Meet the Siån, a limited-run evolutionary step of Lambo’s V12 lineage. It’s also the fastest and most powerful car to ever come out of Sant’Agata Bolognese. Yep, it’s official: Lambo has gone hybrid. But not as you’d imagine. As everyone else in Car World is starting to embrace smaller capacity engines, turbocharging and fully-electrified drivetrains, Lamborghini is still clinging onto its beloved 12 cylinders like Gollum’s precious. And not just clinging onto them, but juicing them with supercapacitor technology (jeez, that sounds cool) to make the fastest and most powerful Lamborghini ever. This sounds like our kind of progress.

Let’s start with the name. Siån. It translates as ‘flash of lightning’ in Bolognese dialect. But with that funny squiggle, you may be thrown as how to say it. Sy-anne? See-an? Well, it’s pronounced ‘Shh-ahnn’. Sounds a bit like a receptionist at your local recruitment centre. In reality, it’s a lot more exciting than that – having pinched tech from the Lamborghini Terzo Millennio.

That was Lambo’s electric hypercar concept from a few years ago. A supercar from the third millennium, one built in conjunction with the brainiest of brainboxes from the Massachusetts Institute of Technology. Now some of its crazy tech has been distilled and drip-fed into the local recruitment centre receptionist – sorry, we mean the Siån – specifically the supercapacitors. The main advantages of supercapacitors compared with standard batteries is their ability to store up to 100 times more energy, their capacity to accept and deliver charge much faster and to tolerate many more charge and discharge cycles. In short, they’re lighter and more energy-dense than lithium-ion batteries.

The Siån uses a supercapacitor that is three times more powerful than a battery of the same weight, and three times lighter than a battery producing the same power to feed a 48-volt e-motor, delivering 33bhp. Like other mild hybrid systems, it has been incorporated into the gearbox, but this is the first application where a low-voltage hybrid has a direct connection between the electric motor and wheels. Meaning the e-motor can take the strain during low-speed manoeuvres.

More importantly, it helps feed that big 6.5-litre V12 engine from an Aventador. A V12 that now incorporates titanium intake valves and has been turned up to 774bhp at 8,500 rpm – the highest output ever. So combined with the additional 33bhp from the hybrid system, we’re talking 807bhp fed through all four wheels to give a 0-62mph time in under 2.8 seconds and a top speed of 217mph. There’s also a regenerative braking system. Because supercapacitors are better at charging and discharging than conventional batteries, the Siån’s energy storage system is fully charged every time the vehicle brakes – not gradually. It can then be utilised straight away as a torque boost up to 130 km/h and fill in the torque vacuum between gearchanges for a cleaner shift. Oh, and the noise? With that V12, it'll have bucket loads of goodness in that department – don’t you worry.

But look at it. It’s a real evolutionary step on for Lamborghini’s design language, one that safely bats off the critics that believe Lambo has got boring and will no doubt inform the next Aventador. This is proper wild-as-you-like poster car stuff from a designer who seemingly had nothing but a diet of Lucky Charms and Red Bull. Finished in Ninja Mutant Turtle green accented with gold, it’s more rakish and predatory than an Aventador but upholds some heritage design cues such as the Gandini line from the Countach. There’s also plenty of Lambo ‘Y’ shapes. Go on, count them all: in the NACA air inlets on the doors, the glass elements in the engine cover, the diagonal line in the front hood and the ‘Y’-shape headlights, pinched from the Lamborghini Terzo Millennio.

As you can see, there are plenty of nods to the Countach, too. The swept up rear that flows into the ‘hexagonita’ design and six hexagonal tail lights inspired by the 80s supercar. Inside there’s more, including a ‘Periscopio’ tunnel that originally incorporated a rear mirror in the Countach and familiar Aventador switchgear. But there’s a new, big portrait TFT screen. And people like screens. Just go on any Tesla forums. Outside, the aerodynamics have also been optimised resulting in a sleeker, more efficient design. It’s properly sharp. Naturally, airflow is sent through front splitters but also now through the front bonnet. It’s then directed around the side to the intakes (to help cooling) and then over the rear spoiler. Like the Aventador, the spoiler is retractable to offer a flush line when static, however, there are fixed carbon endplates.

Only 63 Siåns will be made (which, in Lambo limited runs, is quite a lot when you consider the Veneno, Aventador J etc) and they’re all accounted for. How much they paid for the privilege won’t be disclosed, but we’re guessing many, many millions of monies. Either way, Lambo’s V12 ain’t dead yet. And this is just the start of the iconic Italian supercar manufacturer’s hybrid chapter. Where it’ll go from here, we’ll have to wait and see.
