MPG, running costs & CO2 Rating

4.0 out of 5

The most basic Audi TT costs more than the model it replaces, but it’s also a better-equipped, faster and more economical car. All models should hold their value well, as the Audi badge continues to be sought-after on the secondhand market.

Audi TT MPG & CO2

There isn't currently a diesel in the TT range, which might knock its popularity with long-distance drivers, but for a sports coupe its petrol engines are quite efficient.

This is partly thanks to Audi's clever Economy Drive Select system, allowing you to tweak various settings from behind the wheel, optimising the engine and gearbox for maximum fuel economy. What's more, if you go for the S tronic automatic gearbox, the car will automatically 'coast' in neutral to save fuel as soon as you lift your foot off the accelerator.

The entry-level 40 TFSI petrol engine manages up to 40.9mpg, with CO2 emissions of 155-156g/km. This is the model you should go for if you mainly make shorter trips.

The other two 2.0-litre TFSI petrol variants have 242bhp (45 TFSI) and, in the high-performance TTS model, 302bhp. Paired with a manual gearbox, the former returns up to 39.8mpg and emits 161-162g/km of CO2 – opt for the S tronic automatic and four-wheel drive and these figures change to 35.3mpg and 181-182g/km. This places it in the highest Benefit-in-kind (BiK) bands for company-car drivers. The TTS manages a figure of up to 34.9-35.3mpg, but you can expect this figure to be very tricky to achieve in real life, unless you're on a long motorway cruise.

All Audi TT models will attract road tax of £150 a year after the first year’s CO2-weighted payment, which is usually included in the on-the-road price. Those with a list price (including options) of more than £40,000 are liable for an additional surcharge of £325 a year in years two to six of ownership, bringing the annual bill to £475 during that period.


The 40 TFSI 2.0-litre petrol TT sits in insurance group 35, while the 45 TFSI 2.0-litre petrol quattro model is in group 39.


Audi offers a three-year/60,000-mile warranty on the TT. The Porsche 718 Cayman and BMW 2 Series offer slightly better three-year/unlimited-mileage warranties, so bear this in mind if you’re a high-mileage driver.


As with all other Audis, the TT benefits from fixed-price servicing deals called Audi Complete, which can include services, servicing and maintenance, or both of the above, and replacement tyres.
