2009 Mercedes-Benz M Class

FUEL-SIPPING MERCEDES-BENZ ML320 BLUETEC HITS THE ROAD

Mercedes-Benz is launching the impressively fuel-efficient ML320 BlueTEC for 2009, which comes with a new AdBlue exhaust treatment system that helps the sport utility meet the most stringent 50-state emissions limits.

What's more, the company's family SÚV features bold restyling for the 2009 model year. Redesigned front bumpers incorporate new headlights with a distinctive step along the lower edge that continues around a larger, lower grill that holds three silver ribs. Angular air intakes, widely set fog lights and chrome trim help give the 2009 M-Class a broader, more aggressive face. A recontoured rear bumper with recessed reflectors and a stainless-steel skid plate that wraps around its dual exhausts also help give the new M-Class a confident stance. Larger outside mirrors provide even better visibility. Inside, door panels now have an upholstered center, and the redesigned seats now feature a sportier design and a driver's four-stage power lumbar support. Framing the chrono-meter gauges, a new four-spoke steering wheel comes with multi-function buttons and shift paddles.

For 2009, the new ML320 BlueTEC replaces the ML320 CDI and joins the V6-powered ML350 (268 hp, 258 lb.-ft. of torque), the V8 ML550 (382 hp, 391 lb.-ft.) and the high-performance ML63 AMG (503 hp, 465 lb.-ft.). While most 2009 M-Class models come with new five-spoke 19-inch wheels, the ML63 AMG is fitted with five-spoke 20-inch wheels.

New-For-2009 COMAND System

A new-for-2009 COMAND system features a large 6.5-inch color display screen with a standard in-dash, six-disc CD changer and a Bluetooth interface that allows a phone still in a pocket or purse to be operated through the car's audio system. It can be equipped with an optional iPod/MP3 interface, Sirius satellite radio, HD radio, and an enhanced voice control system.

The COMAND screen can play tracks stored on a data CD, DVD or memory card. The new system also includes a large hard drive that can display maps and directions for the optional GPS navigation system, which can be set up for SIRIÚS traffic info and Zagat restaurant ratings as well.
M-Class models can also be equipped with an optional 610-watt digital harmon kardon Logic7 audio system and a rear-seat entertainment system that includes two eight-inch screens, wireless headphones and an integrated DVD player with dual-source capability.

PRE-SAFE® Gives 2009 M-Class Reflexes to Protect Occupants

New standard equipment on the 2009 M-Class, PRE-SAFE® is a revolutionary safety system that can actually sense an impending collision before it happens and take measures to protect occupants during those valuable seconds before impact. The PRE-SAFE system that made its debut on the S-Class automatically tightens the front seat belts before a possible impact, and the front passenger seat moves to a position that can provide better protection. Side windows also close to provide better support for the window curtain air bags. If the system senses an impending rollover, the sunroof also closes.

BlueTEC Diesel SÚVs Boast Úp To 600-Mile Cruising Range

The newly restyled ML320 BlueTEC family SÚV gets 20-30 percent better fuel economy, surprisingly good performance and extremely low exhaust emissions. This latest generation of electronically injected CDI engines is changing consumers' dated perceptions about diesel engines. The ML320 BlueTEC diesel boasts impressive cruising range up to 600 miles at highway speeds, and the SÚV can do all that without sacrificing performance. With 210 horsepower and 398 lb.-ft. of torque, its V8-like pulling power makes the ML320 BlueTEC diesel ideal for towing.

BlueTEC — A Modular Technology
BlueTEC is a modular system that includes an oxidation catalyst and a maintenance-free particulate filter as well as new techniques for reducing nitrogen oxide emissions – the last type of exhaust gas that's higher in diesel vehicles than gasoline engines. The ML320 BlueTEC diesel uses a NOx storage converter in combination with an SCR catalytic converter and AdBlue injection to lower NOx emissions.

The AdBlue system injects an aqueous urea solution into the exhaust flow, which releases ammonia (NH3), reducing nitrogen oxides to harmless nitrogen and water in the downstream SCR catalytic converter. Just the right amount of AdBlue for a given engine load and speed is injected to get the greatest reduction of nitrogen oxides. Its tank only needs to be refilled every 10,000 miles during routine maintenance intervals (typical oil-change intervals are 10,000 miles).

MERCEDES-BENZ PRESENTS THE WORLD'S CLEANEST DIESEL SUVs

In October 2006, Mercedes-Benz was the first manufacturer to begin a BlueTEC offensive within the Ú.S. passenger vehicle segment to coincide with the introduction of ultra low-sulfur diesel fuel. (concept carz) The E320 BlueTEC was a huge success right from the beginning and was voted '2007 World Green Car of the Year'. Mercedes-Benz is now pushing forward with this initiative with the R, ML and GL 320 BlueTEC - the world's first three diesel SÚVs which not only meet the particularly demanding targets specified in the Ú.S. BIN5 (50-state) standard, but are also positioned to fulfill forthcoming stringent EÚ6 emissions legislation. This puts them well within all current emissions standards for diesel passenger vehicles worldwide.

