BMW Motorsport has officially launched the new BMW Z4 GT3 in early March and had completed the first test at the same unit. With a long hood, wheel arches are lit, the long wheelbase and narrow projection, Roadster BMW engineers were given a good basis for development which is close to GT3 racing car production. Based on a series concept, the front axle of the BMW Z4 GT3 is equipped with a tubular stabilizer bar with adjustable blades that comes as a completely new design. As with the series version of the BMW Z4, the rear axle is designed as a longitudinal link axle. Front and rear wings, bonnet, roof, fender and many other components are made of carbon fiber reinforced plastics (CFRP), making the GT3 1,200 kilograms lighter.
The fitting of the V8 engine had a considerable influence on the development of the BMW Z4 GT3. The largest difference between production and racing car, however, lies under the bonnet. The production version of the BMW Z4 is driven by a six-cylinder engine, while the GT3 is powered by a 4.0-liter eight-cylinder engine, which produces over 480 bhp.
Electronically, the GT3 engine management of is controlled by the modern ECU408, while the Power400 electronic control unit is responsible for controlling all the actuators. The power is transmitted through a six-speed, sequential gearbox with “Quick Shift” function. As with all cars in the BMW customer racing range, cost-efficiency was also the emphasis in the GT3 development. The BMW Z4 GT3 is available as a racing car and priced at 298,000 Euros (including VAT).
