Lamborghini Sian Prototype takes to the Streets

A test mule of the Lamborghini Sian has been spotted on public roads, perhaps for the first time.

The Sian (LB48H) is Lamborghini’s first hybrid supercar. It’s also the world’s first supercar to use a supercapacitor-based mild-hybrid system.

The Sian borrows design cues from the Terzo Millennio concept, while the overall shape of the car is inspired by the Countach. The rear features three hexagonal LED lights and an active spoiler. The spoiler end plates are fixed to the bodywork. The car has an upswept rear diffuser with twin hexagonal exhausts.

The supercar is powered by a 6.5-liter, naturally aspirated V12 engine that produces 785 hp @ 8500 rpm and 531 lb-ft @ 6750 rpm. A 48 V electric motor adds another 34 hp and 28 lb-ft of torque, for a combined output figure of 807 hp. The mild-hybrid system uses a lithium-ion supercapacitor to store energy. The powertrain is hooked up to a 7-speed transmission and a Haldex all-wheel drive system.
