With 29 MPG combined, the 2024 Lexus LC 500h isn’t the most fuel-efficient, but it’s acceptable for a grand touring coupe made for cross-country trips. This isn’t a vehicle for hypermilers; it’s for drivers who want refined performance and unique styling and are okay with moderate gas bills.

City and highway performance

The LC 500h gets an EPA-estimated 26 MPG in the city and 33 MPG on the highway. These numbers show how the hybrid powertrain works. The electric motor helps fuel economy in stop-and-go traffic. On the open road, the 3.5L V6 engine takes over, still offering respectable efficiency for its size and power. Driving style greatly affects these numbers. Aggressive driving will lower the MPG. A more relaxed approach, using the hybrid system well, will get you closer to the EPA estimates.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Lexus LC 500h is $2,000. This is based on driving 15,000 miles per year and using national average fuel prices. Fuel prices change, and your actual fuel costs will vary based on your driving habits and the cost of gas in your area. However, $2,000 is a good benchmark for budgeting and helps show the LC 500h’s fuel use within its class. Comparing it to other vehicles you’re considering helps show the cost of ownership.

Real-world expectations

EPA estimates give a standard comparison, but real-world fuel economy changes. Many things affect fuel use, including driving style, traffic, terrain, and tire pressure. LC 500h owners say their numbers generally match the EPA estimates, with some getting slightly better or worse MPG based on their usual routes. People who focus on smooth acceleration and frequent regenerative braking are more likely to get the advertised fuel efficiency. Owners who enjoy the car’s performance may see fuel economy decline. Always check LC MPG across all years to compare data.

How it compares

The LC 500h is unique compared to other grand touring coupes. The BMW 840i Coupe, with its 3.0L turbocharged inline-6, gets around 25 MPG combined. The BMW offers a sportier driving experience for some, but the LC 500h has its hybrid powertrain and Lexus reliability. The Porsche 911 Carrera, a benchmark for performance coupes, gets around 21 MPG combined with its base engine. Outside the coupe segment, the Lexus LS 500h sedan, which has a similar hybrid powertrain, gets around 25 MPG combined. These comparisons show that the LC 500h is a reasonable mix of performance and efficiency, especially compared to its rivals. For a complete view, check all Lexus fuel economy data.

Tips to maximize efficiency

Use the LC 500h’s Eco driving mode. This mode changes throttle response and climate control to prioritize fuel efficiency, which is helpful in city driving where maximizing electric motor use is beneficial.

Drive and brake smoothly. Avoid quick starts and stops, which use more fuel. Let the regenerative braking system recapture energy by anticipating traffic and slowing down gently.

Keep tires properly inflated. Underinflated tires increase rolling resistance, which lowers fuel economy. Check your tire pressure often and inflate tires to the recommended level, which is on the sticker inside the driver’s side door.

Avoid idling. Idling uses fuel without going anywhere. If you’ll be stopped for more than a minute, turn off the engine.

Reduce weight. Extra weight in the vehicle hurts fuel economy. Remove unnecessary items from the trunk and passenger area to improve efficiency.
