CO2 information Vehicle technology

“e” for efficiency. The Audi efficiency models, namely the Audi A3 1.9 TDI e, Audi A4 1.9 TDI e and 2.0 TFSI e, are clean best-sellers. Even today, the Audi A3 1.9 TDI e undercuts the emission threshold aspired to by law. Its CO2 emission value is a mere 119 g/km. In the saloon and Avant variants, the A4 1.9 TDI e also combines high efficiency with powerful propulsion. The saloon version emits as little as 137 g CO2 / km with an average fuel consumption of 5.2 l diesel. In spite of this, it generates 115 bhp and sprints in 11.2 seconds from 0 to 100 km/h.

TDI and TFSI are the names given to the established core fields of expertise for engine efficiency made by Audi. Highly efficient turbodiesel direct injection (TDI) produces a clear reduction in CO2 emissions. FSI and TFSI exploit the advantages of direct injection in petrol engines. Both innovations produce higher performance, coupled with around 15 percent less fuel consumption.

The innovative Audi Space Frame® design incorporates our very latest body technology. The bodyshell of the new Audi TT, for example, weighs in at as little as 206 kg. The saving in weight of up to 100 kg compared with its predecessor lowers fuel consumption by 16 percent. As regards the aerodynamics, Audi continues its long tradition. With a drag coefficient of 0.29, the Audi 100 presented in 1982 came to be regarded for many years as the measure of all things and went down in company history as having the world’s best drag coefficient.
