Like other models in the Acura lineup, the RDX and MDX SUVs bring you the latest technology features, plenty of high-end amenities inside the cabin, and dynamic drives on the road in San Jose. But what’s the difference between Acura MDX and RDX models — and which is the best fit for you? In the Acura MDX vs. RDX comparison below, Capitol Acura looks at the dimensions and features for both vehicles to help you make the right call!

Acura MDX vs. RDX: Interior Dimensions

For some San Jose drivers, the difference between the Acura MDX and RDX in terms of cargo and passenger space will determine which model is a better fit. Both interiors feature high-quality seating and trim materials, smartly designed storage features, and more. However, the RDX offers a bit more space for passengers and cargo. Compare the RDX vs. MDX dimensions below:

  • At 196.2 inches long and 77.7 inches wide, the larger MDX could be more difficult to maneuver in tight spaces. By contrast, the RDX measures 186.7 inches long and 74.8 inches wide.
  • First and second-row legroom is about on par in MDX and RDX, but the MDX’s larger size allows for a more spacious third row, as well as more shoulder room in both the first and second rows.
  • The RDX provides a maximum 79.8 cubic feet of cargo space with all seats folded flat, compared to 95.0 cubic feet inside the RDX.

Next, we’ll compare the RDX vs. MDX engines and performance specs. Both SUVs are fun to drive, but not at the expense of fuel economy.
