Le two variants of Lamborghini Sian, like the other 61 models, were made to order by the technicians of the Lamborghini Ad Personam department. As mentioned, the first model features the Nimbus Gray shade used for the bodywork and features an exposed carbon fiber roof with Mars Red accents. Inside, it benefits from a Black Hades look theme with contrasting Alala Red trim. As for the second, darker Sian supercar, there is no lack of an equally captivating design; the car's Helene Black bodywork is complemented by shades that recall Gold Electrum accents. Also in this case, the passenger compartment recalls the exterior thanks to a Black Ade leather upholstery with contrasting Gold Electrum stitching.
The car from the Sant’Agata Bolognese company features a 6.5-liter naturally aspirated 785 hp V12 combustion engine, the same one adopted by the Aventador SVJ, combined with a 48 Volt electric motor. To make Sian's driving even more exciting, a 34 HP electric powertrain connected directly to the axles has been integrated into the gearbox. The combined power, of 819 hp, allows the supercar to burn 0 to 100 km / h in 2.8 seconds and reach a top speed of 350 km / h.
One of the most important features of Sian is certainly represented by the supercapacitor, developed to store the electric energy of the hybrid unit and thus replace the lithium ion batteries. It is an energy storage system that is three times lighter than an accumulator of the same power and three times more performance than a battery of the same weight.
