Lo and behold, the Lamborghini Sian Roadster has arrived. It’s a limited-edition open-top hybrid super sports car engineered around Lamborghini’s iconic V12 engine, with unique hybrid technologies. The 6.5-litre, naturally-aspirated V12 produces 774bhp at a staggering 8,500 rpm. Add to that the 48-volt mild-hybrid system, which uses a small electric motor incorporated into the gearbox gives an additional 33bhp power boost. That takes the Sian Roadster to an insane 807bhp. 0 – 100kmph comes up in just 2.9 seconds and top speed is over 350km/hr! That’s not all, Lamborghini will build on 19 of these open-top road rockets, all of which are already sold. Also, if you’re wondering, ‘Sian’ in local Bolognese dialect, meaning ‘flash’ or ‘lightening’, which denotes the Sián Roadster’s electrification as part of the company’s future hybrid strategy.
“The Sian Roadster encapsulates the spirit of Lamborghini,” says Stefano Domenicali, Automobili Lamborghini Chairman and Chief Executive Officer. “It is the expression of breathtaking design and extraordinary performance, but most importantly embodies important future technologies. The Sian’s innovative hybrid powertrain heralds the direction for Lamborghini super sports cars, and the open-top Sián Roadster affirms a desire for the ultimate lifestyle, Lamborghini, as we move towards a tomorrow demanding new solutions.”
The Sian Roadster sports Lamborghini’s innovative supercapacitor application – a world-first technology storing ten times the power of a lithium-ion battery. Located in the bulkhead between the cockpit and engine it ensures perfect weight distribution. As a result, it’s three times more powerful than a battery of the same weight and three times lighter than a battery producing the same power, the electric system with the supercapacitor and e-motor weighs only 34 kg. Symmetric power flow ensures the same efficiency in both charging and discharging cycles: the most lightweight and efficient hybrid solution.
The Lamborghini Sian Roadster also incorporates a regenerative braking system. The symmetric behaviour of the supercapacitor, which contrary to normal Li-Ion batteries can be charged and discharged with the same power. As a result, the energy stored is an instantly-available power boost. After that, the driver to draw immediately on increased torque when accelerating away, up to 130 km/h when the e-motor automatically disconnects.
Folks at Lamborghini say that the Sian Roadster takes its design cues from a coupe without having to comprise the open-air cabin feel. The Sian’s long sculptured contours and characteristic aero wings give the roadster a strong profile. The car’s very low front, with integrated carbon fibre splitter, houses the iconic Lamborghini Y-shape headlights. The rear of the car incorporates Lamborghini’s evocative hexagon design, including six hexagonal taillights inspired by the Countach. There’s an excitement that every Lamborghini brings with it, almost every time. What do you think of the Sian Roadster? Is it bonkers enough to be a poster on your wall?
