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 29 - 33 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.

Few high performance sports cars are cheap to run, but the TT RS isn’t as expensive as you’d think for a car that can cover 0-62mph in just 4.6 seconds. Average fuel economy is a respectable 31mpg while emissions of 214g/km of CO2 (221g/km in the Roadster) means it escapes the highest road tax bracket. Audi servicing isn’t especially cheap though and neither are parts, but you can expect impressive customer care from dealers.

The 2.5 TFSI engine is fairly efficient given its 340bhp output, although compared to a family hatchback it’s a poor performer. It emits 214g/km of CO2 and averages 31mpg while the Roadster emits 221g/km and returns 30mpg – figures on par with other two-seater sports cars.

Audi has an impressive reputation for reliability and the TT has proved extremely reliable. The 2.5 TFSI engine in the RS hasn’t been used before, but it should prove just as robust as other Audi powerplants.
