Eighteen years ago, a video surfaced online that made car enthusiasts pause and stare. A sleek Lincoln Mark VIII, its doors gliding downward and vanishing beneath the vehicle, promised a future where getting in and out of a car felt like stepping into the future, literally. This was Jatech’s Disappearing Car Door, a concept that sparked curiosity and wonder but never made it past the prototype stage.
Jatech, a California-based design and technology firm, unveiled their rotary drop door system in the early 1990s, aiming to rethink how we access our vehicles. Unlike traditional hinged doors that swing outward, requiring ample space and sometimes awkward maneuvering in tight parking lots, Jatech’s doors slid downward into a compartment beneath the car. “The designers of the exciting Disappearing Car Door technology are now in a position to equip your favorite car with our cool, sexy, safe, and convenient automatic car door,” Jatech’s website boasted in a 2010 snapshot.

How did it work? The door, mounted on a robust track system, was guided by a motor that initiated a controlled descent. Once activated—likely by a button or remote—the door would lower itself, sliding into a sealed undercarriage compartment. This design eliminated the need for door handles and the space required for swinging doors, making it a dream for urban drivers squeezed into cramped parking spots. Jatech claimed the system enhanced a car’s structural integrity, reduced weight, and even improved safety by allowing easier egress in emergencies. “What Jatech also claims is that its doors improve safety and make it easy for occupants to get out in the event of a crash,” noted a 2013 DriveSpark article.
Prototypes of this system appeared on vehicles like the Ford Explorer, Chevrolet Corvette, and, most famously, the Lincoln Mark VIII. The story goes that Lincoln, concerned about the Mark VIII’s hefty doors in tight urban environments, commissioned Joalto Design to explore solutions, leading to Jatech’s involvement. Ford even invited Jatech to its design subsidiary Ghia in Italy, where early concepts took shape. The result was a mesmerizing demo: a door that didn’t just open but disappeared, leaving onlookers stunned. “Rotary drop doors can be installed in place of a car’s standard hinged front doors or—with the removal of the central B-pillar—can be extended to allow entry to both the front and rear compartments,” CNET reported in 2011.
Complexity was the first hurdle, as the door’s internal mechanisms demanded a complete redesign of the car’s understructure, leaving no room for typical features like storage pockets or intricate panel designs. The main issues all had to do with reliability since a motorized system sliding into the undercarriage was exposed to road grime and debris. Would dirt clog the tracks? Could a minor fender-bender trap occupants inside? Jatech insisted their doors were safer than traditional ones, but critics weren’t convinced.
Cost was another sticking point. Retrofitting a car with disappearing doors required extensive modifications, driving up production expenses. Major automakers like Ford and General Motors, despite early interest, never committed to mass production. By 2010, Jatech was still pitching their invention, but the company eventually dissolved, leaving behind a handful of prototypes and a viral video that refuses to die.
