A difference between the production and racing car can be found under the bonnet: while the production version of the BMW Z4 is driven by a six-cylinder engine, the GT3 car is powered by a 4.4-litre eight-cylinder engine.
For the electronics, the private teams can look forward to innovative BMW solutions: The modern ECU408 takes over the engine management, while the Power400 electronic control unit is responsible for controlling all the actuators. The power is transmitted through a six-speed, sequential gearbox. Gearshifts are now initiated using two paddles.
The steel body of the modified Z4 GT3 comes from BMW Plant Regensburg. A safety cell made of extremely rigid, precision steel tubing is then welded into the body. The engine block of the V8 engine is produced in the BMW foundry in Landshut. Front and rear wings, bonnet, roof, fenders and many other components are made of carbon fiber reinforced plastics (CFRP).
