Video: watch a Pagani Huayra drift on ice

The Pagani Huayra BC is named after Horacio Pagani's first ever customer, Benny Caiola. It is a special edition, hardcore version, utilising that familiar 6.0-litre twin-turbo V12, here uprated to 789bhp and 811lb ft of torque. Plenty, then.

That V12 is piped through a titanium exhaust system that weighs just 2.9kg - 7.1kg lighter than before - with power sent through a single clutch auto 'box and out to the rear wheels.

Rear wheels that are kept in check by a special team working over at Bosch, who help develop safety and braking control systems for Pagani. And as part of the Huayra BC's testing, the company took a prototype out to some ice in Sweden. 

Cue lots of slow-motion sliding. "The philosophy of our vehicles is a combination between art and science, technology and design, performance and uncompromising safety," explains boss Horacio.
