Audi Q7 lightweight
Xaver Hackl, Audi Q7 cooling fan module development.
The components of the cooling system are 8.7 kilograms (19.2 lb) lighter compared with the previous version. With this cooling fan module, for example, the weight was reduced by 3.5 kilograms (7.7 lb).
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.
