Politicians in Europe want change. The United States and China will follow this trend. One could see this is a threat, but it's also an opportunity. We at BMW want to take advantage of this and, through innovations, place ourselves at the forefront.

I have told our senior executives that I will slaughter holy cows if it benefits the company's long-term success. When we asked ourselves whether Formula 1 still matched the concept of a sustainable company, the clear answer was no.

BMW models are more powerful on average than competitors. This is precisely what we are aiming for: less fuel consumption and more driving pleasure.

If you, as CEO, have recognized an approach as being the right one, you have to pursue it consistently, even if some people disagree. But it is now clear to everyone that we, as an automaker, have no alternative but to take [environmental protection] course.

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.

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.

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.
