All manufactures winter test these days, even the likes of Pagani. Never mind the fact that only the most insane lunatics will ever take their Huayra BC out in the snow. For all intensive purposes, the track focused Hyper Car will never see even a single snow flake, Pagani still has to test it. Personally I think it is a clever ploy for the engineers to go on a skiing vacation. In any rate, good thing they do test, otherwise we wouldn’t get great video like this one.
