29 MPG combined isn’t a headlining figure, but it’s a quiet triumph for the 2021 Lexus LC 500h. This isn’t a Prius in a fancy suit; it’s a grand touring coupe draped in sheet metal that still stops traffic, packing a complex hybrid powertrain designed to enhance, not detract from, the driving experience. The LC 500h isn’t about chasing every last fraction of a mile per gallon. It’s about luxurious, effortless performance with a respectable degree of efficiency. Its buyers are motivated by style, comfort, and the unique Lexus driving experience, fuel economy is a secondary, albeit appreciated, advantage.

City and highway performance

The LC 500h showcases a noticeable difference between its city and highway figures. The EPA estimates 26 MPG in the city, a number that benefits greatly from the hybrid system’s ability to recapture energy during braking and use electric power at lower speeds. Stop-and-go traffic, the bane of many powerful engines, becomes a zone of relative efficiency for the LC 500h. Out on the open road, the highway figure climbs to 34 MPG. This is where the 3.5L V6 engine takes more of the workload, complemented by the electric motor to deliver smooth and strong acceleration for confident passing maneuvers. The unique Automatic (AV-S10) transmission, a combination of a four-speed automatic and a continuously variable transmission (CVT), further optimizes fuel economy on the highway by keeping the engine in its most efficient rev range.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Lexus LC 500h to be precisely $2,000. This figure is based on driving 15,000 miles per year, using national average fuel prices. Your particular fuel costs will fluctuate based on your driving habits, the type of fuel you use, and where you live. Premium fuel is recommended, if not required, for optimal performance, and this also impacts the annual cost. The $2,000 benchmark provides a clear indication of what to expect for most owners who put a typical number of miles on this car.

Real-world expectations

While the EPA provides a standardized benchmark, real-world fuel economy can vary considerably. The LC 500h’s performance is particularly sensitive to driving style. A heavy foot will quickly diminish the benefits of the hybrid system, pushing the MPG closer to what you might expect from a traditional V6-powered coupe. Those who embrace a more deliberate driving style, and who use the available driving modes effectively, will likely find themselves meeting or even exceeding the EPA estimates. Highway cruising can often yield exceptional results as the hybrid system blends electric assistance with the V6 engine. All Lexus fuel economy data is available on our website.

How it compares

The LC 500h doesn’t have many direct rivals, blurring the lines between luxury coupes and hybrid performance cars. A Porsche 911 Carrera S delivers exhilarating performance, but it achieves only around 21 MPG combined. A BMW 8 Series Gran Coupe, another stylish contender, sits in a similar range, around 22 MPG combined. These more performance-oriented alternatives prioritize power and handling over less gas. Within the Lexus family, the RC 350, a more conventional coupe, manages around 23 MPG combined. The buyer considering the LC 500h will find more favorable fuel economy with the hybrid LC, but ultimately prioritizes aesthetics and exclusivity. Compare LC MPG across all years here.

Tips to maximize efficiency

Take advantage of the LC 500h’s drive modes. The “Eco” mode optimizes the powertrain for maximum efficiency, softening throttle response and prioritizing electric power where possible. It might slightly reduce the car’s responsiveness, but it can make a noticeable difference in fuel consumption, especially in city driving.

Practice smooth acceleration and braking. Avoid sudden bursts of speed and hard braking, as these actions waste energy. Gently accelerate and brake gradually to allow the hybrid system to recapture more energy and use electric power more effectively. Anticipate traffic flow and maintain a consistent speed to minimize unnecessary acceleration and deceleration.

Pay attention to tire pressure. Properly inflated tires reduce rolling resistance, which can improve fuel economy. Check your tire pressure regularly and ensure it matches the recommended level specified on the doorjamb sticker. A few extra PSI can make a small but measurable difference over time.

Minimize accessory usage. Running the air conditioner, especially at full blast, can decrease fuel economy. Use the climate control system carefully and consider opening the windows when appropriate. Limiting the use of other power-draining accessories can help preserve fuel.
