Driver Marco Mapelli was at the wheel for the 6:44.97 lap, which is more than two seconds quicker than the best time achieved by Lars Kern in the Porsche last year.
The Aventador SVJ achieved an average speed of 183km/h during its record lap of the 20.6-kilometre Nordschleife circuit.
Scarred by claims of fudged lap times with previous record holder, the Huracan Performante, Lamborghini stressed the record run was conducted with multiple independent witnesses.
“The challenge was managed by Lamborghini’s Research and Development team, with extensive tyre support from Pirelli technicians and driver,” the press release states.
“Fitted with cameras inside and out and full telemetry, under the formal scrutiny of Remak personnel who managed time and GPS certification using VBOX-Racelogic instrumentation, the lap attempt of the Aventador SVJ was performed during an exclusive session on the Nurburgring Nordschleife.”
The SVJ is no normal V12-powered supercar, and is expected to be the final farewell for the Aventador name.
However, Lamborghini is yet to officially reveal the car – which will wear the Jota suffix – so technical information is thin on the ground.
It’s clear from the camouflaged bodywork that the SVJ will have extreme aerodynamic additions, and according to Top Gear, a removable – not hinged – bonnet.
It has been reported the SVJ has 40 percent more downforce than the hard core Aventador SV, but one percent less drag, with 490kg of downward pressure at top speed.
The mid-mounted 6.5-litre naturally aspirated engine has been tuned to produce 566kW at 8500rpm, and 720Nm at 6750rpm.
“[The SVJ’s] tenure as the Nurburgring lap time record holder, even before its unveiling during the Monterey Car Week in California in August, endorses Lamborghini’s competence in applying superlative design engineering and ground-breaking technologies,” Lamborghini Chairman and Chief Executive Officer, Stefano Domenicali said.
“The SVJ is a super sports car at the zenith of performance, while also ensuring unrivalled driving pleasure.”
