The BMW Z Series traditionally is a roadster manufactured by the German automaker BMW beginning with the Z1. Successor to the BMW 507 after nearly 30 years, it has been produced in four different generations, coupe variants, one super car, and one concept. The Z1 was a limited production European run for BMW, whereas its successor the Z3 was the first mass produced roadster for BMW. The original Z in Z1 stood for Zukunft (German for future).

Z Series vehicles can be largely differentiated by the underlying platform:

The BMW Z1 is a two-seat roadster developed by BMW and produced from March 1989 to June 1991. The Z1 featured unusual doors which, instead of opening outward or upward, dropped down into the door sills. Only 8,000 examples of the Z1 were produced.

The Z3 was the first modern mass-market roadster produced by BMW. The Z3 was introduced as a 1996 model year vehicle, shortly after being featured in the James Bond movie, GoldenEye. The entire 1996 BMW Z3 roadster production run, more than 15,000 roadsters, was sold out by the time the car was introduced. There were a few variants of the car before its production run ended in 2002, including a revised tail styling for 1999 and coupé version for 1999, and M versions for both. It was manufactured and assembled in Spartanburg, South Carolina.
