What's good
In the UK, the new Audi Q7 will initially be powered by a 272 PS V6 TDI engine. This complies with the Euro 6 emissions standard and its CO2 emissions have been reduced by as much as 50 grams per km.
Where it falls short
The new Audi Q7 comes standard with 19-inch wheels. Audi and quattro GmbH offer a large number of additional wheels in sizes up to 21 inches as options. Large, vented brake discs bring the SUV safely to a stop. They are gripped up front by aluminium six-piston calipers. The electromechanical parking brake, updated with convenient hill hold and startup functions, acts on the rear wheels.
Use the failure ranking as a pre-test checklist or a haggling lever. Treat the headline pass rate as a fleet-wide trend, not a guarantee on any individual car.
If you own a Q7 Sln Blk ED 50tdi Mhev Qto A and your last MOT looked nothing like the ranked failures above, that's normal — individual cars vary widely. The ranking shows the patterns testers flag most often across the country.
