The 2023 Acura RDX AWD A-SPEC 2.0L 4-cyl gets 23 MPG combined. It’s a figure that might make some pause, especially in a segment increasingly populated by hybrid and even fully electric options. The RDX A-SPEC isn’t chasing ultimate efficiency. It’s chasing a different kind of customer: one who prioritizes sporty handling, distinctive styling, and a premium experience, and is willing to accept middling fuel economy as the price of admission.

City and highway performance

The EPA estimates of 21 MPG in the city and 26 MPG on the highway highlight the RDX’s strengths and weaknesses. The in-town figure reflects the realities of stop-and-go driving, where the 2.0L turbocharged engine works harder to overcome the vehicle’s nearly 4,100-pound curb weight. The ten-speed automatic transmission, while generally smooth and responsive, can sometimes hunt for the right gear in these conditions, further impacting efficiency. On the open road, however, the RDX fares better. The turbocharger allows for relaxed cruising at highway speeds, and the transmission settles into higher gears, allowing the engine to sip fuel more sparingly. It won’t win any hypermiling contests, but 26 MPG is respectable for a non-hybrid crossover with all-wheel drive.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Acura RDX AWD A-SPEC at $2,500. This calculation is based on driving 15,000 miles per year, using the EPA’s combined MPG rating, and factoring in national average fuel prices. It’s a sobering number, especially for buyers accustomed to more frugal vehicles. It places the RDX A-SPEC squarely in the range of vehicles that require a decent fuel budget. Prospective buyers need to realistically assess their driving habits and consider whether this cost aligns with their financial expectations. Don’t forget to check recent gas prices, as fuel costs can vary significantly.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy can vary considerably depending on driving style, road conditions, and even the weather. Aggressive acceleration, frequent hard braking, and extended idling will all negatively impact fuel efficiency. Similarly, driving in hilly terrain or against strong headwinds will also increase fuel consumption. Owners who prioritize fuel economy and adopt more conservative driving habits can likely achieve figures closer to the EPA’s estimates, while those with a heavier foot may find themselves falling short. Tires, spark plugs, and engine air filter condition will also impact fuel economy. Check RDX MPG across all years to see how older models perform in real world conditions.

How it compares

The RDX A-SPEC’s fuel economy places it in the middle of the pack within its competitive set. The Lexus NX 350h, a hybrid, delivers significantly better fuel economy, achieving an EPA-estimated 39 MPG combined. The BMW X3 sDrive30i, with its rear-wheel drive configuration and slightly less powerful engine, manages around 25 MPG combined, a slight edge but still a difference. The Audi Q5 45 TFSI Quattro also hovers around the 25 MPG combined mark. These small differences can add up over time. For buyers prioritizing fuel efficiency, hybrid options like the NX are a good choice. But for those who value the RDX’s sharper handling and more aggressive styling, the trade-off in MPG may be acceptable. Review all Acura fuel economy data for more information.

Tips to maximize efficiency

Take advantage of the RDX’s drive mode selector. The “Comfort” mode prioritizes fuel efficiency by optimizing throttle response and shift points. While “Sport” mode is tempting, it can lead to more aggressive driving and decreased MPG. Being mindful of your drive mode can provide a small fuel economy increase.

Maintain proper tire inflation. Underinflated tires increase rolling resistance and negatively impact fuel economy. Check your tire pressure regularly and inflate your tires to the recommended pressure listed on the driver’s side doorjamb. This is a simple task you can do at home with a tire pressure gauge and an air compressor.

Minimize idling. Letting your engine idle for extended periods wastes fuel. If you anticipate stopping for more than a minute, turn off the engine. The RDX doesn’t have automatic start-stop, so it requires some effort from the driver to adopt this habit. Also, try to keep cargo weight to a minimum.

Avoid aggressive driving. Rapid acceleration, hard braking, and excessive speeding all consume more fuel. Adopt a smoother, more gradual driving style to improve your fuel economy. Anticipate traffic flow and avoid unnecessary lane changes.

Consider using premium fuel. While the RDX doesn’t require premium fuel, some owners have reported a slight improvement in fuel economy when using it. Experiment with a few tanks of premium fuel and see if you notice a difference. If not, stick with regular unleaded.
