Genesis outlines engineering behind pillarless coach doors for upcoming GV90 Neolun
The luxury automaker uses high-strength steel beams, hidden roof supports, and specialized airbags to eliminate central B-pillars while maintaining structural safety.
The short version
- Genesis revealed structural details for the 155-pound rear-swinging coach doors featured on the Neolun version of its planned 2028 GV90 SUV.
- The design removes the traditional body B-pillar, replacing it with 1.8-gigapascal steel beams inside the doors and a concealed steel roll cage in the roofline.
- Occupant safety measures include front-seat-anchored seatbelts, heavy-duty door stoppers, and a roof-mounted airbag system.
- Official crash-test ratings and final production timelines for the pillarless setup have not yet been evaluated by independent safety regulators.
