Lamborghini Sián Roadster: World Premiere

Automobili Lamborghini presents the Lamborghini Sián Roadster: a restricted version, open-top hybrid tremendous sports activities automobile engineered round Lamborghini’s iconic V12 engine, with distinctive hybrid applied sciences. The roofless design of the Sián Roadster places an unique group of drivers in probably the most spectacular cockpits ever: all the time open to the sky; resonating with the inimitable V12 sound from essentially the most highly effective Lamborghini engine up to now.

The Sián Roadster sports activities Lamborghini’s revolutionary supercapacitor software: a world-first expertise storing ten occasions the facility of a lithium-ion battery. Located within the bulkhead between cockpit and engine it ensures good weight distribution. Three occasions extra highly effective than a battery of the identical weight and 3 times lighter than a battery producing the identical energy, the electrical system with the supercapacitor and e-motor weighs solely 34 kg, and delivers a weight-to-power ratio of kg/hp.

This superior expertise combines with the V12 engine, which contains titanium consumption valves and is uprated to 785 hp at eight,500 rpm. Combined with the extra 34 hp from the hybrid system, the Sián Roadster delivers a complete of 819 hp and reaches a high velocity of over 350 km/h.

The Lamborghini Sián Roadster incorporates a extremely subtle regenerative braking system, particularly developed by Lamborghini. The symmetric conduct of the supercapacitor, which opposite to regular Li-Ion batteries may be charged and discharged with the identical energy, totally expenses the Sián’s vitality storage system each time the automobile brakes. The vitality saved is an instantly-available energy enhance, permitting the driving force to attract instantly on elevated torque when accelerating away, as much as 130 km/h when the e-motor robotically disconnects, enhancing the elasticity maneuvers and making it greater than 10% quicker than a automobile with out this technique.

The revolutionary system additionally delivers instantaneous acceleration in low gears, with improved traction drive offered by the mixture of V12 engine and hybrid system. The Sián Roadster accelerates from zero to 100 km/h in lower than 2.9 seconds.

Want one? You’re too late. The Sián Roadster is restricted to simply 19 models, and so they’re all offered out.
