assists further contribute to clarity. And if the user gets to a place where he or she didn t mean to be, the Back key usually reverses the error.Úser-friendlier Navigation system, standard.
This overall refinement of functionality means simpler and more enjoyable use of the on-board Navigation system. Full-screen map displays offer outstandingly detailed views of the geography; maps as well as specific symbols can be shown in 3-dimensional form. Selected points of interest along the travel route appear with near-photographic realism.
Mere input of destinations reveals the new system s impressive capabilities. If the destination appears on a list in the system, a preview map appears as the user scrolls the list; this can help distinguish between places with similar or identical names. If a destination (or a phone number) needs to be entered manually, this is done with a new, circular speller that makes the entry go more quickly.Convenient combination of voice entry and controller operation.
Yet, another iDrive innovation is its ability to combine voice and controller entry called Multi-mode Input. The user can go back and forth between the two methods, while actually inputting; indeed, voice recognition can remain active during input via controller and the user can modify an input via voice. Voice recognition BMW calls it Voice Command is activated by its function key on the steering wheel, and de-activated either upon completion of the action or by pressing the key again. Voice Command is simplified by visual display of the available commands, yet its capabilities go further in that numerous synonyms of these commands are also recognized.
This newly enhanced iDrive introduces a very significant step forward in the operation of automotive features and functions. Greater efficiency, improved logic and clear, attractive displays help define and advance the 6 Series unique character. The newest iDrive helps the 2010 BMW M5 create a user experience that is truly unique.M5 technology
Though based on the current 5 Series Sedans, the M5 is packed with engineering, technology, design and luxury that are all its own. Like all BMW automobiles bearing the 'M' logo, it has been developed by BMW M, the BMW subsidiary for high-performance automobiles. The M5 is produced at BMW's Dingolfing Germany, plant, 60 miles northeast of Munich.Performance & efficiency

Once again BMW M blazes new trails in powertrain technology and performance. The last time a new M5 made its debut, it offered BMW M's first V-8 engine. This generation features M's first V-10 engine for a roadgoing vehicle.
Here's some key data about this amazing engine:
0-60 mph in 4.5 seconds
500 hp @ 7750 rpm, 383 lb-ft. of torque at 6100 rpm
Redline 8250 rpm.
This V-10, designated S85 in BMW parlance, is yet another masterpiece of power from BMW M, setting a new milestone for the performance that can be achieved in a roomy 5-passenger sedan, with generous trunk space and all the luxury and safety features one expects from BMW.
Why 10 cylinders? Elmar Schulte, manager of engine development at BMW, has a straightforward explanation. 'We wanted 5 liters. The ideal cylinder displacement is 0.5 liter. To get 5 liters, we needed 10 cylinders.'
In its general layout, the M5 and engine relates to, and was inspired by, the
V-10 Formula 1 engines that BMW developed from 2000-2005. In fact, both engines' major castings are done at the same BMW plant. Although unusual, a V-10 is a satisfactorily balanced configuration, requiring no balance shafts to make it acceptably smooth. Instead, the crankshaft incorporates two large counterweights. Reporting its driving impressions in the December '04 issue, Road & Track magazine commented: 'Run up through the gears out of a slow corner and the engine pulls with a smoothness that easily rivals the previous M5's engine, arguably one of the smoothest V-8s around.'
Únique sound is a further attribute of the V-10. Even when idling, it sounds exotic; according to Motor Trend (December '04): 'The yowling twin-five snarl as you sear toward max revs is an experience that etches itself deep in your memory. No, it's not super-car loud this car always retains the vestiges of sedan refinement, and you could mount a sustained assault on the Autobahn while the rear-seat passengers sleep.'
High-rpm concept. Like previous M engines, the M5's V-10 was developed to exploit high engine speeds to achieve extraordinary performance. Its redline is 8250 rpm; its maximum power of 500 hp is achieved at 7750 rpm and its maximum torque of 383 lb-ft. is realized at 6100 rpm. This strategy, which avoids extreme torque and instead allows the driver to extract super performance by 'revving' the engine, facilitates the use of relatively light, low-mass reciprocating components inside the engine. This helps moderate overall vehicle weight and optimizes the front/rear weight distribution.
Also like other M engines, the M5 V-10 does not employ the Valvetronic system now found in BMW's regular-production I-6, V-8 and V-12 engines. Though Valvetronic eliminates the energy-wasting action of throttles, it is not (yet) suitable for high-rpm engines. Instead, the M5 V-10 uses a typical BMW M valvetrain with 4 valves per cylinder actuated by 'box-type' hydraulic lifters developed for motorsports. These are small, lightweight and extremely rigid, as they must be to survive an 8250-rpm environment. They are also specially shaped for efficient valve operation, with an oblong cross-section (not round like bucket tappets), slightly curved contact surface and guiding tab to ensure a consistent position in their bores.
The valves themselves are also light, with stems of only 5 mm/0.2 in. And, as on the new six-cylinder engines, the camshafts are hollow, further reducing inertia and enhancing engine response. Altogether, the valvetrain's reciprocating mass has been reduced 17.5% from the previous M5's engine; an important facet of the high-rpm concept. So are the light, but ultra-strong pistons and connecting rods.
