Which is bigger the Acura RDX or MDX?
The Acura MDX is bigger overall than the RDX. It’s a three-row midsize SUV, while the RDX is a two-row compact luxury crossover, so the MDX offers more interior space and seating capacity.
Size and dimensions: how they compare
The following points highlight how exterior and interior dimensions stack up between the two models in their current generations (MDX 2022–present vs RDX 2019–present).
- Overall length: The MDX is longer than the RDX, contributing to more interior room and a larger footprint on the road.
- Wheelbase: The MDX rides on a longer wheelbase than the RDX, which typically translates to more legroom and a smoother ride for back-seat passengers.
- Seating configuration: The MDX is a 3-row SUV capable of seating up to 7 (depending on trim and configuration), while the RDX is a 2-row SUV that seats up to 5.
- Interior space: The MDX generally offers more total interior volume, especially with all three rows in use, though the RDX delivers strong cabin space for a two-row model.
In summary, the MDX leads in length, wheelbase, and total passenger/cargo potential thanks to its three-row design, while the RDX remains the more compact option.
Practical implications for buyers
Seating and family use
For families or groups needing a third row, the MDX is the obvious choice due to its 3-row layout and higher passenger capacity. The RDX, with two rows, is better suited for small families or those who don’t regularly require extra seating.
Daily driving and maneuverability
The RDX’s smaller footprint typically makes it easier to park and maneuver in tight urban spaces and may offer a lighter steering feel and slightly better everyday fuel efficiency. The MDX trades some of that ease of use for greater interior space and versatility.
Bottom line
Across their current generations, the Acura MDX is the bigger model, offering more length, a longer wheelbase, and three-row seating. The RDX remains the smaller, more compact option with a two-row layout that emphasizes nimble handling and efficient everyday use.
Summary
Bottom line: If you need a larger vehicle with extra seating and cargo capacity, the MDX is bigger. If you want a more compact, city-friendly SUV with strong value and sportier handling, the RDX is the better pick. Consider how many passengers you regularly carry, how much cargo you need, and where you drive most often when choosing between them.
