Global market leader since 1985
More than 50% of heavy duty trucks produced in Europe are equipped with AMT systems
Focus on fuel efficiency will push higher penetration in all markets
Here are some specifics on two applications that will drive new sales for us -- Truck Automated Transmissions and Air Disc Brakes. Both of these are opportunities where we have a competitive advantage
Innovation Mitigates Price Pressure
Leaders Define the Product / System - Others Must Pay to Follow
Migration Path : Manual>>Clutch Servo>>Automated
Truck Automated Transmissions
There is a significant market opportunity here. 50% of the Heavy Trucks delivered in Europe will have automated transmissions by The US will follow after that repeating the pattern of ABS
We have partnerships with Volvo, DaimlerChrysler and ZF in Europe, and these will extend globally as familiarity with the technology increases. Volvo will include our technology on its flagship truck [FH12] – it’s called the “I-Shift” – i stands for intelligent
And, we are on track to deliver the sales projections we gave in February this year. In fact, if anything we may have been a little conservative.
Sales in 2003 were ~$ 70M, and we expect sales of ~ $155M in 2008
