The 2021 Acura RDX VS The Competition

A Side-By-Side Comparison - See Why the 2021 Acura RDX Dominates the Competition

With impeccable Acura craftsmanship and comfortable, spacious seating for five people, it's easy to see why drivers from Denver to Aurora, CO prefer the 2021 Acura RDX when the time comes to choose a new luxury SUV. At Mile High Acura, where this model is one of the most popular styles we carry, we know you have options, but we're here to explain everything that sets our luxury SUV apart from the similarly sized competition.

Acura RDX vs Lexus NX

Acura RDX

Lexus NX 300

  • Power. When it comes to getting you safely up to highway speeds and delivering a responsive, smooth level of performance that drivers love, the 2021 Acura RDX comes out ahead of the similar model from Lexus. While the Lexus NX offers various powertrains depending on the trim variation you choose, none are equal to the power and output from the Acura. Every 2021 Acura RDX gets its standard power from a 272-horsepower turbocharged four-cylinder engine, while the Lexus models start with just 203 horsepower from their base option, the Lexus NX 250. Stepping up to the Lexus NX 300 will increase power to 235 horsepower, but it's still not enough to overpower the Acura SUV.
  • Cargo. Whether you enjoy camping, shopping, or golfing, the Acura RDX can help you do more of what makes you happy. With the Lexus NX, you can expect a cargo hold of just 17.7 cubic feet behind the backseats. But with the 2021 Acura RDX, rear cargo space expands to a nice 31.1 cubic feet.
  • Space. Not only does the 2021 Acura RDX give you more space for your gear than the Lexus NX, but it also has more space for your passengers to stretch out in than the Lexus. Look for extra headroom, shoulder room, rear seat elbow room, and backseat legroom in our Acura model when compared next to the Lexus.

Acura RDX vs Infinity QX 50

  • Seating. Long road trips across country or short jaunts across Centennial, CO, both are easy and comfortable with the 2021 Acura RDX by your side. In two rows for five people, you can look forward to more space to stretch your legs in the Acura model over the INFINITI QX50. In fact, our SUV has more than two inches of extra front seat legroom, and more backseat legroom, than the competing SUV has.
  • Features. From safety features to technology, the 2021 Acura RDX also has more of the amenities that Littleton, CO drivers are looking for than the competition. For example, in terms of safety engineering, every Acura model in this collection gets standard adaptive cruise control, while the INFINITI does not. Additionally, our Acura SUV gets standard heated front seats across the lineup, which is only listed as an option for the QX50.
  • Performance. Finally, look for more power and engaging performance out of the 2021 Acura RDX compared to the INFINITI QX50. While both have standard power from a turbocharged 2.0-liter four-cylinder engine, the 2021 Acura RDX has 272 horsepower and 280 pound-feet of torque. The QX50 tops out at 268 horsepower. Additionally, where the INFINITI gets a standard continuously variable automatic transmission, the Acura model gets a smooth 10-speed automatic.

Acura RDX vs BMW X3

Power. Both the Acura RDX and the BMW X3 have willing engines with plenty of zip, but the RDX has more standard horsepower. Aurora, CO drivers will like that the RDX comes standard with a 272-horsepower turbocharged four-cylinder engine. The X3's four-cylinder base engine only produces 248 horsepower.

Ride Quality. While these two SUVs both have precise handling, the Acura RDX has a more comfortable ride. Its well-tuned suspension mops up road blemishes with ease for a silky-soft ride - even on rough streets in Denver. The BMW X3 rides smoothly in most situations, but it can become jittery on uneven pavement.


Cabin Quality. Since the Acura RDX and the BMW X3 are both luxury SUVs, they both have refined interiors with lavish materials. But people in Aurora, CO will appreciate that the RDX has an edgy, well-built cabin with sportier features than most of its rivals. The X3 has a nice interior, but its somewhat reserved next to the RDX.

Safety Features. The Acura RDX comes standard with eight advanced active safety features, while the BMW X3 has seven. Cautious Denver drivers will like that the RDX earned Top Safety Pick+ honors from the Insurance Institute for Highway Safety, including a Good rating for how well its headlights illuminate the road ahead. The X3 did well in most federal testing, but it received the second-lowest rating of Marginal for how well its standard headlights illuminate the road.

Despite being a better-known brand, the BMW X3 doesn't match the interior quality, standard horsepower, or safety features of the Acura RDX, despite having a higher sticker price. Visit Mile High Acura and test drive the RDX today.

Acura RDX vs Audi Q5

Audi Q5


  • More athletic handling. The new Acura RDX is a blast to drive on winding roads in Aurora, CO. Its precise steering and Integrated Dynamics System keep it poised and composed around turns. The new Audi Q5 also has a comfortable ride, but a lack of feedback from the pavement prevents it from feeling very sporty.
  • More standard horsepower. The new Acura RDX comes with a 272-horsepower turbocharged inline-four-cylinder engine that gives it plenty of oomph for merging onto the freeway in Denver. The new Audi Q5's base engine only puts out 261 horsepower. A stronger motor is available in the Audi SQ5, but you'd have to pay more for this high-performance variant.
  • Interior

    • More cargo space. If you typically load up your SUV with shopping bags from Denver stores, the new Acura RDX has more room for them. It has up to 58.9 cubic feet of cargo space when its back seats are folded. The new Audi Q5 only has 54 cubic feet of total cargo space.
    • More front legroom. You'll have more room to stretch out and relax in the new Acura RDX, which has 42 inches of front legroom. The Audi Q5 has just 40.9 inches of front legroom.
    • Wireless smartphone integration. Aurora, CO drivers will appreciate that the new Acura RDX comes standard with wireless Apple CarPlay and Android Auto connectivity as well as Amazon Alexa integration. The new Audi Q5 comes with wireless Apple CarPlay, but wireless Android Auto and Amazon Alexa are not available.

    The Audi brand name may have more panache, but the new Acura RDX gives Denver drivers more of what they want in a small luxury SUV. It also comes at a much lower starting price than the Audi Q5.

Acura RDX vs Lexus RX 350

Lexus RX 350

  • Performance.

Whether you're trying to drive in harsh road conditions or brave the toughest of trails in the Denver area, you want as much versatility as you can get out of your SUV. In both these vehicles, you'll get just that. But the Lexus RX 350 only comes with an eight-speed automatic transmission, and while this works just fine, the Acura RDX comes with an impressive 10-speed automatic, allowing for even better handling.       

  • Cargo.

When you buy an SUV, one expectation is that you'll be getting increased cargo room. While both vehicles offer that, the Lexus RX 350 only provides 16-cubic feet of space and double when the rear seats are folded down. But with Acura RDX, Aurora, CO drivers will have even greater capacity due to its 29.5-cubic feet of space. And when you fold back the rear seats, and there is nothing you can't haul in the RDX.

  • Fuel Economy.

With gas prices getting higher and higher these days, purchasing a vehicle with a good fuel economy is practically a must. While both SUVs certainly offer a decent gas mileage, with the Lexus RX 350 providing 20/27 miles per gallon, the Acura RDX outshines the Lexus model by getting an estimated 22/28 miles per gallon.
