BMW confirmed as UK's cleanest auto maker

In an independent industry-wide study conducted by www.cleangreencars.co.uk, BMW's model range emerged the cleanest of premium auto makers in the production of CO2 emissions. Additionally, the data showed BMW also had the most improved CO2 emissions average of any premium manufacturer.

Looking into the average emissions of each premium auto maker, it was found that from the period between January 2008 to June 2008, BMW recorded an average of 161.64g/km. By comparison, the model range average for Audi and Mercedes-Benz were 177.36g/km and 192.85g/km respectively. Even Lexus, with its hybrid-based model line-up, only managed an average of 194.85g/km, while Jaguar topped 200g/km. Porsche recorded the poorest average of 275.64g/km.

Additionally, over the same time frame, BMW improved its average emissions by 11.34%, compared to Audi by just 5.78% and Mercedes-Benz by 4.13%. Lexus and Jaguar only improved by 2.16% and 2.04% respectively, while Porsche actually increased its average model range emissions by 0.63%.

BMW has been touting this achievement for the past few years through its EfficientDynamics programme. In an effort to keep ahead of EU guidelines, BMW's future plan include NOx storage capability within a catalytic converter. Engineers are also finalizing drivetrain configurations to meet the likely EU6 legislation due to come into effect in 2014.
