Seating Capacity

The RDX is a five-passenger crossover SUV that features two rows of seating. The second row is at a 60/40 split to allow for several different seating and cargo configurations. The center seat in the rear can also fold down when you only have four passengers inside and becomes an armrest with cup holders between the two rear passengers. The second row in the RDX also features a flat floor and ample space underneath the first row of seats for added legroom.

The MDX offers models that accommodate up to seven passengers with a second-row bench seat, or six passengers with captain’s chairs in the second row.
