As the bigger SUV, the MDX takes first place for interior passenger and cargo room. However, the Acura MDX vs. Acura RDX exterior comparison balances things out, as the RDX is a more agile SUV that can effortlessly slide into tight parking spots and make packed city streets an easier experience. So, when comparing the Acura MDX and RDX, the most important factor to keep in mind is that the MDX is a spacious and powerful three-row SUV, while the RDX is an agile and efficient two-row SUV.
The MDX can seat seven; the RDX has five seats. The Acura MDX trim levels offer you up to 41.8 inches of first-row legroom, 38.5 inches of second-row legroom, and 29.1 inches of third-row legroom; the Acura RDX has 42 inches of front legroom and 38 inches of second-row legroom. Acura MDX vs. Acura RDX headroom is essentially a tie in the second row, but the RDX has 40 inches in the front seats, while the MDX has 38.5 inches.
The Acura MDX can store up to 18.1 cubic feet of cargo behind its third-row seats, 48.4 cubic feet behind its second row, and 95 cubic feet behind the front seats. In the Acura RDX, you’ll be able to store up to 31.1 cubic feet behind the second-row seats and 79.8 cubic feet behind the front seats.
As for Acura MDX vs. Acura RDX dimensions on the outside, things begin with the wheelbase. The RDX SUV’s wheelbase measures 108.3 inches long, while the MDX has a 113.8-inch wheelbase. This does wonders for agility. So, too, does the RDX SUV’s 187.4-inch long exterior provide ample agility; the MDX has a 198.4-inch long exterior. The MDX is also 78.4 inches wide vs. the 74.8-inch wide RDX, which is the other most important factor towards its agility.
However, with its more stable size and spacious interior, the MDX is undeniably the better road trip machine for larger families. The RDX, though, is far better for drivers with smaller families and a focus on city commutes. Either can be yours for a great price with our new Acura specials.

The Acura MDX is a larger SUV than the Acura RDX and also offers another row of seats so that you can fit more passengers. The Acura MDX is 198.4 inches long and provides three-row seating for seven; the Acura RDX is 187.4 inches long and has five seats across two rows. The MDX, as you’d expect from this difference, has more maximum cargo room.
The 2024 Acura MDX has a 12.3-inch Dual-Content Center Display that can be controlled via an intuitive True Touchpad Interface. This control method will become second nature as you drive your new Acura MDX. Rather than making you lean over to touch the screen and potentially causing you to take your eyes off the road, this control method is within easy reach and provides seamless control.
Due to its high-performance turbocharged engine, the manufacturer recommends that you use premium 91-octane unleaded gasoline in your new Acura MDX. However, it is possible to use regular 87-octane unleaded gasoline in an Acura RDX without causing damage; any gasoline with an octane rating lower than 87 should not be used in the Acura RDX, as engine damage can occur when using this fuel.
