The "wing" is a spoiler to prevent lift rather than a wing add downforce. I think the engineers needed to kill the lift at high speeds, probably only 100+ but it would be difficult to explain to customers in most countries why they had something on your car that would only operate when they were breaking the speed limit?
That said the original Audi TT had lift problems below 100mph and they added a wing.
