There is no way a Laugher F70 LaF is doing 0-300 kmh in 15 seconds, maybe 17.5-18.5 with everything perfect and I mean perfect (vbox measured)
For the sake of accuracy
JoeTwinT had the 230+ mph EVOMS Porsche did 0-300 kmh in 14.1 seconds with 1500 bhp (vbox)
Tim941NYC 0-300 kmh with around 1600 bhp was under 14 s (vbox)
Agera R with uber straight line aero dynamics = 14.5 s and 1124 bhp and only 3200 lbs or so
I should add that a USA based LaF was weighed with fluids and 1/2 tank of gas (EU curb weight) at over 1600 kgs recently.. This is the car for sale I believe by some software exec
