Audi Q7 lightweight
Boguslaw Jan Nowak, Audi Q7 exhaust system development.
The completely new Q7 exhaust system is 19 kilograms (41.9 lb) lighter than the previous version.
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.
