Constant optimization: Internal combustion engines are the mainstay of mobility
The first of three focal points on Daimler’s “road map” is the optimization of vehicles with internal combustion engine. Constant improvements and new developments are making gasoline and diesel engines not only more powerful, but above all more efficient and cleaner: According to a recent ACEA study, 100 modern vehicles produce less emissions on average than one single automobile from the 1970s. The diesel consumption of heavy-duty vehicles has been reduced by more than one-third.
With BLUETEC, Daimler has been offering clean diesel technology in commercial vehicles since 2005 and – in an adapted version – also for passenger cars since 2006. As well as reducing pollutant emissions, BLUETEC also cuts fuel consumption by two to five percent; this means up to 2,000 liters less diesel consumption per vehicle and year. This technology also constitutes the basis for compliance with the next stage of Euro 6 emissions legislation; and it is the key to our trucks’ and buses’ compliance with the stringent EPA 10 limits of the NAFTA states and JP 09 in Japan.
In passenger cars too, Daimler is the pioneer of efficiency. The most economical model of the new-generation Mercedes-Benz C-Class is now even more fuel-efficient: The C 220 CDI with manual six-speed transmission and standard ECO start / stop function consumes only from 4.1 to 4.4 liters of diesel fuel per 100 kilometers (fuel consumption combined cylce)* – 0.4 liters less than in the past. This is equivalent to combined CO2 emissions from 133 to 117 grams of CO2 per kilometer (energy efficiency class: a)*. The world’s most fuel-efficient luxury sedan with internal combustion engine, the Mercedes-Benz S 250 CDI BlueEFFICIENCY, offers the highest level of driving comfort and safety, but consumes just 5.8 - 5.5 liters per 100 kilometers (fuel consumption combined cycle, CO2 emissions combined: 151 - 146 g/km, energy efficiency class: A)*.
Gasoline models that are just as economical as diesels – this is made possible by the new generation of BlueDIRECT six- and eight-cylinder engines, which since 2010 have been successively introduced in numerous Mercedes-Benz model series. The power and torque of these engines have been increased over the predecessor versions, while consumption has been reduced by up to one-fourth. In terms of fuel economy, the state-of-the-art BlueDIRECT gasoline direct injection engines from Mercedes-Benz have come another step closer to matching the diesel power units.
The targeted BlueEFFICIENCY measures enhance fuel economy – especially with the ECO start / stop function, which is already standard in many vehicles and which Mercedes-Benz will offer in more than 50 models across its entire product range as of mid-2011. In the commercial vehicle sector, too, Daimler is shaping the future of mobility with its highly efficient, clean drive systems: With its “CleanDrive Technologies” for non-pollutant drive systems and alternative fuels, Daimler’s Commercial Vehicle division is shaping the future of mobility.
Already today, more than 500,000 vehicles from all the corporate truck, bus, and van brands are on the move throughout the world with “CleanDrive Technologies.” They illustrate various approaches to the ambitious aim of the zero-emission commercial vehicle.
Along with the clean, efficient BLUETEC technology for diesel engines, low-emission and quiet natural gas drive systems are a further option especially in city traffic. Alternative fuels also have the potential to cut emissions and to reduce our dependence on fossil energy sources.
