Acura is a prominent brand with luxury designs with a sporty performance. Two of the most famous vehicles in their lineup include the RDX and MDX. While they are similar in many ways, there are some serious differences between the Acura RDX Vs. MDX. It’s vital to know these to ensure the right decision for your next vehicle. 

There are many Acuras to choose and two of the sportiest, sleekest selections include the RDX and MDX. There are some distinct differences and a clear winner between the two in our option. Read on to learn more about the differences in the exterior, interior, performance, features, and beyond. 

Acura RDX vs. MDX: Exterior

The first consideration is the exterior of the RDX and the MDX. The larger the exterior of the vehicle, the more room there is inside the machine. The MDX is the winner in terms of physical size.

Here are the dimensions in the RDX and MDX, respectively:

  • Total Length: 187.4198.4 inches
  • Wheelbase: 108.3113.8 inches
  • Width (with mirrors): 74.878.4 inches
  • Height: 65.767.1 inches
  • Ground clearance: 8.26.7-9.4 inches

The MDX is the winner in almost every category here. 

The larger size of the Acura MDX means more room inside for passengers and cargo. The base ground clearance is also higher than the base Acura RDX ground clearance, which means it’s far easier to go over bumps on the road without worrying about damaging the bottom of the machine. 

Size Winner: Acura MDX

Acura RDX vs. MDX: Interior

The interior is the next step when looking at the Acura RDX Vs. MDX. We will focus here on the materials for the interior and the dimensions each rider will find for the headspace and beyond.

Both vehicles come to life with premium materials. They offer unique details that bring a sporty and respectable appearance for the driver. 

Here are the measurements for the inside of the RDX and MDX respectively:

  • Front row headroom: 4038.5 inches
  • Front row legroom: 4241.6 inches
  • Back row headroom: 3838.1 inches
  • Back row legroom: 3838.5 inches

There is a winner in each portion of the vehicle.

The Acura RDX, despite being smaller on the outside, offers more room than the MDX for passengers and drivers in the front of the vehicle. However, the Acura MDX pulls ahead again with more room in the rear of the car for the passengers’ heads and legs. If you’re tall and don’t use the back row, the RDX is best. However, we’d still give the crown to the MDX here.

Interior Winner: Acura MDX

Acura RDX vs. MDX: Performance

Next up is the performance of the Acura RDX and MDX. Performance is critical for most people, especially if you care about a fun ride or have to commute often in your Acura selection.

Here are the performance features you’ll see in the Acura RDX:
