The 2020 Lexus RC F’s 19 MPG combined won’t earn it any fuel efficiency awards, but that’s not the point of this car. It’s a naturally aspirated, high-revving, V8-powered performance coupe. It was built for a visceral driving experience that prioritizes sound and feel over saving fuel. The RC F appeals to a specific buyer. Someone who values old-school character and reliability over outright efficiency and cutting-edge technology. They understand that a powerful engine requires fuel, and they are willing to pay the price for the unique thrills this car delivers.

City and highway performance

The EPA estimates the 2020 Lexus RC F will achieve 16 MPG in the city and 24 MPG on the highway. The city number is expected given the engine’s size and stop-and-go traffic prevents the V8 from operating efficiently. The highway figure is respectable. The eight-speed automatic transmission helps optimize fuel consumption at cruising speeds in higher gears. However, the temptation to accelerate and hear the engine’s roar often affects real-world highway mileage.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Lexus RC F at $3,050. This is based on driving 15,000 miles per year and using national average fuel prices. Premium fuel (required for optimal performance in the RC F) can significantly impact this annual cost, especially with fluctuating gas prices. This $3,050 shows how much more this performance car could cost compared to a hybrid or other fuel-efficient vehicle.

Real-world expectations

EPA estimates provide a baseline, but real-world fuel economy for the RC F varies depending on driving style and conditions. Aggressive acceleration, frequent Sport mode use, and spirited driving on winding roads will decrease fuel mileage. Conservative driving, longer highway stretches, and gentle acceleration may allow some drivers to get close to EPA estimates. Most RC F owners prioritize performance over fuel savings. Therefore, the number on the window sticker is often more of a suggestion.

How it compares

The RC F’s fuel economy is comparable to its competitors. The BMW M4 delivers about 19 MPG combined using its turbocharged six-cylinder engine. The Mercedes-AMG C63 S Coupe, with its twin-turbo V8, is rated at 20 MPG combined. The all-wheel-drive Audi RS5 achieves only 21 MPG combined despite its smaller displacement V6. The RC F buyer isn’t considering a Prius. They’re choosing the character of a naturally aspirated V8, likely finding the smile worth the trade-off.

Tips to Maximize Efficiency

Avoid flooring it at every opportunity. The RC F’s naturally aspirated V8 is tempting, but gentle acceleration will significantly improve your city MPG because, even though the engine might enjoy high RPMs, premium fuel is expensive.

Use the paddle shifters on the steering wheel to upshift early. Keep the engine in lower RPMs when cruising. The eight-speed automatic is responsive, and you can fine-tune its shift points for maximum efficiency when fuel conservation is the goal.

Make sure your tires are properly inflated. Underinflated tires increase rolling resistance, which hurts fuel economy. Check the tire pressure regularly and inflate to the recommended levels, which can be found on the driver’s side door jamb.

Consider using the “Eco” driving mode for relaxed cruising, as it optimizes the engine and transmission for fuel efficiency by slightly reducing power output. It offers a more relaxed driving experience.

Minimize weight in the vehicle. Extra cargo adds to the load the engine has to carry, reducing fuel efficiency. Remove any items you don’t need from the trunk and rear seats to reduce weight. Be sure to check out all Lexus fuel economy data for more context.
