Lamborghini Sián review
£2,500,000

“Lambo at its wildest. Supercapacitor technology plays second fiddle to mighty V12, handling more fluent than you might expect”

Good stuff
Mesmerising V12, the noise, drama and exoticism, beautiful steering, chassis composure, wildness

Bad stuff
Much in common with the Aventador, negligible electric assistance, is there such a thing as too much noise?

What is it?

This is, by some distance, the most complicated car Lamborghini has ever produced. Yes, it’s shown us the Terzo Millennio with its batteries-for-body-panels and the V10 plug-in hybrid Asterion in the past, but both of those were pure concepts. The Sián is the first production Lamborghini to feature electrification. Which means you can actually buy one. Well, you could… they’re sold out, despite costing a spectacular £2.5m each.

But you’re unlikely to see two of them in your local multi-storey car park, because Lamborghini is only building 63 coupes and 19 roadsters. Numbers that pay tribute to the year Feruccio Lamborghini founded the company: 1963. In fact, there’s brown-nosing galore because the full name is Sián FKP 37: Sián (pronounced Sea-Ann, apparently) means flash or lightning in Bolognese dialect, the FKP bit is a nod to late VW Group chairman Ferdinand Piech and the 37 refers to 1937 – the year he was born.

It possesses a tuned version of the Aventador SVJ’s 6.5-litre, naturally-aspirated V12, producing 774bhp on its own – that’s already 15bhp more than the SVJ. To that is added another 34bhp of electrical oomph for a total of 808bhp, which is a lot. Enough for 0-62mph in less than 2.8 seconds and a top speed of around 220mph, claims Lambo.

This isn’t any old hybrid system either, it uses lithium-ion supercapacitors instead of a normal battery pack. Supercapacitors are interesting for several reasons: although they can’t hold as much energy as a regular lithium-ion battery of the same size and weight, they have three times the power density (the speed at which the energy is delivered) and can charge much more rapidly too. In other words the supercapacitors are fully topped-up every time you brake and therefore poised to torque fill during gearchanges, or add boost when you get back on the throttle. The upshot of all this is the supercapacitors don’t need to be big. The whole hybrid system weighs just 34kg – 1kg per horsepower added.
