The 2022 Lexus RC 300 AWD gets 22 MPG combined, which won’t win any fuel efficiency awards. Buyers in this segment aren’t usually prioritizing that anyway. This all-wheel-drive coupe, equipped with a 3.5L V6, is for drivers who want style, luxury, and a rewarding driving experience over saving gas. Lexus understands that those drawn to the RC’s sculpted lines and comfortable interior are willing to trade a few MPGs for the added confidence of all-wheel drive and the smooth power of a V6.

City and highway performance

The EPA estimates the 2022 RC 300 AWD gets 19 MPG in the city and 26 MPG on the highway. The city figure reflects stop-and-go traffic, where the V6 engine’s efficiency drops. On the open road, the RC 300 AWD does better, allowing relaxed cruising and decent mileage, although still behind some turbocharged competitors. Aggressive driving will reduce these numbers, especially in cities. Drivers who spend most of their time on city streets will likely see fuel consumption closer to 19 MPG, while those who frequently drive on the highway may experience figures closer to or even slightly above 26 MPG.

Annual fuel cost

The EPA says the annual fuel cost for the 2022 Lexus RC 300 AWD is $2,650. This is based on driving 15,000 miles per year and using national average fuel prices. Fuel prices change, and your actual costs may vary depending on how you drive and the price of gas where you live. This estimated annual cost is a useful benchmark for comparing the RC 300 AWD’s fuel consumption to other vehicles, but it is not a guaranteed expense. Using premium fuel will likely cause it to be higher.

Real-world expectations

EPA estimates offer a standard comparison, but real-world fuel economy often differs. Driving style, road conditions, and even tire pressure affect the numbers you’ll actually see. The RC 300 AWD performs best with smooth acceleration and consistent speeds. Frequent bursts of acceleration and hard braking will quickly lower fuel efficiency. Regular maintenance, including proper tire inflation and timely oil changes, helps maintain fuel consumption. Owners reporting their results on sites like Fuelly.com suggest that achieving the EPA combined figure of 22 MPG is realistic, but requires effort and a commitment to efficient driving.

How it compares

Competitors like the BMW 430i xDrive coupe get a combined 28 MPG with its turbocharged four-cylinder engine, a more efficient choice. The Audi A5 quattro coupe also gets a slightly better combined rating of 27 MPG. Even the Infiniti Q60 AWD, which is also a sporty luxury car, manages a combined 22 MPG when equipped with its base engine, matching the Lexus. However, the RC buyer might prefer the Lexus’ V6 over the turbocharged engines of its rivals. The smooth power and distinctive engine sound of the V6 often outweigh the small fuel savings offered by smaller engines to these drivers.

Tips to maximize efficiency

Use the RC’s drive modes. The “Eco” mode adjusts throttle response and transmission settings to prioritize fuel efficiency. This is ideal for commuting and highway driving. Using “Normal” or “Sport” modes sparingly will reduce fuel consumption, whereas you might be tempted to unleash the V6’s power.

Drive smoothly, keeping your speed consistent. Avoid aggressive acceleration and hard braking, which decrease fuel economy. Anticipate traffic flow and maintain a steady pace when possible. The RC 300 AWD is designed for refined performance, not racing.

Check your tires and make sure they are inflated correctly. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly and inflate them to the recommended level as indicated on the doorjamb sticker.

Remove extra weight. Carrying unnecessary cargo adds to the vehicle’s overall weight, impacting fuel efficiency. Remove any items you don’t need to lighten the load and improve your MPG.

Consider cruise control on the highway to help maintain a consistent speed, minimizing unnecessary acceleration and deceleration. This can improve fuel economy on long highway drives, especially on relatively flat roads.
