0-100km/h is done in 0.9 seconds. 0-300km/h takes just 3.6 seconds. And here's the kicker: the company lists 0-600km/h acceleration - 7.0 seconds.
The Mazda 787B's R26B was 2.6L making 700hp. Theoretically then 5.2L could make 1400hp. Throw on 4 turbos and 2800hp is possible. Although I wouldn't trust it to be the most daily drivable and would question reliability.

Those acceleration numbers are absolutely ridiculous. If anyone has paid attention, even though HP numbers have doubled in the last 5 years for supercars 0-60 times haven't changed. The biggest factor in acceleration at this point is GRIP. You can triple your power and not change your 0-60 because you didn't increase your grip.

I am not following your "calculations". Even if it was linear acceleration force it would take 5.4 seconds to hit 600km/h based on their 0-100km/h. (600 is 6 times 100 therefore 0.9x6 = 5.4s)
But as we know, acceleration is never linear. The faster you are going the slower you accelerate due to less torque and more wind drag. But see what I said above anyways, their time is way off reality.

I know who he is, thats why I asked him.
No offence kevin. But time is not calculated by multiplying with 6.
And also I didn't consider other aspects.

First off, I have never worked at SSC, although I would love to.

Second, I am just wondering how you came up with your calculations. I am not attacking you, I just can't find any way to possibly get what you got. Even my clearly wrong, underestimated x6 calculation is slower than yours.
And you can multiply time by 6. Time is a linear unit. So is distance.

I'm sorry but yes, you have worked at SSC and you are an expert in vehicle dynamics because someone said it on the internet.

Accept your fate.
