This is what Christian von Koenigsegg and James Glickenhaus said when asked about the record by Top Gear:
When I saw that video, I was like "something's not right here". How can it be so fast on the lap when it’s so slow on the straight. And where’s the tyre noise, or G-force meter. And then we find out that after the record, the car was on special tyres. Come on guys…
And this is what Glickenhaus said:
I would love to see it. Lamborghini bring their Huracan, and I bring my little New York road car [his ex-race car has been converted to road use, and wears New York plates], and we’ll see who’ll go round the quickest.
It’s the only fair and real way to do it. This is what I think it needs. You get the trophy for a year, we engrave your name on it, next year if someone beats you, they get it. But it’s real. The same day, the same weather, the same amount of rubber. Then you guys aren’t driven frigging crazy by claims and videos. I don’t believe any of it.
To be honest it sounds like both got threatened by the record moving closer to their claims, Koenigsegg did at least admit they couldn't compete with the downforce of the Aston Martin Valkyrie
