The Lamborghini Sián hybrid supercar made its debut ahead of Frankfurt Motor Show, and it shocked us all. Appropriately named, “Sián,” which translates to “Lightning Bolt” in the Northern Italian dialect, it uses Lamborghini’s traditional V12 paired with supercapacitors. Smaller and lighter than any battery, “supercaps” can discharge all their power in an instant, adding 34 metric horsepower when needed.
Another advantage of the capacitors is that they are instantly charged every time the brakes are used. The power boost is available up to 80 mph if you need to merge onto the highway in style. Incorporated into the transmission is a 48-volt motor/generator for instant acceleration or braking. A panic stop will place a 600-amp load on the axles before the brake pads have time to react.
Converting their metric specs to SAE, the car has an output of 807 horsepower and 560 lb-ft of torque to the AWD system. This gives it a better power-to-weight ratio than the Aventador SVJ. While other brands have indicated that supercaps are a decade away, Lamborghini has charted a course for the future of hybrid power.
To create an electrifying style, their central styling department (Centro Stile) partnered with Lamborghini’s Ad Personam department. The reason for the inclusion of the custom shop is because only 63 cars will be built. The exterior of the prototype for the Sián that was unveiled in Frankfurt wore Verde Gea and Oro Electrum base coats with several layers of clear and metal flake.
The rear deck lid incorporates a quartet of heat extractors that are operated by “Smart Materials”. When the exhaust reaches a critical temperature, they open to keep the powertrain from a heat stroke. Why can’t all cars have this?