As in all recent M engines, a special High-Pressure Double VANOS system varies the intake and exhaust valves timing steplessly and quickly. As on the M3 engine, the VANOS system has its own hydraulic pump; this contrasts with BMW s regular-production engines, whose VANOS draws its pressure from the main oil pump. The resulting very high pressure (up to 115 bar/1668 lb./sq in.) enables the valve timing to be varied more quickly than on the regular engines yet another factor in the high-rpm concept.
Four overhead camshafts actuate the valves. Each of the two intake camshafts, positioned inboard, is driven by a simplex chain; from the camshafts chain sprockets, the exhaust camshafts are driven by gears. The system is extremely rigid again, as it must be for this engine s level of rotational speed. Each chain is hydraulically tensioned and needs no periodic adjustment or replacement.
A throttle for each cylinder. Maintaining a BMW M tradition, the V-10 has an individual, electronically controlled throttle for each cylinder.
Breathing an engine s ability to ingest and combust air is naturally a top priority in a super-performance engine. Air is taken in at the vehicle s front, passes through two large intake silencers and two air-mass meters, and then flows into the voluminous plenum (made of a lightweight compound material) atop the engine. From there, air passes through equal-length intake trumpets and the 10 throttles to the individual cylinders. The entire assembly of plenum and trumpets is attached to the throttle housings via a flange (one per bank) that acoustically and thermally decouples the plenum from the engine itself.
Compared to most engines single throttle (or even to the throttle-less Valvetronic system of contemporary BMW engines), these are a costly feature, reserved for the highest-performance engines. Positioned much nearer the cylinders than a single throttle can be, they eliminate a lag time inherent in airflow and foster lightning-fast response to throttle movements. Motor Trend characterized this engine s throttle response as blazingly urgent.
Actuation of the throttles is electrically driven and electronically controlled. Each cylinder bank s five throttles are actuated from a single shaft. Via the accelerator pedal, the driver gives the commands. In turn, these commands are processed by the engine control module and received by a DC servo motor (also one per cylinder bank). The motor drives the throttle shaft through a tiny gearbox.
Via the M Drive system (described later), the engine s maximum power and the throttles response to the accelerator pedal can be set to different levels; see M Drive.
Últra-high compression ratio. At 12.0:1, the V-10 again notches up BMW s highest current compression ratio. The higher the compression ratio, the more power can be extracted from a given engine size, another factor in the V-10 s performance.
Ionic-current knock control technology. In a world first for such a high-revving engine, and a first for BMW, BMW M s engineers have applied an exotic technology to the knock control system that is crucial with such a high compression ratio. Instead of piezoelectric knock sensors positioned in the cylinder block to detect detonation via sound-pressure level, the spark plugs themselves do the knock-sensing and do it incredibly quickly and directly.
The air-fuel mixture in an engine s cylinders has a certain electrical conductivity, which varies especially as knock, or detonation, occurs in a cylinder. Built into the engine s electronics is circuitry that applies a small voltage across the sparkplug s electrodes just after it fires; the resulting ionic current is a function of the combustion process taking place. If knock (detonation) is incipient, the ionic current will so indicate; a signal goes to the engine s electronic control system and ignition timing is retarded appropriately. In all BMW knock-control strategies, each cylinder s combustion process is measured individually; if only one cylinder is tending to knock, only that cylinder will have its ignition timing retarded.
The advantages of ionic-current technology over conventional block-mounted knock sensors are:
Ignition adjustment occurs more quickly. The whole process onset of knock, measurement of ionic current, adjustment of timing takes place in just 0.8 milliseconds at 8000 rpm, rapid enough to adjust the timing before that sparkplug s next firing.
Because of its extreme sensitivity and speed, this technology allows the engine to edge closer to its full potential in the upper reaches of power and rpm.
Helps control fuel consumption and exhaust emissions.
Ionic-current technology does not require a different type of sparkplug, nor is the sparkplug s durability affected by its extra duty. The current-measuring voltage is only about 100 volts, vs. more than 25,000 V applied to fire the sparkplug.
Weight-efficient construction. The M5 engine is made of aluminum, with bedplate construction for the lower portion of the cylinder block. This construction is inherently ultra-rigid; for the strength to withstand the massive internal forces of this engine, however, the main-bearing inserts are of cast iron. Sharing a major feature of most current BMW engines N52 6-cylinder as well as all V-8s and V-12 the cylinders are silicon-impregnated, with soft honing removing just enough of the aluminum to leave the silicon crystals as ultra-hard cylinder surfaces.
The entire engine weighs just 240 kg/529 lb. almost exactly the same as its V-8 predecessor, yet the V-10 delivers fully 106 hp more output!
G-sensitive lubrication system. Given the 45 cant of the cylinder banks and the M5 s cornering ability, special attention has been directed to ensuring natural return of oil to the main sump. There are two sumps, the main and larger one behind the front frame crossmember and a smaller one forward of the member; a baffle separates the two from each other in this semi-dry-sump system.
