23 MPG combined. Those three digits represent the reasonable compromise Acura RDX buyers make for a smooth, powerful V6 engine in a compact luxury crossover. This isn’t a hybrid or a hyper-efficient diesel; it’s a classically-engineered Acura built for confident acceleration and comfortable cruising. The fuel economy is simply part of the package, acceptable for the target audience but certainly not the primary reason they choose this particular vehicle.

City and highway performance

The EPA estimates 20 MPG in the city and 28 MPG on the highway for the 2017 Acura RDX with front-wheel drive and the 3.5L V6. The city figure reflects the realities of stop-and-go driving, where the engine spends more time idling or accelerating from a standstill. The highway number showcases the engine’s efficiency at a constant speed, taking advantage of the six-speed automatic transmission’s ability to select an optimal gear for cruising. The RDX isn’t built to be a champion in tight urban environments, it’s built for longer commutes and weekend getaways where that V6 can stretch its legs. Drivers who prioritize urban fuel efficiency above all else might consider other options.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2017 Acura RDX FWD is $2,500. This figure is based on driving 15,000 miles per year with a fuel price reflecting national averages at the time of calculation. Your actual fuel cost will vary depending on how much you drive, the type of driving you do, and the prevailing fuel prices in your area. While $2,500 might seem high compared to smaller, hybrid vehicles, it’s a reasonable cost for the level of performance and luxury the RDX provides.

Real-world expectations

The EPA provides a standardized test, but real-world fuel economy often differs. RDX drivers report figures that vary slightly from the official numbers. Those who primarily drive in the city might see closer to 18-19 MPG, while those who spend most of their time on the highway could achieve 29-30 MPG. Aggressive driving habits, heavy loads, and even tire pressure can all impact fuel consumption. The EPA estimates are benchmarks, not guarantees. See RDX MPG across all years.

How it compares

The 2017 Acura RDX’s fuel economy sits in an interesting position within the compact luxury crossover segment. The Lexus NX 300h, a hybrid, delivers a combined 31 MPG, offering a significant advantage in fuel efficiency. However, the NX prioritizes less gas over outright performance, which is not the target consumer for the Acura RDX. A non-hybrid Lexus NX 300 gets only 25 MPG combined. The BMW X3 xDrive28i, with its turbocharged four-cylinder engine, achieves a combined 24 MPG, slightly better than the RDX, but might not offer the same smooth power delivery that Acura buyers appreciate. The Audi Q5 with its turbocharged four-cylinder gets 25 MPG too.

Ultimately, the RDX buyer is weighing power and luxury against fuel economy. They’re willing to accept slightly lower MPG for the V6 experience and Acura’s reputation for reliability. Other Acura models have different aims; see all Acura fuel economy data.

Tips to maximize efficiency

Take advantage of the RDX’s “Econ” mode. This setting adjusts the throttle response and climate control system to give priority to fuel efficiency. It might slightly reduce performance, but it can make a noticeable difference, especially during city driving. It’s a simple way to improve fuel economy without drastically altering your driving habits.

Ensure your tires are properly inflated to the recommended pressure. Underinflated tires increase rolling resistance, which forces the engine to work harder and consume more fuel. Check your tire pressure regularly, especially during temperature changes, as this can affect inflation levels. Correct tire pressure not only improves fuel economy but also enhances handling and tire life.

Avoid aggressive acceleration and braking. Smooth, gradual inputs are key to maximizing fuel efficiency. Anticipate traffic flow and maintain a steady speed whenever possible. Rapid acceleration and hard braking waste fuel and put unnecessary strain on the engine and brakes.

Consider using cruise control on the highway to maintain a consistent speed. Cruise control can help prevent unintentional speed fluctuations, which can negatively impact fuel economy. Be mindful of traffic conditions and disengage cruise control when necessary.

Reduce unnecessary weight in the vehicle. Carrying extra cargo adds weight, which reduces fuel efficiency. Remove any items you don’t need, such as sporting equipment, tools, or other bulky items. Every pound counts, so lighten the load to improve MPG.
