How many miles per gallon does the RC 300h get?
The RC 300h typically delivers around 32 miles per gallon combined in standard driving, with EPA estimates generally hovering in the low- to mid-30s depending on model year and configuration.
The question reflects a common concern among luxury-hybrid buyers: how efficiently does a stylish two-door perform at the pump? The RC 300h uses a hybrid powertrain that blends gasoline and electric propulsion, aiming to balance performance with efficiency. Because the RC 300h was produced for a relatively brief period (primarily the 2013–2015 range in the U.S. market), official numbers can vary slightly by year, tire setup, and trim level. Real-world results also depend on how and where you drive, as with any hybrid.
What the EPA ratings typically show
EPA estimates for the RC 300h place its combined fuel economy in the low- to mid-30s miles per gallon range. In practice, many owners see numbers in the low 30s for mixed driving, with highway trips sometimes pushing toward the upper 30s under optimal conditions. The exact figure tends to be year- and model-specific, and can be affected by tire choice and driving style.
Real-world performance and expectations
In everyday use, front-seat drivers report that the RC 300h can feel peppier than a conventional luxury V6 when accelerating from stops, thanks to the electric assist. However, as traffic slows or climbs hills, mpg can dip below the EPA estimates. Conversely, steady highway cruising at moderate speeds typically yields better efficiency, sometimes approaching the higher end of the hybrid’s range.
What influences fuel economy the most
Several factors influence the RC 300h’s mpg in real life:
- Driving conditions: city versus highway, stop-and-go traffic versus steady speeds.
- Tire type and condition: low-rolling-resistance tires can improve efficiency, while worn tires can hurt it.
- Climate control usage: air conditioning and heating can reduce fuel economy, especially in extreme weather.
- Maintenance and battery health: a well-maintained hybrid system performs more efficiently.
Bottom line
For the Lexus RC 300h, you can expect about 32 mpg combined as a typical figure, with real-world results ranging in the low 30s to the upper 30s under favorable conditions. As with most hybrids, your mileage will hinge on how and where you drive, plus how well the vehicle is maintained.
Summary
The RC 300h offers a competitive blend of luxury and efficiency for its class, with EPA-oriented numbers in the low- to mid-30s mpg and real-world results that depend heavily on driving style and conditions. If fuel economy is a primary concern, monitoring driving habits and tire setup can yield the best possible numbers from this hybrid coupe.

44-46mpg
What is the real mpg of the Lexus NX300h?
Lexus NX300h ECONOMY AND EMISSIONS
Our actual real-life average after a week of driving the NX hybrid was 31.1mpg. The best we achieved with very gently driving was 39.4mpg.
What is the real world mpg for the Lexus RC?
Overall after a week of mixed driving we averaged 41.8mpg – which may be reasonable for a coupe, but is quite a way short of the official 56.5mpg average figure. So the RC's real-world economy isn't amazing – which is in part due to the fact that the electric driving range is very short.
