Update: Lamborghini has responded to our inquiry, clarifying the lap record:

'The Revuelto SV set its lap time on the Hockenheim Grand Prix circuit, using the same layout on which the Mercedes-AMG One recorded its time.

However, our claim refers specifically to the Revuelto SV as the fastest production super sports car at Hockenheim. The AMG One is a limited-production hypercar, with a fundamentally different technical concept, production volume and price positioning.'

The Revuelto SV lapped the Hockenheimring in 1:41.6.

Behind the wheel of the still-camouflaged prototype was Lamborghini factory driver and test driver Marco Mapelli.
