Mercedes-Benz
The 2012 Mercedes-Benz R350 4MATIC features an all-new 3.5-liter direct-injection V6 engine (302 horsepower, 273 lb.-ft. of torque) coupled with a more fuel efficient seven speed automatic transmission. Thanks to this new powertrain the R350 4MATIC now gets significantly better fuel economy (16 city / 21 highway) while producing more power - an impressive feat, considering that increasing either power or fuel economy usually decreases the other. The R-Class is also available with a fuel-sipping BlueTEC diesel engine (210 hp, 400 lb.-ft.) that is offered in all 50 states.
New to the 2012 model year, the R-Class model line now features standard LED daytime running lights, enhancements to the interior and helpful directional lines for the standard rearview camera. A COMAND system featuring hard-drive navigation, four gigabytes of music storage, SIRIUS/HD radio, SIRIUS real-time traffic updates, Gracenote Media Database, Zagat(R) Survey restaurant guide guides and voice control now come as standard on all models.
More Fuel-Efficient Transmission
The 2012 R-Class line is equipped with a new 7-speed automatic transmission that has a more advanced torque converter lock-up clutch that provides even better fuel mileage, more responsive driving, quieter operation and increased durability. The new transmission is also designed to work best with a new type of low-viscosity ATF transmission fluid - colored blue instead of the usual red. Together with new planetary gears, bearings and internal seals, the "FE-ATF" fluid provides less friction and improved fuel mileage. Lower hydraulic pressure and enhanced electronic software helps provide even smoother shifting.
Details on the New V6 Engine
The new 3.5-liter V6 engine features direct fuel injection and multi-spark ignition. The V6 engine is assembled in a new block with 60-degree cylinder angles, so that a balance shaft isn't needed for smooth operation. Like its predecessor, the new engine has aluminum cylinder heads, pistons and cylinder block (with cast-in Silitec cylinders), as well as a crankshaft, connecting roads and valves made of special forged steel.