First, the mechanically driven main oil pump is a variable-volume type, an innovation also found on the N52 6-cylinder engine. By varying the output of its pump element according to engine oil pressure, the engineers have achieved a pump that always delivers sufficient pressure to lubricate this demanding engine, yet never pumps more oil than is necessary. Thus it contributes to the high power output, by requiring less power from the engine and doesn t require a bypass to divert excess flow; this helps avoid excess oil temperatures and oil foaming.
There is also a recirculating pump that picks up oil from the small front oil sump and transfers it back to the main sump. Additionally, there is an electrically driven scavenging pump for each cylinder bank. In straight-ahead driving, these pumps pick up oil from the rear of the engine and return it to the sump. In hard cornering (0.6g or greater), the Dynamic Stability Control system s lateral-g sensor switches magnetic valves to different pickup points in the cylinder heads and the oil pan that are closest to the outside of the curve. This system remains active even if the driver switches off DSC.
The oil level and temperature are monitored by a thermal sensor; a warning is displayed if the level falls low, and an oil-temperature gauge is included in the tachometer face. Oil is cooled by a coolant-oil heat exchanger.
Low-back-pressure, tuned exhaust system. Exiting the engine through stainless-steel exhaust headers that Germany s auto motor und sport magazine (November 10, 04) called an artwork in stainless steel, exhaust gas from each cylinder travels an ideal length of 560 mm/22 in. before reaching the engine-close first catalytic converter on each side. A high-pressure forming technique is used to shape the headers, enabling them to achieve the necessary strength and desirable light weight with only 0.8- mm/0.03-in. wall thickness. Two additional catalytic converters, one per side, are located farther downstream in the system.
Further advanced engine electronics. Once again BMW M has developed a new, ultra-powerful electronic control system; called MS S65, this scheme incorporates much of the experience gained from the V-10 racing engine. All the engine s electronic functions throttles, ignition, fuel injection, lubrication, dialog with the Sequential Manual Gearbox, and more are overseen by a central electronic module employing three 32-bit microprocessors capable of 200 million operations per second.
This system also incorporates the M Drive functions, including the three power levels and throttle calibrations described under M Drive.
Variable tachometer warning zone. Pioneered on the previous M5 engine and now found on the 5, 6 and 7 Series and M3s tachometers as well, this feature reminds drivers that a cold engine should be treated with care. Displaying a yellow caution segment and a red limit segment, this zone moves from a minimum point with a cold engine to the full 8250 rpm redline as the engine oil warms up.
7-speed Sequential Manual Gearbox:
advanced technology for optimum performance
This unique SMG transmission employs Formula 1 racing technology to help drivers extract the M5 s full performance potential. The SMG system does everything a manual transmission can do, plus several things a manual can t:
Offers 7 forward gears, which would be awkward for a manual shift lever to manage.
In high-performance driving, can shift much faster than even an expert driver.
Can provide automated shifting when desired.
Offers a wide variety of shift programs in Automated and Sequential modes.
Engages and disengages the twin-disc clutch, precisely coordinating its action with shifts. There is no clutch pedal.
This is the first SMG designed and developed right from the start as an SMG. Two BMW M generations and the simpler system offered in regular-production BMWs were created by adding SMG controls to a conventional manual transmission. (posted on conceptcarz.com)
This has sweeping implications for how the concept operates and what it can do:
The gears are positioned so that the gearsets with the greatest loads (1st, 2nd and 3rd) are closest to the load-carrying bearings. This promotes durability in a transmission that must transmit immense power and is shifted fast and hard.
To be shifted by a conventional shift lever, this gearset placement would result in an extremely awkward shift pattern. But this was not a problem, because all shifting would be executed the SMG way.
Even if the shift pattern were manageable, 7 speeds would be difficult for a driver to manage; a 6-speed is the practical limit for a purely manual transmission. (posted on conceptcarz.com)
And yet with a high-revving, high-performance engine, 7 speeds are ideal and desirable, tangibly helping the driver extract such an engine s full potential.
The entire internal mechanism gears, shafts, bearings, shift rods could be laid out optimally for SMG s electrohydraulically powered shifting; it is in no way compromised to allow conventional manual shifting.
The mechanism allows simultaneous actuation of two shift rods at once, which helps the unit achieve lightning-quick shifts. Additionally, the gear synchronizers utilize carbon-fiber cones, which also contribute to the ability to shift so fast.
DRIVELOGIC shift programs, 11 of them. In this respect, the new transmission parallels BMW M s 6-speed SMG, offered on M3s since 2002. There are two basic shift modes: Sequential (S), in which most shifting is initiated by the driver; and Automated (D, for Drive), in which operation is similar but by no means identical to that of an automatic transmission. (posted on conceptcarz.com)
Within these two modes, there are as before a total of 11 shift programs:
Sequential 6 programs, S1-S6 from softest and slowest to hardest and quickest shifts; i.e. from most leisurely to sportiest. The driver initiates shifts with either the console shift lever (tip forward for downshifts, rearward for upshifts) or paddles on the steering wheel (left paddle for downshifts, right for upshifts).
Automated 5 programs, D1-D5 similarly from mildest to sportiest, with the distinction that as the program gets sportier, the engine speeds at which shifts occur also move upward. Even in this D mode, if the driver manually initiates a shift, the unit switches to S and remains there until D is again selected by the driver.
