21 MPG combined probably isn’t the most important figure for someone considering a 2019 Lexus RC 350 AWD. Owners accept it as the price for a stylish, comfortable coupe with smooth power and the added confidence of all-wheel drive. This isn’t a car for commuters squeezing every last tenth of a mile per gallon; it’s a statement purchase. Enjoying the drive is the point.

City and highway performance

The EPA estimates for the 2019 Lexus RC 350 AWD are 18 MPG in the city and 24 MPG on the highway. The highway number is good for a V6 coupe with all-wheel drive, but the city figure shows the engine’s thirst. Stop-and-go traffic and frequent acceleration hurt efficiency. On the open road, however, the RC is more relaxed, proving it’s a comfortable long-distance cruiser.

Annual fuel cost

The EPA estimates the annual fuel cost for a 2019 Lexus RC 350 AWD at $2,750. This is based on 15,000 miles per year and national average fuel prices. Your actual fuel costs may vary depending on your driving, the type of fuel, and gas prices. This car prefers premium fuel, so you’ll pay more each time you fill up.

Real-world expectations

EPA estimates are a useful benchmark, but real-world fuel economy often differs. The RC 350’s 3.5L V6 encourages spirited driving, and using the throttle often will lower MPG. Drivers who prioritize a smooth, consistent pace and minimize hard acceleration are more likely to get numbers closer to the EPA estimates. Weather and terrain matter too. Expect lower fuel economy in colder climates or hilly areas. Check out RC MPG across all years to see owner-submitted figures.

How it compares

The RC 350’s fuel economy puts it in a specific segment. The BMW 430i xDrive coupe gets a slightly better EPA combined rating of 27 MPG because of its turbocharged four-cylinder engine. Some drivers prefer the smoother power of the Lexus’s V6. The Infiniti Q60 AWD is closer to the RC 350 with an EPA combined rating of 22 MPG. The Audi A5 Coupe, with Quattro all-wheel drive, gets a combined 27 MPG. To look at other Lexus models, you can view all Lexus fuel economy data.

Tips to maximize efficiency

The RC 350’s driving mode selector has an “Eco” mode. This adjusts the throttle response and transmission to prioritize fuel efficiency. It might dampen the car’s sporty character, but it can make a difference, especially in city driving.

Make sure your tires are inflated. Underinflated tires increase rolling resistance, which makes the engine work harder and uses more fuel. Check your tire pressure regularly and keep it at the recommended levels.

Avoid aggressive driving like hard acceleration and sudden braking. Smooth driving improves fuel economy and reduces wear on the vehicle.

Minimize idling. If you’re stopped for more than a minute, turn off the engine. Modern cars restart quickly, making it more fuel-efficient to switch off the engine than to let it idle.

Consider using cruise control on the highway. Maintaining a constant speed eliminates speed fluctuations, which can reduce fuel consumption. The RC 350’s adaptive cruise control adjusts speed to maintain a safe following distance, improving efficiency.
