2007 Porsche Cayman

Following the successful market launch of the Cayman S in autumn 2005, Dr. Ing. h.c. F. Porsche AG, Stuttgart, is introducing the Cayman, a new version of the mid-engine sports coupé. Based on the Boxster series, the two-seater is powered by a six-cylinder boxer engine with an engine-capacity of 2.7 liters and developing an output of 245 bhp (180 kW). With its high and sustained propulsive power in the lower and medium speed ranges, the engine puts in an impressive performance. It has a top speed of 258 kilometers per hour. This sports car with manual transmission accelerates from 0 to 100 km/h in 6.1 seconds. The Cayman is convincing proof of the fact that outstanding performance statistics do not necessarily mean high fuel consumption. According to European standards, it consumes on average only 9.3 liters per 100 kilometers.

Thanks to the Porsche VarioCam Plus system the Cayman affords a torque of 273 Newton meters available between 4,600 and 6,000 revs. Power is transmitted via a five-speed manual transmission with short, precise shifting travel. A six-speed manual transmission in conjunction with the Porsche Active Suspension Management (PASM) system is also available on request. As a third variant, Porsche offers its customers the well-known Tiptronic S five-speed automatic transmission, which has rocker switches in the steering-wheel spokes for sporty gear shifting.

The Cayman coasts along on 17-inch light-alloy wheels boasting a unique design with five double spokes. 205/55 tires are fitted as standard onto 6.5-inch wide wheel rims at the front; the combination at the rear is 235/50 tires on 8-inch rims. With the Porsche Stability Management (PSM) system fitted as standard, the chassis makes an impressive impact in terms of driving dynamics and active safety.
The Porsche Active Suspension Management (PASM) system is available as an optional extra. The system is capable of lowering the body by ten millimeters, and automatically adapts the shock-absorber system to each particular driving situation. The driver can choose between the 'normal' and 'sport' programs by pressing a button on the center console.

Other special features of the Cayman are black brake calipers, black front-spoiler lips, a titanium-colored logo at the rear and also a trapezoidal tailpipe. The impressive interior boasts a comprehensive range of standard features including an air-conditioning system, a radio/CD player, seat covers in luxurious Alcantara leather, black-faced instrument dials and door entry trims with the Cayman logo. Because of the mid-engine concept, it boasts two trunk compartments with a combined volume of 410 liters, just like its big brother, the Cayman S. Along with many other storage features, this design highlights the sports coupé's supreme practicality.

In additional to two full-size airbags to guarantee the necessary level of safety protection in the event of head-on collisions, the ingenious Porsche Side Impact Protection System (POSIP), which features a chest and head airbag on each side of the vehicle, also provides excellent protection in side-on collisions.

The basic price in euros for the Cayman is 40,900 euros. In Germany, the vehicle costs 47,647 euros including sales tax and country-specific requirements. The Cayman will be on sale in the ÚSA for 49,400 dollars (not including tax). The market launch in Europe and the ÚSA will take place on July 29, 2006.

Idea

The eyes see things in an instant that took decades to evolve. The new Cayman and Cayman S are the embodiment of beliefs long held in esteem by the engineers of Porsche—ideas first developed in mid-engine racing machines such as the 550 Coupe from 1953 and the 904 Carrera GTS from 1964.
From its sweeping front shoulders to its roofline arc and sloping rear hatch, every line of the Cayman leverages the accomplishments of its predecessors—sports cars victorious on racetracks from Le Mans to Sebring and Laguna Seca. Just as with these racing forebears, the Cayman and Cayman S find inspiration in dynamic engineering.





As your eyes travel from the fenders to a narrowed midsection, a host of unmistakable shapes come into view: the unbroken curve of the arcing roofline. The precise cut of the door. And the dramatic upward surge of the lower window edge to the rear of the door. Like the wind, your gaze naturally flows to the side intake that feeds air into the strategically placed engine bay. Each of the twin intakes consists of three vertically divided sections, which optimizes airflow to the engine. Their unique form and aerodynamically advanced function are the result of more than 700 hours of wind-tunnel development time. And more than 50 years of accelerated learning on racetracks around the world—the ultimate design studio for any Porsche.

