The 2023 Lexus RC 300 AWD’s 22 MPG combined rating will not attract drivers looking for the most fuel-efficient car. That’s ok, this isn’t the target audience. It’s a stylish, comfortable all-weather coupe with a naturally aspirated V6, prioritizing a smooth, engaging driving experience. The RC 300 AWD appeals to drivers who appreciate refined power delivery and the security of all-wheel drive, even if it means spending more on gas.
City and highway performance
The EPA estimates the RC 300 AWD at 19 MPG in the city and 26 MPG on the highway. The city figure reflects stop-and-go traffic, where the engine spends more time idling and accelerating. The highway number, while not exceptional, is respectable, suggesting the RC 300 AWD cruises efficiently at higher speeds thanks to its well-tuned six-speed automatic transmission. Drivers sticking to mostly highway miles will see fuel economy numbers closer to that 26 MPG rating.
Annual fuel cost
According to the EPA, the estimated annual fuel cost for the 2023 Lexus RC 300 AWD is $2,650. This is based on driving 15,000 miles per year and national average fuel prices. Your actual fuel costs will vary depending on your driving habits, the type of fuel you use, and where you live, as fuel prices fluctuate regionally. However, it provides a useful benchmark for comparing the RC 300 AWD’s running costs to other vehicles. Before deciding to buy, prospective owners should review all Lexus fuel economy data.
Real-world expectations
While the EPA estimates are a good starting point, real-world fuel economy can differ. Aggressive driving, frequent short trips, and cold weather all negatively impact your MPG. However, gentle acceleration, consistent highway speeds, and proper vehicle maintenance can help you achieve numbers closer to, or even slightly exceeding, the EPA estimates. Online owner forums and fuel tracking apps provide valuable insights into what other RC 300 AWD drivers are experiencing in similar conditions.
How it compares
Among luxury coupes with all-wheel drive, the RC 300 AWD’s fuel economy is in the middle. The BMW 430i xDrive, with its 2.0L turbocharged four-cylinder, achieves a combined EPA rating of 28 MPG, seeking greater fuel efficiency. The Infiniti Q60 AWD, powered by a 3.0L twin-turbo V6, lands at around 22 MPG combined, similar to the RC 300 AWD. The Audi A5 Coupe quattro, featuring a 2.0L turbocharged four-cylinder engine, manages 27 MPG combined. These differences matter to buyers potentially cross-shopping these vehicles, especially those who want to save more on gas to offset the higher upfront costs of a luxury vehicle. Drivers concerned about long-term cost of ownership may also wish to review RC MPG across all years to see how efficiency has trended over time.
Tips to maximize efficiency
The RC 300 AWD benefits from smooth and measured acceleration. The naturally aspirated V6 responds well to gentle throttle inputs, and avoiding aggressive starts will noticeably improve fuel economy, especially in city driving. Let the engine’s torque do the work, rather than constantly pushing the engine to higher RPMs.
Regular maintenance is important for optimal fuel efficiency. Ensure your tires are properly inflated to the recommended pressure, as underinflated tires create more rolling resistance. Keep up with scheduled oil changes and air filter replacements, as these seemingly small tasks can affect your MPG.
While you might want to use the RC 300 AWD’s paddle shifters and sport mode often, try to limit their use when fuel economy is a priority. The vehicle’s standard drive mode and automatic transmission are programmed to optimize fuel efficiency, and manually downshifting or engaging sport mode will lead to higher RPMs and increased fuel consumption.
Reduce unnecessary weight in your vehicle. Carrying extra cargo increases the amount of energy required to accelerate and maintain speed. Remove non-essential items from the trunk and passenger area to lighten the load and improve fuel efficiency.
