We're excited to dive into this year's Acura ADX vs. RDX debate for two reasons: First, these SUVs are both great examples of luxury craftsmanship at affordable prices, and second, the RDX, while currently a gas model, is anticipated to be redesigned as a two-motor hybrid in the next couple of years!1 To view the new ADX and RDX in all their glory, visit Muller Acura of Merrillville today.


What's the Difference Between Acura ADX and RDX Specs?

Aside from the fact that the RDX puts out much more horsepower, the other major difference between these SUVs is their drivetrains: The ADX is a front-wheel-drive vehicle with an available all-wheel setup, while all five RDX trims are fitted with Super Handling All-Wheel Drive. Test out the Acura ADX AWD vs. RDX SH-AWD, and you'll notice that the ADX uses a traditional setup that increases overall traction, while the RDX has a more performance-focused feel, thanks to the torque vectoring system that enhances stability and cornering.

  • The RDX focuses on sporty power, while the ADX makes a practical daily driver.
  • FWD is standard in the ADX; AWD is standard in the RDX.

How Roomy Is the Acura ADX vs. RDX?

Park the ADX and RDX side by side, and you might not notice a significant size difference. Even their front and rear legroom is nearly identical. That said, the ADX trunk is compact yet functional at 23.2 or 24.4 cubic feet (depending on trim), while RDX cargo space is 29.5 cubic feet. The RDX also boasts 104 cubic feet of passenger volume, whereas the smaller ADX contains around 97 cubic feet of passenger space in its standard configuration.

  • Both compact SUVs seat five and share some similar dimensions.
  • The RDX has a bigger trunk, longer wheelbase, and more passenger volume.

What's Happening With Acura ADX vs. RDX Fuel Economy?

Whether you're road tripping or commuting, the ADX will stretch your fuel budget the farthest. Not only is its 1.5-liter engine more efficient, but its lighter weight and smaller size help keep your MPG high. That's not to say the 2026 RDX trims guzzle gas: You can still expect an EPA-estimated 26 or 27 miles per gallon on highways,2 which is better than its competitors: See our Acura RDX vs. Honda Passport comparison for details.

Summary
  • The ADX scores better fuel economy due to its smaller build.
  • RDX models are still competitive in terms of MPG compared to other makes.
