One of the core concepts behind the Z1 was an odd one: that anyone ought to be able to exchange all the exterior bodywork on the car in an afternoon, with just basic hand tools. In that way, any owner could rid the car of all evidence of minor accident damage, or completely change the exterior color by swapping their red panels out for blue ones.
Yet perhaps even stranger was the car’s doors, which opened by sliding down into the Z1’s oversized sills. Lamborghini, eat your heart out. Other notable bits included a standard 2.5L M20 inline-6 with around 170 horsepower, a five-speed Getrag manual as the sole transmission available, and one of BMW’s first-ever multi-link rear suspension designs, which went on to be used in the E36 3-Series.
