The 2020 Audi R8 Spyder AWD 5.2L 10-cyl gets 16 MPG combined. No one buys this car for its fuel efficiency. Buyers want an exciting, open-top driving experience with a naturally aspirated V10 engine. Fuel economy is, at best, an afterthought, a practical reality for those who can afford the R8’s six-figure price tag.

City and highway performance

The R8 Spyder’s fuel consumption is 13 MPG in the city and 20 MPG on the highway. This difference highlights the engine’s character. Short city trips mean the engine rarely reaches its optimal power band. The stop-and-go nature of urban driving prevents the seven-speed dual-clutch transmission from settling into higher, more efficient gears. On the open road, with consistent speeds and minimal traffic, the R8 can stretch a gallon of premium fuel a bit further, though even 20 MPG is not great.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Audi R8 Spyder AWD 5.2L 10-cyl at $3,600. This is based on driving 15,000 miles per year, with 45% in the city and 55% on the highway, using the national average fuel price. While $3,600 is a considerable sum compared to more efficient vehicles, it rarely deters the R8’s target demographic. They understand that potent performance requires fuel consumption that matches its capabilities.

Real-world expectations

Real-world fuel economy for the R8 Spyder can change significantly based on driving style. Someone who frequently uses the engine’s power will likely see numbers below the EPA estimates.

On the other hand, a more relaxed driving style, focusing on smooth acceleration and consistent highway speeds, might yield results closer to, or even slightly above, the EPA figures. Resisting the urge to push the engine is a challenge for most owners because of the car’s appealing sound and quick response. You can find R8 MPG across all years on our website.

How it compares

The 2020 Audi R8 Spyder is uniquely positioned among high-performance convertibles. The Porsche 911 Turbo S Cabriolet boasts a combined 17 MPG thanks to its turbocharged engine and offers similar performance with slightly better fuel efficiency. The Mercedes-AMG GT C Roadster, with its combined 18 MPG, also gets better fuel economy than the R8.

The allure of the R8 lies in its naturally aspirated V10, becoming increasingly rare and valued for its immediate throttle response and unique sound. The R8’s MPG deficit is acceptable because of its engine.

Tips to maximize efficiency

Outright fuel efficiency isn’t the R8’s strength, but a few techniques can help extract slightly better mileage. Gentle acceleration is helpful. Avoid stomping on the accelerator pedal unless full acceleration is needed. The V10 can move you along very quickly even when gently accelerated.

Take advantage of the R8’s drive select modes. Selecting “Comfort” or “Auto” modes softens throttle response and tells the transmission to upshift sooner, reducing fuel consumption in normal driving.

Ensure your tires are properly inflated. Correct tire pressure reduces rolling resistance, leading to improved fuel economy. Even a slight pressure decrease can negatively impact fuel consumption, handling, and tire wear. Consult the sticker on the driver’s side doorjamb for the recommended pressure.

Minimize idling. Modern engines consume fuel even when stationary. If you anticipate an extended stop, like waiting for someone, turning off the engine can save fuel. It’s a small difference, but it adds up. See all Audi fuel economy data on our site.
