New Mercedes-Benz SL and E-Class Hybrids Make their World Debut at the 2012 NAIAS

Launching the world’s most fuel-efficient full-size car and a brand-new groundbreaking roadster is not a bad way to draw people to your stand and that’s exactly what Mercedes-Benz did at the 2012 Detroit Motor Show with the two hybrid versions of the E-Class and the sixth generation of the SL roadster.

The diesel-powered E300 BlueTEC Hybrid returns a fuel economy of 4.2 lt/100 km on the European combined cycle (54.6mpg US). Its powertrain combines a four-cylinder turbodiesel engine with an output of 204HP and 500 Nm (368.7 lb-ft) of torque with a 20 kW (27HP) and 184.3 lb-ft (250 Nm) electric motor, and features an auto stop/start system, regenerative braking, a pure electric mode and a “sailing” function.

Since diesel models are not yet popular in the North American market, Mercedes also launched the E 400 Hybrid as well. The internal combustion unit is a 306HP and 272.9 lb-ft (370 Nm) V6 that runs on gasoline fuel, while the electric motor is the same as the E 300 BlueTec’s. The E400 Hybrid’s average fuel economy in accordance with American CAFE standards is 27 mpg (8.7 lt/100 km).
