18 MPG combined is the tradeoff for experiencing one of the most soulful engines currently in production. The 2024 Lexus LC 500 isn’t about efficiency; it’s about visceral thrills, stunning design, and a uniquely Japanese take on the grand touring coupe. Its buyers prioritize emotion and sensory experiences. They understand what they’re getting into, and they accept the fuel economy shortcomings willingly.

City and highway performance

The LC 500’s EPA ratings break down to 16 MPG in the city and 24 MPG on the highway. The in-city figure reflects the realities of stop-and-go driving, where the naturally aspirated 5.0-liter V8 isn’t operating at its most efficient. The highway number is more respectable, and attainable if you resist the urge to exploit the engine’s prodigious power. The 10-speed automatic transmission helps to optimize fuel efficiency, offering a wide range of ratios to keep the engine in its sweet spot. However, the engine’s defining characteristic, its instantaneous throttle response and eagerness to rev, can easily lead to lower real-world numbers, especially when using the paddle shifters for a glorious downshift.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Lexus LC 500 5.0L 8-cyl at $3,200. This figure is based on driving 15,000 miles per year and using national average fuel prices. Individual fuel costs will vary depending on driving habits, local fuel prices, and the grade of fuel used (premium is recommended for optimal performance). This $3,200 figure represents a significant expense, particularly compared to more fuel-conscious vehicles, and factors partly into the cost of ownership for this unique grand tourer.

Real-world expectations

While the EPA numbers provide a baseline, real-world fuel economy in the LC 500 is heavily dependent on driving style. Aggressive acceleration, frequent use of sport modes, and a predominantly city-based commute will likely result in numbers below the EPA estimates. Conversely, those who prioritize smooth, consistent speed on the open road may see figures closer to, or even slightly exceeding, the highway rating. The LC 500 has a relatively small fuel tank, so frequent fill-ups can be expected, particularly on longer journeys.

How it compares

The LC 500 exists in a rarefied segment where outright fuel efficiency is secondary to performance and aesthetics, but it’s worth considering the alternatives. The BMW M850i xDrive Coupe, with its twin-turbo V8, manages a slightly better 20 MPG combined. The Porsche 911 Carrera S, while offering comparable performance, achieves around 21 MPG combined. Even the Jaguar F-TYPE R, with its supercharged V8, is closer to the 24 MPG combined mark. These comparisons highlight the LC 500’s thirstier nature. However, the Lexus distinguishes itself with its striking design, exceptional build quality, and the unique character of its naturally aspirated engine. Those considering the LC 500 know that compromising slightly on fuel consumption nets them a more distinctive and reliable vehicle. The LC 500’s reliability and unique engine balance out its lower fuel economy.

Tips to maximize efficiency

Use the “Eco” drive mode when cruising. The LC 500’s drive mode selector can noticeably alter fuel consumption by adjusting throttle response and transmission behavior. Selecting “Eco” mode dulls the throttle input, encouraging a more relaxed driving style which positively impacts fuel economy.

Anticipate traffic flow to avoid sudden acceleration and braking. The LC 500’s powerful engine rewards smooth, gradual inputs. By anticipating changes in traffic, you can maintain a consistent speed and minimize the wasteful use of fuel associated with repeated acceleration.

Ensure tires are properly inflated. Under-inflated tires increase rolling resistance, negatively impacting fuel economy. Check tire pressures regularly and maintain them at the recommended levels specified on the door jamb sticker.

Minimize idling. Idling wastes fuel, especially in a large-displacement engine like the LC 500’s V8. If you anticipate being stationary for more than a minute, turn off the engine. Restarting the vehicle consumes less fuel than prolonged idling.

Consider exploring LC MPG across all years to see if earlier models offer an MPG profile that better suits your needs. You may also want to review all Lexus fuel economy data as you continue your vehicle research process.
