28 MPG combined is not a headline-grabbing figure, but it is a perfectly respectable number for the 2020 Acura RLX Hybrid. This isn’t a dedicated fuel sipper designed to squeeze every last mile from a gallon. This is a luxury sedan prioritizing a smooth, comfortable ride and confident acceleration, qualities the RLX Hybrid delivers. The fuel economy, while not class-leading, is a worthwhile trade-off for the relaxed and refined driving experience offered by its unique hybrid powertrain.

City and highway performance

The RLX Hybrid’s EPA ratings showcase an unusual characteristic: its city MPG (28) is nearly identical to its highway MPG (29). This shows the car’s hybrid system is good at capturing energy and supplementing the gasoline engine in stop-and-go conditions. Many hybrids thrive in city driving and then their MPG drops on the highway, but the RLX Hybrid’s balanced performance suggests the electric motors and regenerative braking provide meaningful assistance across various driving scenarios. This consistency is a benefit for those who split their time evenly between urban commutes and longer freeway journeys, ensuring a stable fuel bill regardless of environment. The 3.5L 6-cyl engine provides strong performance for highway passing and merging.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Acura RLX Hybrid at $2,050. This figure is calculated based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs will vary depending on your driving habits and where you live. If you drive aggressively, or if fuel is particularly expensive in your area, you’ll likely spend more. If you drive fewer miles or are gentle on the accelerator, you could save money. This $2,050 figure provides a standardized benchmark for comparison against other vehicles.

Real-world expectations

EPA estimates are helpful, but real-world fuel economy invariably differs. RLX Hybrid owners often report MPG figures that hover around the EPA’s estimates, so 28 MPG combined is generally achievable if you drive reasonably. Aggressive driving, frequent hard acceleration, and consistently exceeding posted speed limits will all negatively impact fuel economy. However, the RLX Hybrid’s powertrain is generally forgiving, allowing drivers to enjoy brisk performance without a drastic MPG penalty. The consistent city/highway split further reinforces the reliability of the EPA figures for this car.

How it compares

The RLX Hybrid operates in a competitive segment. The Lexus ES 300h, for instance, achieves an impressive 44 MPG combined. However, the Lexus prioritizes fuel efficiency, while the Acura delivers more horsepower. The BMW 530e, a plug-in hybrid, offers a different approach, allowing for limited all-electric driving range and a combined MPG of 27. The Volvo S90 T8 Recharge, another plug-in hybrid, offers similar electric range as the BMW but with higher horsepower and a 30 MPG combined rating. All of these competitors beat the RLX in MPG, even if only marginally. Prospective buyers need to decide where their priorities lie: maximum fuel savings or overall driving experience.

Tips to maximize efficiency

One of the most effective ways to boost fuel economy in the RLX Hybrid is to accelerate and brake smoothly. Avoid sudden stomps on the pedals, and instead, gradually increase speed. This allows the hybrid system to operate more efficiently, using electric power to supplement the gasoline engine whenever possible. Gentle acceleration enables the car to stay in electric mode longer, especially at lower speeds.

Take advantage of the RLX Hybrid’s regenerative braking system. Anticipate stops and gently apply the brakes, allowing the system to capture kinetic energy and recharge the battery. This improves fuel efficiency and extends the life of your brake pads. Avoid hard braking unless necessary, as this reduces the amount of energy that can be recovered.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly and inflate them to the recommended pressure listed on the sticker inside the driver’s side doorjamb. Maintaining proper tire pressure is a simple way to improve your RLX Hybrid’s MPG.

Reduce unnecessary weight in the vehicle. Carrying extra cargo adds to the vehicle’s load, requiring more energy to accelerate and maintain speed. Remove any items you don’t need from the trunk and rear seats to minimize weight and improve fuel economy. You can also compare RLX MPG across all years.
