25 MPG combined isn’t going to win any hypermiling awards, but it’s a reasonable figure for the 2024 Lexus RC 300, considering it is a stylish and engaging coupe. This car isn’t primarily about saving fuel; it’s about delivering a premium driving experience with an emphasis on comfort and curb appeal. The RC 300 buyer knows this going in and accepts the fuel economy as a tradeoff for the overall package.

City and highway performance

The EPA estimates suggest a noticeable difference between city and highway fuel economy for the RC 300. The city rating of 21 MPG reflects the stop-and-go nature of urban driving, where the engine spends more time idling and accelerating. Conversely, the 31 MPG highway rating demonstrates the engine’s efficiency at a constant speed, aided by the eight-speed automatic transmission in finding the optimal gear. These figures highlight that the RC 300’s fuel consumption will vary significantly depending on driving conditions, rewarding those who spend more time on the open road.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Lexus RC 300 2.0L at $2,300. This figure is based on driving 15,000 miles per year, using national average fuel prices. It’s a useful benchmark for comparing running costs against other vehicles, but individual expenses will obviously vary depending on local fuel prices and personal driving habits. Consider this number a general guide, and factor in your own specific circumstances when budgeting for ownership.

Real-world expectations

Drivers should approach the EPA estimates as a guideline rather than a guarantee. Real-world fuel economy is affected by various factors, including driving style, road conditions, tire pressure, and even the use of air conditioning. Aggressive acceleration and frequent braking will inevitably reduce fuel efficiency, while smooth, steady driving can help to achieve or even slightly exceed the EPA numbers. Understanding these variables is key to maximizing fuel economy in your daily driving.

How it compares

The RC 300’s fuel economy lands it in a competitive set. The BMW 430i Coupe, similarly equipped with a 2.0L turbo engine, achieves a slightly better 28 MPG combined. Meanwhile, the Audi A5 Coupe, another direct competitor, also claims 28 MPG combined with its 2.0 TFSI engine. The Infiniti Q60, while offering more power, lags slightly behind with a combined 22 MPG. These comparisons illustrate where the RC 300 sits within its class, making it a reasonable choice but not class-leading in fuel efficiency. Understanding the RC MPG across all years helps to gauge its consistiency. Shoppers prioritize the RC 300’s unique blend of Lexus luxury, reliability, and distinctive styling, understanding the fuel economy is a trade-off but remaining acceptable within this segment.

Tips to maximize efficiency

The RC 300’s eight-speed automatic transmission is designed to optimize fuel economy, but it can be further enhanced by using the drive mode selector. The “Eco” mode alters throttle response and shift points to prioritize fuel conservation, a simple adjustment that can make a noticeable difference in daily driving, especially around town.

Proper tire inflation is critical for both safety and fuel economy. Check your tire pressures regularly and maintain them at the recommended levels, which can be found on the sticker inside the driver’s side doorjamb. Under-inflated tires increase rolling resistance, leading to higher fuel consumption.

Avoid unnecessary weight in the vehicle. Carrying around extra cargo increases the engine’s workload, negatively impacting fuel efficiency. Remove any items you don’t need, particularly heavy objects in the trunk, to lighten the load and improve gas mileage.

Smooth, consistent driving is key to maximizing MPG. Anticipate traffic flow, avoid aggressive acceleration and braking, and maintain a steady speed whenever possible. These techniques will reduce fuel consumption and also contribute to a more relaxed and enjoyable driving experience. Don’t consider using cruise control an autopilot system; be ready to de-activate it when road conditions warrant.

Regular maintenance, including oil changes and air filter replacements, ensures that the engine operates at peak efficiency. A well-maintained engine performs optimally, using less fuel to deliver the same level of performance. Refer to the owner’s manual for the recommended maintenance schedule. Owners should review all Lexus fuel economy data to stay well-informed, but the RC 300 buyer is typically seeking a unique experience, not purely top-tier MPG.