In S6, the sportiest program of all, minimum shift time is reduced 20% from the existing SMG already very fast. In everyday driving, shifts are now smoother.
In the SMG transmission, gears are shifted electrohydraulically; shifting is controlled by a 16-bit microprocessor that can make up to 12 million calculations per second.
Special functions and safeguards. The 7-speed SMG incorporates a number of special functions and safeguards:
Automatic downshift to 1st gear for starting off from rest, whether in D or S mode. If the mode selector is in D, upshifts will then occur automatically; or the driver can initiate the upshifts.
Over-rev protection. If the driver calls for a downshift (S mode) that would over-rev the engine, the downshift command is ignored.
Slip Control. If a downshift occurs on a slippery road, SMG disengages the clutch for a split second to prevent sudden wheel slip that could de-stabilize the vehicle.
Start-off Assistant. When stopped facing uphill, the driver simply holds the brake pedal until ready to start off. Úpon release of the brakes, the M5 is ready (for 1 second) to start off without rolling back.
Hill Detection. Depending on road gradient, down- or uphill, the D shift points are modified for optimum gear selection. In S, shift times are shortened so that the engine is always on point for best acceleration uphill, or engine braking downhill.
Smooth downshifting. In D or S mode, DRIVELOGIC coordinates clutch disengagement, shifting, engine speed and clutch engagement to accomplish smooth downshifts just as a skilled driver would.
2nd-gear start in D1 program: Starting up from rest, the transmission is in 2nd rather than 1st; the clutch engages slowly. Although the traction-control function is also there to prevent it, this reduces the chance of even transitory wheelspin.
6-speed manual transmission
This no-cost optional transmission has been developed for and is offered exclusively in the North American market. It is the perfect choice for those driving enthusiasts who want to enjoy the 500-horsepower V-10 engine with the level of driver-car interaction that only a manual gearbox can provide. Of course, as with any BMW, the pedals are arranged to provide smooth and quick heel-and-toe downshifting.
The M5 equipped with the manual transmission features the same M Dynamic Mode (MDM) stability system as the Sequential Manual Gearbox (SMG) car. M Dynamic Mode enables enthusiastic track driving with greater longitudinal and lateral acceleration on dry surfaces; however, with limited vehicle stability, corrections by the driver may be required. With the M Dynamic Mode activated, stabilizing interventions occur at a reduced level. Both DSC and MDM can be fully deactivated starting with September 2007 production.
Changes from the regular-production 550i affect the suspension system and its connections to the body structure; a special M version of Electronic Damping Control; the M Variable Differential Lock; Servotronic steering with two levels of power assist; amply dimensioned, cross-drilled brakes; and wheels and tires that give the M5 an awesome footprint.
Start with suspension hardware, already an advanced all-aluminum system on the 5 Series. (The vehicle s frontal structure is also aluminum, helping contain overall weight and contributing to near-perfect front/rear weight distribution.)
At the front, modifications include the subframe and thrust plate (both still aluminum), fine-tuning of geometry, more rigid bushings and a 0.9-in. wider track. At the rear, the changes are more extensive:
The subframe is modified.
Suspension links are essentially the same as on the BMW Z8 Roadster.
Bushings are stiffer.
Axle halfshafts are hollow for reduced weight with greater strength.
Geometry is tailored to the greater torque that will flow through the whole system. Here the track is actually narrower (by 0.6 in.) than that of a 5 Series with standard wheels, because the 285/35 rear wheels center plane must be farther inboard for their massive tires to clear the bodywork. But the M5 s actual footprint is wider.
And at all four wheels, specially calibrated springs and shock absorbers the latter made variable by Electronic Damping Control complete a sporting chassis that only BMW M could create.
M Electronic Damping Control
EDC steplessly controls the shock absorbers to any level between softest and firmest, precisely adapting to road conditions and the driver s demands at any given moment:
Ride firmness is always optimum for current road conditions, vehicle speed and vehicle loading (passengers and luggage).
On smooth roads, the shock absorbers are kept at the softest appropriate setting (considering the character of the vehicle) for riding comfort.
When the vehicle is rounding a sharp corner or curve, the shock absorbers are automatically and instantly adjusted to a firmer, just-right level.
On any irregular road surface, the shocks automatically and instantly adjust to the optimum level of firmness to control ride motions, preserve riding comfort and maintain adhesion to the road.
Basic system properties are calibrated to M car character.
On the M5, there are three modes. Selected via the EDC console button or M Drive menu, they are:
Comfort, shifting the balance toward riding comfort. Appropriate for gentle, speed-controlled driving on relatively smooth and straight roads.
Normal, likely to be chosen most of the time; a judicious blend of M-style handling precision and riding comfort.
Sport, putting top priority on the M5 s tremendous road capabilities at some sacrifice of riding comfort.
Within each mode, EDC continuously adjusts shock-absorber firmness to actual conditions. Writing in Automobile Magazine s November 04 issue, Georg Kacher concluded that The new M5 is intuitive and involves the driver every step of the way. It is as stable as its rivals in a straight line, but its steering is lively and soulful. It is as fast through corners, but its handling is sublime and unambiguous. It is as strong on the brakes and as energetic on the throttle, but it never forgets to generate feel and feedback.
