19 MPG combined is what you get with the Lexus RC F. This isn’t a hybrid designed for efficiency. It’s a naturally aspirated performance coupe that focuses on thrills over fuel stops. RC F buyers expect some fuel consumption as part of the car’s character.

City and highway performance

The RC F’s EPA ratings are 16 MPG in the city and 24 MPG on the highway. Stop-and-go traffic lowers fuel economy as the 5.0-liter V8 works harder. Highway driving is a bit better. While 24 MPG won’t beat hybrid sedans, it’s reasonable for a performance car with this power. The eight-speed automatic transmission helps, with tall gearing for relaxed cruising. However, quick acceleration will waste gas, reminding you of the engine’s thirst. Understanding your driving style impacts fuel consumption.

Annual fuel cost

The EPA estimates an annual fuel cost of $3,050 for the RC F. This is based on 15,000 miles per year, city and highway driving, and national average fuel prices (for premium fuel). This is an estimate. Your fuel costs will vary depending on how much and where you drive, your driving style, and fuel prices. But it’s a benchmark for understanding the cost of owning this coupe. Expect to exceed $3,050 if you drive mostly in the city or drive aggressively.

Real-world expectations

The EPA provides an estimate, but real-world fuel economy can differ. RC F owners often report slightly lower numbers than the official ratings, especially in mixed conditions. This reflects the enthusiastic driving style of many RC F owners. The car encourages exploring its performance, which uses more fuel. Consistent highway cruising can yield results closer to the EPA’s 24 MPG estimate. Understanding your driving habits is important.

How it compares

The RC F’s fuel economy is similar to other performance coupes. The BMW M4 Competition, with a twin-turbocharged inline-six, gets 16 MPG city and 23 MPG highway. The Audi RS5 gets 18 MPG city and 26 MPG highway, slightly better thanks to forced induction and a smaller engine. A Ford Mustang GT with the 5.0L Coyote V8 gets around 15 MPG city and 24 MPG highway. These comparisons matter less to the RC F buyer. They aren’t choosing an M4 for lower fuel costs. They’re choosing the RC F for its driving experience, styling, and naturally aspirated V8. Fuel economy is a consideration, but not the main one.

Tips to maximize efficiency

The RC F isn’t designed for efficiency, but you can improve mileage. Avoid idling, as the engine uses fuel even when stopped. If stopped for more than a minute, turn off the engine. Aggressive acceleration and hard braking use a lot of fuel. Smooth acceleration and anticipating traffic will help.

Maintain your RC F per the manufacturer’s recommendations. Regular oil changes, properly inflated tires, and a clean air filter help engine performance and efficiency. Make sure tires are at the recommended pressure. Underinflated tires increase rolling resistance, forcing the engine to work harder.

Use the car’s drive mode selector. “Normal” or “Eco” modes (if equipped) offer relaxed throttle mapping and earlier upshifts, prioritizing fuel efficiency. These modes might reduce the driving experience, but they are effective when fuel economy is important. If you’re curious about RC MPG across all years, we have historical data available.

Plan your routes. Avoiding congested areas and peak times reduces stop-and-go driving, which hurts fuel economy. Using navigation apps to find the most efficient route can save time and fuel. Careful planning can make a difference, even in the RC F.
