European carmakers pledged to reduce CO2 emissions by 25 percent from 1995 to 2008. We kept our word and reduced the value even more. This is not the result of short-term gimmickry. We decided years ago to develop the relevant models and engines, otherwise we wouldn't be able to offer them today.

Statistics compiled by the German Federal Motor Transport Authority highlight how successfully we have reduced fuel consumption.
