19 MPG combined isn’t going to break any fuel efficiency records, but that’s not really the point of the 2018 Lexus LC 500. This car is designed to deliver a specific, visceral experience: the smooth, effortless power of a naturally aspirated 5.0-liter V8 with striking design and that unmistakable Lexus air of high-quality craftsmanship. Buyers probably aren’t cross-shopping this car with a Prius. They’re seeking a grand tourer that blends performance and luxury in a unique way, and they’re willing to accept a relatively thirsty engine as part of the deal. Those wanting better mileage from the Lexus coupe can view LC MPG across all years to see if alternatives meet their needs; other Lexus models can be easily compared through all Lexus fuel economy data.

City and highway performance

The EPA estimates the 2018 Lexus LC 500 achieves 16 MPG in the city and 26 MPG on the highway. The city figure reflects stop-and-go conditions where the engine operates at less-than-ideal efficiency. Starting from a standstill, especially driving aggressively, uses more fuel. The 26 MPG highway rating is more respectable and achievable during sustained cruising. The LC 500’s 10-speed automatic transmission allows the engine to maintain lower, more efficient RPMs at higher speeds. However, even on the highway, aggressive acceleration or spirited driving will quickly drop that number.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Lexus LC 500 at $3,050. This figure is based on driving 15,000 miles per year and using national average fuel prices. It’s important to remember that this is an estimate. Your individual fuel costs will vary depending on your driving habits, the type of driving you do (city vs. highway), and the price of gasoline in your area. Fueling up isn’t inexpensive, but this is expected for a high-performance coupe in this segment.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy can vary significantly. Drivers who primarily use the LC 500 for short city trips will likely see MPG figures closer to the 16 MPG mark, or even lower if they drive aggressively. Those who predominantly drive on the highway and maintain a consistent speed may be able to achieve figures closer to, or even slightly exceeding, the EPA’s 26 MPG estimate.

However, the sound and immediate response of the V8 often encourages drivers to accelerate quickly, resulting in lower overall fuel economy. Consider the EPA numbers guidelines. Your right foot determines the real MPG.

How it compares

The LC 500’s fuel economy places it among its competitors. The BMW M850i xDrive coupe, with its turbocharged V8, offers similar performance but achieves a slightly better 20 MPG combined. A Porsche 911 Carrera S can achieve around 21 MPG combined. However, it’s a different driving experience. The Mercedes-AMG GT boasts similar horsepower but comes in around 18 MPG combined.

What the LC 500 offers buyers is character. The Lexus offers a unique blend of luxury, reliability, and V8 sound. Owners may accept the relatively middle-of-the-road fuel economy as a compromise for that experience.

Tips to maximize efficiency

Use the LC 500’s drive modes. Selecting “Eco” mode will adjust throttle response and shift patterns to prioritize fuel efficiency, which can be beneficial during highway cruising or daily commutes where you don’t need maximum performance. It might reduce some of the fun factor, but it’s a free way to save a little gas.

Avoid unnecessary idling. The LC 500’s V8 displaces 5.0 liters. It consumes a significant amount of fuel even when stationary. If you’re stopped for more than a minute, it’s more efficient to turn off the engine and restart it when you’re ready to go. The LC’s strong starter motor is ready for the task.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which forces the engine to work harder and reduces fuel economy. Check your tire pressure regularly and inflate them to the recommended pressure listed on the driver’s side door jamb. This simple maintenance task can make a noticeable difference.

Anticipate traffic flow. Smooth acceleration and braking are much more efficient than aggressive stop-and-go driving. Look ahead, anticipate changes in traffic, and maintain a consistent speed whenever possible. This driving style will not only improve fuel economy but also enhance the overall driving experience.
