Leaked photos from several sources preview what is the most powerful raging bull in history: the Lamborghini Sian. Lamborghini followed up the leak by debuting the Sian online, revealing its spectacular design and impressive performance.

The 2020 Lamborghini Sian will make its public debut at the 2019 Frankfurt Motor Show next week. Suffice it to say that this Lambo is the firm’s crowning achievement- that is until the next one comes along.

Lamborghini regularly comes up with outlandish designs that instantly become wildly popular.

The Sian is Lamborghini's first car to feature electrification. What is more staggering is that there are 819 horses on tap, ready to unleash mayhem at a prod of the throttle.

Engine

Diving into the heart of the matter, the Lamborghini Sian is powered by the same 6.5-litre free-breathing V12 motor that powers the Aventador and all its derivatives (Aventador SVJ produces 770hp). Behind the seats of the Sian, however, the engine cranks out 819hp. Sian is also the first Lamborghini to embrace electrification, albeit in baby steps. It perhaps pays to be owned by Audi to have access to the mild-hybrid technology.

Power is sent to all the wheels through a seven-speed automatic gearbox featuring adaptive shift characteristics relying on the chosen driving mode. The electronic AWD system at the other end of the transmission also brings a rear mechanical self-locking differential to the table.

Performance

Lamborghini cars are renowned for their incredibly dramatic, brisk performance. The Sian is no different, extracting insane power from its V12, kept in check with equally impressive amounts of grip generated by that scythe-like body garnished with carbon fibre. In the sprint to 100kph, both Sian and SVJ post identical times at 2.8 seconds.

Keep the pedal to the metal past the ton, and the Sian will substantially disappear on the SVJ, accelerating 1.2 seconds faster from 70 to 120kph. Beyond that, it just goes on relentlessly, gaining more ground on the SVJ. This feat is nothing short of incredible, considering that SVJ is no slouch in the first place. Top speed is electronically limited to 350kph, probably because the Sian might take its driver into orbit if pushed too much.

Any adjective you choose falls utterly short of describing the Lamborghini Sian's design. We'll stick with jaw-dropping for now.

Design

The Lamborghini Sian is modelled heavily after one of the Italian carmaker’s radical concepts: Terzo Millenio. Of course, Lamborghini didn’t make the Sian as dramatic as the concept, but it still looks visceral and impossibly cool. The devil is in the details, and Lamborghini has nailed it all over. The six taillamp clusters, for example, mimic the shape of the exhaust tips.

Mitja Borkert, Head of Design at Lamborghini, said, “The fastest Lamborghini must be a visual and symphonic feast, as remarkable to those who see it pass by as those privileged to drive it. It takes inspiration from the Countach, but the Sián is a futuristic icon, not retrospective.”

Finally, what does that ‘63’ badge on the carbon fibre shark fins at the back signify? Well, just 63 units of the Lamborghini Sian will ever be produced. Obviously, all of them are sold out, despite starting at an eye-watering $3.6 million each.
