在 1 2档，可以使车子很轻易且较长时间的打滑，这样就可以在弯道当中感受tts没有抓地力的表现，如弯道大油门，可以很明显的感受到，haldex的动力分配时很迅速的偏向外侧和后侧的，这样很有趣，你可以做出over steer，得益于新版的tts上面的haldex，以及tts的车重分配，我不确定，最高版本的haldex放在tt3.2上面是不是也会有类似的效果，因为：
1 tt3.2比tts推头更厉害
2 tt3.2扭力没有tts大
3 tt3.2的前部更重
...
我来回答一下小沙的这个问题
TTS上的HALDEX扭力分配器,据说得到升级......但我没在官方得到具体的升级信息.....TT3.2上的HALDEX扭力分配器,已具备小沙所说的特性,我试过低速调头大家油门,和转90度弯,给油.....确实明显感觉到扭力爆发于外侧和后侧,也有过渡现象,但能拉回来.....高速没玩过,胆子小....
至于3.2的头部比TTS重的问题,曾经开过小沙的车,头部确实更轻巧些,但TTS和TT3.2整车只差15KG,占总重的1%的比例.....感觉不知道是不是会有些主观放大.....需要查到这两颗机头的确切重量才能做对比.....
下面是一段官方对HALDEX的解释,自己看吧.....
quattro for cars with transverse engines
To ensure the optimum distribution of engine power for each model, Audi uses specially configured all-wheel drive systems that vary in design.
The Haldex® clutch is an electronically-controlled multi-plate clutch. It performs the function of the Torsen centre differential in cars with transverse engines, such as the Audi A3, A3 Sportback and Audi TT.
It ensures that engine power is permanently distributed between the front and rear axles as and when required.
The Haldex clutch works by reacting to differences in the rotating speed between the front and rear axles. This causes variations in the system’s hydraulic pressure, which in turn compress the clutch plates together to balance the distribution of power between the front and rear axles. So if the front wheels begin to lose traction, the Haldex clutch channels power to the rear. And the greater the difference in rotational speed, the higher the pressure applied to the plates – which means that more engine power can be transmitted to the rear axle.
