Fuel economy

A more stringent standard for fuel economy (WLTP) was introduced from September 2017, and this model was not required to undergo that test. Its fuel economy measured under the previous test system was 26 - 34 mpg. However these figures are less likely to be achievable in real world driving and so should never be compared to another car's mpg which was measured under the newer, more realistic WLTP system.

You won’t buy a Mk1 Audi TT as a money-saving exercise. Despite this, fuel economy isn’t too bad (all versions can manage close to 30mpg if you’re careful) and the car is now old enough to qualify for classic car insurance, which can save you a good chunk of change. Shop around to find a good deal.

Residual values are on the up, too, providing you’re prepared to look after the car well. Audi servicing is renowned for being expensive at the main dealer – however, we recommend using an independent specialist instead these days.

The TT isn’t the most ecological car, though. With an average of 224g/km CO2 across the model line-up, its emissions are a little high for a sports coupe. It’s worth noting that the line-up does not feature any diesel models, which typically produce less carbon dioxide than petrol engines with similar power outputs.

Audi materials are of the highest quality and the TT has been engineered to be used every day so, if it’s been properly serviced, even high mileages aren’t a problem.
