Prestige and premium will also play an important role in the future. But some people define these values differently today.

In the European Union, a fleet average of 95 grams of CO2 per kilometer will be permitted in 2020. This corresponds to fuel consumption of about four liters (per 100 kilometers; about 59 mpg). We have to continue reducing the fuel consumption of our vehicles and offer hybrid and electric vehicles, or else we will be unable to achieve these values.

Size alone is not a key to success, as we have seen recently.

There were certainly those who rubbed their eyes in astonishment. But when we held a company discussion forum with Joschka Fischer, interest was high. Six hundred senior managers came to the meeting. In the end, there was tremendous applause for Fischer, because he offered a precise analysis of the challenges our industry faces worldwide.

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. A few years ago, the CO2 emissions for the BMW brand were at well over 200 grams per kilometer. In 2009, that number was at 159 grams. This puts us below our direct competitors.

The manufacturers of mechanical typewriters believed that they had developed sufficiently when they introduced electric typewriters. Then came the PC, and the deeply traditional makers of typewriters disappeared from the market.
