The sum of all senses.The BMW Z4 is a car to stimulate all the senses. The active shapes and avantgarde styling, superb handling, and exhilarating performance undpobtly make it a modern interpretation of roadster. Yet it never strays from the purist character of a true sports car. In a nutshell, the BMW Z4 gives new meaning to the term "driving pleasure", combining the classic qualities of a thoroughbred roadster with supreme handling and an absolutely authentic driving experience. An experience.
Technology
Dynamic Stability Control (DSC) not only optmises driving stability when starting or accelerating, it also improves traction. In addition, the system recognises unstable driving conditions such as under - or oversteering and helps to maintain a safe course for the vehicle. Advanced sensory technology monitors the wheel rotation speed, lateralacceleration and the yaw rate (rotation around the vertical axis). This data is processed to obtain information about the automobile as it is currently moving, as supplied by the accelerator and the angle of the steering wheel.
If these two lists of data do not match and the automobile's stability is threatened, DSC is activated and influences the brake system or the engine management. This action helps prevent dangerous situations such as skidding.
As a further development of ABS, CBC (Cornering Brake Control) is a standard feature with BMW, CBC enables the driver to use the brake power of the rear wheels in full, without any additional risks affecting the car's directional stability. Should the driver apply the brakes, for example, in a series of fast bends, the car may spin and oversteer even under slight brake pressure. This is a result of increasing pressure on the front axle, following a simple law of physics irrespective of the drive system and configuration.
Applying specific computer simulation programs, CBC is able to determine lateral acceleration from the signals emitted by the four ABS sensors. CBC thus recognises a bend and controls the build-up of brake power accordingly, with brake forces building up more quickly on the outer front wheel in a bend than on the other wheels and counteracting the spin.
Interior Mirrors with Anti-Dazzle Feature.
BMW was the first car maker to introduce anti-dazzle mirrors operating automatically inside. These so-called EC (Electrochromatic) mirrors are made up of a clear and a reflecting layer of glass with an ultra-thin film of fluid in between. As soon as this fluid is subjected to a certain tension, it changes its permeablity to light and the mirror grows darker.
This process is controlled by two light-sensitive sensors within the interior mirror comparing ambient brightness with the brightness in the mirror and thus determining any dazzle effect resulting, say, from the headlights of vehicles behind. Depending on requirements, the system will then cut back the degree of reflection infinetely by 10-60 percent. The EC mirrors are further supplemented by an automatic tilt function moving down the offside mirror automatically whenever the driver shifts to reverse and giving him a clear view of the curb.
