Audi Q7 lightweight
Friedrich-Oskar Winter, Audi Q7 rear axle development.
The new five-link rear axle is 40 kg (88.2 lb) lighter compared with the previous model, which is particularly noticeable in terms of improved comfort and agility. This result was made possible by an intelligent material mix featuring high-strength steels for the subframe and links, and the targeted use of aluminum.
Combined fuel consumption in l/100 km: 7 – 6,5;
Combined CO2-emissions in g/km: 181 – 172
(Figures on the fuel consumption and the CO2-emissions vary in case of given ranges depending on the used combination of wheels/tires.)
Fuel consumption and CO2 emissions data as well as the efficiency classes are dependent on the choice of wheels and tyres.
