The 2022 Lexus RC 350 AWD’s 22 MPG combined fuel economy rating isn’t going to win any awards for lower fuel costs, but it’s likely not the most important factor for buyers of this stylish coupe. People buy this car for its looks, its luxurious interior, and the confident sound of its naturally aspirated V6 engine, not for maximizing gas mileage on the highway.

City and highway performance

The EPA estimates the RC 350 AWD will achieve 19 MPG in the city and 26 MPG on the highway. This difference reflects the engine’s tuning, which prioritizes responsiveness and power over ultimate efficiency, especially at lower speeds. The six-speed automatic transmission is smooth and refined, but its relatively limited number of gears compared to more modern eight- and ten-speed units contributes to the lower MPG figures. Highway driving, while more efficient, is still affected by the RC 350’s weight and all-wheel-drive system, which add parasitic losses.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2022 Lexus RC 350 AWD is $2,650. This figure is based on driving 15,000 miles per year and using national average fuel prices. Note that this is a standard calculation, and your actual fuel expenses will vary based on your driving habits, the type of fuel you use, and fuel prices in your area. However, it provides a benchmark for comparing the RC 350 to other vehicles. This figure is higher than alternatives, which may encourage some people to consider all Lexus fuel economy data.

Real-world expectations

The EPA provides a standardized testing methodology, but real-world fuel economy often differs. RC 350 owners often report achieving the EPA’s 26 MPG highway figure is realistic during steady cruising. However, aggressive driving, frequent acceleration, and stop-and-go traffic will reduce fuel economy. If your driving is primarily urban, expect to see numbers closer to the city rating, or even lower. The RC 350’s AWD system, which is beneficial in bad weather, also contributes to a slight fuel economy penalty compared to the rear-wheel-drive version.

How it compares

Compared to its competitors, the RC 350 AWD’s fuel economy is in the middle. The BMW 430i xDrive coupe, with its turbocharged four-cylinder engine, achieves a better 28 MPG combined. The Audi A5 Coupe Quattro also has a combined 28 MPG with its turbocharged four-cylinder. The Infiniti Q60 AWD, with its twin-turbo V6, is closer to the RC 350, rated at 22 MPG combined. The Mercedes-Benz C300 4MATIC Coupe, another turbocharged four-cylinder competitor, achieves around 26 MPG combined. Buyers in this segment often want a combination of luxury, performance, and style and are willing to accept a slight compromise in fuel economy for a specific driving experience. Anyone seriously considering an RC should also view the RC MPG across all years.

Tips to maximize efficiency

The RC 350 AWD isn’t especially fuel-efficient, but you can improve its MPG. Avoid aggressive acceleration and braking. The RC 350’s V6 is responsive, but frequently using its power will greatly impact fuel consumption. Maintain a steady speed on the highway and anticipate traffic flow to minimize unnecessary braking and acceleration.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, reducing fuel economy. Check your tire pressure regularly and inflate them to the manufacturer’s recommended specifications. Tire pressure fluctuates with temperature, so adjust accordingly.

Reduce unnecessary weight in the vehicle. Extra weight adds to the engine’s workload and consumes more fuel. Remove any items from the trunk or backseat that you don’t need to carry. Over time, this can make a small but measurable difference.

Use the “Eco” driving mode when appropriate. The RC 350 offers driving modes that alter the engine’s responsiveness and transmission mapping. The “Eco” mode prioritizes fuel efficiency by reducing throttle sensitivity and shifting to higher gears earlier. Use it during normal driving to conserve fuel.

Consider using cruise control on the highway. Cruise control helps maintain a consistent speed, which can improve fuel economy. However, be mindful of traffic and disengage cruise control when necessary to maintain a safe following distance.
