Light it should be and basically suitable for racing. Therefore, all unscrewable parts are from aluminum. It has a hard suspension, hard as a rock. It runs with high revs. Is just an aspirated engine. And listened attentively, it is available only with double clutch and seven gears. But this combination is remarkable.

The slightly higher weight is tacitly accepted, because the acceleration is not in principle, but better in this case with this type of transmission. It is said that one has already tried it once about 30 years ago, but the computing capacity was not large enough.

It is precisely about the interaction of the two clutches. The one opens and the other closes at the same time. Here the milliseconds are hidden, you inevitably give away with themanual gear change. However, for the super fast interaction much computing power is necessary.

Are both open just a little too long at the same time, acceleration time is wasted. However, common closing time is not at all good for the transmission and the clutches and can also cost time. Probably Porsche includes all possible parameters, such as the slip at the wheels.

In addition, you can still choose the gear changing at lightning speed. Whether the then final increases the wear? If not, it could indeed remain switched on. In addition, one can now pull at both paddles simultaneously, in order to take abruptly the torque, e.g. to increase the lateral guidance rear, from the drive wheels. Pressing both, it's just as quickly available again.

As usual with racing cars, the transmission stages are close together. The top speed is achieved naturally in top gear. Would it be a manual transmission, a lot of work would be to do to change the gears. Further in the drive train is still a transverse differential lock also active with a lot of computation work. Even the engine bearing is included in the dynamic concept (Figure 7).

But Porsche has with the magnificent engine the misfortune at the beginning that the screws of the special titanium connecting rods can loosen themselves. The result: they can penetrate the engine block and gushing engine oil sets the car on fire. In the still faultless GT3 new engines with special locking of the rod bolts are installed. 12/14
