19 MPG combined is not going to win the LC 500 any awards for fuel efficiency. But anyone considering this naturally aspirated V8 grand tourer understands that efficiency is not the point. This is a machine built for a visceral driving experience and head-turning style, and its relatively thirsty engine is simply part of the deal.
City and highway performance
The EPA estimates suggest 16 MPG in city driving and 25 MPG on the highway. The city number reflects the LC 500’s weight and the old-school V8’s tendency to consume more fuel in stop-and-go conditions. The highway figure is more respectable, due partly to the smooth-shifting 10-speed automatic transmission that allows the engine to cruise at lower RPMs. However, resist the urge to bury the throttle, and you will want to and you’ll see the highway MPG drop quickly.
Annual fuel cost
The EPA estimates the annual fuel cost for the 2023 Lexus LC 500 at $3,050. This figure is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway. It also uses current national averages for fuel prices. Your actual fuel costs could be higher or lower than this figure, depending on your driving habits and the prevailing fuel prices in your area. Aggressive driving, frequent short trips, and a heavier foot on the accelerator will all contribute to increased fuel consumption.
Real-world expectations
Real-world fuel economy will likely vary from the EPA estimates. Drivers who spend most of their time in urban environments with heavy traffic may struggle to match 16 MPG. Likewise, those who frequently indulge in spirited driving on winding roads may find the highway MPG closer to 20 than 25. It’s a trade-off: you get the exhilarating sound and response of a naturally aspirated V8, but you also pay at the pump. Before making a final decision, browse LC MPG across all years.
How it compares
Compared to its competitors, the LC 500’s fuel economy is mid-pack. The BMW 8 Series, specifically the 840i model with its turbocharged inline-six engine, offers significantly better fuel economy, rated at 25 MPG combined. The Porsche 911 Carrera S, while offering similar performance, manages around 21 MPG combined. Even the Jaguar F-Type P450, with its supercharged V8, hovers around 19 MPG combined, although some drivers report better real world numbers. These alternatives offer better fuel economy, but sacrifice the naturally aspirated V8’s immediacy.
Tips to maximize efficiency
Although the LC 500 prioritizes performance over efficiency, there are still steps you can take to minimize fuel consumption. The car is equipped with selectable drive modes; using “Eco” mode will soften throttle response and optimize transmission shift points for better fuel economy. Don’t expect a transformation, but it can make a small difference, especially during commuting.
Avoid aggressive acceleration and braking. The V8’s power is intoxicating, but rapid acceleration will quickly drain the fuel tank. Gentle and consistent throttle inputs are far more efficient. Anticipate traffic flow and coast whenever possible to reduce the need for hard braking.
Proper tire inflation is critical for both safety and fuel economy. Check your tire pressures regularly and ensure they match the recommended specifications found on the doorjamb or in the owner’s manual. Under-inflated tires create more rolling resistance, which reduces fuel efficiency.
Finally, remember that the LC 500 performs best with premium fuel. While it might run on regular, using premium gasoline will ensure optimal engine performance and efficiency. The engine management system is calibrated to take advantage of the higher octane rating.
Ultimately, the 2023 Lexus LC 500 is a statement. It’s a symbol showcasing driving purity and traditional style which you can explore further in all Lexus fuel economy data. Its fuel usage is a secondary consideration.
