My car LOVES the cold weather. To the point where I find the summer performance disappointing. In the winter, I could swear it has 40 WHP more! It's bitter sweet because of the decreased traction. :-/
i dont know about 40 but it seems to me to be noticable in my lap times. either im getting better this winter or its making more power or both.
