Lamborghini has unveiled their first-ever hybrid supercar, the Sian.
Meaning “flash” or “lightning”, according to Lamborghini, the Sian is the first-ever electrified vehicle to come out of the Italian supercar maker. It mates the V12 powertrain of the Aventador with an all-new, never-before-seen hybrid system that uses a supercapacitor instead of a battery.
The big deal about this supercapacitor is that it's 3 times more powerful than a battery of the same weight thus making it far lighter than a traditional lithium-ion battery. Located in the bulkhead between the cabin and the engine, the supercapacitor combines with the sole electric motor to provide an additional 34 horsepower.
That electric motor is also extremely light and is integrated into the car's transmission in the same way that transmission manufacturer ZF is making their newer hybrid gearboxes. Lamborghini didn't say whether or not they made this new transmission in-house or if they acquired it from another manufacturer.
The Sian still uses the same 6.5-L V12 engine of the Aventador, but it has been tuned to produce 785 horsepower thanks to some titanium intake valves. That's a combined 819 horsepower with the electric motor, making this the most powerful Lambo ever made.
Zero to 62 mph (100 kph) takes just 2.8 seconds, while top speed is expected to exceed 217 mph. The electric motor is designed to help with low-speed acceleration and, reversing, and parking, and cuts out at around 81 mph. Regenerative brakes help keep the supercapacitor topped up.
Externally, the Sian bears some resemblance to the Terzo Millenio concept that Lamborghini unveiled back in 2018. The front fascia and headlights look the most like Lambor's electric concept, while the rear taillights have a hexagonal look that harkens back to the Countach.
Lamborghini plans to make 63 Sians, and if you don’t already have a production slot it’s already too late to buy one. A private function held last June apparently sold every one of these cars, sight unseen. Lamborghini didn’t provide a final sale price either, but an earlier rumor puts each Sian at around $3.6 million.
