I think the One pretty much is a street legal F1 car tho.
I don't know, I think the Jesko is a game changer and will be the fastest one around the Nurburgring. 1,200hp on gas and 1,600hp on ethanol and the downforce it has is unheard of.
They both are. As I said it is designed by Formula 1 genius Adrian Newey, with no compromise. It has a naturally aspirated V12 that produces 1000bhp and revs to over 11,000rpm. It is more like an old skool Formula 1 engine from the 90s.
The One has a modern formula 1 engine (literally), which is kind of a hybrid.
And I don't think the Jesko will beat either the Project One or the Valkyrie on a track where aero is needed. On a fast circuit with few big corners it might have a chance, but where the track has a lot of corners where the aerodynamics is key, I'm not sure about that.
Another thing to point out, Adrian Newey was/is chief designer at Red Bull. They won the Formula 1 championship for 4 years in a row and this despite having one of the weakest engines. The power the engine didn't matter though because the aerodynamics of the car were far superior to any other car on the track. And that made up for it. The funny thing was, after 4 years of this, the rules changed making aerodynamics less effective (lol). Of course that pissed off Adrian Newey.
Anyway, there is more to aerodynamics than simply what in theory the car can produce in downforce. Pretty much every Formula One car (depending on what the rules allow) want as much downforce as they can create. That doesn't mean however, all formula one cars are equal when comes to aerodynamics though, hence Red Bull winning 4 years in a row with one of the weakest engines.
