With 25 MPG combined, the 2022 Lexus RC 300 2.0L 4-cyl prioritizes aesthetics and a luxurious experience over fuel savings. It’s a sporting coupe, and while efficiency matters, it’s secondary to sleek styling and a comfortable drive. The RC 300 appeals to buyers who value curb appeal and Lexus qualities more than maximizing miles per gallon.

City and highway performance

The RC 300’s EPA rating is 21 MPG in the city and 31 MPG on the highway. The city figure reflects stop-and-go driving, as the engine works harder during frequent acceleration and deceleration. The highway number shows the engine’s efficiency at cruising speed. The eight-speed automatic transmission optimizes fuel economy. A wide range of ratios allows the engine to operate efficiently at various speeds, contributing to the highway figure.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Lexus RC 300 2.0L 4-cyl at $2,300. This is based on driving 15,000 miles per year, using national average fuel prices at the time of calculation. This is an estimate, so actual fuel costs will vary depending on driving habits, city versus highway driving, and fuel price changes. A lead foot will increase this number, while consistent highway driving will likely decrease it.

Real-world expectations

EPA estimates provide a baseline, but real-world fuel economy often differs. RC 300 drivers report figures around the combined rating, slightly above or below, depending on their commute. Aggressive driving will lower numbers toward the city estimate, while smooth acceleration and steady highway speeds can approach 31 MPG. Lexus specifies premium gasoline for the RC 300, which affects the car’s performance and consumption.

How it compares

The RC 300’s fuel economy is mid-range compared to its competitors. A BMW 430i Coupe achieves 28 MPG combined, appealing to those seeking a balance of sport and efficiency. The Infiniti Q60, with its V6 engine, usually gets less MPG than the RC 300, around 22 MPG combined, trading MPG for horsepower. All Lexus fuel economy data shows a focus on respectable mileage in the luxury segment, and the RC 300’s figures align with this. The Cadillac CT5 with the available 2.0L Turbo I4 engine gets up to 23 MPG combined. For more, explore RC MPG across all years to see trends and other engine options.

Tips to maximize efficiency

Accelerate smoothly and gradually . Avoid rapid speed increases, as these consume more fuel. The RC 300’s turbocharged engine responds well to a light foot, maintaining momentum without burning excess gasoline.

Maintain a consistent speed on the highway, using cruise control where possible. Varying speeds require constant engine adjustments, increasing fuel consumption. Cruise control helps the RC 300 run efficiently.

Ensure proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and reducing fuel economy. Regularly check tire pressure and inflate to the levels on the sticker inside the driver’s side door jamb.

Minimize idling. Idling wastes fuel, especially in turbocharged engines. If stopped for more than a minute, turn off the engine. The RC 300 restarts quickly, saving fuel without sacrificing comfort.

Remove unnecessary weight. Extra cargo strains the engine, impacting fuel economy. Regularly remove unneeded items, such as sports equipment or tools not needed for daily driving.
