Video footage taken from on board the new Lamborghini Aventador Superveloce Jota proves that this supercar is the fastest-ever production car to lap the Nürburgring Nordschleife. The video shows the upcoming SVJ completing the lap in a time of 6min 44:97sec – making it 2.27sec faster than the Porsche 911 GT2 RS. It’s also just under 15sec faster than the Aventador SV. This successful record attempt was set by Lamborghini factory driver Marco Mapelli.

A report leaked ahead of official confirmation of the lap time claimed that the range-topping Lambo  produces 769hp from its 6.5-litre V12 – 69hp more than the 700hp GT2 RS and 20hp more than Lamborghini's current flagship, the Aventador SV.

The Italian supercar maker will officially reveal the Aventador SVJ at the Monterey Car Week next month. An ever-increasing number of teaser videos have been posted online promoting the same. Previously released videos have boasted about the car having “the best aerodynamic efficiency” and claims of class-leading power-to-weight ratios have also been made.

At the front, there’s a significantly larger front splitter than the one fitted to the McLaren Senna, and a new rear wing is held in place by two curved arms and a centre arm.

The car also sports a new dual-pipe exhaust system at the middle of its back-end, rather than in the centre of the diffuser, like on the SV. This new technique – which is also used by the Huracán Performante – enhances the diffuser’s effectiveness by removing exhaust gases from an aerodynamically sensitive area.

The Aventador S arrived in the second half of 2017 and produces 740hp – 40hp more than the previous version. Applying the same jump to the SV J suggests it could have an output of around 791hp, making it one of the market’s most potent supercars. To put that figure into perspective: that’s 91hp more than the previous Nürburgring record-holder, the Porsche 911 GT2 RS.

Backing the prospects of this extreme performance on the Aventador is the use of the letter J in its nomenclature. The J – which stands for Jota – has been applied to some of Lamborghini’s most hardcore models, including race-homologated versions of the Miura and Diablo. Although the Aventador will not compete in motor racing — since Lamborghini’s competition efforts are focused on the lighter Huracán — it emphasises the car’s abilities.

Jota models have a history of being produced in extremely low numbers. No more than 28 Diablo Jotas exist, and just one each of the Miura Jota and a more recent Aventador J were produced. This indicates that the Aventador SV J build numbers might be kept below that of the SV; less than 600 units.
