MPG, running costs & CO2 Rating

4.0 out of 5

The TT Roadster is a sporty car that feels relatively exotic, so it’s a pleasant surprise to find it's relatively cheap to run. This does, of course, depend on exactly which model you choose, but overall the TT performs well in this category.

Audi TT Roadster MPG and CO2

The entry-level 195bhp 2.0-litre 40 TFSI petrol is only available with front-wheel drive and a seven-speed dual-clutch S tronic gearbox. It returns up to 39.8mpg (WLTP), with CO2 emissions of 143g/km, resulting in a high Benefit-in-Kind (BiK) band. If you want to drive your TT in the most efficient manner possible, you can use a special setting built into the five-mode Drive Select system that sacrifices some performance for better fuel economy. 

Fuel economy drops to around 34mpg if you choose the 2.0-litre 45 TFSI petrol engine with quattro in S Line, Black Edition or Vorsprung trim levels. The combination of larger alloy wheels and all-wheel-drive increases CO2 emissions to 166g/km, placing the TT in the higher BiK bracket for company-car drivers.

Insurance group

The 2.0-litre TFSI petrol TT Roadster falls into insurance groups 37 to 43, depending on the exact specification and gearbox you choose.


Like many current VW Group vehicles, the Audi TT can be run on a fixed or flexible service schedule. Audi recommends the fixed schedule (which requires a dealer visit every year or 9,000 miles) for drivers that cover a low annual mileage or mostly do short journeys.

The flexible service schedule uses sensors on the car to detect when it needs attention and is best suited to drivers who mostly do long-distance motorway trips. It can extend the time between visits up to a maximum of 19,000 miles or two years. Exact service costs for Audis up to three years old depend on your local dealer.


Audi offers a three-year/60,000-mile warranty on all its new cars. This is fairly standard for the industry, although some manufacturers (such as BMW) offer three-year warranties with unlimited mileage, and there are others (like Hyundai and Kia) that offer five or even seven-year warranties.