M Variable Differential Lock:
putting power to the road, the BMW M way
Mechanical limited-slip differentials belong to BMW M s tradition of ultimate road handling. Together with the German division of GKN Viscodrive, BMW M engineers developed a more capable mechanical limited-slip differential; called the M Variable Differential Lock, the concept appeared first on the 2001 M3, and is now also utilized by the M5.
Únder dry to not-quite-dry road conditions, the traditional 25% limited-slip has some ability to improve traction; but under split-traction conditions (one wheel on slippery, the other on firmer ground) it cannot transmit more torque than the slippery side permits. On all current BMW models, electronic traction control (a function of Dynamic Stability Control) addresses this issue, though not optimally for sporty driving in the M Car sense. (Thus there s a switch to reduce or altogether eliminate DSC action when the driver so desires.)
The M Variable Differential Lock specifically addresses low- and split-traction situations in a way that reinforces sporty handling, imparting a slippery-road ability other high-performance, rear-wheel-drive sports cars generally do not have. The main distinction between a traditional limited-slip diff and the M Variable Differential Lock is that where the former senses torque, the latter senses wheel speed.
Anytime a speed (rpm) difference develops between the two rear (driven) wheels, a shear pump, driven by this difference, develops pressure in the unit s silicon viscous fluid. This pressure is applied to a multi-disc clutch that transfers driving torque to the wheel with better road grip (this priority is called select high ). The greater the speed difference between the two wheels, the more aggressively the clutch engages. As this wheel-speed difference diminishes, the clutch begins to ease off.
This mechanism accomplishes finely calibrated action by entirely natural means. There is no external pump, no external source of lubrication or operating fluid. The very motion to be controlled differences in speed between one wheel and the other generates its locking action.
Servotronic steering with two effort levels
The BMW M5 s rack-and-pinion steering system has Servotronic vehicle-speed-sensitive power assist.
Also, the steering ratio the number of degrees the steering wheel must be turned to steer the front wheels by 1 degree is variable; the ratio gradually becomes quicker (greater steering angle relative to steering-wheel turns) as the steering wheel is turned away from its center position. This is not BMW s Active Steering, which varies the steering ratio more widely and does so in response to vehicle speed; instead, BMW M chose to tailor the 5 Series standard steering system to the attributes of this ultimate sports sedan.

But variable ratio and Servotronic assist aren t all that s special. The M5 offers the driver a choice of two levels of assist: Comfort, with typical BMW assist, and Sport, with less assist for a sportier feel. Within these two settings, Servotronic varies the assist according to vehicle speed.
Immensely powerful, fade-resistant compound, cross-drilled brakes
To match its colossal performance, the M5 features immensely dimensioned ventilated disc brakes. At the front, they are 374 mm/14.7 in. in diameter and 36 mm/1.42 in. thick, compared with the 550i s already generous 348 x 30 mm. At the rear, they re 370 mm/14.6 in. in diameter and 24 mm/0.94 in. thick (550i: 345 x 24). But the M5 goes further, with compound brakes.
This most elaborate of BMW brake concepts shares 2-piece rotors with the 550i and 6 Series: an aluminum hat inner portion to reduce unsprung weight, and a cast-iron outer portion as the actual friction surface. But whereas on those models the hat and outer portion are riveted together, here the hat and outer portion are connected by steel pins on which the aluminum and cast-iron portions, because of their differing expansion rates, can move relative to each other.
The M5 aluminum/cast-iron rotors cut unsprung weight, and reduce rotor deformation under hard-braking, high-heat conditions by about 20%. This construction is more elaborate and costlier. It saves an equal weight proportion, and totally eliminates deformation. This means virtually no tendency of the brakes to vibrate when red-hot, and virtually no likelihood of the rotors cracking even under the extreme temperatures that might be encountered in driving on a racetrack.
Additionally, the M5 brake rotors are cross-drilled to enhance heat dissipation beyond that provided by the rotors internal ventilation; this further enhances fade resistance. It also reduces weight unsprung weight by a full 1.5 kg/3.3 lb. per rotor. The front calipers have dual pistons, another M5 upgrade; front and rear calipers highly visible through the wheels are finished in glossy black.
Thus the M5 incorporates BMW s most capable braking system. It is one of the many reasons why the M5 is a truly track-ready car.
Wheels and tires: ultimate grip and style
In its wheel-tire equipment, the M5 takes the 5 Series platform to its ultimate level of performance and style. The wheels, in a relatively open, discreetly aggressive M Radial Spoke design, are sized 19 x 8.5 front/19 x 9.5 rear and carry 255/40ZR-19 front/ 285/35ZR-19 rear, high-performance tires specially developed for the M5.
These are not run-flat tires; there are no run-flats yet that meet BMW M parameters of speed rating and weight. The M5 exhaust system, with its four main mufflers clustered at the rear of the vehicle, does not provide space for a spare tire, so the M5 is equipped with the M Mobility System.
If a tire is punctured a rare event in any case the M Mobility System provides for temporary repair and inflation of the damaged tire. Should a tire ever be completely destroyed, BMW Roadside Assistance is available for the life of the vehicle.
