What is the gas mileage on a Lexus rc300h?
In U.S. EPA testing, the Lexus RC 300h typically delivers around 40 miles per gallon (mpg) combined. Actual results vary by year, trim, and driving conditions.
The RC 300h is Lexus’s compact hybrid coupe, pairing a 2.5-liter Atkinson-cycle engine with electric motors. This setup is designed to balance efficiency with accessible performance, but real-world mileage depends on factors like climate control use, tire choice, and how you drive.
How the RC 300h achieves efficiency
The hybrid system uses a combination of gasoline power and electric propulsion, with regenerative braking to recover energy during deceleration. The Atkinson-cycle engine is optimized for fuel economy at typical daily speeds, while the electric motor assists during acceleration and helps shut the engine off when coasting or stopped.
EPA fuel economy by model year
Below is a snapshot of typical EPA estimates for the US market RC 300h models from its primary production years. These figures are used to compare efficiency across trims and are subject to testing cycle differences.
- US-market RC 300h (model years around 2013–2015): EPA-estimated about 40 mpg combined, with city/highway splits commonly cited in the high 30s to around 40 mpg depending on year and test cycle.
Note: The RC 300h was produced during a limited window and numbers can vary slightly by year and testing protocol. For a specific used-car purchase, check the official EPA label on the vehicle or the original window sticker for the exact rating.
Real-world performance and factors that affect mpg
Real-world mileage often diverges from EPA estimates due to driving style, weather, terrain, and accessory use. Hybrids typically perform best with smoother acceleration, steady cruising, and limited heavy loads. Cold weather, prolonged high-speed driving, and frequent use of climate control can reduce mpg.
- Driving style: gentler acceleration and gradual braking improve efficiency.
- Climate control and electronics: A/C use and heated seats can lower mpg, especially on hot or cold days.
- Tire condition and type: properly inflated, low-rolling-resistance tires help mpg.
- Maintenance: clean filters, proper oil, and a healthy hybrid battery keep the system efficient.
Tips to maximize fuel economy in the RC 300h
Owners looking to squeeze more miles per gallon can try the following practices.
- Use Eco or similar drive modes if available to optimize throttle response and climate control usage.
- Keep tires inflated to the recommended pressure and use fuel-efficient tires when possible.
- Plan trips to minimize stops and starts; combine errands to reduce overall idling and acceleration cycles.
- Maintain regular maintenance, including battery health checks and filter replacements, to sustain optimal hybrid performance.
Summary
The Lexus RC 300h offers roughly 40 mpg combined in U.S. EPA testing, with real-world results typically in the high 30s to about 40 mpg depending on conditions and year. As a used hybrid from a limited production window, mileage will vary by maintenance history and driving habits. For prospective buyers, checking the exact EPA rating on the specific vehicle and adopting efficient driving habits can help manage fuel costs.
How many miles per gallon does a Lexus 300h hybrid get?
The Lexus 300h hybrid model, specifically the ES 300h, has an EPA-estimated fuel economy of 44 MPG combined, with 43 MPG in the city and 44 MPG on the highway. This is achieved through a 2.5-liter four-cylinder engine combined with an electric motor, providing a smooth and efficient driving experience.

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.
How many miles per gallon does a Lexus RC 300 get?
The Lexus RC 300's fuel economy is 21 city / 31 highway / 25 combined MPG for the rear-wheel-drive (RWD) model, while the all-wheel-drive (AWD) version gets 19 city / 26 highway / 22 combined MPG. These figures can vary depending on factors like the model year, specific options, and driving conditions.
Rear-Wheel Drive (RWD)
- City: 21 MPG
- Highway: 31 MPG
- Combined: 25 MPG
All-Wheel Drive (AWD)
- City: 19 MPG
- Highway: 26 MPG
- Combined: 22 MPG
