With a conventional mechanical transmission gear shifts require an interruption of the connection between engine and gearbox which not only harms the comfort and the performances of the vehicle, but also represents a loss of kinetic energy. A shift under load, without disruption of the torque transmission is thus desirable. This is commonly performed by automatic transmissions composed of a hydrodynamic torque converter associated to planetary gear trains. But these automatic transmissions are complex, expensive and their efficiency remains lower than that of manual mechanical gearboxes. The simple and effective twin clutch concept invented by a brilliant French engineer before WW II has at last been developed and its mass production launched by VW and Audi. The competitors certainly do not intend to be left behind…
