The 2020 Acura RDX AWD A-SPEC with the 2.0L 4-cylinder gets 23 MPG combined, a calculated compromise. It’s not the most efficient in its class, but it’s acceptable for a sporty, all-wheel-drive compact SUV for buyers who value driving dynamics and distinctive styling more than saving on gas. This is a vehicle bought for its sharper handling, premium features, and aggressive A-SPEC looks, and its fuel economy reflects that.

City and highway performance

EPA estimates of 21 MPG in the city and 26 MPG on the highway show moderately efficient driving. The city number suggests that stop-and-go traffic will noticeably decrease fuel economy, which is common with many turbocharged engines because maintaining boost pressures requires more fuel. The highway number is respectable, but not exceptional. Long road trips will likely require more frequent fuel stops than some competitors. The 10-speed automatic transmission helps keep the engine in its most efficient range, but the demands of all-wheel drive and the driver’s tendency to use the engine’s 272 horsepower will affect real-world results.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Acura RDX AWD A-SPEC at $2,500. This is based on driving 15,000 miles per year, using a national average fuel price. This gives potential buyers a metric to compare against other vehicles. While the RDX isn’t a gas guzzler, fuel costs can add up, especially if fuel prices increase or if the driver drives more aggressively, something this vehicle encourages.

Real-world expectations

While the EPA estimates provide a baseline, real-world MPG for the 2020 Acura RDX AWD A-SPEC will vary. Drivers who frequently use the “Sport” driving mode or want quick acceleration will likely see numbers closer to the city estimate, or even slightly below. However, those who drive more conservatively on the highway might achieve results closer to, or even slightly above, the 26 MPG estimate. Factors like tire pressure, vehicle load, and weather conditions will also affect fuel consumption. Examining RDX MPG across all years can provide more context.

How it compares

The RDX’s fuel economy is in the middle of its class. The BMW X3 xDrive30i also offers all-wheel drive and a turbocharged 2.0L engine, often getting a slightly better 24 MPG combined. The Lexus NX 300h hybrid, while less sporty, gets a much higher 31 MPG combined rating. Even the Volvo XC60 T5 AWD manages around 23 MPG combined, roughly matching the RDX. The Acura’s A-SPEC trim is a conscious styling and performance choice, and buyers who select it often accept the modest MPG penalty associated with AWD and a more aggressive driving style, valuing the vehicle’s aesthetic and handling. Be sure to see all Acura fuel economy data for a broader perspective.

Tips to maximize efficiency

Use the RDX’s “Comfort” or “Normal” driving modes during typical commutes. The “Sport” mode sharpens throttle response and enhances the driving experience, but it also increases fuel consumption.

Avoid using the turbocharger’s boost too much. Gentle acceleration and maintaining a steady speed will dramatically improve your MPG.

Make sure your tires are properly inflated. Underinflated tires increase rolling resistance, making the engine work harder and consume more fuel. Check your tire pressure regularly and inflate them to the recommended levels, found on a sticker inside the driver’s side doorjamb.

Remove unnecessary weight in the vehicle. Extra cargo weighs the vehicle down, requiring more energy to accelerate and maintain speed. Remove any items that you don’t need regularly, such as sporting equipment or tools.

Minimize idling time. If you anticipate waiting for more than a minute or two, turn off the engine. Idling consumes fuel without forward motion. Modern vehicles have efficient starters designed to handle frequent start-stop cycles.

Plan routes to avoid stop-and-go traffic when possible. Congested traffic reduces fuel economy. Use navigation systems and traffic apps to identify and avoid heavily congested areas. Choosing routes with fewer stops and starts can make a noticeable difference in overall MPG.
