Evidence for this added potency comes with the number of new aerodynamic pieces added to the exterior. Up front, there’s a significantly larger front splitter that rivals that fitted to the McLaren Senna, while at the back a new rear wing is held in place by two curved arms and a centre arm.
The car also sports new a dual-pipe exhaust system that blows engine waste gases out through the middle of the back end, rather than in the centre of the diffuser like the SV. This new technique, also used by the Huracán Performante, enhances the diffuser’s effectiveness by removing exhaust gases from an aerodynamically sensitive area.
Lamborghini has refrained from commenting on the pictures of the Aventador SV J development car, but Autocar understands that it will arrive later this year with a more powerful version of the Aventador S’s atmospheric 6.5-litre 12-cylinder engine.
The Aventador S, which arrived in the second half of 2017, produces 730bhp, 40bhp more than the previous version. Applying the same jump to the SV J suggests it could have an output of around 780bhp – that would make it one of the market’s most potent supercars. To put that figure into perspective, that’s 90bhp more the wild Porsche 911 GT2 RS has.
Backing the prospects of this extreme performance is the use of the letter J, which stands for Jota. Jota, the Spanish word for the letter J, 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 – 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, while the Miura Jota and a more recent Aventador J were produced just once each. This suggests Aventador SV J build numbers might be kept below the 600 units of the SV. If that’s the case, the SV J’s pricing would likely jump substantially from the original SV’s £321,743 starting figure.
