Discounting barely-legal track cars from Radical, whose LMP-style pseudo-racers top the time charts, the Porsche 918 Spyder holds the record as the fastest street-legal production car ever to lap the Ring at 6:57. A blindingly fast lap time, to be sure, but the 918 isn't the only new hybrid hypercar in its class. According to official factory statements, the McLaren P1 has lapped the winding German circuit in under seven minutes. And rumor has it that its actual lap time, though not confirmed, was clocked at 6:47. That would already make it considerably faster than the Porsche, but that's not the end of the story.
According to an unnamed inside source cited by Autocar, the P1 has actually lapped the Nürburgring in "six minutes 30 something." That would make it nearly half a minute faster than the Porsche, and a good ten seconds quicker even than the Radical SR8 LM. For its part, McLaren has yet to confirm the time, but we're sure it will in due course.
For that matter, though Maranello has tested the new LaFerrari to the track, it has yet to announce any official time. But with the gauntlet thrown down, we wouldn't be surprised to see a scarlet-clad test team heading north to Germany in the near future. The last time they did, they clocked a 6:58 lap time with the 599XX, but while production-based, that car was never meant to drive on public streets.