Even at a complete standstill, the Cayman's seductively shaped rear wheel arches and wide rear track reveal a flare for the kind of highly spirited performance that engages all of your senses. Its wide hips provide ample space for boldly emphatic taillights in back and signature wheels endowed with high-performance tires that rivet all four corners to the pavement. A biplane spoiler that automatically extends at speeds above 75 mph provides still greater adhesion by generating extra downforce that contributes to a top track speed of 171 mph for the Cayman S and 160 mph for the Cayman (manual transmission). A less dynamic, but no less rewarding, feature is the large rear hatch. Its top-hinged lid offers convenient access to 9.2 cubic feet of generous storage space, ensuring that no road trip in your Porsche Cayman need be cut short.



Performance
The 24-valve flat-six boxer engine engineered specifically for the Cayman achieves each objective. Its low center of gravity augments the superb chassis in which it resides. The two-piece block is diecast in lightweight aluminum with integrated oil and water channels. This simple solution eliminates the need for drilling or external hoses, possible sources of failure. Other solutions are more complex: The crankshaft bearing bridge, for example, is a composite structure of two metals: aluminum to cut weight, and cast-iron inserts to reduce temperature- related changes in bearing play.

The 2.7-liter engine in the new Cayman generates 245 horsepower, while 201 lb.-ft. of torque arrives at just 4600 rpm and stays with you to 6000 rpm. The Cayman S is armed with 3.4 liters of total swept volume and a maximum of 295 horsepower at 6250 rpm. Maximum torque is 251 lb.-ft. at 4400 rpm.

Such power is derived from a two stage resonance induction manifold that optimizes the air charge as rpm's rise, and by our patented VarioCam Plus, which adjusts valve timing and lift. Naturally, high-tech electronics also play a role. Fuel injection and ignition are controlled by the Motronic ME 7.8 engine management system, while an electronically operated throttle applies power with precision.

Manual Gearbox
At the controls of a Cayman, every driver input is met with an immediate and smooth response. Perhaps nowhere is this more evident than the performanceoriented six-speed transmission. (posted on conceptcarz.com) Rapid shifts are executed through a short-throw mechanism designed to let you extract maximum torque from each of the ideally spaced gear ratios. The gearbox is driven through a dual-mass flywheel that minimizes noise in the drivetrain. Noise is further reduced by the cable-operated gear linkage which insulates the lever from the engine and gearbox.

Chassis
These sculpted forms represent the ultimate evolution of Porsche suspension design. Their sporting prowess is derived not from technological tricks that dampen a driver's feel of the road, but from sound geometry and the finest lightweight materials. MacPherson-type coil-over struts work in conjunction with lateral control arms to give the Cayman its characteristic feel when driving through twists, around turns and over bumps. The car's generous track (the distance across each axle) minimizes pitch and roll, with stout anti-roll bars also contributing to remarkably flat cornering.

Virtually all moving parts in the axle assemblies are forged from light yet-robust aluminum to minimize unsprung mass. Equally important, these axle assemblies are attached to a highly rigid bodyshell.

Wheels
Naturally, our love of curves isn't confined to rooflines and fender flares. Porsche engineers have developed lightweight alloy wheels specifically designed to help a Cayman make the most of every long, winding road.

Both Cayman models are fitted with strong, ultralight alloy wheels that improve overall handling and traction. The new Cayman comes with 17-inch wheels as standard, while the Cayman S is equipped with 18-inch alloy wheels, sporting a purposeful five-spoke design inspired by the Porsche Carrera GT. A variety of striking wheel designs is available as options on both models. Anti-theft bolts are standard.

An optional Tire Pressure Monitoring System (TPMS) provides early warning of any drop in pressure with an alert on the onboard computer display.

Steering
With its superb mid-engine weight balance and race-bred suspension, the Porsche Cayman demands a responsive steering system tuned to the task. Our engineers responded with variable-ratio rack-and-pinion steering.

In the straight-ahead position, the ratio is less direct, which enables smoother high-speed maneuvers and effortless control. Turn the wheel harder—the ratio becomes more direct in a linear, progressive fashion, thereby quickening the response. The front wheels actually travel further relative to the amount that the steering wheel is turned, resulting in more agile cornering and easier parking.

This hydraulically assisted system delivers rewarding two-way communication between man and machine—responding with thrilling immediacy to every input while allowing drivers to read nuances in the road with the aid of exceptional tactile feedback. Wrapped in hand-stitched leather, the standard three-spoke steering wheel adjusts for both height and reach to assure comfort for drivers of all statures.

