At 180.3 inches, the 2018 RDX sits in a class sweet spot for compact luxury, long enough to accommodate a generous wheelbase while remaining agile in urban environments. The length supports a composed highway ride and reduces abrupt pitching over uneven pavement.

Seating And Headroom Configuration
Standard seating for five provides ample headroom and shoulder room for front and rear occupants. The raised seating position enhances visibility and ingress, while supportive seat bolsters help keep passengers secure during spirited drives.
