The well-known car companies Ford and Fiat are about to present a new transmission for cars that can replace the traditional speed change, both manual and automatic.

The new transmission is based on a system used in automatic mopeds. It consists of two discs. One of them modifies its diameter according to the centrifugal force, modifying practically the final ratio of demultiplication from zero to infinity. The transmission is carried out by a steel plate strap. This tape measures 1.6 l of displacement and 12.5 kg. Valid for motors up to m.

The most obvious advantage of this transmission system is the simplicity and the need for fewer parts. In addition, the consumption of this transmission is similar to that of manual transmission. Smoother driving. However, car performance slows slightly.