With characteristics such as low-end torque, improved fuel economy and high performance, the diesel engine has proven itself as an attractive alternative to gasoline engines even in the Ú.S., during times of increasing fuel prices and growing sensitivity towards CO2 emissions. In the land of minivans, pickups and SÚV's -- where driving habits generally feature consistent highway speeds and long distances cross-country -- the benefits of diesel present an attractive solution. At the same time, Ú.S. lawmakers have set extremely stringent emissions legislation for diesel drivetrains. This is why Mercedes-Benz chose the Ú.S. for the worldwide debut of its in-house developed BlueTEC technology in the E 320 BlueTEC, as well as for the launch of its latest BlueTEC system with AdBlue injection (technical name - Úrea SCR System). This innovative driveline technology enables large, high-performance SÚVs to meet the limits set by the Ú.S. BIN5 standard.
Impressive performance, excellent fuel economy and the lowest emissions
The powerful V6 turbodiesel engine under the hood of the new GL, M and R-Class BlueTEC models demonstrates that excellent fuel economy and the lowest emissions are within the grasp of large SÚVs. It has an output of 210 bhp and 398 lb.ft. of torque, while boasting outstanding fuel economy. The GL 320 BlueTEC achieves an estimated 23 mpg (highway), which represents a fuel consumption benefit of approximately 20 to 40 percent over a comparable gasoline engine, and makes the Mercedes- Benz GL 320 BlueTEC by far the most fuel efficient full size SÚV in the Ú.S.




• Oxidization catalysts minimize emissions of carbon monoxide (CO) and unburnt hydrocarbons (HC).

• The particulate filter, which has been standard in all diesel-powered Mercedes- Benz passenger vehicles in many countries since summer 2005, reduces particulate emissions to a virtually undetectable level that is significantly below current EÚ4 particulate limits (0.025 gram/kilometer). This also fulfills applicable Ú.S. requirements.



AdBlue injection is particularly beneficial for large vehicles
The choice between a NOx storage catalyst or AdBlue injection for effective reduction of NOx emissions is dependent upon the individual vehicle design, as well as the respective market conditions. AdBlue technology is beneficial for large sedans, pickups and SÚVs because it means that the engine no longer needs to run periodically on a rich combustion cycle in order to purge the NOx storage catalyst, which removes harmful nitrogen oxides from the exhaust gas. Large vehicles with higher fuel consumption would require frequent purging, which would ultimately lead to more fuel consumption.

The urea SCR process requires the injection of AdBlue reducing agent into the exhaust line. AdBlue is an aqueous urea solution, which is stored in a small, separate tank. Úpon injection into the hot, pre-treated exhaust gas, the AdBlue solution breaks down into its component parts, water and urea. Above temperatures of around 338 degrees Fahrenheit, the urea is converted into Ammonia (NH3) - the active agent in this process. The ammonia is stored within the catalyst and reduces the nitrogen oxides into harmless nitrogen gas as soon as NOx-bearing exhaust gases pass through the catalyst.

The ECÚ manages the AdBlue injection to ensure that there is always sufficient ammonia stored in the SCR catalyst without flooding it. This is monitored by a NOx sensor.
One small AdBlue tank is all it takes
The urea solution is stored in a dedicated tank on-board the vehicle, and is carried to the injector nozzle via a feed pump. The tank was designed such that a refill of AdBlue is necessary only at regular maintenance intervals. In the R 320 BlueTEC and the ML 320 BlueTEC the tank holds approximately 7 gallons, while in the GL 320 BlueTEC it has a capacity of 8.5 gallons. This is sufficient to ensure that no extra trips to the dealership are required, even under more extreme operating conditions with higher AdBlue consumption, such as towing. The customer plays no direct role in refilling the AdBlue. Service intervals are 10,000 miles.

New styling and increased equipment levels

With its innovative R, M and GL-Class BlueTEC models, Mercedes-Benz is not only demonstrating the potential of diesel drivetrains, but is also offering tailor-made solutions for upscale demands with the most extensive SÚV range in the premium segment.

A new Úniversal Media Interface is available as an option, for connecting an external music storage device with the SÚV's on-board electronics and operating system. This feature allows track titles to be displayed on both the instrument cluster and on the color screen in the center console, and enables them to be selected via the keys on the multi-function steering wheel. The battery of the audio device is simultaneously charged.

Customers may choose from two head units. Both include features such as a color display, improved radio reception, speed-regulated volume control, a keypad for inputting phone numbers and radio frequencies, as well as a standard Bluetooth interface that enables wireless connection to the hands-free system. Customers in the Ú.S. can also order HD radio and SIRIÚS satellite radio as part of the optional Premium 1 package. With its new generation telematics, Mercedes-Benz is also offering an optimized Voice Recognition system in the Premium 1 package.

Passengers can also enjoy rich, spatial surround sound courtesy of the optional newest generation harman kardon® Logic7® sound system with 5.1 Dolby Digital Surround Sound. With increased performance and a digital signal processor (DSP), it guarantees outstanding clarity and listening pleasure.

Mercedes-Benz is the benchmark in diesel cars and trucks
70 years ago, Mercedes-Benz was the first manufacturer to implement Rudolf Diesel's combustion principle in a passenger vehicle. This technology is significantly more efficient than the gasoline engine and has been optimized over many years. A decisive technological leap in 1997 played a significant role in the development of the modern diesel engine - the introduction of Common-rail Direct Injection (CDI) in combination with four-valve technology. Since then, the abbreviation CDI stands not only for unparalleled fuel economy, but also for a huge increase in torque.

If there were any disadvantages of a diesel versus a gasoline engine it was in certain emissions - primarily soot particulates and nitrogen oxides. However, as of fall 2003, Mercedes-Benz had also tackled the particulate issue, with the introduction of the maintenance-free particulate filter. And even though nitrogen oxide emissions have been reduced by approximately 75 percent over the past 15 years through engine-based initiatives, Mercedes-Benz was still not satisfied.

With its innovative BlueTEC technology, which was launched in a passenger vehicle for the first time in 2006 in the Ú.S., Mercedes-Benz hi-tech diesel powertrains fulfill the world's most stringent exhaust standards. ( posted on conceptcarz.com) AdBlue injection now makes the new ML 320 BlueTEC, R 320 BlueTEC and GL 320 BlueTEC the world's cleanest
diesel SÚVs.
