2011 BMW Z4 GT3 test programme comes to an end

Article by Christian Andrei, on April 11, 2011

In recent weeks, the modified BMW Z4 GT3 has managed to more than prove itself after undergoing a succession of intensive tests. This means that this GT customer sports car has managed to survive what may be its baptism of fire. In conducting the current improvements, the goal was mainly to enhance the vehicle’s aerodynamic efficiency to make sure that it remained competitive especially in the hard-fought GT3 classes.

First launched in March 2010, the BMW Z4 GT3 accomplished its greatest success by January 2011. This sports car managed to win the Dubai 24 Hours under Team Schubert, which includes German driver Claudia Hürtgen, BMW works driver Brazilian Augusto Farfus, American Tommy Milner, and Swedish driver Edward Sandström. For the BMW Z4 GT3, this was its first ever outright win for a marathon race at this scale.

It had previously shown it had potential by winning in its debut season during the FIA GT3 European Championship. This series version of the BMW Z4 has a unique appearance due to the narrow wheel arches, long wheel base, elongated bonnet, and the driver compartment that goes to the car’s rear. It is this two-seater that gave BMW Motorsport engineers the foundation for creating a competition racing GT3 car.

One of the main differences between the racing version and the production one can be seen under the hood. Powering the GT3 car is the 8-cylinder 4.4-liter engine while the BMW Z4 is equipped with the 6-cylinder engine.

For the new season, BMW Motorsport engineers made sure that the GT3’s aerodynamics is fine-tuned in order to enhance the performance in this region. Electronics-wise, there are still a number of innovative BMW solutions that many private teams can expect. Engine management is now controlled by the modern ECU408 with all the actuators being controlled by the electronic Power400 control unit. Power from the engine is channeled with the se of a sequential 6-speed gearbox. The gearshifts meanwhile can now be activated with the use of two paddles.

Munich, 8th April 2011. 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.

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.
