With its elongated bonnet, the driver’s compartment towards the rear of the car, long wheel base and narrow wheel arches, the series version of the BMW Z4 boasts an unmistakable appearance. The two-seater provided BMW Motorsport engineers with a good basis for developing a competitive GT3 racing car. 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.

BMW Motorsport has further developed the BMW Z4 GT3 specifically for the 2012 season. The engine now turns up to 9,000 rpm and has a new exhaust system. The rear wing is now made from carbon fibre instead of aluminium and produces greater downforce – with less drag. The brake cooling on the front axle has also been optimised. In addition, there is a new rear axle differential. The tank, which has a capacity of 115 litres, extends the team’s strategic manoeuvring room in long distance races. In the 2012 version of the BMW Z4 GT3 the pedal systems are adjustable and can be set individually for each driver. When it comes to 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 car 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. BMW Plant Dingolfing contributes the rear axle differential, among other things. Front and rear wings, bonnet, roof, fenders and many other components are made of carbon fibre reinforced plastics (CFRP). The BMW Z4 GT3 in its racing version is available at a price of 340,000 Euro (plus VAT). If interested, please send an email to Z4GT3@bmw-motorsport.com or send a fax to +49 89 382 208 55.
