Warning: after watching this video you may suddenly feel the urge to move to a cold location with a frozen lake near by. Ok summer has its advantages, and we might be exaggerating a little bit, but you’ll get our drift after once you hit the play button. 
This particular lake is called Tisleifjorden, and is situated on the northern part of Norway. It is here were students learn how to drive on ice and snow covered surfaces in cars that range from a Fiat Panda to an Impreza GT or Audi R8.
We also get to see the use of quattro in environments like this, particularly when an A8 helps in pulling an A3 out of the snow.
