Ford P68 — the redesign.
Since the brand new P68 was proven to be extremely fast, its was useless at generating enough downforce to keep it on the road.
Ford came up with an idea: just give it a massive rear wing!
And so it went, in 1968 at Brands Hatch, with Denny Hulme at the wheel of rocket with a spoiler on top.

Also known as the Ford 3L GT (3 litre, due to the new strict regulations about engine size that FIA introduced to the Group 6 in the late 60s).
Monocoque chassis with reinforced steel, 3 litre V8, Goodyear tires and a Hewland 5-speed transmission. The best thing about the P68 was its drag coefficient: 0.27 Cx. Ford was very proud of this achievement, since it allowed the P68 to be propelled at speeds up to 350kmh, faster than F1 cars at the time.
Its hand crafted design was supposed to give it massive downforce at the rear, but it didn’t turn out this way. It was highly unstable in the corners, even at relatively low speeds.