Specially calibrated, variable Dynamic Stability Control
DSC is standard on all BMW models; on the M5, this electronic traction and stability system complements the M Variable Differential Lock.
DSC optimizes traction by electronic means. In cooperation with supplier Continental Teves, BMW M engineers developed specific DSC logic that, together with the fast-responding engine, performance-oriented gearing and differential lock, achieves traction enhancement in an M-compatible way in other words, without undue interference with M5 performance and the differential lock s ability to get M power to the road.
The M5 s DSC also includes some new functions recently added to other Series:
Brake Standby. When the driver lifts off the throttle pedal abruptly, DSC senses that sharp braking may be about to occur and applies just enough pressure to snug up the pads against the rotors. Thus by the time the driver s foot reaches the brake pedal, the short lag from bringing the pad to the rotor is eliminated; this can reduce the stopping or deceleration distance.
Brake Drying. Acting on input from the windshield wipers rain sensor, the pads are periodically brought up to the rotors just enough to eliminate any film of water between pads and rotors, but not enough to cause any brake application.
The M5 DSC takes on a unique dimension by offering an M Dynamic Mode. Activated by the DSC console button, this mode allows more oversteer and wheelspin, useful to an expert driver on a racetrack. It is not recommended for use on public roads.
M technology at the driver s disposal
Via the M Drive system, the driver has fully 279 combinations of control settings to choose from and an M Drive button on the steering wheel that allows 1-touch selection of the driver s preferred combination. Here s how it all works:
Power and throttle response. Three settings: P400, the default mode, allows a maximum of 400 hp and gives normal throttle response. P500, the normal performance setting, allows full maximum output of 500 hp, with quicker throttle response. Both these settings may be selected conveniently via the Power button on the console, next to the shift lever. The third setting, P500 Sport, also allows full engine power, but provides even quicker throttle response. It is selectable only in the M Drive menu on iDrive.
Transmission. SMG provides 5 automated programs in Drive, D1-D5; 6 programs in Sequential, S1-S6.
Electronic Damping Control. Comfort, Normal and Sport settings. Steering assist is linked to these: Its Comfort mode (more assist) goes only with EDC s Comfort setting. The steering s Sport mode (less assist) goes with EDC s Normal and Sport.
Dynamic Stability Control. Three settings: Normal, M Dynamic Mode and de-activated (though ABS always remains active).
Selecting modes in M Drive. Within the M Drive menu, the driver can select every one of these settings and link them to the M Drive button on the steering wheel. Then, regardless of which individual settings have been selected previously, all these choices are instantly set to what the driver has programmed in M Drive. Conversely, the previous settings will be restored when the M Drive button is pressed again.
Power settings P400 and P500 can be summoned by pressing the appropriate button on the console. So can the EDC and DSC modes; likewise the SMG program, which can be set via the shift lever and the mode selector behind it.
Additional M Drive settings. Two optional features the M Head-up Display and the M Multi-function seats Active Seat Backrests can also have their settings programmed onto the M Drive button via the M Drive menu.
Abundant luxury accompanies definitive performance
Imagine the sportiest and most luxurious 5 Series interior. Then imagine it even sportier, more luxurious, and fitted out to enhance enjoyment of BMW M performance. That would be the M5 interior upholstered in Merino Leather, BMW s finest grade; trimmed in brushed aluminum or a choice of two elegant woods; offering a unique selection of upholstery colors; providing special instrumentation and displays; and offering options such as the M Head-up Display and M Multi-function seats with Active Backrest Width.
Special M instrumentation
Both main instruments have unique fulltime-illuminated white scales and red pointers. The speedometer scale reads to 200 mph, the tachometer to 9000 rpm. A variable tachometer warning segment in yellow, with red normally beginning at 8250 rpm, is included. Via a rotating disc behind the instrument face, this segment can move downward to as low as 4500 rpm with a cold engine, then gradually rise to the full 8250 rpm as the engine warms. On the speedometer, a similar disc carries a pointer indicating the set speed for the cruise control.
With such a high-performance engine, oil temperature is a critical factor and the one to which the variable rpm limit is calibrated. Accordingly, an oil-temperature gauge is set into the lower portion of the tachometer. As a further distinction of M5 instrumentation, via the On-board Computer the driver can select oil temperature (instead of average speed) to be shown in the instrument-cluster display.
M sport steering wheel
The M5 s power tilt/telescopically adjustable steering wheel is sized, proportioned and designed to be as sporty as it gets. Its distinctions include:
Smaller diameter: 381 mm/15.0 in. vs. 5 Series 385 mm/15.2 in.
Thicker rim, padded leather with M-color stitching
Thumb contours at 10 and 2 o clock
SMG paddles above lateral spoke: right for upshift, left for downshift
Round center and unique spoke shape
M Drive button replaces one of the 5 Series programmable buttons.
A heated version of the M steering wheel is a stand-alone option.
Merino leather, Extended or Full treatments
BMW s finest leather grade, Merino, is available in three versions and with unique M colors making up most of the palette.
