Costs & verdict
Everyday costs, plus how reliable and safe it is
Costs, insurance groups, MPG and CO2
We reckon the entry-level Audi TT engine – the 40 TFSI – makes the most sense. It keeps the price and running costs reasonable (officially it'll do up to 42.2mpg and emit 154g/km of CO2), yet is still pretty nippy. The more powerful 45 TFSI won't break the bank either, but if you add quattro four-wheel drive the fuel economy drops and the CO2 emissions rise a bit more.
Then again, it's all relative: next to a V8 Ford Mustang even the TTS is cheap to run considering the pace it delivers. No matter which TT you go for, depreciation is likely to be slightly faster than the Mustang and the Porsche 718 Cayman.
Black Edition mostly adds black styling details, including the wheels, front grille and door mirror casings. Vorsprung trim is very expensive for both the TT and TTS, and only worth a look if you're a real hedonist.

Reliability
Audi as a brand finished close to the middle of the field in the 2021 What Car? Reliability Survey, claiming 18th place out of the 30 manufacturers included. That puts it above Ford and Porsche in the standings, but below BMW.
The TT as a model found much more success in the Coupés, Convertibles and Sports Cars section of our survey, sharing top spot with the Mini Convertible. The Cayman finished in last place (out of eight models included).
