When I buy a car, the price is theabsolutely decisive criterion

I couldn‘t imagine life without a car

When I buy a new car, the fuel consumption is very important for me, even if it means

spendingmore money for this lower fuel consumption

A car‘s eco-friendliness isof the greatest impotence for me

A car has to be at the cutting edge of technology

For me a car is simply a functional object

Cars are a major problem for the environment

For me a car is of particular interest if it is a very innovative and advanced model

I can get really enthusiastic about cars

• Stringent emission legislation (orientation on gasoline engine)

• High requirements to OBD

• Various fuel quality with large dispersions

• Intensified climatic edge conditions

Robust, sustainable solutions are required

New technologies are needed

Advantages

- High NOx-efficiency up to high engine loads

- Long term emission stability

-No increase in fuel consumption

Challenging requirements

- UREA infrastructure common efforts necessary necessary

- OBD

SCR systems are available for trucks in Europe and Japan

BMW judgement: long term solution for diesel engines


BMW Diesel.Conclusion.

• Portion of BMW Diesel passenger cars in Europe has significantly increased within the last decade

• BMW Diesel philosophy is “efficient dynamics”

• BMW at leading edge of diesel technology

• BMW target for US is to fulfil 50 state legislations

• Technology concept for BIN 5 defined, but still challenging

• Compromisses to Diesel necessary (i.e. phase-in`s)

BMW Diesels: dynamic, efficient and clean


Thank you very much for your attention!
