Why it matters

The Z1 was the first product of the newly founded BMW Technik GmbH and was meant to refresh the company image with a modern two-seat roadster. Its electrically driven doors that drop into the sills, its zinc-coated steel structure and its removable plastic body skin set it apart from every other BMW of its time. Only 8,000 were built, unusually few for a BMW of the period.

History

Management decided in early 1985 to build a two-seat sports roadster, and the work went to BMW Technik GmbH. Harm Lagaay, hired from Ford of Europe, became design chief under Ulrich Bez, who headed the new division. A working prototype existed within a year, using engine, drivetrain, front suspension and interior parts from the 3 Series. The production car was shown at the 1987 Frankfurt show, and BMW planned to build 5,000 on a dedicated line in Munich.

Production began slowly in 1988 with 58 cars, and customer deliveries started in March 1989. BMW claimed 5,000 confirmed orders at the launch, but demand fell short because many buyers were investors rather than drivers. Production was curtailed in favour of more profitable models and ended in summer 1991, after 8,000 cars plus 12 pre-production units.

06Reference

Identification guide

How to tell an original from a replica or later conversion.

A Z1 has doors that retract downwards into the sills and a galvanised steel inner structure covered by demountable, injection-moulded thermoplastic body panels. It rides on alloy wheels made only for the Z1 and has a 2,450 mm wheelbase. The sources disagree on the paint range: the auction description says four colours, while the build statistics page lists six (Dream-black, Ancient-green, Fun-yellow, Magic-violet, Top-red, Pur-blue).
