23 MPG combined isn’t the main selling point of the 2022 Lexus RC 350. This stylish coupe appeals to drivers seeking a blend of luxury, sporty handling, and distinctive design, not necessarily record-breaking fuel efficiency. The RC 350 is for those who prioritize the experience of driving over squeezing every last mile from a gallon of premium fuel. It’s a statement car as much as a mode of transportation, and its fuel economy reflects that.

City and highway performance

The RC 350 achieves 20 MPG in the city and 28 MPG on the highway. The city figure is a product of stop-and-go traffic, where the 3.5L V6 engine works harder and the automatic transmission cycles frequently. Out on the open road, at a steady cruising speed, the RC 350’s fuel consumption improves significantly. While 28 MPG isn’t class-leading, it’s respectable for a naturally aspirated V6 powering a vehicle of this size. The eight-speed automatic transmission (S8) also plays a role, optimizing engine speed for both performance and efficiency depending on driving conditions.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2022 Lexus RC 350 is $2,500. This figure is based on driving 15,000 miles per year and using national average fuel prices for premium gasoline, which the RC 350 requires. Your actual fuel costs may vary depending on your driving habits, local fuel prices, and the amount you drive each year. This also assumes you adhere to the manufacturer’s recommendation of using premium fuel to maintain optimal performance and efficiency. Ignoring this recommendation could lead to lower fuel economy and potential engine issues in the long run.

Real-world expectations

While the EPA provides a standardized estimate, reality often differs. Aggressive driving, frequent short trips, and even tire inflation can all impact fuel economy. RC 350 owners who enjoy the V6’s power and frequently use the Sport driving mode will likely see figures closer to the city estimate, especially in combined driving. Conversely, those who prioritize smooth, consistent acceleration and spend more time on the highway might get closer to, or even slightly exceed, the 28 MPG highway rating. RC MPG across all years are available for comparison if you are interested in older models.

How it compares

In the realm of luxury coupes, the RC 350’s fuel economy sits roughly in the middle of the pack. The BMW 430i Coupe, with its turbocharged 2.0L four-cylinder engine, achieves a combined 28 MPG. The Audi A5 Coupe, also featuring a turbocharged 2.0L, gets an EPA-rated 27 MPG combined. The Infiniti Q60, equipped with a twin-turbo 3.0L V6, lands closer to the RC 350 at 22 MPG combined. The comparison matters because buyers considering the RC 350 often cross-shop these alternatives, weighing performance, luxury, and fuel costs. While the RC 350 might not win on fuel economy alone, it offers a distinct character and driving experience that sets it apart. See all Lexus fuel economy data on this site.

Tips to maximize efficiency

Avoid aggressive acceleration. The RC 350’s naturally aspirated V6 delivers smooth, linear power, but stomping on the accelerator will quickly deplete your fuel tank. Gentle acceleration and anticipating traffic flow can significantly improve your MPG. Use the normal drive mode in everyday driving.

Ensure your tires are properly inflated. Underinflated tires create more rolling resistance, forcing the engine to work harder and reducing fuel economy. Check your tire pressure regularly and inflate them to the recommended pressure listed on the driver’s side doorjamb. This is especially crucial for the RC 350, where maintaining optimal handling is part of the driving experience.

Reduce unnecessary weight. Carrying extra weight in your vehicle requires more energy to accelerate and maintain speed. Remove any unnecessary items from your trunk and passenger cabin to lighten the load and improve fuel economy. This is particularly relevant for a coupe like the RC 350, where available cargo space is already limited.

Consider using cruise control on highway drives. Maintaining a consistent speed can optimize fuel consumption, especially on long stretches of highway. The RC 350’s cruise control system helps maintain a steady pace, minimizing unnecessary acceleration and deceleration that can waste fuel.

Keep up with routine maintenance. A well-maintained engine runs more efficiently. Follow the manufacturer’s recommended maintenance schedule, including regular oil changes, air filter replacements, and spark plug inspections. Proper maintenance ensures the RC 350’s engine operates at its peak performance and fuel efficiency.
