Audi Q7 lightweight
Andreas Ottinger, Audi Q7 aluminum spring link development.
The new Q7 extruded aluminum spring links are the first on the market and in this segment. This alone enabled a reduction of nearly 4 kilograms (3.7 kg) [8.8 lb (8.2 lb)] of weight.
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.
