2010 MBZ E-class at the 2009 Detroit auto show

North American International Auto Show (NAIAS), Detroit, MI – At an off-site reception, the Detroit’s  Book Cadillac Hotel, the night before the Detroit auto show Mercedes-Benz’s Dr Z unveiled the new E-Class sedan. For those of you not in the know, Dr Z is the venerable Dr. Dieter Zetsche, Chairman of the Board of Management of Daimler AG and Head of Mercedes-Benz Cars.

Mercedes says the four- and six-cylinder engines are common rail diesel injection (CDI) unit’s, and consume up to 23 percent less fuel than before. The combined New European Driving Cycle (NEDC) consumption of the new four-cylinder diesel engines is just 5.3 liters per 100 kilometers, which corresponds to 139 grams of CO2 per kilometer. Mercedes also has common rail gasoline injection unit’s (CGI) that consume 20 percent less fuel than before.

The range of engines available for the new E-Class comprises four, six and eight-cylinder unit’s with outputs from 100 kW/136 hp to 386 kW/525 hp.

That 525 horsepower from Mercedes-AMG is the new high-performance E63 AMG. The V6 and V8-models are equipped with a seven-speed automatic transmission, once again, helping with fuel efficiency.

The strategy is to replace to replace large, naturally aspirated engines with turbocharged unit’s. The fuel efficiency was created by what Mercedes calls Blueefficiency.

This blueefficiency package includes better tooling and more work in the wind tunnel, creating a more aerodynamic car.  It also includes Eco start/stop function, which switches the engine off when it is idling.

All the engines for the new E-Class meet the EU5 emission standard, and in the case of the E 350 BlueTEC the emissions are already below the EU6 limit’s planned for 2014 .
