Limited to just 800 units worldwide, the drop-top Aventador SVJ has been unveiled, sporting the same power, performance and technologies as its coupe-bodied twin.

Lamborghini has revealed the Aventador SVJ Roadster for the Geneva motor show this week, which the company says brings "exclusive open air driving perfection".

As expected, the convertible version of the Raging Bull's flagship draws upon the coupe's mechanical and aerodynamic package, while swapping out the fixed hard roof for removable carbon-fibre panels that can be stowed in the 'frunk' – or front trunk, if you will. (Not that we call it a trunk here... - Ed.)

Weighing in at 1575kg, the SVJ Roadster is just 50kg more than the coupe. The slight increase in heft means the convertible is fractionally slower than the hard top, with 0-100 taking a claimed 2.9 seconds (up 0.1 seconds), while 0-200 takes 8.8 seconds (up 0.2 seconds).

Power comes from the same 6.5-litre naturally-aspirated V12 as the SVJ coupe, tuned to deliver 566kW (770hp) at a screaming 8500rpm, and 720Nm of torque at 6750rpm.

Lamborghini reckons the SVJ Roadster will still rush to "more than 350km/h" like the coupe, while it's capable of braking from 100km/h to zero in 31 metres courtesy of the massive 400mm front and 380mm rear carbon-ceramic brakes with six-piston front and four-piston rear calipers.

An array of active aerodynamics systems help the SVJ Roadster to carve up corners just like its hard-topped twin – dubbed Aerodinamica Lamborghini Attiva 2.0.

There's active flaps in the front splitter and rear wing that constantly monitor conditions to react in less than 500 milliseconds to "ensure the best aerodynamic set-up in every driving condition".

When 'off', the flaps are closed and the carbon rear wing acts as a traditional fixed wing to generate maximum downforce for high-speed cornering and full brake conditions.

Conversely, having ALA 'on' opens the active flaps, reducing air pressure on the front spoiler and directing air flow via an inner channel and through the "specially-shaped vortex generators" on the vehicle's underside, while also opening flaps in the central pylon to 'stall' the rear wing, reducing drag and optimising conditions for maximum acceleration and top speed.

There's also an aero vectoring system as per the coupe, which directs air either side of the rear wing depending on the direction of the turn to increase downforce and traction on the inner wheel, optimising the chassis' momentum and reducing the required steering angle, "improving the car’s overall dynamic stability".

Other upgrades compared to the 'standard' Aventador S Roadster include larger side intakes and front side fins to improve airflow, aid cooling and reduce drag. Overall, the drop-top SVJ sports 40 per cent more downforce than the previous Aventador SV Roadster.

The engine gets a titanium intake valve, a newly-shaped intake runner and modified intake cylinder head duct for 'higher flow coefficient'. A high-mounted lightweight naked exhaust produces "the most emotive sound" from the V12 engine, too.

Under the skin there's also rear-wheel steering for enhanced high-speed stability and cornering agility while also reducing braking distance, according to Lamborghini, along with model-specific tunes for the steering, transmission, all-wheel drive, ESC and ABS systems.

Anti-roll bar stiffness has been improved by 50 per cent compared to the Aventador SV, while the 20-inch front and 21-inch rear alloy wheels are shod in Pirelli P Zero Corsa tyres that were specifically designed for this model. Track-focused Pirelli P Zero Trofeo rubber is optionally available.

In addition to the removable roof, the SVJ Roadster uniquely gets an electrically-operated rear window which acts as a wind deflector when closed. When open, it "amplifies the unique sound of the naturally-aspirated V12 engine" – we know what setting we'd leave it in.

The TFT driver's instrument binnacle features special graphics showing the status of the various ALA functions in real-time, while Apple CarPlay is available as a no-cost option for the central navigation system.

"Almost 250 colours" are available to customise your SVJ Roadster, including the matte bronze you see here. The company's Ad Personam program offers "virtually limitless" specification options, with every single leather and Alcantara part configurable upon customer demand.

First deliveries in Europe will commence in the northern hemisphere's summer (June-August) 2019, with pricing to kick off at €387,007 ($618,724.03).

Australia

CarAdvice has contacted Lamborghini's local division regarding Australian availability and pricing, and is awaiting a response.

The coupe retailed for a hefty $949,640 plus on-roads when it went on sale in August last year, so if offered locally we'd expect the SVJ Roadster to nudge, or even eclipse the $1 million mark.
