The 2019 Acura RDX AWD A-SPEC’s 23 MPG combined represents a reasonable trade-off. It’s not a fuel-sipping hybrid; it’s a sporty crossover with advanced technology, designed to deliver a premium driving experience and eye-catching style, especially in A-SPEC trim. Buyers attracted to the RDX A-SPEC likely prioritize sharp handling, distinctive styling, and abundant features over ultimate fuel efficiency. They accept the fuel consumption as part of the total package.

City and highway performance

The EPA estimates for the 2019 RDX AWD A-SPEC break down to 21 MPG in the city and 26 MPG on the highway. The city figure reflects the demands of stop-and-go traffic, where the 2.0L turbocharged engine works a bit harder. The highway number is more appealing, showcasing the engine’s efficiency at steady cruising speeds. While 26 MPG isn’t class-leading, it’s a respectable figure for a vehicle with standard all-wheel drive and a curb weight around 4,000 pounds.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,500 for the 2019 Acura RDX AWD A-SPEC 2.0L 4-cyl. This figure is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs will depend on your driving habits, the type of fuel you use, and your local gas prices. Aggressive driving will certainly increase this number, while more conservative driving could decrease it slightly.

Real-world expectations

EPA estimates provide a useful baseline, but real-world fuel economy often differs. Some RDX owners report average MPG figures close to the EPA’s combined rating. However, variances are common. Drivers who primarily drive in congested urban environments might see figures closer to the 21 MPG city estimate. Those who frequently embark on longer highway journeys could potentially exceed the 26 MPG highway figure, particularly when using cruise control and maintaining a steady speed. Weather conditions, tire pressure, and cargo weight can also influence fuel consumption.

How it compares

Compared to rivals, the 2019 Acura RDX A-SPEC AWD’s fuel economy lands in the middle of the pack. The Lexus NX 300 AWD, for instance, achieves a slightly better 24 MPG combined. However, the NX prioritizes comfort and refinement over sporty handling, which might not appeal to the RDX buyer. The BMW X3 xDrive30i, another popular competitor, also achieves 24 MPG combined. The Audi Q5 45 TFSI quattro offers similar fuel economy at 24 MPG combined as well, but the RDX A-SPEC counters with its more aggressive styling and potentially lower price point.

Tips to maximize efficiency

Use the RDX’s drive mode selector. The “Econ” mode prioritizes fuel efficiency by adjusting throttle response and transmission mapping. This can be useful for city driving or when cruising on the highway. Switching to “Sport” mode transforms the driving experience, but it will also significantly impact fuel economy.

Maintain proper tire inflation. Under-inflated tires increase rolling resistance, forcing the engine to work harder and consuming more fuel. Consult the sticker on your driver’s side doorjamb for the recommended tire pressure, and check your tires regularly, especially during temperature fluctuations.

Avoid excessive idling. Modern vehicles, including the RDX, don’t require extended warm-up periods. Idling for more than a minute or two wastes fuel and contributes to emissions. If you anticipate a longer wait, turn off the engine.

Drive smoothly and avoid aggressive acceleration and braking. The RDX’s turbocharged engine responds well to gradual inputs. Hard acceleration burns fuel, and abrupt braking wastes energy. Anticipate traffic flow and maintain a steady speed when possible.

Lighten the load. Carrying unnecessary weight in your vehicle reduces fuel economy. Remove items from your trunk or cargo area that you don’t need regularly. The less weight the engine has to haul around, the more efficient it will be.
