The 2017 Acura RDX AWD with the 3.5L V6 gets 22 MPG combined, which isn’t class-leading, but it’s a reasonable balance for buyers wanting smooth power delivery, Acura’s reputation for reliability, and the added traction of all-wheel drive in a compact luxury SUV. This isn’t a hybrid, or a fuel-sipping diesel. It’s a traditionally engineered vehicle designed for a specific driving experience.

City and Highway Performance

The EPA estimates 19 MPG in the city and 27 MPG on the highway. The city figure reflects stop-and-go driving, where the RDX’s 3.5L V6 isn’t at its most efficient. The six-speed automatic transmission, while smooth, lacks the gear count of some newer competitors, which contributes to the lower city MPG. On the open road, the 27 MPG highway figure is more respectable, allowing for comfortable cruising and decent range between fill-ups. Expect that number to drop if you frequently engage the all-wheel-drive system on wintery roads, or push the engine hard.

Annual Fuel Cost

The EPA calculates the annual fuel cost for the 2017 Acura RDX AWD at $2,650. This figure is based on driving 15,000 miles per year, and using the national average fuel price. Remember that your actual fuel costs will vary depending on your driving habits, the type of fuel you use, and local gas prices. Drivers who drive predominantly in the city, or have a heavy foot, will likely exceed this estimate. This is an EPA estimate and your actual fuel expenditure might vary.

Real-World Expectations

EPA estimates provide a baseline, but real-world fuel economy often differs. Many RDX owners report figures modestly below the EPA’s combined rating, particularly in areas with hilly terrain or frequent traffic congestion. However, some drivers who prioritize fuel-efficient driving techniques, and spend more time on the highway, can achieve figures closer to, or even slightly above, the EPA’s highway estimate. The key is to adopt a smooth, consistent driving style, and avoid aggressive acceleration when possible.

How It Compares

The 2017 Acura RDX’s fuel economy is in the middle of its competitors. A 2017 Lexus NX 200t, with its turbocharged four-cylinder, offers slightly better combined fuel economy at 25 MPG, prioritizing efficiency over the RDX’s more reliable V6 power. The Audi Q5 from the same year, equipped with its 2.0T engine, also manages around 23 MPG combined. However, these competitors may not offer the same level of power, or the naturally aspirated smoothness that many RDX buyers appreciate. Ultimately, the RDX buyer accepts a trade-off: strong, reliable power for a few lost MPGs. You can view RDX MPG across all years on our site.

Tips to Maximize Efficiency

Avoid aggressive acceleration. The RDX’s V6 is responsive, but stomping on the gas pedal frequently will significantly reduce fuel economy. Gentle acceleration and smooth transitions will help you stay closer to the EPA estimates.

Maintain proper tire inflation. Underinflated tires create more rolling resistance, which reduces fuel efficiency. Check your tire pressure regularly, and inflate them to the recommended pressure, which is usually found on a sticker inside the driver’s side doorjamb. This also helps with tire wear.

Reduce unnecessary weight. Carrying extra weight in your vehicle, such as tools or sporting equipment, that you don’t regularly use, increases fuel consumption. Lighten the load, and remove any unnecessary items from your RDX.

Use cruise control on the highway. Maintaining a consistent speed helps optimize fuel efficiency on long stretches of highway. Cruise control can help you avoid unintentional speed fluctuations that waste fuel.

Consider using premium fuel. While the RDX doesn’t require premium fuel, some drivers report a slight improvement in performance and fuel economy when using it. Experiment to see if it makes a difference for your driving style and typical routes, or consult all Acura fuel economy data.
