Mercedes-Benz R-Class Features Fuel Economy, More

R350 4MATIC Fitted New Direct-Injection V6 Engine

The 2012 R350 4MATIC features an 3.5-liter direct-injection V6 engine horsepower, 273 lb.-ft. of torque) wîth a more fuel seven speed automatic (posted on conceptcarz.com) Thanks to new powertrain the R350 4MATIC now significantly better fuel (16 city / 21 highway) while more power – an impressive considering that increasing power or fuel economy decreases the other. The R-Class is available wîth a fuel-sipping diesel engine (210 hp, 400 that is offered in all 50 states.


New to the 2012 model year, the model line now features LED daytime running lights, to the interior and helpful directional for the standard rearview camera. A system featuring hard-drive four gigabytes of music SIRIÚS/HD radio, SIRIÚS traffic updates, Gracenote Database, Zagat® Survey guide guides and voice now come as standard on all models.

More Fuel-Efficient Transmission

The R-Class line is equipped a new 7-speed automatic transmission has a more advanced torque lock-up clutch that even better fuel more responsive driving, operation and increased durability. The new is also designed to work wîth a new type of low-viscosity ATF fluid – colored blue of the usual red. Together new planetary gears, bearings and seals, the ‘FE-ATF’ fluid less friction and improved mileage. Lower hydraulic and enhanced electronic software provide even smoother

Details on the New V6 Engine

The new 3.5-liter V6 features direct fuel and multi-spark ignition. The V6 engine is in a new block wîth 60-degree angles, so that a balance isn’t needed for smooth Like its predecessor, the new engine has cylinder heads, pistons and block (with cast-in cylinders), as well as a crankshaft, roads and valves made of forged steel.

Direct Injection

While most engines have used port fuel injection in the the new V6 makes use of -leading electronics first used on Mercedes-Benz – electronic fuel injectors spray gasoline directly the combustion chambers.

Featuring a piezo-ceramic crystalline that changes shape when electrical current is blazingly fast piezo make it possible to design sensitive and precise injection including the ability to program small injections wîth piston ….

The first is sprayed into the combustion as the piston is descending on the intake Depending on speed, load and conditions, another injection or two place during the compression before ignition, forming a mixture. A fourth injection can combustion if it’s needed.

Multi-Spark Works wîth

Working together wîth injection, a rapid multi-spark system begins combustion the first spark, but has the capability to and deliver up to three more within a single millisecond, a gas plasma wîth more than conventional ignition. The lapse between sparks is so combustion duration can actually be resulting in two percent better economy, and a total of four improvement in combination wîth fuel injection.
