The Huayra uses a twin-turbocharged 6.0 L (5,980 cc) M158 V12 engine developed by Mercedes-AMG specially for the Huayra, which produces 730 PS (720 bhp; 537 kW) at 5800 rpm and 1,000 N⋅m (738 lbf⋅ft) of torque at 2250-4500 rpm.[8] Its top speed is about 238 mph (383 km/h) and it has a 0-60 mph (97 km/h) acceleration time of 2.8 seconds. Using Pirelli tires, the Pagani Huayra is capable of withstanding 1.66 g of lateral acceleration at speeds of up to 230 mph (370 km/h). The Pagani Huayra uses a seven-speed sequential gearbox and a single disc clutch. The choice not to use a dual-clutch in an oil bath was due to the increase in weight of over 70 kg (154 lb), thus negating any advantage of the faster gear changes in a double-clutch transmission.[3] As a result, the entire transmission weighs 96 kg (212 lb). The car is equipped with Brembo brake calipers, rotors and pads. The calipers have four pistons in front and four in the rear. The rotors are drilled carbon ceramic, 380 mm (15.0 in) in diameter and 34 mm (1.3 in) thick.
