Maybe it’s the fact that in the time you read this, a Dual Clutch Transmission could switch gears 40,000 times. Perhaps it’s the fact that DCTs appeal to more buyers by combining impressive fuel-economy, the smooth ride of an automatic and the speed of a manual. It could be the fact that leading clutch suppliers estimate they’ll quadruple DCT sales by 2014. Or maybe it’s the fact that by 2015, 10% of all passenger cars will have them. DCTFACTS.COM gives you endless reasons to believe that DCTs are the future generation DCTFACTS.COM of transmissions. And the more you know about them, the further ahead you’ll get.

Innovative solutions to improve quality of life. As an international leader in technology and services, Bosch is com- mitted to improving quality of life. That is what Bosch employs 283,500 people to do, why it invests some 3.8 billion euros annually in research and development, and why it applies for over 3,800 patents per year. The resulting innovative Bosch products and solutions have one thing in common: they make people’s lives a little better each day.
