The 2023 Lexus RC 300, with its 2.0-liter turbocharged four-cylinder engine, gets 25 MPG combined, which isn’t record-breaking. That places the RC in the middle of the sporty coupe segment. Many buyers accept this trade-off for Lexus luxury, sharp styling, and responsive driving. This RC is for those who appreciate a well-crafted coupe with some performance.

City and highway performance

The RC 300’s EPA estimates are 21 MPG in the city and 31 MPG on the highway. The city number reflects urban driving’s stop-and-go nature, where the engine idles and accelerates more. The turbocharged engine works harder in these conditions. The 31 MPG highway figure is better and achievable when cruising at a consistent speed. The eight-speed automatic transmission helps highway fuel economy, keeping the engine at its best at higher speeds.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Lexus RC 300 2.0L at $2,300. This is based on driving 15,000 miles per year and using national average fuel prices. Your fuel costs will vary with your driving habits, fuel type, and local prices. Premium fuel is recommended for optimal performance, which will increase gas costs. Adjust your expectations if you drive significantly more or less than 15,000 miles annually.

Real-world expectations

EPA estimates are a baseline, but real-world fuel economy often differs. Aggressive driving, short trips, and extra weight can decrease MPG. The urge to enjoy the RC 300’s performance can affect fuel efficiency. Drivers who accelerate smoothly and anticipate traffic are more likely to get closer to EPA estimates. Consult RC MPG across all years to see previous model years’ performance.

How it compares

The Lexus RC 300’s fuel economy is competitive compared to rivals. The BMW 430i Coupe gets a combined 28 MPG with its 2.0-liter turbo engine, which is better than the RC 300. The Audi A5 Coupe with its 2.0-liter turbo also manages 28 MPG combined. Meanwhile, the Infiniti Q60 gets around 22 MPG combined with its base engine, despite more powerful engine options being available. Some buyers accept the RC’s fuel consumption for Lexus’s reliability and styling. Access all Lexus fuel economy data to see how the brand’s vehicles compare.

Tips to maximize efficiency

Use the RC 300’s drive modes. “Eco” mode prioritizes fuel efficiency by adjusting throttle response and transmission mapping, which can improve MPG during commutes, though it might reduce performance slightly.

Keep your tires inflated. Underinflated tires increase rolling resistance, reducing your fuel economy. Check your tire pressure and inflate them to the recommended pressure listed on the driver’s side doorjamb.

Avoid aggressive acceleration and braking. Smooth inputs are key to maximizing fuel efficiency. Anticipate traffic and maintain a steady speed. The RC 300 is fun to drive, but easy acceleration will save gas.

Minimize idling. Turn off the engine if you’re stopped for more than a minute. Modern engines restart frequently without excessive wear. Cutting the engine at long red lights can improve city fuel efficiency.

Reduce weight. Remove unnecessary items from the trunk and passenger compartment. Extra weight strains the engine, consuming more fuel. A lighter car is more economical, even with a turbocharger.
