This 1990 BMW Z1 is finished in Ur-Green Metallic over beige and green upholstery and is powered by a 2. 5-liter inline-six paired with a five-speed manual transmission. Equipment includes a black soft top, retractable doors, 16″ Style 11 alloy wheels, an Alpine audio system, and power windows. The Z1 was the first concept vehicle developed under BMW Technik GmbH and features removable body panels constructed of GE’s Xenoy injection-cast thermoplastic along with a roll-hoop integrated into the windscreen surround, continuously zinc-welded seams, and vertically retracting doors. Exterior equipment includes a manually retractable black soft top, A-pillar-mounted power-adjustable side mirrors, a rear diffuser, and dual exhaust outlets. The 16″ Style 11 alloy wheels are mounted with Sportrack tires measuring 225/50. The Z1 introduced a multi-link rear “Z axle” design, and the car was factory equipped with a MacPherson strut front suspension and Bilstein coilover dampers. Stopping power is provided by anti-lock discs at each corner. The interior features bolstered bucket seats upholstered in beige and green as well as a black dashboard. Cabin amenities include an Alpine audio system, a digital clock, and power windows.
