Highlights of the 2012 Mercedes-Benz M-Class include 4MATIC permanent all-wheel drive, new developments to the chassis and innovative driving dynamics, all of which improve performance in both on-road and off-road situations. It features the new active and passive safety features that are now familiar for Mercedes-Benz. A characteristic body design together with a comfortable and versatile interior enhances the driving experience in the new M-Class.
The all-new 2012 Merceds-Benz M-Class will make its U.S. retail debut in September 2011 and includes two models: ML350 4MATIC and ML350 BlueTEC.
State-of-the-art engines and a comprehensive range of fuel efficiency measures all contribute to delivering superb energy efficiency. BlueTEC diesel engines and the new generation of BlueDIRECT gasoline engines provide the starting point for the excellent efficiency of the new M-Class.
The Mercedes-Benz ML350 BlueTEC uses a completely reworked 3.0-liter V6 engine, which meets emissions standards in all 50 states and delivers far better performance, yet with considerably reduced fuel consumption. The efficiency improvements have been achieved, above all, through the use of the innovative TWAS (twinwire- arc spraying) technology – in use since 2005 in AMG’s successful highperformance engines. The positive results at AMG have led Mercedes-Benz to adapt this cylinder wall coating technology for use in the V6 diesel engine as well. The process reduces internal friction in the engine significantly. At the same time, the weight has been reduced by 9.5 lbs., as there is no longer any need for the grey cast iron cylinder liners that, until now, had to be pressed into the engine block. The benefits are striking: with these measures alone, fuel consumption could be reduced by around 3 percent.
The Mercedes-Benz ML350 4MATIC gasoline-engine model, on the other hand, delivers impressive performance thanks to the new BlueDIRECT engine generation. The key is direct gasoline injection system with spray-guided combustion and new piezo injectors that have an injection pressure of 2,900 psi, together with fast, multi-spark ignition and a new combustion process.
