How many miles per gallon does a 2015 RC 350 get?
The 2015 Lexus RC 350 typically achieves about 22 miles per gallon (mpg) combined in rear-wheel-drive (RWD) form and around 21 mpg in all-wheel-drive (AWD) form, with roughly 19 mpg in the city and 28 mpg on the highway for RWD, and about 19 mpg city / 26 mpg highway for AWD.
These figures come from official EPA estimates and apply to the standard RC 350 with a 3.5-liter V6 and an 8-speed automatic transmission. Real-world results vary depending on driving conditions, tire setup, maintenance, and individual driving style.
EPA fuel economy by drivetrain
Official EPA estimates are broken out by drivetrain. The figures below reflect typical ratings for the 2015 RC 350.
- Rear-wheel drive (RWD): City 19 mpg, Highway 28 mpg, Combined 22 mpg
- All-wheel drive (AWD): City 19 mpg, Highway 26 mpg, Combined 21 mpg
In practice, a driver may see values slightly above or below these figures depending on factors such as traffic conditions, climate, and how aggressively the car is driven.
Real-world mpg factors
Several elements can influence actual fuel economy beyond the EPA numbers.
- Driving style: smoother acceleration and efforts to minimize hard braking typically improve mpg.
- Tire type and condition: low-rolling-resistance tires and properly inflated tires help maximize efficiency; worn or high-rolling-resistance tires can reduce it.
- Vehicle load and aerodynamics: extra weight and roof carriers increase drag and reduce mpg.
- Maintenance: clean air filters, proper oil changes, and timely spark plug replacement support better fuel economy.
- Climate and terrain: city driving, hills, and extreme temperatures generally lower mpg compared with steady highway driving in moderate conditions.
Tips to maximize mpg include driving calmly, keeping tires properly inflated, and performing regular maintenance as recommended by Lexus.
Summary
For the 2015 RC 350, expect about 22 mpg combined in the RWD configuration and about 21 mpg combined in AWD, with city ratings near 19 mpg and highway ratings around 28 mpg (RWD) or 26 mpg (AWD). Real-world mileage depends on driving habits, tire setup, and other conditions.