Suspension
For the ultimate in comfort and control, both Cayman models can be equipped with Porsche Active Suspension Management (PASM). This advanced option continuously adjusts the damping force at all four corners of the car to suit your driving style and changing road conditions.

With PASM installed, the Cayman's ride height is lowered by 10 mm versus that of its standard steelsprung suspension. The driver can select one of two setup modes—'Sport or Normal'—with the press of a button. Normal offers an ideal mix of performance and comfort, while the Sport setup features a firmer range of settings for even greater performance capabilities.

In either mode, PASM reacts to both changes in the road and your driving style by varying damping force at each wheel.

A series of sensors is used to monitor all movements of the car's body. The PASM control unit then evaluates this data and modifies the damping force on each of the wheels to reduce pitch and roll for more consistent road-holding.

Should road-surface quality drop below a certain threshold while in Sport mode, PASM immediately shifts to a softer rating within the Sport setup band to restore grip and traction. When road conditions improve, the firmer Sport settings are automatically restored.

PASM is equally responsive to your style of driving. If Normal mode is selected and the car is driven in an assertive manner, PASM will switch to a firmer rating within the Normal setup band. Stiffening the dampers makes the car more stable and more responsive to driver input. In either case, the result is a driving experience that instantly adapts for optimal performance and enjoyment.

Safety
Generous reserves of active safety are a natural byproduct of Porsche engineering in both of the Cayman models. A poised and predictable chassis, powerful engine and faderesistant braking system featuring advanced ABS all combine for a driving experience that is as safe as it is spirited.

High-performance tires fitted on lightweight, aerodynamic wheels provide ultra-responsive handling, while a biplane spoiler that extends at speeds over 75 mph creates added downforce at speed for more accident-avoiding traction. Naturally, high technology also plays a role: The Cayman and Cayman S are both equipped with Porsche Stability Management (PSM), a driver's aid that helps you maintain control when emergency situations dictate. And carve cornering lines when deserted back-roads beckon.

The Porsche Cayman is designed to meet the world's most stringent crash-safety regulations for frontal, side, diagonal, rear-impact and rollover protection.

The bodyshell structure is designed around a highly resilient passenger cell designed for exceptional crash protection. Patented longitudinal and transverse members absorb and deflect frontal crash energy, reducing impact on the passenger cell. Super high-strength steel is used in the bulkhead to protect both front footwells and in the doorsto enhance the rigidity of the car for superior side-impact protection.

Intelligent design is also exemplified by an upper load path that is engineered to channel crash energy around the sides of the car and away from the passenger cell.

Braking System
The braking ability of the Cayman is every bit as impressive as its acceleration from 0–60 mph in 5.1 seconds (manual transmission).

Precise, reliable stopping power begins with massive brake discs. The Cayman S Brakes have a diameter measuring 12.52 inches in front and 11.77 inches at the rear, each disc is internally vented and cross-drilled for better fade resistance and improved braking in wet conditions. Airflow is an integral part of every Porsche braking system. Large ducts swallow cooling air and channel it to each brake assembly, helping lower temperatures for higher levels of performance.

A race-inspired monobloc design forged from a single block of aluminum and fitted with four pistons per caliper is engineered to be extremely rigid, robust and lightweight. The payoff? More consistent, more immediate pedal response. And a more gratifying driving experience.

The optional Porsche Ceramic Composite Brake (PCCB) system for the Cayman S, takes the science of braking to an entirely new level. The system's discs are not metal, but a special ceramic reinforced with carbon fiber. Initially created for race cars, using a complex manufacturing process, they are harder, more resistant to high temperatures, and about half the weight of metal discs.

Featuring significantly more cooling channels than conventional discs, PCCB brakes are designed with a vent geometry that accelerates airflow to maximize cooling under heavy brake use. This design also incorporates more internal walls for greater structural stability.

The carbon-composite discs work in concert with a special brake-pad compound to deliver rapid deceleration and consistent friction properties. Powerful six-piston monobloc calipers are fitted on the front brakes, with four-piston monobloc calipers at the rear of the vehicle. A distinctive race-yellow color offers visual evidence of the power lying in wait at all four corners.

