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.

It isn't a given that the companies that provide mobility today will also be the ones to do so tomorrow. Every company has to work hard to make this happen.

As far as I'm concerned, however, it is clear that the concept of premium will be increasingly defined through sustainability in the future.

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.

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.

As far as I'm concerned, it is clear that the concept of premium will be increasingly defined through sustainability in the future. BMW, like no other brand, will still stand for vitality and driving pleasure in the future. But it will also represent efficiency and environmental friendliness.

We will introduce an electric car by 2015. It will be a completely new vehicle concept for mega-cities. We would also have it developed if, contrary to expectations, it did not turn a profit in its first life cycle.
