haldex是基于前驱的适时四驱,平时的驾驶感觉基本和前驱的买菜车一样,只是电脑决 定在需要的时候把动力分配到后轮。 subaru, audi 除了a3以外的quattro,bmw 的xdrive是真正的实时四驱,动力分配前后 接近50:50,驾驶感觉远胜haldex 俺长期驾驶过volvo v60, audi a4和bmw 3, 这是俺的个人感受 所以volvo新一代还是继续用廉价的前驱haldex,俺老很失望

http://www.awdwiki.com/en/haldex/ Haldex I,II Under normal driving conditions (driving at the constant speed, no silppage) , the torque distribution is 90/10 front to rear. When the clutch is locked, torque is evently distributed between the axles (50/50). Haldex Generation III, IV, and V based all wheel drive systems are proactive . The electronics can pre-tension the clutch and activate all wheel drive before a wheel slip occurs.

第五代已经不是轮子转速差驱动的了 可以随时启用AWD http://www.borgwarner.com/en/Haldex-AWD/products/Pages/Haldex-G As the function of the Haldex GenV is independent of the differential speed between the front and rear axle, full locking torque, if needed, is available at any given time and speed.
别人的试驾比较 http://www.awdwiki.com/en/testdrive/ Lenta.ru did a comparison test of Audi TTS quattro DSG (Haldex automatic all wheel drive) and Audi A5 quattro automatic (quattro evolutions asymmetric Torsen-based full-time all wheel drive). ...... But most drivers are likely to find the behavior of Haldex TTS more familiar and safer than the habits of the car with "Torsen". This was confirmed by my colleagues, who drove both cars on snow-covered ground. According to them , TTS, in contrast to the A5, does not scare the driver off with a sudden drift in response to a throttle increase, and in order to cause a skid of the rear axle, it was much easier to "pull the handbrake," than to make themselves hit the gas pedal. But I personally find myself closer to the mechanical "Torsen" - it has a character! It is interactive and involves the driver deeper in the process of driving. Yes, it requires attention to the slightest nuances in the behavior of the car and more accurate work with the gas pedal. But it is the character that we love in cars.

你引的90/10是错误的, Haldex就是95/5的太公四驱.
