Interior and Exterior Features

Acura’s luxury SUVs are made for drivers that want plenty of modern features in their vehicle. When it comes to interior specs, the 2015 MDX and 2015 RDX both include excellent features like power windows, power door locks, and a power moonroof. They both come equipped with heated front seats, a leather-wrapped steering wheel, and satellite radio. The MDX has a few small advantages over the RDX in this category: the 2015 MDX has three front power outlets, while the RDX only has two. Also, the front passenger seat on the MDX adjusts eight ways, while the passenger seat on the RDX only adjusts four ways.

The exteriors of both the 2015 RDX and 2015 MDX feature lots of wonderful options. Both SUVs include automatic headlights, body-colored heated exterior mirrors, and speed-sensing interval wipers. These two SUVs are evenly-matched when it comes to exterior features: one small edge that the MDX has over the RDX is that the MDX’s liftgate can be operated by its multi-function remote. The RDX does not have this feature.
