Limited Edition Lamborghini Sián Suggests Hybrid Future

Lamborghini is pointing to its electrified future with a hybrid hypercar it will debut at next week’s 2019 Frankfurt Motor Show (IAA).

The Lamborghini Sián will be limited to just 63 examples but the lucky few, who have already placed their orders, will enjoy a V12 gasoline 48-volt hybrid claiming a 0-62mph sprint of just 2.8 seconds on the way to a top speed in excess of 217mph.

The V12 engine, which incorporates titanium intake valves, delivers 783bhp at 8,500 rpm – the highest output ever from a Lamborghini power plant. Combined with the additional 32bhp from the mild hybrid system, the Sián delivers a total of 815bhp and enjoys a weight-to-power ratio better than that of the Aventador SVJ, achieved through extensive use of lightweight materials.

On the electrified side of things, its e-motor has been incorporated into the gearbox to improve response and performance with the automaker claiming it’s the first time in any low-voltage hybrid that a direct connection has been made between electric motor and wheels. The e-motor also supports low-speed maneuvers such as reversing and parking with electric power.

Lamborghini also claims a world first with its energy accumulation technology where the Sián uses a supercapacitor instead of a lithium-ion battery. The system was originally seen in the Lamborghini Aventador but has been dramatically improved to store ten times the power. It claims to be three times more powerful than a battery of the same weight and three times lighter than a battery producing the same power. Located in the bulkhead between cockpit and engine it ensures an ideal weight distribution. The electric system with the supercapacitor and e-motor weighs only 75-lbs. Symmetric power flow ensures the same efficiency in both charging and discharging cycles.

Maurizio Reggiani, chief technical officer, said: “With this car, we set ourselves the challenge of creating the best hybrid solution for a Lamborghini super sports car to provide us with the first step on our electrification strategy. With the Sián we are defining our route to innovation and we are setting new rules in new technologies, instead of just following existing solutions.”