Standard is an Extended treatment of Merino, appearing not only on the seats and panels but also the door armrests, center-dash area (surrounding the climate and the audio controls), center console and armrest, and handbrake boot. In the optional Full treatment, leather is also applied to the dash. Perforated Merino is available in the Full treatment; it is mandatory with the optional Active Seat Ventilation.
Special interior trim
The standard interior trim appearing across the dash, on the door pulls and on the center console is a boldly brushed aluminum. Optional at no extra cost are two elegant woods: Olive Ash, a medium-tone wood with burl grain; and Madeira Walnut, reddish brown with more linear grain.
M sport seats
BMW M sport seats embody comprehensive design and features for supporting the driver in enthusiastic driving.
The standard M front sport seats include adjustable backrest width, which enhances their adaptability to various human statures. Along with the steering wheel and exterior mirrors, each driver s preferred adjustments are stored in Vehicle & Key Memory and are reset to those adjustments when that driver unlocks the vehicle with his or her remote.
A new dimension in sound
The Premium Sound audio system with enhanced bass, created by sound specialists at BMW M, incorporates high-quality hi-fi components designed especially for use in automobiles and a newly developed BMW-exclusive signal processing technology. The system is available as a stand-alone option on the 2010 M5.
Úp to 16 high-performance loudspeakers featuring Neodym magnetic drive and exceptionally stiff Hexacone diaphragms, a digital nine-channel amplifier with a maximum output of 825 watts and precision crossovers guarantee unparalleled sound quality. The system's DIRAC live signal processing technology is unique in the automobile industry. It corrects the impulse response of each loudspeaker, thus facilitating linear and accurate sound reproduction inside the car. The resulting true impulse response during sound reproduction enables both the driver and all passengers in a BMW M5 to enjoy an extraordinarily multi-faceted and vivid sound experience.
The system is compatible with all audio sources featured by the BMW range of optional equipment - radio tuner, CD, and external playback devices such as the Apple iPod. The system is operated using the iDrive controller. As is the case with all in-car entertainment systems, basic functions are controlled via the audio control elements situated on the center console.
Loudspeakers featuring Neodym magnetic drive and Hexacone diaphragm
Lightweight, powerful and precise - these basic characteristics contribute to the outstanding quality of the loudspeakers. They convert electric impulses into sound waves by means of the Neodym magnetic drive. Neodym magnetic drives standout in the field of high-end hi-fi components through particularly high-performance and low weight. In spite of the large number of loudspeakers employed, the total weight of the BMW system is more or less the same as conventional sound systems.
In addition, the design of the loudspeaker diaphragms meets the most stringent quality standards required in the hi-fi sector. The lightweight and ultra-stiff Hexacone diaphragms are particularly suitable for both powerful and demanding sound reproduction. Not only do they have generous power reserves but they also offer a high degree of effectiveness. The maximal acoustic pressure is 112 dBA, the frequency range being 18 to 24 kHz. Both subwoofers are located in the vehicle floor and the mid-range speakers and tweeters are installed in the doors or in the rear panels, in the instrument panel, in the mirror triangles and in the rear shelf respectively.
The mid-range speakers and tweeters differ visually from conventional loudspeakers. They are recognizable by the silver loudspeaker covers and by a grille, which - to match the hexagonal structure of the diaphragm - has a honeycomb design.
Other features standard in M5
In addition to those already described, the list of further features that are standard in the M5 but optional in some or all 5 Series models is extensive. It includes:
Xenon Adaptive headlights with auto-leveling
Headlight cleaning system
Park Distance Control (ultrasonic parking assist)
Real Time Traffic Information
Auto-dimming interior and exterior mirrors
Ambient Light Package, plus M5-specific entry lights on the doors
BMW Úniversal Transceiver (3-function remote control of garage doors, etc.)
Heated front seats.
Safety and security features:
comprehensive engineering and equipment
In terms of safety and security, the M5 along with the 5 Series is a state-of-the-art vehicle from a state-of-the-art vehicle maker. Key features include:
Dual front-impact Supplementary Restraint System (SRS) with dual-threshold deployment of 2-stage Smart Airbags that are optimized for shape and deployment characteristics.
Advanced seat-occupant detection on front passenger s seat.
Front safety belts with automatic tensioners and force limiters standard.
LATCH attachments for child restraint seats at outboard rear seating positions.
Interlocking door anchoring system for side impacts.
Front-seat side-impact airbags standard.
Rear-seat side-impact airbags optional.
Rear safety belts with automatic tensioners included with the optional rear-seat side-impact airbags.
Head Protection System front-to-rear head protection via a tubular airbag that deploys from ceiling and is suspended on a sail.
Active front head restraints included with the optional M Multi-function front seats. Responding to impact sensors at the rear of the vehicle, the head restraints pivot forward into close proximity with the occupants heads. Thus occupants are able, if they prefer, to adjust the restraints away from direct contact with their heads, yet gain optimum protection against whiplash or more serious head/neck injuries.
Energy-absorbing padding of body-pillar and roof areas at the A-, B- and C-pillars as well as along the roof above the doors.
Fuel-tank design and location. The fuel tank is designed to remain sealed in severe impacts; its location was chosen for optimum protection from impacts.
