In 1998, we demonstrated the superiority of our diesel technology on the racetrack by winning the 24-hours of Nuerburgring in a race-tuned 320d Sedan. This grueling test of endurance not only proved the 320d's ability to run longer between fuel stops, but on a larger scale, demonstrated that performance and fuel efficiency are not mutually exclusive.

Today, we offer a wide variety of diesel engines across our entire model range in Europe. Taking home the prestigious Engine of the Year Award several times, our diesel engines are renowned for their unequaled harmony of dynamic performance, innovative technology, surprisingly low fuel consumption, along with a smoothness that is uncommon for a Diesel.



Clearly, this level of technology is predestined for the U.S. market, not only in terms of power and efficiency, but for its potential to help reduce greenhouse gas emissions. Which is why, in Fall 2008, we'll introduce two BMW Advanced Diesel with Blue Performance vehicles in the U.S. - the 335d and X5 xDrive35d. In addition to being better for the environment, these diesel engines also have increased torque. This enhanced concept for minimum exhaust gas emissions has been developed to meet the strict emissions standards in effect in California and other states. BMW's Blue Performance technology filters and actually cleans the exhaust before it leaves the vehicle, making this generation of Diesel engines the cleanest BMW has ever produced. With reduced emissions from comparable gasoline vehicles, and near-elimination of both smoke and NOx emissions, BMW Advanced Diesels will be every bit as clean as CARB-legal gasoline engines when they are introduced in the US in 2008.

As a means of producing so much power with a minimum of environmental impact and a maximum of fuel efficiency, it's no surprise that BMW will be among the first to introduce 50-state clean diesel technology. After all, it often takes an independent company like ours to bring an idea like this to the public.
