Performance
The Huayra uses a twin-turbo Mercedes-AMG 60° V-12 engine.[3] The Huayra's 6.0-litre engine, the M158, produces over 700 horsepower and 1,000 N·m (740 lb·ft) of torque. Its top speed is 230 mph (370 km/h) [1] and it has a 0–60 miles per hour (0–97 km/h) time of 3.3 seconds.[1] Using Pirelli tires, the Pagani Huayra is capable of withstanding 1.5g of lateral acceleration at speeds of up to 230 mph (370 km/h).[3]Unlike many modern sports cars, the Pagani Huayra does not use a dual-clutch gearbox; instead it uses a seven-speed sequential gearbox and a dual-disc clutch.[3] The choice not to use a dual-clutch in oil bath was because it would lead to an increase in weight of over 70 kg (154 lb), negating the advantage of the ability of such transmissions to change gears faster.[3] As a result, the entire transmission of the Pagani Huayra weighs 96 kg (210 lb).[3]

Like many high-performance cars, the Huayra uses dry sump lubrication. This has several key benefits including guaranteeing oil flow even when the car is subjected to extreme lateral acceleration, preventing "oil surge" which allows the engine to operate more efficiently while the lack of an oil pan allows the engine mounted lower, lowering the car's center of gravity and improving handling.
A water / oil heat exchanger reduces engine warm-up times on cold days and helps maintain a stable temperature for refrigerant and lubricant.
To minimize the use of pipes and fittings (and the overall weight of the vehicle), the expansion tank is mounted directly on the engine. Intercooler fins act as an expansion tank circuit at low temperatures.
The titanium exhaust system was designed and built by MHG-Fahrzeugtechnik. Hydroformed joints were developed to reduce back pressure and ensure a free flow exhaust. Titanium reduces the weight of the exhaust system while the Inconel silencers improve reliability in the most exposed parts of the exhaust at high temperatures. The entire system weighs less than 10 kg (22 lb).
Chassis
The Huayra uses a carbotanium monocoque construction.[3] Advanced composite materials that are used on the Huayra were first used on the Zonda R.[3] The car features gull-wing doors.[3] The fuel tank is positioned behind the driver.[3]Aerodynamics
The Pagani Huayra is different to its predecessor in that it incorporates active aerodynamics.[3] It is capable of changing the height of the front from the ground and independently operating four flaps placed at the rear and front of the car.[3] The behavior of the flaps is managed by a dedicated control unit that is fed information from systems such as the ABS and ECU, which pass on information about the car's speed, yaw rate, lateral acceleration, steering angle and throttle position.[4] This is intended to achieve minimal drag coefficient or maximum downforce depending on the situation.[3] The system also prevents excess body roll in the corners by raising the "inside" flaps (i.e. the left ones in a left-handed corner and vice-versa), increasing the downforce on that side of the car. The rear flaps also act as an airbrake. Under hard braking, both the front suspension and the two rear flaps are raised to counteract weight transfer to the front wheels and keep the whole car very stable, for instance when entering a corner.[4] Air from the radiator is extracted through an arch in the bonnet at an angle that is designed not to affect the streamline around the body. The side air intakes behind the front wheels create a low pressure zone, resulting in downforce.Official debut
The Pagani Huayra was officially debuted online with many pictures in a press release on January 25, 2011.[3][5][6] The official world debut was at the Geneva Auto Salon 2011 in March.[7]EA secured the exclusive video game rights to the Pagani Huayra in 2011, available exclusively in Need for Speed titles in 2011, Shift 2: Unleashed and Need for Speed: The Run.[8] This license expired on the 31st of December 2011. The Pagani Huayra appears in the Jalopnik January DLC Car Pack for Forza Motorsport 4 along with other cars like the Ford Pinto, the Alfa Romeo Montreal and seven others.
