Sant’Agata Bolognese, Italy - Lamborghini’s striking new Sián supercar is not only the most powerful production car in the marque’s history, but it also ushers in a new era of hybrid electrification.
Fittingly, its name departs from the tradition of fighting bulls, with Sián signifying a lightning flash in Bolognese dialect. That’s pretty much the way it will hit the market too, as only 63 of them are going to be produced and, sorry, but they’re all sold out already.
Let’s get straight to the numbers. Billed as the first step on Lamborghini’s road to electrification, the drivetrain mates a 48-volt electric motor, mounted inside the gearbox, to a V12 engine that churns out 577kW at 8500rpm. With the additional boost from the e-motor, the car boasts a system output of 602kW, which is enough to get it from 0-100km/h in just 2.8 seconds, according to claims, and reach a top speed of over 350km/h.
But here’s a little twist. Instead of using a lithium-ion battery to story power, the Sián employs a supercapacitor, which is said to be capable of storing three times more power than a conventional battery of the same size and weight.
The supercar has an advanced regenerative braking system, which thanks to the symmetric behavior of the supercapacitor, can be fully charged every time the vehicle brakes. This translates into an instant power boost that’s available up to 130 km/h, when the electric motor automatically disconnects.
