No way in the world that video was done without spiked tires. Right? Yes, parts were in slow motion but what was the speed without spikes on ice in the slalom?
It is not typical not to use spikes on ice. The driving would change to much during the day. Spikes on ice give you a pretty consistent driving experience, it is a must for beginners or they never learn to drift.
Yes, I prefer Quattro on ice while still driving a BMW AWD now. In Germany you don't have much snow anyway, in 10 years no one will understand the question here anymore I fear who handles best on snow. What was snow again 😳 And it's anyway mostly a question of the tires, the AWD concept is only a nuance, guess we can agree on that
