Buyers of the 2023 Audi R8 Spyder quattro 5.2L 10-cyl will likely gloss over 15 MPG combined on their way to enjoying one of the last naturally aspirated V10 engines available in a road car. This isn’t a pragmatic purchase meant for maximizing commuting efficiency; it’s a statement, a visceral experience, and a demonstration of automotive passion. The target demographic isn’t prioritizing fuel savings, but rather the thrill of open-top motoring paired with the unmistakable roar of a high-revving Italian-derived engine.

City and highway performance

The EPA estimates for the R8 Spyder break down to 13 MPG in the city and 18 MPG on the highway. The city figure reflects stop-and-go driving where the engine is less efficient, constantly accelerating and decelerating. The 18 MPG highway rating suggests that when cruising at a steady speed, the R8 can achieve marginally better mileage. However, anyone expecting Prius-like economy on long journeys in this vehicle misunderstands its purpose. The AM-S7 automatic transmission prioritizes rapid shifts and driver engagement over optimizing fuel consumption. Expect to visit the gas station frequently, particularly if you are enjoying the prodigious power and soundtrack the V10 delivers.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2023 Audi R8 Spyder is estimated at $3,850. This figure is based on driving 15,000 miles per year and using national average fuel prices. Remember that premium fuel is unequivocally required, which will impact the actual cost. This expense is a drop in the bucket for most R8 owners, who are more concerned with the cost of servicing, insurance, and potential depreciation than fuel costs.

Real-world expectations

The EPA estimates provide a baseline, but real-world fuel economy will vary significantly depending on driving style and conditions. If you spend most of your time in heavy traffic or frequently indulge in spirited driving, expect to see numbers closer to the city estimate, or even lower. Conversely, if you primarily use the R8 for longer highway cruises at moderate speeds, you might approach the 18 MPG highway rating. The temptation to unleash the V10 is simply too great.

How it compares

Compared to other high-performance convertibles, the R8’s fuel economy is fairly typical. The Porsche 911 Turbo S Cabriolet, for instance, gets an EPA-estimated 15 MPG city and 20 MPG highway. The McLaren 720S Spider, though capable of exceeding 20 MPG on the highway in the right hands, also has a thirstier city rating. A Chevrolet Corvette Z06 Convertible offers a slightly superior combined rating of 17 MPG, but lacks both the Audi’s all-wheel drive grip and its exotic European flair. Ultimately, these differences are unlikely to sway the decision-making process for buyers in this segment. They are purchasing performance and exclusivity, accepting the inevitable implications for fuel consumption. You can compare R8 MPG across all years to see how this model year stacks up.

Tips to maximize efficiency

While fuel efficiency is likely not a primary concern, there are still a few strategies to minimize fuel consumption in your R8 Spyder. Avoid aggressive acceleration and braking. The V10 is responsive, but gentle inputs will conserve fuel, even if it’s just a marginal amount.

Ensure your tires are properly inflated, as underinflated tires increase rolling resistance and reduce fuel economy. Check the tire pressure regularly and adjust as needed.

Minimize idling. The R8’s engine is not particularly efficient at idle, so avoid letting it run unnecessarily. Turn off the engine if you’re stopped for more than a minute or two.

Consider using the “comfort” driving mode when cruising. While it might slightly dampen the throttle response, it can help optimize fuel efficiency in less demanding driving situations. Even in this mode, any sudden demand for power will instantly awaken the V10.
