Koenigsegg confirmed on their Facebook page that the One:1 has set a lap time of 2:33.26 around Spa-Francorchamps and then Shmee150 mentioned on his page that is is faster than the holy trinity of hypercars.
“Supposedly 5 sec faster than a McLaren P1, 7 sec faster than a Porsche 918 Spyder, 15 sec faster than a Ferrari LaFerrari, the Koenigsegg One:1 did a 2:33:26 lap on the Spa Francorchamps F1 Circuit…” – Shmee150
