The GT40 was actually a pretty derivative design - with a chassis and overall structure partially borrowed from Lola.
But the GT40 as it came from Lola was not a winner right away. While the Mark I GT40 is a bit more pure, and a lot more beautiful by many eyes -- it was not a race-winner.
The GT40 started winning races with the Mark II GT40 with its huge air scoops, front sill spats, and other aero mutations to the overall design.
But still - it is hard to argue with the clean beauty of these initial concept prototypes.
