Limited-edition model saves the brand’s V12 with supercapacitor technology.
Is this an all-new Lambo?
This is the Lamborghini Sian, a limited-edition model that will make its world debut at next week’s Frankfurt motor show.
Largely based on today’s Aventador, the Sian comes with an exclusive body work featuring several distinctive design details on the front, rear and sides of the car.
The Sian’s interior also gets a slightly different theme, although some elements like the steering wheel and dashboard structure is shared with the Aventador.
Only 63 Sians will be made worldwide and all are already sold out with each costing a few hundreds of million baht if sold and taxed fully on Thai shore.
Lamborghini freely says the technology appearing in the Sian is previewing the future for the brand’s V12 to be used in the all-new replacement of the Aventador due in around two years.
Although the Aventador (and Sian) uses a single-clutch automatic gearbox, top engineers once told us that the replacement will get the smoother twin-clutcher apart from a hybrid V12 to reduce emissions and increase performance at the same.
And what exactly does that tech do?
To keep things as simple as possible, supercapacitors are used in place of the widely used lithium-ion battery. Its energy comes from braking deceleration and can used for short bursts of overtaking power.
Lamborghini says supercapacitor tech is more powerful and lighter by three times in both cases than lithium-ion by weighing just 34kg. A 48V electric motor is placed in the transmission.
The Sian has taken the Aventador SVJ’s 6.5-litre V12 and pumped its power up from 770hp to 785hp thanks to the use of titanium intake valves. And together with 34hp electric motor, combined output rises to 819hp.
As a result, the Sian goes from 0-100kph in 2.8sec, the quickest time for a Lambo yet. That’s a tenth of second faster than the Aventador SVJ. Lamborghini stresses that the Sian has better mid-range punch as well but has yet to reveal the gains in efficiency.
