Does that mean lift/drag of no better than 4:1?
The Audi R8 in 2002 had an L/D at Le Mans of 4.42:1.
If we go back to the early nineties, with the huge diffusers and twin plane rear wings,the TS010 was at 5.8:1 at Le Mans.
Even a crude, slapped together Dome wind tunnel model from 2011 was at 4.10:1.
Every time I come around to thinking that the new rules will be alright something like this comes along and puts me off again.

Our 003C has a 4/1 ratio which with a real 2 seater windshield as HyperCars have is about as high as you’re going to get.
