VMI pioneered the Northstar in-floor ramp system in 1993 to satisfy wheelchair user needs for additional interior space and a safe, clean, obstruction-free vehicle interior. After two decades of refinement, the Northstar remains the most technologically advanced ramp system on the market. The Northstar ramp simply slides out from within the vehicle floor, rather than taking up valuable space inside the vehicle. The significant advantages of the Northstar in-floor ramp system over traditional fold-out ramps make it VMI’s best-selling conversion.
