Hennessey Venom F5 Goodwood Hill! I timed with a frame counter at 50.55 seconds. At a later juncture I'll triple check it, but for now that's the number. It'll very obviously be +/- without a Racelogic Vbox system. But it'll be close.
That's good. Why on Earth they didn't time the hypercars is beyond me. The driver reported it was very good too and dynamically proficient and accomplished. He should know.
It didn't seem completely flat out either WITH a passenger.
