BMW has the lowest average CO2 emissions of any premium car manufacturer for the second year in a row, according to new independent research in the UK. Courtesy of its award-winning EfficientDynamics program, BMW records a fleet average of 159.4g/km based on all BMWs sold in in the UK in 2008.
By comparison, the research by cleangreencars found BMW's premium rivals wanting when it came to cutting CO2 emissions. The volume weighted CO2 emissions figure for Audi is only 173g/km, while Mercedes-Benz records 189.9g/km, Jaguar 198.3g/km, Land Rover 251g/km and Porsche 271.7g/km. The total industry volume average for 2008 is 158.7g/km.
It was a similar story in 2007 when BMW recorded a segment leading average of 177.5g/km - itself a substantial improvement from the figure of 190.3g/km in 2006.
Currently 21 BMW models on sale in the UK emit less than 140 grams of CO2. BMW first offered EfficientDynamics as standard in 2007. A raft of models received Auto Start/Stop, Brake Energy Regeneration, Active Aerodynamics, low rolling-resistance tires, Electric Power Steering, on-demand of ancillary systems and optimum gearshift indicator features. These built on the existing lightweight engineering principles and direct-injection engine technology introduced over the previous few years.
News of a record low in BMW car emissions comes as the impact this technology is having on the environment has been revealed. EfficientDynamics-equipped BMWs sold in the UK during the last two years have been responsible for an approximate 58000 tonne reduction in CO2 emissions. Models graced with the new technology since 2007 recorded improvements in fuel consumption by up to 24%, with emissions down by up to 21% compared to 2006 models.
Unfortunately, many of the EfficientDynamics technologies are not currently available to US customers, nor are the smaller gasoline- and diesel-powered vehicles that bring down the BMW fleet's average emissions. However, it does underline the manufacturer's commitment to the environment and US customers can look forward to more of this technology arriving soon.
