The 2021 Lexus LC 500 gets 19 MPG combined. This number likely isn’t a concern for the typical LC 500 buyer, who is focused on the excitement of its naturally aspirated 5.0L V8 engine and attractive coupe design. This isn’t a vehicle purchased for efficiency, it’s an emotional purchase for those who appreciate a refined, powerful grand tourer.
City and highway performance
The EPA estimates the LC 500 gets 16 MPG in the city and 25 MPG on the highway. These figures are what you can expect from a high-performance V8. Stop-and-go city driving uses more fuel because the engine works harder to accelerate its nearly 4,300-pound curb weight. The highway number, while better, still reflects the engine’s displacement and power output. Expect to see the higher end of that range when cruising steadily, and the lower end when frequently passing or driving on steep grades.
Annual fuel cost
The EPA estimates the annual fuel cost for the 2021 Lexus LC 500 at $3,050. This calculation assumes 15,000 miles of driving per year and the national average fuel price for premium gasoline, which this car requires. Note that individual fuel costs will vary depending on driving habits, local fuel prices, and the percentage of city versus highway driving.
Real-world expectations
The EPA provides a standardized benchmark, and real-world fuel economy can differ. Drivers who accelerate quickly frequently or often engage the LC 500’s Sport modes will likely see numbers below the EPA estimates. However, those who accelerate smoothly and use the automatic transmission’s higher gears efficiently may achieve slightly better results. The LC 500’s fuel economy is highly sensitive to driving style.
How it compares
The LC 500’s fuel economy is lower than some of its competitors. For example, the BMW 840i Coupe, with its turbocharged inline-six, achieves a combined 25 MPG. The Porsche 911 Carrera, a benchmark sports car, manages around 21 MPG combined, even with its impressive performance. The Mercedes-AMG GT generally gets around 16-19 MPG combined, depending on engine configuration. These comparisons matter to buyers, highlighting the trade-offs between performance, engine character, and efficiency. Some buyers may also be interested in the LC MPG across all years to see if other model years have better fuel efficiency.
Tips to maximize efficiency
Anticipate traffic flow to minimize abrupt acceleration and braking. The LC 500’s strong engine response can be tempting, but smooth, gradual inputs will conserve fuel. This car weighs over two tons so braking efficiently and early will also help tremendously.
Use the cruise control system on the highway to maintain a consistent speed and reduce unnecessary throttle adjustments. Avoiding frequent passing and maintaining a steady pace will contribute to improved fuel economy.
Ensure the tires are properly inflated to the recommended pressure. Underinflated tires increase rolling resistance, which negatively impacts fuel economy. Tire pressure monitoring systems on newer models can help with this.
Avoid extended idling. If you’re stopped for more than a minute or two, turn off the engine. Modern engines are designed to restart quickly and efficiently, minimizing any potential wear and tear. Doing this in the LC 500 will also help reduce unwanted noise.
Consider using the “Comfort” or “Eco” driving modes, if available. These modes typically adjust throttle response and transmission shift points to prioritize fuel efficiency over performance. You can find all Lexus fuel economy data online from the EPA.
