Green on the Outside

Lamborghini Sian FKP 37 Hybrid Hypercar
The Lamborghini Sián FKP 37 is a V12 hybrid, green in color only.

With the Sián hybrid, Lamborghini has dipped its first toe in electrified waters. The result is not a shock.

Based on the Aventador SVJ, the Sián FKP 37 is similarly equipped with a furious 6.5-liter V12 engine, sports the familiar fighter-jet styling, and shares the active aero technology. So why does it cost over two million bucks more?

In a word, supercapacitor. Lamborghini’s first hybrid electric car is no plug-in. There are no heavy batteries adding weight to the formidable wedge of steel, titanium, and carbon fiber. Instead, a supercapacitor employs a regenerative braking system to generate energy, which it can store at lightning speed and discharge with similar immediacy.

For example, when braking into a corner the system charges the supercapacitor, which can then release the energy to the electric motor, adding an additional 34 horses for accelerating hard out of the corner. Although 34 horses don’t sound like much, the Sián produces over 800 horsepower in total, and the electric motor provides the additional boost when it is needed most.

Unsurprisingly then, the first Lamborghini hybrid has been designed purely for the sake of speed and will do nothing to improve fuel economy. Not that it matters to most of us because the Sián is a limited-edition showpiece that costs the same as a house in Beverly Hills.

Nonetheless, Lamborghini has invested heavily in researching both battery and supercapacitor technology with a view to extending the model lineup to include electric options, and today’s hypercar electric technology is likely to be driving the sports sedans of tomorrow. Expect Lamborghini to lead the way in building hybrid cars that will appeal to those of us who don’t really want one.
