Pagani Huayra + 99 bhp - 150 kg = Huayra BC

So the first question we have is why BC? Why not something a bit sportier? The Italians explain in due course that it stands for Benny Caiola, one of Pagani's first customers.

No more than 20 of these hypercars will be produced, but they have all been sold already. And at an eyewatering price of $2.8 million (just over £1.9 million).

So you would hope that Pagani have pulled out all the stops to justify its hefty pricetag, no? Well the Mercedes-AMG-sourced 6.0-litre bi-turbo V12 engine jumps up to 819 bhp. Torque figures haven't leaked yet, although there's bound to be an increase over the already sufficient 1,000 Nm. The regular Huayra charges to 60 mph in 3.3 seconds, so we have good reason to expect a sub-3.0 second time for the BC.

Other than engine modifications, the Italian hypercar has been on a detox and lost 150 kg. The front and rear fenders have been tampered with, with larger air intakes up front, and are joined by aerodynamically designed side skirts. A new rear wing will also provide 500 kg of downforce at 155 mph, aided by active flaps.
