26 MPG combined isn’t exactly amazing fuel economy, but in the 2017 Audi TT Roadster quattro, it’s a reasonable compromise between spirited performance and acceptable running costs. This isn’t basic transportation; it’s a statement, a weekend escape machine engineered for enjoyment. Buyers aren’t prioritizing ultimate efficiency; they’re seeking open-air thrills and the sure-footedness of all-wheel drive, and they understand that comes at a price.

City and highway performance

The EPA estimates of 23 MPG in the city and 30 MPG on the highway reflect the TT Roadster’s duality. In urban environments, the stop-and-go driving reduces fuel economy, as it does on nearly every performance-oriented vehicle. The responsive 2.0L turbocharged four-cylinder engine, while relatively efficient, still requires fuel to deliver its punchy acceleration. On the open road, the TT Roadster fares better. The six-speed automatic transmission allows the engine to settle into a more efficient range, and the aerodynamics, though not optimized for pure efficiency, contribute to reduced fuel consumption at higher speeds. Drivers have reported that the highway figure is attainable with consistent, smooth driving. Aggressive driving, which the TT Roadster readily encourages, will quickly diminish those numbers.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 Audi TT Roadster quattro at $1,700. This figure is based on driving 15,000 miles per year and assumes the average national fuel price. It’s a useful benchmark for comparison, but individual costs will vary based on driving habits and local fuel prices. Someone who commutes daily in heavy traffic will likely exceed this estimate, while a weekend driver may spend less. It is also important to remember that this is an estimate and fuel prices can rise over time. Understanding how this number is calculated provides a solid foundation for determining your potential ownership costs.

Real-world expectations

While the EPA provides standardized estimates, real-world fuel economy often differs. Many TT Roadster owners report achieving figures close to the EPA estimates with careful driving, but this car begs to be driven enthusiastically. The turbocharged engine and sporty suspension encourage drivers to explore the car’s capabilities. Expect that spirited driving will drop fuel economy closer to the low 20s, and sustained high-speed cruising can also reduce efficiency. Tire pressure and vehicle maintenance will have an impact as well. Keep in mind that the quoted EPA figures are a best-case scenario. For more information, see TT MPG across all years.

How it compares

The 2017 Audi TT Roadster quattro is in a competitive segment of sporty convertibles. The BMW Z4 sDrive28i (discontinued after 2016, but still a relevant comparison) achieved ratings of 22 MPG city and 33 MPG highway, making it a slightly more efficient highway cruiser than the TT. The Porsche 718 Boxster, in its base configuration, delivered comparable numbers around 21 MPG city and 28 MPG highway, proving that a performance car can be reasonably thrifty, but it isn’t a priority. On the other hand, the Nissan 370Z Roadster, equipped with a larger V6 engine, falls short with ratings around 17 MPG city and 24 MPG highway. These comparisons illustrate that while the TT Roadster isn’t the absolute thriftiest in its class, it strikes a good balance between performance and fuel consumption. These differences can impact long term costs, which is important for comparison shopping. You can see all Audi fuel economy data for a wider look at the brand.

Tips to maximize efficiency

Take advantage of the Audi Drive Select system. Choosing the “Efficiency” mode optimizes engine and transmission settings for lower fuel consumption. While this mode may dull the throttle response slightly, it can make a noticeable difference in urban driving or on long highway stretches. Don’t be afraid to use it even if you bought the car for spirited driving.

Pay attention to tire pressure. Underinflated tires increase rolling resistance, which leads to higher fuel consumption. Check your tire pressure regularly and ensure it matches the recommended levels listed on the door jamb sticker. Even a small adjustment can improve fuel economy and extend tire life.

Avoid aggressive driving habits. Rapid acceleration and hard braking waste fuel. Anticipate traffic flow and maintain a smooth, consistent speed. The turbocharger is a performance enhancer, but relying on it constantly means you will be using more gas. The “thrills” come with a cost, so it’s best to reserve the fun for special occasions.

Minimize idling. If you’re stopped for more than a minute or two, turn off the engine. Modern engines are designed to restart quickly and efficiently, and idling wastes more fuel than restarting. Plus, this is a convertible, so it’s the perfect time to drop the top and enjoy the breeze rather than running the AC.

Use cruise control on the highway. Maintaining a consistent speed with cruise control minimizes unnecessary acceleration and deceleration, which can improve fuel economy. It will also prevent the need to constantly monitor the speedometer, which becomes important on those long drives where you might be tempted to push the speed limits.
