19 MPG combined is not a number Lexus LC 500 buyers typically fixate on. This isn’t a Prius; it’s a grand touring coupe designed to offer a sensory experience above all else. Fuel efficiency plays a minor role in the purchase decision for a car this stylish and special, a car that prioritizes a naturally aspirated V8 engine note over outright practicality.

City and highway performance

The LC 500’s EPA estimates reveal a stark contrast between city and highway driving. The 16 MPG in the city reflects the engine’s inherent thirst, exacerbated by stop-and-go traffic where the 10-speed automatic transmission cycles frequently. Out on the open road, the LC 500 fares considerably better, achieving 25 MPG. This figure is more palatable for long-distance cruises, where the engine settles into a relaxed rhythm and the advanced aerodynamics come into play. These numbers underscore that the LC 500 is best enjoyed, and most efficiently operated, on the highway.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2019 Lexus LC 500 is $3,050. This figure is based on driving 15,000 miles per year, with 45% of those miles driven in the city and 55% on the highway. It also assumes a national average fuel price, which can, of course, fluctuate significantly depending on location and the grade of fuel used. This $3,050 figure provides a benchmark for potential running costs, but individual expenses will vary based on driving habits and gasoline prices. Keep in mind that premium fuel is recommended for optimal performance, so that cost is baked into the EPA’s estimate.

Real-world expectations

While the EPA provides a standardized benchmark, real-world fuel economy often deviates. LC 500 drivers who enjoy the engine’s responsiveness and exhilarating sound may see numbers closer to the city estimate, even on mixed driving routes. Conversely, those who prioritize smooth, consistent highway speeds can realistically achieve, or even slightly exceed, the EPA’s 25 MPG rating. The key is moderation; aggressive acceleration and frequent heavy braking will quickly diminish fuel efficiency in any vehicle, particularly one with a high-performance engine like this.

How it compares

The LC 500 exists in a rarefied segment, but its fuel economy can be compared to similar vehicles. For instance, the V8-powered BMW M850i xDrive coupe, while offering superior horsepower and all-wheel drive, achieves a slightly better 20 MPG combined. A Porsche 911 Carrera S, known for its blend of performance and relative efficiency, manages 21 MPG combined, thanks to its turbocharged flat-six engine. The Maserati GranTurismo, another stylish Italian grand tourer, offers a similar experience to the LC 500 but achieves a dismal 15 MPG combined. The LC buyer isn’t cross-shopping a Prius, but this relative comparison sheds light on the fuel cost implications of choosing a high-performance GT coupe.

Tips to maximize efficiency

Use the paddle shifters strategically. The LC 500’s 10-speed automatic is generally very good, but shifting manually, particularly on downhills or while approaching a stop, allows for more precise engine braking and reduces reliance on the friction brakes, preserving momentum and saving fuel.

Keep the car properly maintained. A well-tuned engine, clean air filter, and correctly inflated tires contribute to optimal engine performance and fuel efficiency. Adhering to the recommended maintenance schedule will ensure that the LC 500 operates as efficiently as possible.

Consider using the “Comfort” driving mode in low-speed situations. While “Sport” and “Sport+” modes enhance throttle response and shift points for a more engaging drive, “Comfort” mode softens the throttle and encourages earlier upshifts, thus reducing fuel consumption in stop-and-go traffic. Remember that LC MPG across all years will vary according to driving style.

Avoid unnecessary idling. Letting the engine idle for extended periods wastes fuel and contributes to unnecessary emissions. If you anticipate a long wait, it is best to turn off the engine.

Plan your routes and avoid peak traffic hours when possible. By minimizing stop-and-go driving, you can significantly improve your fuel economy. Using navigation apps to identify and avoid congested areas can help reduce your overall fuel consumption.
