pagani huayra
The Pagani Huayra (pronounced wai-rah) is an Italian mid-engined sports car produced by Pagani. The second car produced by Pagani, it succeeds the Pagani 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.
Like the Zonda, the Huayra uses a Mercedes-AMG 60° V-12 engine, now fitted with dual turbochargers. This engine, the M158, produces over 700horsepower and 1,000 N·m (740 lb·ft) of torque. Its top speed is 230 mph (370 km/h) 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 (370 km/h).
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 (210 lb).

Mercedes-Benz's AMG division provides the engine of the Huayra. The 5,980 cc, twin-turbo, 60° V12 is shared with the Mercedes-Benz SL65 AMG Black Series, 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.
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).
