Audi Q7 lightweight
Alexander Steigerwald, Audi Q7 front axle development.
Thanks to the new five-link front axle and systematic lightweight construction, 27 kilograms (59.5 lb) of weight have been shaved from the front axle alone compared with the previous model. All major components are made of aluminum. The forged aluminum pivot bearing alone saved nearly 7 kilograms (15.4 lb).
Combined fuel consumption in l/100 km: 6.4 – 5.5 (36.8 – 42.8 US mpg)
Combined CO2 emissions in g/km: 168 – 144 (270.4 – 231.7 g/mi)
(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.
