Performance and Capability

First, the similarities in the RDX vs. QX55 comparison. Both the INFINITI QX55 and Acura RDX are powered by a turbocharged 2.0-liter inline four-cylinder engine.

The result is similar levels of power output, with the INFINITI QX55 generating 268 horsepower and 280 pound-feet of torque to the Acura RDX’s 272 horsepower and 280 pound-feet of torque.

In their standard or base editions, the new INFINITI QX55 and Acura RDX match each other in EPA-estimated fuel economy ratings. Both base models earn an EPA-estimated 22/28 MPG1 (City/Highway). However, there’s one key difference between the base editions of these luxury SUVs, and that’s their drive type.

To reach peak fuel economy ratings, the Acura RDX relies on front-wheel drive (FWD). The automaker’s all-wheel-drive system (AWD) is only optional on select versions of the SUV. INFINITI equips every new QX55 for sale with standard AWD, ensuring every QX55 driver has the grip and confidence to take on the road during more weather conditions.

When upgraded with AWD to match the INFINITI QX55, the Acura RDX SUV’s fuel economy dips below its competitor in both city and highway driving situations.

Both of these athletic luxury SUVs are offered with an optional trailer hitch receiver. However, these models are meant to tow light-duty items like bike racks or small trailers.

Cabin Dimensions and Versatility

If you’re shopping for a luxurious sport-ute like the new Acura RDX midsize SUV or the INFINITI QX55 luxury crossover coupe, you’re likely to upgrade to a vehicle that can accommodate plenty of passengers and cargo with ease. That calls for another INFINITI QX55 vs. Acura RDX comparison.

With its 110.2-inch wheelbase, the new INFINITI QX55 offers more length between the front and rear wheels than its competitor. This helps the new QX55 top the Acura RDX in second-row legroom and other crucial second-row dimensions. It’s all about comfort in the INFINITI luxury crossover coupe.

Regarding cargo volume, the Acura RDX narrowly edges out the INFINITI QX55, with 29.5 cubic feet of standard cargo capacity compared to 26.9 cubic feet. This is because the bold and stylish QX55 boasts a crossover coupe silhouette with a raked roofline that gives up a bit of cargo area height in favor of standout style.

Both models can carry up to five occupants in luxurious comfort. If you’d like to explore the QX55 vs. RDX interiors more closely, visit your local auto dealerships to get inside and experience these SUV models for yourself.
