To get visco out of the last situation you need to pull the parking brake. It will stop thr free wheel giving traction to the one on the hard surface. But other than the last test visco seems to react faster than haldex. Ive got a 2001 XC70 with visco. Im quite impressed what it can do on sandy hills and in the snow

Єрунда.. вся причина не в віско, а в різних системах track/dstc. Модифікація з віско має більш жорсткий режим роботи імітації блокування.. тому машина легше зїзджає при контакті переднього колеса. Але на задню вісь, машина з віско, імітації немає ВЗАГАЛІ. В машини з dstcімітація більо мяка. Тому зїхати одним переднім колесом їй важче. Але в неї є імітація блокування і на задню ось.. тому вона вмії зїзджати за рахунок заднього колеса. Віско має, ЗАВЖДИ, паразитний момент на задню вісь .. тому їй легше на ожеледиці і піску, так як халдекс постійно вмикається-вимикається. Проте на важких грунтах віско передає момент з більшим запізненням, від чого машина може закопатись. Халдекс працює швидше. Халдекс вмикається швидко з ударами, від чого страждає трансмісія. Віско працює мяко - трансмісія страждає менше. Тому, раджу Вам, більш детально розібратись в повному приводі.

What we see here, is that the average driver, is not going to notice any difference in practice. We have an xc70 2005. Has it been great on long drives - absolutely. Has the AWD helped - absolutely. Is it an off road vehicle - no. If you find yourself in a situation where only 1 wheel has traction, then you have already messed up, and should not be there. Is the AWD going to save you - probably not.

Keeping track of the Maxiecu output values has been a great addition to the test, thank you! This goes to show how an essentially identical vehicle with different AWD systems treats different wheel slip situations completely differently (along with the limitations of a viscous coupling to sending torque to the rear axle in this case). I know this is a bit off-topic for this channel, but I really wish you were a sort of independent car review channel like Marek to also hear your personal opinions of the vehicles you test.

Let's say unpredictible, and not as efficent as other systems, you can't determine how much torque goes to the rear axle, it is afected by too many external.factors as: if it's the last test done overheating, the maintenance done to the diff...
