The 2023 Audi TT Roadster 2.0L gets 25 MPG combined, which won’t win any fuel efficiency contests, but frankly, that’s okay. The TT Roadster is about style, open-air fun, and standing out. Fuel economy is a secondary concern for drivers interested in its sharp looks and agile handling.

City and highway performance

The EPA estimates the 2023 Audi TT Roadster gets 23 MPG in the city and 30 MPG on the highway. The city number reflects typical stop-and-go urban driving. The 2.0L turbo engine works harder in these conditions, while the highway figure shows the benefits of the seven-speed S tronic dual-clutch transmission. This transmission allows the engine to run at lower RPMs at higher speeds, improving efficiency. This difference suggests the TT Roadster is fairly efficient for longer drives, especially for those who get out of the city occasionally.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Audi TT Roadster is $1,750. This is based on driving 15,000 miles per year and using national average fuel prices. Keep in mind that changing fuel prices will affect the actual cost. And aggressive driving will also change this estimate, and could increase your annual fuel cost.

Real-world expectations

EPA estimates give a starting point, but real-world fuel economy really depends on driving habits and conditions. Expect the 2.0L turbo engine to perform closer to the EPA estimates with smooth acceleration and consistent speeds. But frequent hard acceleration to enjoy the car’s power, or long periods of idling, will likely reduce those numbers. Owners on forums report that the real-world combined average generally ranges from 22 to 27 MPG.

How it compares

The BMW Z4 sDrive30i, a direct competitor, gets a slightly better EPA combined rating of 28 MPG. Its highway figure is a similar 31 MPG, while its city MPG is 25 MPG. The Porsche 718 Boxster, although in a different performance class, offers a similar open-top driving experience, but gets around 24 MPG combined with its base 2.0L engine. Comparing the TT Roadster to something like a Mazda MX-5 Miata (29 MPG combined) shows the trade-off between maximizing fuel efficiency and the Audi’s premium features and powerful turbocharged engine. Buyers reviewing all Audi fuel economy data often balance these performance and luxury aspects against the slightly lower MPG.

Tips to maximize efficiency

The TT Roadster’s S tronic transmission includes an “efficiency” mode. Select this setting for relaxed daily driving. The transmission will shift at lower RPMs and encourage a smoother driving style, improving fuel consumption without significantly changing the driving experience. If you care about saving fuel, this is an easy way to spend less money while driving in the city.

Make sure your tires are inflated to the correct pressure. Underinflated tires increase rolling resistance. This makes the engine work harder which wastes gas. Check your tire pressure regularly, especially when the temperature changes, and keep the pressure at the level recommended on the tire placard.

Avoid idling unnecessarily. Letting the engine run while stopped for a long time wastes gas. If you’re stopped for more than a minute or two, turn off the engine. The Audi’s quick start-up system means restarting is easy and won’t really affect battery life.

Plan your trips and avoid rush hour if possible. Stop-and-go traffic really hurts fuel economy. By taking less busy routes or traveling when there is less traffic, you can keep a more consistent speed and increase your MPG. See TT MPG across all years for more information on the TT model range.
