25 MPG combined may not be the biggest selling point for the 2021 Audi TTS Coupe, but it’s also not a dealbreaker for drivers who prioritize sharp handling, distinctive styling, and quick acceleration over getting the best gas mileage. This isn’t a car purchased only for commuting; it’s a statement, a weekend getaway car, and a source of daily driver satisfaction in a compact, sporty package. The TTS buyer knows there are more economical choices, but they’ve traded a few MPGs for adrenaline and exclusivity.

City and highway performance

The EPA estimates provide data: 23 MPG in the city and 29 MPG on the highway. The city figure reflects stop-and-go driving, where the TTS’s eagerness to accelerate from every traffic light is likely to be indulged. However, the highway number is more respectable. The 2.0L turbocharged four-cylinder engine, with a seven-speed S tronic dual-clutch transmission, cruises comfortably, rewarding a light foot with near-30 MPG efficiency. The readily available torque also means less downshifting to maintain speed on inclines, which contributes to better highway fuel consumption. Sport mode invites more frequent gear changes and higher revs, which will decrease MPG, but in its standard setting, it balances performance and efficiency well.

Annual fuel cost

The EPA estimates the annual fuel cost is $2,300 for the 2021 Audi TTS Coupe. This is based on driving 15,000 miles per year and national average fuel prices. Premium fuel is recommended to unlock the engine’s full potential, so you’ll be paying more at the pump than drivers of vehicles that use regular unleaded. This cost can change based on your driving, local fuel prices, and the time of year. Aggressive driving, colder temperatures, and poorly maintained tires can all decrease fuel economy and increase your annual fuel expenditure.

Real-world expectations

While the EPA estimates provide a standardized benchmark, real-world fuel economy can vary. Drivers who spend most of their time in congested city streets are likely to see numbers close to the low end of the EPA range, possibly even below 23 MPG if they accelerate hard. However, those who primarily use the TTS for highway cruising could realistically achieve or exceed 29 MPG, especially if they maintain a consistent speed and avoid excessive acceleration. Ultimately, the 2.0L turbo is responsive to driving style. If you’d like further MPG data about all things Audi, you can check out all Audi fuel economy data here at FuelEconomyHub.com.

How it compares

Compared to other sporty coupes, the 2021 Audi TTS is in the middle of the pack. The BMW 230i Coupe, for example, achieves a slightly better 28 MPG combined, while still offering engaging driving. The Toyota GR Supra, with its more powerful engine, gets a respectable 25 MPG combined, matching the TTS despite its performance advantage. On the other hand, the Nissan Z, with its twin-turbo V6 can only muster 22 MPG combined. These comparisons suggest that the TTS buyer accepts a moderate compromise in fuel economy to get the unique styling, refined interior, and all-wheel-drive capability that the Audi offers. They’re not necessarily seeking the absolute best MPG, but rather a balanced package of performance, luxury, and style.

Tips to maximize efficiency

Use the Audi Drive Select system. The “Efficiency” mode optimizes vehicle settings, including throttle response and transmission programming, to save fuel. While it might reduce the TTS’s sporty feel, it can noticeably improve gas mileage on longer trips.

Check your tire pressure often. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Maintaining the recommended tire pressure ensures the best fuel efficiency and extends tire life.

Remove unnecessary weight. Extra cargo in the trunk adds weight, which hurts fuel economy. Remove any unnecessary items to reduce the load on the engine and improve MPG.

Anticipate traffic flow and avoid aggressive acceleration and braking. Smooth, consistent driving habits are key to maximizing fuel efficiency. By anticipating stops and maintaining a steady speed, you can minimize fuel consumption.

Avoid shorter trips which do not fully warm up the engine. Cold starts use lots of fuel. The engine needs to reach full operating temperature to run optimally, so combine errands into a single trip when possible.
