The 2018 Audi TTS Coupe 2.0L’s 25 MPG combined might not be record-setting, but it’s acceptable for a sharply styled, turbocharged performance coupe with all-wheel drive. People buy a TTS for its design, handling, and punchy engine. The fuel bill is often a secondary concern.

City and highway performance

The EPA estimates for the 2018 TTS Coupe are 23 MPG in the city and 27 MPG on the highway. This difference reflects how different driving conditions affect fuel consumption. In urban settings, stop-and-go driving makes the engine work harder, reducing the efficiency gains from the six-speed dual-clutch automatic transmission. The TTS achieves better efficiency cruising on the open road. The transmission keeps the engine in its most efficient range. However, many TTS drivers will likely see real-world highway numbers closer to the city figure because of their driving habits.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2018 Audi TTS Coupe is approximately $2,100. This is based on driving 15,000 miles per year, with a mix of city and highway driving, using national average fuel prices. Premium fuel is recommended for optimal performance and fuel economy, so that $2,100 figure could increase if fuel prices rise.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy varies depending on driving habits, traffic, and even the weather. Expect figures slightly below the EPA estimates with frequent spirited driving or time spent in heavy traffic. Smooth highway driving may yield slightly better results. Owners reporting their numbers to fuel tracking websites often see a range between 22-28 MPG combined, highlighting the impact of individual driving styles.

How it compares

The Audi TTS occupies an interesting position compared to its competitors. A BMW M240i xDrive Coupe, another all-wheel-drive performance coupe, delivers a similar 25 MPG Combined, yet offers more power from its inline-six engine. The Porsche 718 Cayman, a mid-engined sports car, achieves around 24 MPG combined in its base form, but has a higher price. The Nissan Z, more affordable than the Audi, achieves 22 MPG combined. The TTS offers a blend of style, performance, and all-weather capability, with fuel economy that neither excels nor disappoints within its class. Be sure to check TTS MPG across all years to see trends for yourself.

Tips to maximize efficiency

Use the Audi Drive Select system, especially the “Efficiency” mode, which optimizes engine and transmission settings for fuel conservation. This mode reduces throttle response and encourages earlier upshifts, helping you get more miles per gallon during commutes. It’s useful in stop-and-go traffic where you do not need to accelerate quickly.

Make sure your tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly and maintain the recommended levels on the door jamb sticker. This can improve your fuel economy.

Reduce unnecessary weight. Extra cargo adds to the weight of the vehicle, impacting fuel efficiency. Remove items you don’t need regularly to lighten the load and improve your MPG.

Anticipate traffic flow and avoid aggressive acceleration and braking. Smooth inputs are key to maximizing fuel economy. Look ahead, maintain a safe following distance, and coast whenever possible to minimize unnecessary fuel consumption. The Audi TTS rewards smooth driving with good efficiency.

Use cruise control on the highway. Cruise control helps maintain a consistent speed, reducing variations in throttle input and minimizing fuel waste. This is effective on long, flat stretches of road. Be mindful of changing traffic conditions and disengage cruise control when necessary to maintain safety. Always check all Audi fuel economy data to be aware of trends.
