BMW Z1 | Kapısı olmayan otomobil | Sadece 19 bin km'de
Designers when creating this model used the most unusual engineering solutions. The body consisted of a hot-dip galvanized monocoque of stamped and welded sheet steel with a sandwich-type bottom. All exterior plating consisted of screwed plastic elements. The peculiarity of the design are unusual doors that retract into the threshold of the car at the touch of a button (including when moving).
The 170-horsepower 2.5-liter inline six-cylinder engine from the BMW 325i was installed on the roadster. It was located behind the front axle. Acceleration from zero to 100 km / h took 7.9 seconds, and the maximum speed was an impressive 225 km / h. Torque through a five-speed gearbox transmitted to the rear wheels.
The chassis with sporty tuning consisted of a front suspension on suspension struts from the BMW 3 Series and a completely new, so-called Z-shaped rear suspension. In the basic configuration, all 4 wheels were equipped with disc brakes.
In the process of creating the machine, the company received patents for several new technologies. According to the developer Harm Lagay (Harm Lagaay), in particular, the technology of creating xenon lamps, an integrated frame, a door mechanism and a pallet were worked out at the “Z1”.
The car was produced only 3 years. The model can be attributed to the exclusive, because it was released in extremely small editions (8,000 copies).
Many tuning studios involved in BMW have introduced Z1 tuning services into their model range - from the “tuning” of a serial engine to the implantation of a new one. For example, in 1995, Kelleners-sport offered its customers to install on the Z1 the S50 series motor from the model M3 3.0 E36. The upgrade also affected the steering, cooling and suspension systems. If the client wanted more than 286 hp, there were two options for further refinement. The first. Installing a special exhaust system and reprogramming the motor control unit. This gave an increase of 7 hp Second. It includes the first stage, in addition: replacing camshafts with new ones that provide greater valve travel, again reprogramming the engine management system, installing forged pistons, increasing the compression ratio, processing the cylinder head. The result - 330 hp
