Lamborghini Sian 2020: Electrified V12 feeds the fastest Lambo of all time

A little hybrid help makes the Sian the fastest Lamborghini of all time.

The fastest Lamborghini of all time has been revealed, with the Sian calling on a little hybrid help to claim the Raging Bull's top honours.

That's not to say the Sian has abandoned fuel altogether, of course. This is still a Lamborghini, after all, and so the Sian still gets the brand's fire-breathing V12 engine, only this time - and for the first time - it's paired with an electric motor. 

The V12 has been tweaked to be the most powerful Lamborghini has ever produced. The V12 has been tweaked to be the most powerful Lamborghini has ever produced.

The result is a vehicle that is staggeringly powerful; the V12 has been tweaked to be the most powerful Lamborghini has ever produced, now good for 577kW, while a 48 volt e-motor (the Sian is what is termed a 'mild hybrid') adds around 25kW on take-off, boosting total system output to a staggering 602kW.

Those outputs have the exact effect on performance figures that you'd imagine. Lamborghini says the Sian is the fastest car its ever produced, able to clip 100km/h in "under 2.8 seconds", and will push on to a screaming 350 km/h.

“The Sian is a masterpiece in possibilities,” says Lamborghini Chairman, Stefano Domenicali. “Not only does the Sian deliver a formidable hyper car design and engineering tour de force today, it augments the potential for Lamborghini as a super sports car brand for tomorrow and for decades to come, even as hybridiaation becomes more desirable and inevitably essential.

The Sián represents the first step in Lamborghini’s route to electrification. The Sián represents the first step in Lamborghini’s route to electrification.

"The Lamborghini Sián represents the first step in Lamborghini’s route to electrification, and expedites our next-generation V12 engine."

Reading between the lines, Domenicali is saying the Sian - which translates to 'flash' in the Bolognese dialect of the brand's home in northern Italy - is the torchbearer for the electrified Lamborghini's to come, with hybrid tech able to prolong the shelf life of that iconic V12 engine. 

The Sian is also home a clever regenerative braking system that recharges the vehicle's batteries in full every time the driver brakes. It means the extra power - which assists the traditional engine up until 130km/h - is almost always available.

The Sian is limited to just 63 vehicles - all of which have already been sold.

Now the bad news; the Sian acts a canary down the electric coalmine for Lamborghini, and as such is limited to just 63 vehicles - all of which have already been sold.

"The 63 individuals worldwide will own not only the fastest, but a unique Lamborghini,” says the brand's head of design, Mitja Borkert.

But equally important, the Sian is anything but a flash in the pan, with more electric Lamborghinis sure to follow.
