Audi TT Roadster convertible - MPG, running costs & CO2
All models of the Audi TT Roadster are reasonably cheap to run
The TT Roadster is a sporty car that feels relatively exotic, so it’s a pleasant surprise to find that it's relatively cheap to run. While running costs used to depend on which version you went for, the TT Roadster is now only available with the 195bhp 40 TFSI petrol engine, which was the most efficient engine option anyway.
Audi TT Roadster MPG and CO2
While the standard TT Coupe is still offered with a few petrol engine options, the sole option for the Roadster is now the 195bhp 2.0-litre 40 TFSI petrol 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 dropped to around 34mpg in the now-discontinued 2.0-litre 45 TFSI petrol engine with quattro and CO2 emissions increased to 166g/km, so it won’t be missed by buyers after the most economical option.
As a desirable sports car, it comes as no surprise that the 2.0-litre TFSI petrol TT Roadster falls into insurance groups 39 out of 50, so it won’t be cheap to insure. The BMW Z4 could prove cheaper to insure, with the entry-level sDrive20i falling into groups 30-31, although the TT is still cheaper to insure than the Porsche Boxster, which starts from group 46. For a sports car with lower running costs, you’d be better off with the Mazda MX-5, which starts from insurance group 25, although it’s not really in the same league in terms of premium feel, power or desirability.
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.
