Pagani Huayra
Encyclopedia
The Pagani Huayra is an Italian mid-engined
sports car
produced by Pagani
. Succeeding the company's previous offering, the Zonda
, it will cost £850,000 ($1,345,000) when it goes on sale in Spring 2012. It is named after Huayra-tata
, a South American wind god.
60° V-12 engine, now fitted with dual turbocharger
s. This engine, the M158, produces over 700 horsepower
and 1000 newton metre of torque. Its top speed is 230 mph (102.8 m/s) and it has a 0–100 km/h (0-62 mph) time of less than 3.5 seconds. Using Pirelli
tires, the Pagani Huayra is capable of withstanding 1.5g of lateral acceleration at speeds of up to 230 mph (102.8 m/s).
Unlike many modern supercars, the Pagani Huayra does not use a dual-clutch gearbox; instead it uses a seven-speed sequential gearbox and a dual-disc clutch. 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. As a result, the entire transmission of the Pagani Huayra weighs 96 kg (211.6 lb).
, but has been modified at the request of Pagani to reduce turbo lag and improve response, which resulted in smaller turbos, new intercoolers and re-programmed ECU settings.
The two radiators positioned laterally to the anterior face is intended to improve the efficiency of the intercoolers at the top of the cylinders. This cooling circuit at low temperature was designed to operate at temperatures exceeding 50 °C (122 °F).
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, reducing the car's center of gravity and improving handling.
A heat exchanger water / oil 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 M158 engine is certified to the most stringent environmental standards in Europe and America (EU5 and LEV 2).
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).

in that it incorporates active aerodynamics. 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. 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. This is intended to achieve minimal drag coefficient

depending on the situation. 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. 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.
