0-300km/h = 24.7 seconds?
That's slower than the previous generation model. Their other two claimed metrics are or are near to a full one second off.
So their 0-300km/h is WAY off even if you use the Koenigsegg One:1 300-0km/h braking time in seconds wouldn't change. I'll see what else exists. But on that evidence, I'm not convinced I'll find anything, anywhere.
