Self Study Program 221 – Electronic Manual Gearbox

Self Study Program 221 – Electronic Manual Gearbox Design and Function PDF free online

Taking the Lupo as the basis, Volkswagen has developed the world’s first 3 L car that will also go into volume production.

Designing a vehicle which covers 100 km on 3 litres of fuel involved a great deal of detail work.

Factors influencing fuel consumption – such as aerodynamics, rolling resistance, engine concept, gearbox tuning and kerb weight – have been revised systematically.

The goal was achieved by using new technologies, weight-saving materials and new production processes.

However, the driver also plays a key role with regard to fuel economy. A great many drivers are not aware of this fact, though.

The new electronic manual gearbox eliminates gear shift errors. Gear shifts are executed automatically and in such a way as to optimise fuel consumption.

The advantages of an electronic manual gearbox over an automatic gearbox are lower weight and higher efficiency.
