New European Driving Cycle
Mercedes-Benz has developed multi-concept cars with alternative propulsion, such as hybrid-electric, fully electric, and fuel-cell powertrains. At the 2007 Frankfurt motor show, Mercedes-Benz showed seven hybrid models, including the F700 concept car, powered by a hybrid-electric drivetrain featuring the DiesOtto engine. In 2009, Mercedes-Benz displayed three BlueZERO concepts at the North American International Auto Show. Each car features a different powertrain - battery-electric, fuel-cell electric, and gasoline-electric hybrid. In the same year, Mercedes also showed the Vision S500 PHEV concept with a all-electric range and emissions of 74 grams/km in the New European Driving Cycle.
