TheBMW Z18 is aconcept car developed by BMW Technik GmbH, the formerthink tank ofBMW. Unveiled in 1995, the Z18 combined elements of theBMW Z3 with those of anoff-road vehicle, creating what BMW described as the first "off-road roadster."[1]
BMW Technik GmbH, founded byBMW in 1985, was an independentthink tank created to develop innovative vehicle concepts featuring radical interior and exterior design elements. Some of its projects included theBMW E1, an early example of ahybrid electric car. FormerAston Martin chief executive officerUlrich Bez was the first head of the think tank, under whose leadership the Z18 was developed.
The Technik division has since been reintegrated into BMW as part of itsresearch and development department. Although the Z18 was first developed in 1990, it was not unveiled until 1995.[2][3]
The car featured styling cues characteristic of 1990s BMWs, including the signature kidney grille, and was based on theBMW Z3. The concept behind the Z18 was to merge elements of anenduro motorcycle, anoff-road vehicle, and aroadster, the first of which saw a rise in popularity during the 1990s. While the Z18 retained the general body shape of the Z3, it had a significantly higher ride height to enhance its off-road capabilities. The Z18's plastic body, mounted on a steel frame, was structurally similar to that of a boat, contributing to its weight of 1,560 kg (3,439 lb). Due to its increased ride height, BMW claimed that the Z18 could navigate shallow water passages with ease.[4][5][6]
BMW did not design a roof for the Z18, as it was conceived as a roadster. To accommodate the possibility of water entering the cabin, BMW reduced the number of components on the dashboard and waterproofed all interior elements. Additionally, the car was equipped with rubberfloor mats. The Z18 also featured collapsible rear seats that could be raised to convert it into a four-seater (2+2) and included an option to transform it into apickup truck.[7][5]
The Z18 was powered by the 4.4 L (268.5 cu in)BMW M62 V8 engine, which later found its way into the first-generationX5.[8] The engine produced 355 PS (350 hp; 261 kW), sending power to all four wheels via a 5-speedmanual transmission and afour-wheel drive system—both of which were later inherited by the X5.[9]