Stability Management
While it can't overcome the laws of physics, the revolutionary Porsche Stability Management (PSM) system does lend an added degree of balance and control to the Cayman's mid-engine driving dynamics, inspiring surefooted confidence in corners and extreme situations.

A standard feature on the Cayman and Cayman S, PSM continuously monitors steering input, road speed, yaw velocity and lateral acceleration to calculate the actual direction of travel. If the car begins to steer off line, PSM instantly intervenes with precision brake inputs on individual wheels to help bring the car back onto the driver's intended path.

If braking alone isn't enough to correct the vehicle's cornering line, PSM then calls on the Cayman's engine management system, adjusting engine output as needed to help stabilize handling. PSM can also compensate in an instant for mid-corner changes in load resulting from deceleration or braking. When Sport mode is selected with the optional Sport Chrono Package, PSM's threshold for intervention is raised, allowing for greater driver involvement. If you prefer driving without automatic PSM assistance, the system can be set to standby at any time. In this case, it will only intervene under heavy braking, where both front wheels exceed the ABS threshold.

For all of its technical ability, PSM goes virtually unnoticed in everyday driving situations, preserving the Cayman's natural agility.

Airbags
Dual Advanced Airbags provide optimum upper-body protection in front with an added degree of intelligence: A weight sensor in the passenger seat automatically switches the passenger airbags off when unoccupied or fitted with a child seat.

With the standard Porsche Side Impact Protection (POSIP) system, Porsche takes a comprehensive approach to protecting passengers against side-impact collisions. Thorax-protection airbags located in the seat backrests are coupled with head-protection airbags that deploy upward from the driver and passenger doors. Each of the four airbags has a volume of about .28 cubic feet, which offers protection over the full seat-adjustment range. Side-impact beams in each door are also integral to the POSIP system.

You're never too young to enjoy a journey in the Porsche Cayman. For this reason, we've designed the passenger seat to work with any LATCH-compatible child seat. All of the necessary preparation, including a manual airbag deactivation system, is available from your Porsche dealer. Your dealer can also introduce you to a range of child seats, designed specifically for your Porsche, through the Tequipment collection.

Emission Control System
At Porsche, high performance and low emissions go hand in hand. We were the first manufacturer to fit race cars with catalytic converters, so it should come as no surprise that the Cayman meets California's stringent lowemission standard, LEV II. In fact, many of the same technologies that make the Cayman a great sports car also make it a green sports car.

The flat-six engine's four-valve cylinder heads and VarioCam Plus enhance the delivery of power, while simultaneously reducing emissions at the combustion source. After exiting the engine, the gases are cleaned by four catalytic converters and four Lambda oxygen sensors.

Each exhaust tract has twin Lambda sensors, located before and after the primary catalyst. Working in concert with the Motronic ME 7.8 engine management system, which uses sensor data to continuously optimize the air/fuel mixture, this technology delivers a seemingly endless supply of power with low emissions and better fuel economy.

Acoustics
A sign of precision engineering is the Cayman's coupling of high power output and low noise levels. Rather than rely on heavy sounddeadening, our engineers eliminate noise at its source. Rigid engine components, lightweight moving parts and tight tolerances prevent vibration and resonance. What greets the ear is the pure, distinct sound of a Porsche boxer engine.

Materials and Recycling
Porsche has always considered lightweight design essential in the development of high-performance sports cars. Úsing aluminum alloys, synthetic materials and high-tensile metals, we're able to build cars that are both lighter and stronger than those made of conventional steel—so they require less raw material to manufacture and burn less fuel on the open road.

All trim, switch gear and structural components are made from fully recyclable materials. In all, about 85% of the Cayman's components can be recycled using technologies available today. All synthetics have been clearly labeled to simplify the recycling process—provided, of course, that a Cayman is ever retired from the road.

The Cayman and Cayman S are both entirely free of CFCs. Waterbased paints are used throughout the vehicle, reducing the need for chemical solvents during its production.

Larger engine, bigger brakes and more boost dynamic capabilities - Cayman S

To take full advantage of its more rigid body structure and its expanded dynamic potential, the 2007 Porsche Cayman S is equipped with a large and powerful 3.4-liter, horizontally opposed six-cylinder engine. By unleashing this 295-horsepower engine in a lightweight but extremely stiff chassis built on nimble suspension, the 2007 Porsche Cayman S establishes a new benchmark in the two-seat sports coupe category.