Intelligent Safety and Information System (ISIS) employing 14 sensors to achieve a precise tailoring of safety devices deployment to actual accident circumstances.
Battery Safety Terminal in case of a severe accident impact, breaks the high-current connection between the battery and starter cable. This helps prevent a possible short circuit in the electrical system.
Tire Pressure Monitor alerts the driver to loss of tire pressure.
Automatic fuel-pump shutoff upon severe accident impact. The doors are automatically unlocked; interior lighting and 4-way hazard flashers are switched on. Thus even after an accident, BMW s safety strategy is still at work.
Coded Driveaway Protection The multi-function remote is equipped with a tiny transponder which stores an electronic code transmitted by an antenna at the ignition slot. Each time the remote is removed, this code is changed; the next time, the engine can be started only if the remote matches the new code.
Central locking system with double-lock feature. When the vehicle is locked from the outside, the double-lock feature prevents individual door-lock buttons from being pulled up; thus even if a thief has broken into the car, it isn t possible to open the doors.
Alarm system with interior motion detector standard.
BMW Assist BMW s comprehensive system of customer services and in-car telematics is standard. Includes a 4-year subscription to BMW Assist services.
Options: almost everything is standard
Because the M5 s standard equipment is so extensive, its options list is relatively short. Yet certain features are optional, most of them unique to the M5.
M Multi-function seats. Surely the ultimate in sport seats; In addition to the already extensive adjustments and features of the M5 s standard M sport seats, these add:
Active Backrest Width. Responding to cornering forces, the lower backrest side bolsters tighten at the outboard side in a curve and thus provide extra lateral support to their occupants. That is, in a hard right corner, the driver s and passenger s left lower backrest bolsters move inward; in a hard left corner, the right bolsters tighten. Moreover, there are three programs for this function: Comfort, Normal and Sport in order of firmness, programmable within the M Drive menu.
Adjustable upper-backrest width. Separately from the lower bolsters that incorporate Active Backrest Width, the upper side bolsters are power-adjustable to vary backrest width and support according to their occupants preferences. This adjustment is not affected by the Active function.
Active head restraints described earlier.
Active Seat Ventilation. Multiple fans inside each front seat gently blow air upward through an internal web and perforated leather to provide pleasant ventilation and help keep occupants clothes free of perspiration. Requires Full Perforated Leather and M Multi-function Comfort seats.
Full Leather upholstery and wood interior trim.
Comfort Access. Eliminates the need to activate a remote to unlock or lock the vehicle, or to insert it into the dash slot before starting the engine:
Vehicle access Úser enters vehicle merely by pulling a door handle, or opens the trunk by pressing the trunk release. Presence of the remote (say, as in the user s pocket or purse) has already confirmed that the user is authorized.
Starting Úser authorization is confirmed by the presence of the remote inside the vehicle; the driver starts the engine by merely pressing the Start/Stop button.
Engine switch-off and vehicle locking Driver turns off engine via Start/Stop switch, and presses a door handle to lock the vehicle after exiting.
If the user has left the remote in the interior, the vehicle will not lock. If the remote has been left in the trunk and the trunklid is closed, it will open again as a reminder to retrieve the remote.
Soft-close doors. The user closes the door gently; an electric mechanism draws it fully in. Heated M steering wheel.
M Head-up Display. A virtual image in color is projected from the top of the instrument panel onto a 6 x 3-in. field in the windshield; the driver can observe the information with essentially no diversion from the road ahead. Via the iDrive control display, the driver decides which information is to be displayed here and the brightness of the display.
The M5 s Head-up Display is a special M version, in which either the standard selection of information or a special M set can be displayed:
For the standard set, the user selects any or all of Navigation instructions, cruise-control set speed and current vehicle speed.
The M set includes
Dynamic engine-speed band in green, yellow and red
Úpshift indicator (engine-speed band flashes as the rpm limit is reached)
The gear currently engaged
As with the standard 5 Series Head-up Display, the vehicle speed.
Sirius Satellite Radio. Provides 60 original channels of commercial-free music of virtually every genre; over 40 sports, news and entertainment channels; and other features. The option includes a 1-year subscription to the Sirius service.
• High Definition radio. Described earlier.
• iPod/ÚSB Adapter. Described earlier.
• Enhanced Audio System. Described earlier.
Split folding rear seats and ski bag. The seats are split 60% left/40% right. The pass-through for the ski bag is in the center, as part of the 60% side; as with the standard rear seat, there are three head restraints.
Heated rear seats. Like the heated front seats that are standard, they offer 3-stage/2-zone heating of the outboard seating positions.
Power rear sunshade and manual rear door-window sunshades. The rear-window shade is controlled from a console switch. The door-window shades are manual and easily positioned by rear-seat passengers.
Rear-seat side-impact airbags and rear safety-belt tensioners. The airbags are offered as optional equipment so that customers can decide on the basis of their own priorities whether or not to have them.
High Beam Assistant. This conveninence option automatically turns the high beams on and off depending on the road conditions to offer the most amount of road illumination to the driver without distracting oncoming traffic. This new function can be switched off if the driver so desires.
Rear-spoiler delete. At no extra cost, the standard M rear spoiler can be deleted.Included with every new M5:the M5 Driving Experience
