BMW Motorsport announces an upgrade to their Z4 GT. The goal of these latest modifications is to improve aerodynamics efficiency and increase car’s competitiveness in the GT3 classes. The drivetrain has also been extremely revised to provide additional benefits on the race track.

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 BMW Z4 GT3 launched in 2010 and a year later, Team Schubert won the Dubai 24 hours. This was the first outright victory for the BMW Z4 GT3 at a marathon race of this scale. Expectations are high for 2011 as well and more GT3 teams are expected to take advantage of these upgrades.

Press Release: The modified BMW Z4 GT3 has survived its baptism of fire: the GT customer sports car proved itself in a series of intensive tests in recent weeks. The goal of the latest modifications was primarily to improve aerodynamic efficiency in order to ensure the car’s competitiveness in the many, hard-fought GT3 classes.

The BMW Z4 GT3, which was launched in March 2010, achieved its greatest success to date in January 2011. Claudia Hürtgen (DE), BMW works driver Augusto Farfus (BR), Tommy Milner (US) and Edward Sandström (SE) won the Dubai 24 Hours for Team Schubert. This was the first outright victory for the BMW Z4 GT3 at a marathon race of this scale, having already proven its potential with wins in its debut season in the FIA GT3 European Championship.

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 engineers have also fine-tuned the aerodynamics of the BMW Z4 GT3 for the new season, improving the car’s performance in this area. 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 car is available now at a price of 315,000 Euros (plus VAT) from BMW Motorsport Distribution, email address Z4GT3@bmw-motorsport.com.
