16 MPG combined is what you’ll get when you join the naturally-aspirated, V10 supercar club. The 2021 Audi R8 5.2L isn’t bought to save gas. It’s bought for the visceral experience, the immediate throttle response, and the glorious sound that only a high-revving, ten-cylinder engine can make. Fuel economy is a distant afterthought ,if it’s even a conscious thought, for those drawn to the R8’s unique blend of performance and everyday usability.

City and highway performance

The EPA estimates the 2021 Audi R8’s fuel consumption at 13 MPG in the city and 20 MPG on the highway. The city figure reflects the stop-and-go nature of urban driving, where the R8’s engine spends considerable time idling or accelerating from a standstill. The highway number, while better, is still relatively low compared to more mainstream vehicles. This is because of the engine’s displacement and the aerodynamic profile, both optimized for high-speed performance rather than outright efficiency.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Audi R8 at $3,600. This is based on driving 15,000 miles per year and using national average fuel prices. It’s important to understand that this is just an estimate, and the actual cost may vary depending on driving habits, local fuel prices, and the type of fuel used. Owners who frequently drive aggressively or primarily use the R8 for short trips will likely exceed this estimate.

Real-world expectations

Official EPA numbers provide a useful baseline, but real-world fuel economy for the 2021 Audi R8 is highly dependent on driving style. Owners who prioritize fuel conservation during highway cruising can likely get numbers closer to the 20 MPG mark, but heavy use of the throttle will quickly diminish those gains. In urban environments, especially in congested traffic, the R8’s fuel consumption can easily drop below the 13 MPG estimate. Some owners report averages in the single digits during track days or extended periods of aggressive driving. The R8’s fuel economy reflects its performance-oriented nature, rewarding drivers with thrilling acceleration and a captivating exhaust note at the expense of efficiency. Before purchasing, consumers should look at all Audi fuel economy data.

How it compares

The 2021 Audi R8’s fuel economy is similar to other supercars. The Lamborghini Huracan, which shares its engine platform with the R8, achieves similar figures. The Huracan EVO is rated by the EPA at 13 MPG city, 18 MPG highway, and 15 MPG combined. A Porsche 911 Turbo S, with its advanced turbocharging technology, achieves a slightly better 15 MPG city, 20 MPG highway, and 17 MPG combined. More conventional sports cars like the Chevrolet Corvette C8 get significantly better mileage, achieving 16 MPG city, 24 MPG highway, and 19 MPG combined, but these cars lack the prestige and rarity of the Audi R8. These comparisons matter because buyers may be cross-shopping or looking at trade-in options. See R8 MPG across all years for more information.

Tips to maximize efficiency

Using engine braking can reduce fuel consumption, particularly in stop-and-go traffic. Downshift early when approaching red lights or slowing down. Let the engine decelerate the car rather than relying solely on the brakes. This minimizes fuel injection during deceleration and can improve overall fuel efficiency in city driving.

While tempting, resist using the R8’s launch control feature constantly. Engaging launch control puts strain on the engine and transmission, and it increases fuel consumption. Save this feature for special occasions or track days. Avoid frequent use in everyday driving.

Make sure your tires are properly inflated to the recommended pressure. Underinflated tires increase rolling resistance, forcing the engine to work harder and use more gas. Check your tire pressure regularly and adjust as needed, especially before long trips.

Keep idling time to a minimum. A running engine uses fuel even when the car is stationary. If you anticipate being stopped for more than a minute or two, turn off the engine to save fuel. This can save gas over time.
