Environmental Record

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 19 miles (31 km) all-electric range and CO₂ emissions of 74 grams/km in the New European Driving Cycle.

Since 2002, Mercedes-Benz has developed the F-Cell fuel cell vehicle. The current version, based on the B-Class, has a 250 mile range and is available for lease, with volume production scheduled to begin in 2014. Mercedes has also announced the SLS AMG E-Cell, a fully electric version of the SLS sports car, with deliveries expected in 2013. The Mercedes-Benz S400 BlueHYBRID was launched in 2009, and is the first production automotive hybrid in the world to use a lithium-ion battery. In mid-2010, production commenced on the Vito E-Cell all-electric van. Mercedes expects 100 vehicles to be produced by the end of 2010 and a further 2000 by the end of 2011.

In 2008, Mercedes-Benz announced that it would have a demonstration fleet of small electric cars in two to three years. Mercedes-Benz and Smart are preparing for the widespread uptake of electric vehicles (EVs) in the UK by beginning the installation of recharging points across their dealer networks. So far 20 Elektrobay recharging units, produced in the UK by Brighton-based Elektromotive, have been installed at seven locations as part of a pilot project, and further expansion of the initiative is planned later in 2010.

In the United States, Mercedes-Benz was assessed a record US$30.66 million for their decision to not meet the federal corporate average fuel economy standard in 2009. Certain Mercedes-Benz cars including the S550, and all AMG models sold in the United States also face an additional gas guzzler tax. However, newer AMG models fitted with the M157 engine will not be subject to the gas-guzzler tax due to improved fuel economy, and newer models powered by the M276 and M278 engines will have better fuel economy. In 2008, Mercedes also had the worst CO₂ average of all major European manufacturers, ranking 14th out of 14 manufacturers. Mercedes was also the worst manufacturer in 2007 and 2006 in terms of average CO₂ levels, with 181 g and 188 g of CO₂ emitted per km, respectively.