New for 2007 is a revised an updated Tiptronic® S automatic transmission, a standard Tire Pressure Monitoring System (TPMS) and optional new 19-inch wheels with the same design as the 2007 911® Turbo.



Indeed, during testing at Germany's famed Nürburgring racing circuit, the Cayman S turned laps that rivaled even the acclaimed Porsche 911® Carrera®, the epitome of the modern sports car.

The 2007 Porsche Cayman S is the higher-performance version of Porsche's Boxster-based sports coupe, and like all Porsche 'S' models, the changes are not some mere cosmetic package but changes significant enough to warrant a separate model designation.



But the 2007 Porsche Cayman S isn't just fast and quick around the road course. Thanks to careful engineering to optimize weight and to a design that provides outstanding aerodynamics, this Porsche coupe established standards on the Nürburgring's famous Northern Circuit for efficiency by turning the fastest lap while using the least amount of fuel. (concept carz)

And yet the 2007 Porsche Cayman S is more than a high-performance sports car. It was designed to be comfortable with a particularly well-appointed passenger compartment designed for long-distance driving -- whether on two-lane mountain roads, wide-open stretches of Interstate highway or even the congestion of urban freeways.

While the Cayman S chassis and suspension are based on the Boxster's, the coupe is slightly larger and gains rigidity from its fixed-roof architecture. This stiffer structure allows Porsche engineers to optimize the coupe's suspension for exceptional dynamic capabilities. Compared to Porsche's own outstanding roadster, the body of the Cayman S offers 100 percent more resistance to flex and its torsional stiffness nearly matches that of the heralded Porsche 911 Carrera.

The 2007 Porsche Cayman S features the latest generation of Porsche Stability Management (PSM), a unique vehicle control technology that comprises anti-lock braking, anti-slip (traction) control, engine drag control and automatic brake differential functions to intervene when necessary in driving situations that approach the limits of adhesion. In such instances, PSM can apply the brakes to individual wheels to help maintain the car's stability.

However, unlike intrusive vehicle control systems available from other automakers, PSM is designed not to interfere with sporty performance but to enhance the experience for the enthusiast driver.
For drivers who want to experience the ultimate expression of vehicle dynamics, the 2007 Porsche Cayman S can be equipped with Porsche Active Suspension Management (PASM) and the Sports Chrono Package.

PASM, in effect, provides two suspension setups in a single vehicle – one for comfortable cruising and everyday driving and the other for track-day or autocross exercises.

The Sports Chrono Package does not only include a dash-mounted stopwatch gauge that records lap times on track days or in autocross events, but it enhances the vehicle's performance in such an environment by allowing the driver to engage more aggressive electronic control maps for the Motronic engine management system, Porsche Stability Management (PSM), Porsche Active Suspension Management (PASM) and Tiptronic S transmission (on vehicles equipped with these options).
In Porsche's testing at the Nurburgring, a Cayman S equipped with the Sports Chrono Package was some three seconds per lap faster around the test track.

To deal with such dynamic forces, the Cayman S uses the same braking system components as the 911 Carrera, and rides on standard 18-inch wheels and tires, with four 19-inch wheel designs as optional equipment.

To try to classify the Cayman S as merely the coupe version of the Boxster does disservice to both vehicles, each of which is unique with its own special characteristics. The 2007 Cayman S presents a new face for Porsche with a more pronounced lower lip and with the fog lamps mounted on bars that extend across the air intakes – with their unique vertical slats -- on either side of that lap. The hood sweeps up between the front fenders to a steeply raked windshield.

Overall, the 2007 Porsche Cayman S body is 172.1 inches (4372 mm) long, which makes it not quite half an inch longer than the Boxster and 3.5 inches (88.9 mm) shorter than the 911 Carrera. The Cayman S also is half-an-inch taller (at 51.4 inches or 1305 mm) than the Boxster, though the cars share their width (70.9 inches or 1801 mm) and their 95.1-incn (2415 mm) wheelbase dimensions.
The interior of the 2007 Porsche Cayman S combines luxury-class materials with the controls and seat bolstering required by the enthusiast driver and thus provides a fitting environment whether traveling across the country or around a racetrack.
