1998 - 2002:
How will BMW Group continue tobe successful in times of climatechange, tougher fuel economylegislation, skyrocketing oil pricesand a growing environmental awareness in the broad public?
BMW EfficientDynamics.How it began.

Slide 3
Historicaly, better efficiency leads to lower performance.(Still true for many brands).
In some cases, efficiencyimprovements are possible whileperformance doesn‘t suffer. (Should be state of the art today).
In very rare cases a manufactureris able to improve efficiency andperformance at the same time.

Application: Power Generation
for Deep Space Exploration
Direct conversion of
waste heat into electricity ?
• Direct conversion of thermal into
electrical energy.
• Technology transfer from deep space
exploration to the automotive industry.
• Thermoelectricity has been applied
for deep space exploration for several
decades.
