The 2000 Buick Lacrosse

The LaCrosse's most notable feature is its ability to be quickly transformed-with a single voice command-from a luxury car to a light cargo carrier with an open bed. The tailgate electronically slides downward and under the vehicle, and the rear window and rear portion of the roof slide forward to reveal the cargo area. During this operation, the front section of roof moves slightly downward to accommodate the sliding panels. LaCrosse's four doors are power-operated and hinged at the front and rear pillars, opening at the centre pillar for easy access. The interior showcases consumer-friendly advanced technology such as voice-activated controls in place of the switches and displays usually mounted in the instrument panel. The only visible controller is a single trackball-like device installed in a console. The driver uses the controller in conjunction with voice commands to operate all systems except throttle, brakes and steering. Features selected by the driver are projected on the windshield in re-configurable color heads-up displays for both the driver and front passenger

The 1956 Buick Centurion

The 1956 Buick Centurion was an aerodynamic four-seat coupe with a patented rear-mounted television camera,  A receiver on the instrument panel displayed images from the camera, thereby rendering the rear-view mirror obsolete. The camera was mounted in a tailcone inspired by a jet fighter, a recurring theme in concept cars of the '50s. Front seats automatically slid back when the doors were opened for easier entry and also moved forward to provide entry and exit to the back seats. A cantilevered steering wheel positioned the steering shaft down the center of the car, allowing more legroom for the driver.

Centurion is now owned by Sloan Museum.
