The Huayra BC is a track focused version of the Huayra which was unveiled at the 2016 Geneva Motor Show. The Huayra BC is named after the late Benny Caiola, a friend of Horacio Pagani, and the first Pagani customer. The Huayra BC has an improved version of the standard Huayra's 6.0 L twin-turbocharged V12 engine having a power output of 755 PS (555 kW; 745 hp) as well as 1,100 N⋅m (811 lbf⋅ft) of torque. The dry weight is reduced by 132 kg (291 lb) to just 1,218 kg (2,685 lb), thanks to the use of a new material called 'carbon triax' which Pagani claims is 50% lighter and 20% stronger than regular carbon fibre, giving the car a power-to-weight ratio of 1.62 kg (3.57 lb) per horsepower. The Huayra BC comes with a lighter titanium exhaust system, new aluminum alloy wheels, and a stripped out interior. The tires are Pirelli P-Zero Corsas that feature 12 different rubber compounds, and the suspension and wishbones are made of aeronautical grade aluminum, known as Avional. The Huayra BC also has a new front bumper with a front splitter and winglets, deeper side skirts, and an air diffuser that stretches the entire width of the rear bumper with a large rear wing. All of the exterior components in the car are used to optimize downforce and drag. The Huayra BC uses an all-new Xtrac 7-speed sequential manual transmission. Pagani has stuck with a single-clutch gearbox because it weighs 40% less than double-clutch gearboxes. All 20 units of the Huayra BC coupé have been sold out.
