15 MPG combined isn’t going to win any lower fuel costs awards, but it’s frankly irrelevant to the buyer of the 2023 Audi R8 Coupe quattro 5.2L 10-cyl. This isn’t a commuter car; it’s a visceral, operatic, mid-engine supercar. Buyers seeking economy shop elsewhere. This R8 represents a specific breed of performance machine, and its thirst for premium fuel is simply part of the ownership experience. Performance is the priority, not practicality, and the glorious sound emanating from those tailpipes more than compensates for frequent trips to the gas station. For those keeping track, it’s the price of admission into an exclusive club.

City and highway performance

The EPA estimates for the R8 stand at 13 MPG in the city and 18 MPG on the highway. These figures reflect the inherent nature of a high-revving, naturally aspirated V10 engine paired with a seven-speed automatic transmission (AM-S7) that prioritizes rapid shifts. Stop-and-go city driving is where the R8 suffers most. The engine never really gets into its sweet spot, and the start-stop system works overtime. Highway cruising is marginally better, but even there, the temptation to use the engine’s power band keeps the fuel consumption higher than a more sensible vehicle. These numbers, while technically accurate, likely represent the extreme low end for owners who aren’t afraid to use the throttle.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Audi R8 at $3,850. This figure is based on driving 15,000 miles per year, with 45% of those miles driven in the city and 55% on the highway, using the national average fuel price at the time of calculation for premium gasoline. It’s a substantial sum, exceeding the annual fuel cost of many SUVs and trucks. Potential R8 buyers should treat this number as a minimum. Aggressive driving, optional track days, and spirited weekend jaunts will undoubtedly push that figure considerably higher. Premium fuel is required, adding to the overall expense.

Real-world expectations

Real-world fuel economy for the R8 varies significantly, depending on driving style and conditions. While some owners might achieve the EPA estimates during exceptionally gentle highway cruising, most will likely see figures below the official ratings, particularly in mixed driving. The intoxicating exhaust note and readily available power encourage frequent bursts of acceleration, and resisting that urge is difficult. Consequently, frequent fuel stops are a reality.

How it compares

Compared to its competitors, the Audi R8’s fuel economy paints a clear picture. The Lamborghini Huracan, which shares a similar powertrain architecture, posts nearly identical figures, hovering around 13 MPG city and 18 MPG highway. A Porsche 911 Turbo S, with its turbocharged engine, manages a slightly better 17 MPG city and 24 MPG highway, showcasing the efficiency benefits of forced induction. Even the Mercedes-AMG GT Black Series, a track-focused machine, achieves a comparable city rating, but exceeds the R8 on the highway. The R8’s fuel consumption is simply the price you pay for a naturally aspirated V10 experience. Whether or not that trade-off is acceptable depends entirely on the individual buyer’s priorities. The R8 buyer is willing to sacrifice a few MPG for the sound, responsiveness, and character of the V10, a trait not shared with every performance car.

Tips to maximize efficiency

While fuel economy is unlikely to be a primary concern for R8 owners, there are steps to minimize consumption. Avoid short trips where the engine doesn’t reach optimal operating temperature. Cold starts are particularly inefficient and quickly deplete the fuel tank. Combining errands into fewer trips can reduce overall fuel usage.

Use the Audi Drive Select system to choose the most appropriate driving mode. The “Comfort” or “Auto” modes will generally provide better fuel economy than “Dynamic,” which sharpens throttle response and holds gears longer. Resist the urge to constantly accelerate and decelerate aggressively. Smooth, consistent driving minimizes fuel consumption.

Regular maintenance is critical for optimal engine performance and fuel efficiency. Ensure the engine is properly tuned and that the air filter is clean. A clogged air filter restricts airflow, forcing the engine to work harder and consume more fuel. Also, properly inflated tires reduce rolling resistance, improving fuel economy. Check tire pressures regularly and inflate them to the recommended levels.

Minimize idling. Modern engines are designed to be shut off rather than left idling for extended periods. If you’re stopped for more than a minute or two, turn off the engine. This simple habit can save a surprising amount of fuel over time. View all Audi fuel economy data to compare the R8 to other cars in the lineup.
