Lamborghini has taken the wraps off its Aventador SVJ, production of which will be limited to 900 units. Even before its unveiling, the Superveloce Jota was already in the news, having secured the honour of being the new Nürburgring production car lap record holder, completing the 20.6 km-long course in six minutes 44.97 seconds last month with Marco Mapelli behind the wheel.

The SVJ gets a visual enhancment in appearance compared to the Aventador S, but the changes are very much designed for go as they are for show – the result is a significant improvement in downforce compared to the previous Aventador SV, with a 40% gain on both axles as well as an improved drag coefficient to boot.

Changes include a new front bumper with integrated side fins and new air intakes, which help reduce drag and improve overall cooling. Other airflow enhancements come in the form of a new front splitter and a tri-dimensional air outlet on the hood.

The aero design of the underbody has also been revised, with vortex generators working in conjunction with the front diffusers and a new, extreme-design diffuser on the Omega-shape rear bumper.

Other rear enhancements include a new carbon-fibre wing with a new air foil as well as side winglets, which help to reduce turbulence while providing high downforce. There’s also a new rear engine bonnet, made from carbon-fibre and removable via quick release clips.

The SVJ also gets a revised, high-mounted naked exhaust, helping to shed weight off the car, and there’s of course the Aerodinamica Lamborghini Attiva (ALA) system, in a new ALA 2.0 configuration.

First seen on the Huracán Performante, the ALA system actively varies aero load to achieve high downforce or low drag, depending on dynamic conditions – electronically-actuated motors open or close active flaps in less than 500 milliseconds in the front splitter and on the engine bonnet that steer the air-flow, front and rear. For the SVJ, the package has been enhanced with recalibration and new optimised air inlets and aero channel elements.

There’s also aero vectoring at the rear for high speed cornering, courtesy of the rear wing’s split left-right inner air channel – depending on the direction of the turn, the ALA can be to instructed to be switched on in either the right or left side of the wing, increasing downforce and traction on the inner wheel and improving dynamic stability.

The marque’s normally-aspirated 6.5 litre V12 has been given some modifications, and these include a new titanium intake valve with a new-shape intake runner and length as well as a modified intake cylinder head duct for a higher flow coefficient. The seven-speed Independent Shifting Road (ISR) gearbox has also been recalibrated for the application in the SVJ.

The improvements to the mill translate to a slight bump in power and torque, in this case 770 hp at 8,500 rpm and 720 Nm at 6,750 rpm, 30 hp and 30 Nm more than on the Aventador S. Power continues to be sent to all four corners, and performance figures for the 1,525 kg offering include a 0-100 km/h time of 2.8 seconds (0-200 km/h in 8.6 seconds) and a top speed of more than 350 km/h.

Elsewhere, the SVJ’s LMS suspension has been recalibrated to improve body and wheel control with a focus on track performance, and features a 15% higher damping force range over the SV. It also gets 50% stiffer anti-roll bars compared to the Aventador SV.

Other items that have been reworked for utilisation in the SVJ are the ESC, ABS, rear-wheel steering (LRS) and four-wheel drive system, the latter offering an additional 3% of torque to be sent to the rear axle compared to the SV. The power steering also features changes, rebalanced and tweaked to improve steering precision and provide natural feedback.

As standard, the Aventador SVJ comes equipped with super-light ‘Nireo’ alloys designed specifically for it, and these are wrapped with specially-developed Pirelli P Zero Corsa tyres with a specific tread design. Aside from enhanced grip, the new rubbers provide higher vertical stiffness to accommodate the car’s higher levels of downforce.

Optionally, there’s a ‘Leirion’ alloy with ‘Y’ and hexagonal details as well as street-legal Pirelli P Zero Trofeo R tyres, the latter for track use. Another item on the options list is a Lamborghini telemetry system to record lap times and track performance stats.

The Aventador SVJ also gets a special edition called the SVJ 63, which was unveiled at the Pebble Beach Concours. Paying homage to the company’s founding year of 1963 and heavily decked out in carbon-fibre, the car will be produced in an additional limited number of 63 units. Deliveries of the Aventador SVJ are slated to begin next year.
