At 26 MPG combined, the 2015 Audi TT Coupe quattro 2.0L isn’t designed for hypermiling. It’s a stylish sports coupe, not a dedicated fuel sipper. That said, this figure is a reasonable trade-off for the performance and all-weather grip that the TT offers, a key consideration for buyers who prioritize driving enjoyment and a distinctive design over ultimate fuel efficiency.

City and highway performance

The TT’s EPA ratings break down to 22 MPG in the city and 31 MPG on the highway. The city number reflects stop-and-go traffic, where the engine spends more time idling and accelerating. The highway figure represents its potential when cruising at a steady speed. The 2.0L turbocharged engine, while relatively small, needs to work a bit harder to haul the TT’s weight around in city conditions.

On the open road, the aerodynamics and well-chosen gear ratios allow it to stretch a gallon of fuel further. The fuel economy differences between the city and highway ratings show that the TT is much more efficient when it can cruise on interstate roads. As a sports car with all-wheel drive, the Audi TT wouldn’t compete with a compact hatchback in city-driving scenarios. For access all Audi fuel economy data.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2015 Audi TT Coupe quattro 2.0L at $2,250. This calculation is based on driving 15,000 miles per year and using the EPA’s estimate of prevailing fuel prices. This is just an estimate and your actual fuel costs will vary depending on your driving habits, the type of fuel you use, and local fuel prices. Someone driving predominantly in the city and with a heavy foot might exceed this figure, while someone who does mostly highway driving at moderate speeds could potentially spend less.

The $2,250 figure provides a useful baseline for comparing the TT’s fuel costs with other vehicles in its class.

Real-world expectations

While the EPA ratings provide a standardized comparison, real-world fuel economy often differs. Drivers who frequently use the TT’s available performance, accelerating hard and enjoying its sporty handling, should expect figures closer to the city rating, or even slightly below that. Those who prioritize less gas and drive with a more conservative style, particularly on the highway, could realistically achieve figures at or even slightly above the EPA’s 31 MPG highway estimate. As a general rule, premium fuel is recommended for achieving the best performance and fuel economy from the TT’s engine.

How it compares

Compared to other sporty coupes of the era, the 2015 Audi TT’s fuel economy is reasonable, but not class-leading. Consider the BMW 228i Coupe from the same year, which achieves a slightly better 28 MPG combined in RWD configuration according to the EPA. On the other hand, the Nissan 370Z, a more powerful but less refined sports car, only manages around 22 MPG combined. The Subaru BRZ, known for its lightweight design and rear-wheel drive, offers a slightly better 25 MPG combined, which is about the same as TT MPG across all years.

These comparisons highlight the compromises inherent in the sports coupe segment, where performance, features, and fuel economy are all balanced differently across various models.

Tips to maximize efficiency

Avoid aggressive acceleration and braking. The TT’s turbocharged engine is responsive, but heavy use of the throttle will significantly reduce fuel economy. Gentle acceleration and anticipating traffic conditions can make a noticeable difference over time.

Use cruise control on the highway to maintain a consistent speed and minimize unnecessary acceleration and deceleration, especially on longer trips.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which leads to reduced fuel economy. Check your tire pressure regularly and inflate them to the manufacturer’s recommended specifications, found on the tire placard inside the driver’s side door. This simple step can improve your MPG and extend the life of your tires.

Reduce unnecessary weight. Carrying excess cargo in the trunk or back seat adds weight to the vehicle, which reduces fuel economy. Remove any items you don’t need to lighten the load and improve your MPG. A lighter vehicle also benefits from better handling.

Consider using the Audi Drive Select system. If equipped, choose the “Efficiency” mode to optimize engine and transmission settings for fuel economy. Also try running a fuel injection cleaner periodically, particularly if you notice a drop in performance or fuel economy. A clean fuel system helps your TT run efficiently.
