An All New ATC passenger side conversion on a pre-owned 2023 GMC Yukon XL 4WD Denali transforms a premium full-size luxury SUV into a fully wheelchair-accessible vehicle. This specific modification serves as a rugged, premium alternative to traditional wheelchair-accessible minivans, offering off-road capability and high-end luxury without sacrificing the vehicle’s standard passenger capacity or signature styling.
The Conversion Mechanism
Unlike ramp-based minivan conversions, ATC utilizes a patented hydraulic gull-wing door and hoist system.
- Operation: A remote control opens the entire side door upward. A heavy-duty platform then extends outward and lowers completely to the ground.
- Flexibility: The wheelchair user rolls onto the platform, is lifted into the cabin, and can either drive the vehicle or ride as a front-row passenger (determined at the time of build).
- Seating Retention: Because the lift mechanism operates through the front passenger or driver side door, the Yukon XL retains its second and third-row seating, accommodating up to 5 additional passengers.
4WD & Denali Constraints
Opting for a 4WD Denali trim introduces specific engineering parameters that you must factor into the build:
- Interior Vertical Clearance: The 4WD system raises the vehicle’s drivetrain and floor profile. This reduces interior head clearance compared to 2WD configurations. ATC notes that standard 4WD builds generally accommodate wheelchair users up to 57 inches tall while seated.
- Wheelchair Width: The entry threshold typically limits wheelchair widths to 28 inches or less.
- Mechanical Requirements: The vehicle must be equipped with the factory Max Trailering Package and load-rated tires to offset the added weight of the hydraulic lift system.
