24 MPG combined isn’t going to set the world on fire, but for the 2020 Lexus RC 300’s 2.0L turbocharged four-cylinder variant, it’s an acceptable exchange for the style and driving experience. This car prioritizes curb appeal and a connected feel over ultimate frugality. It’s a choice that many RC buyers consciously make.

City and highway performance

The 2020 RC 300 2.0L achieves an EPA-estimated 21 MPG in the city and 30 MPG on the highway. The city figure reflects the realities of stop-and-go driving, something this turbocharged engine copes with reasonably well thanks to its broad torque curve. The eight-speed automatic transmission helps keep the engine in its sweet spot, but aggressive acceleration will quickly drop that number. On the open road, the RC 300 shines, delivering a comfortable and relatively efficient experience for long-distance cruising. A lighter foot on the accelerator is key to maximizing that 30 MPG highway rating.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2020 Lexus RC 300 2.0L is $2,400. This figure is based on driving 15,000 miles per year and using national average fuel prices. Your individual fuel costs will vary depending on your driving habits, the type of fuel you purchase, and local gas prices. Lead-footed drivers will see that number climb quickly, while those who prioritize fuel efficiency can likely improve upon it. This $2,400 figure provides a useful benchmark, allowing potential buyers to consider fuel costs alongside other ownership expenses, like insurance and maintenance.

Real-world expectations

While the EPA figures provide a standardized comparison, real-world fuel economy often deviates. Some RC 300 drivers report seeing figures slightly below the EPA’s 24 MPG combined, particularly if their driving is predominantly in the city or involves frequent bursts of acceleration. However, those who prioritize smooth acceleration, anticipate traffic, and use cruise control on the highway often report achieving numbers closer to, or even slightly above, the EPA estimates. The car’s eagerness to rev and responsive throttle can tempt drivers to dip into the boost more often than necessary, impacting fuel economy. How you drive an Lexus matters.

How it compares

The 2020 RC 300’s fuel economy places it in the middle of its competitive set. The BMW 430i, for example, has a similar turbocharged four-cylinder engine and achieves an EPA-estimated 25 MPG combined. The Audi A5 Coupe, with its 2.0-liter TFSI engine, also returns around 27 MPG combined. The Infiniti Q60, with its turbocharged V6, sees a significant drop to around 22 MPG combined, highlighting the fuel consumption penalty for opting for more power. For buyers considering the RC, the slightly lower MPG figure might be offset by the Lexus’s reputation for reliability and lower overall running costs. Be sure to check the RC MPG across all years before making a decision.

Tips to maximize efficiency

Use the RC 300’s drive modes. Selecting “Eco” mode will remap the throttle response and shift points to prioritize fuel efficiency, encouraging a more relaxed driving style. While it might dull the initial acceleration, it can improve MPG, particularly in city driving.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and wasting fuel. Regularly check your tire pressure and inflate them to the pressures listed on the door jamb sticker. Proper tire inflation improves handling and extends tire lifespan too.

Avoid unnecessary idling. Modern engines are designed to be efficient when running, and prolonged idling wastes fuel. If you’re stopped for more than a minute or two, it’s more efficient to turn the engine off. This is especially relevant in urban areas with frequent stoplights or traffic jams.

Practice smooth acceleration and braking. Aggressive acceleration and hard braking consume significantly more fuel than gentle driving. Anticipate traffic flow, maintain a safe following distance, and avoid sudden bursts of speed or abrupt stops. Smooth and predictable driving is the key to squeezing every last mile out of each gallon.

Consider the weight you’re carrying. Excess weight in the vehicle increases fuel consumption. Remove any unnecessary items from the trunk and passenger areas to reduce the load on the engine. Every little bit helps, especially during city driving where you’re constantly accelerating and decelerating.
