drivetrains
The Siemens and Michelin videos here could equally well have gone into the Tyres & Wheels section; indeed you will find there more information on the Michelin Hy-Light Active Wheel Motor EV concept. Putting it all together blurs the distinction between tyres and wheels ad drivetrains!
Siemens VDO engineers are working on plans to integrate the drivetrain, steering, shock absorbers and brakes directly into the wheels of future cars. This concept, called eCorner, is the basis for the ecological "Drive-by-Wire" automobiles, which will become a common sight on roads in 15 years. eCorner replaces the conventional wheel suspension with hydraulic shock absorbers, mechanical steering, hydraulic brakes and, above all, conventional internal combustion engines. For car owners, eCorner translates into improved fuel mileage, more safety and greater convenience. eCorner provides designers with all new freedom to create future cars with an electric drivetrain and electronic control.

A breakthrough in the design of Toroidal CVT used to create CVT and IVT transmissions. These transmissions have been used by Tata Pixel Torotrak, NSK, Nissan, and CVTCorp . The Ultimate Transmissions design uses Double Rollers in place of Single Rollers and improves the efficiency and reduces the size and complexity of the CVT. This type of drive is used in KERS energy saving systems used by Volvo and Jaguar. May 2011
