After the Huayra Tricolore, Pagani has now revealed the Huayra R, a track-only hypercar, limited to 30 units. Some of the key changes over the road car include a naturally aspirated V12 engine.
The monocoque is built with composite materials such as Carbo-Titanium HP62-G2 and Carbo-Triax HP62. The front and rear subframes are made of chrome-molybdenum alloy steel for better crash performance. Overall, the chassis boasts a 51% increase in flexural rigidity and a 16% increase in torsional rigidity over to the road version. Pagani claims a dry weight of just 1,050 kg (2,315 lbs).
As for the aerodynamics, the engineers apparently targeted a 1,000 kg of downforce at 320 km/h (2,205 lbs at 199 mph) and a ground clearance that allows maximum aerodynamic performance. “An ambitious goal, but one that was quickly achieved with excellent results right from the first aerodynamic tests, during which the car showed great stability and balance in line with the set target of 46%-54% downforce distribution throughout the entire speed envelope while maintaining reduced sensitivity to ground clearance,” Pagani said.
The suspension system is mostly made of forged aluminium alloy, comprising independent double wishbone with helical springs and electronically controlled active shock absorbers. Braking duties are handled by ventilated carbon-ceramic discs measuring 410 × 38 mm at the front and 390 × 34 mm at the rear, both gripped by 6-piston calipers. The 19-inch forged aluminum alloy wheels are wrapped with specially developed Pirelli P Zero slicks.
Replacing the Mercedes-AMG 6.0-litre twin-turbo V12 is a 6.0-litre naturally-aspirated V12 racing engine, co-developed with HWA AG — a company spun off from Mercedes-AMG long ago. HWA stands for Hans Werner Aufrecht, one of the founders of AMG. The engine pumps out 625 kW (850 metric hp) at 8,250 rpm and 750 Nm (553 lb-ft) of torque from 5,500 to 8,300 rpm. The engine revs up to 9,000 rpm. The gearbox is a 6-speed sequential, also co-developed with HWA AG. The engine and the gearbox weigh 198 kg (436 lbs) and 80 kg (176 lbs), respectively.
Price? Starts at €2.6 million plus taxes.
