Erik-Jan, Actually, it had a safety line attached in case it did slip and fall off the ramp. Similar to that used by mountain climbers - it's slack, but there as a precaution. If it's the same as the commercial for the 1987-vintage Audi 100-5000 quattro, then you'll see the tether in the film below the centreline of the car. It was not winched up, though, it drove up: Now the spiked tires.....that's grip, baby! Too bad spikes are illegal here in Canada. BTW, the ad with the Audi climbing the Andes in Chile with no rubber on the rims: - no spikes there! There are many other films on the Nordic Audi web site (under "Filmer") - there's probably the test that the German TV show did on the different SUV's climbing the ski slope. Of course, they're essentially commercials, caricaturing the selling points of the vehicle (hence, the use of spiked tires). In my work I've driven my quattro-equipped sedan off-road (in fields and various construction sites), but I'd never drive off-road like the guy in our office that owns a Jeep. Of course, some say the difference between 2 wheel drive and 4 wheel drive is the distance you drive in before you're stuck.....and it holds true for our Jeep guy, who needed an excavator to drag him out this past summer. ;-) Cheers!
