Race Car Unveiled : Pagani Huayra The Pagani Huayra (pronounced: wai-rah) is an Italian mid-engined sports car produced by Pagani. Succeeding the companys previous offering, the Zonda, it costs £849,000 ($1,300,000). It is named after Wayra Tata, which means God of the winds in Quechua, the official language of the Inca Empire. The Huayra was named The Hypercar of the Year 2012 by Top Gear magazine and received a very positive review when tested by Richard Hammond on Top Gear. The Huayra is currently the fastest car to go around the Top Gear Test Track, setting a time of 1:13.8, beating the previous record of 1:15.1 set by the Ariel Atom V8 in January 2011. Engine : Mercedes-Benzs AMG division provides the engine of the Huayra. The 5,980 cc, twin-turbo, 60° AMG M158 V12, has been designed at the request of Pagani to reduce turbo lag and improve response, realized with smaller turbos, a different intercooler configuration 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 mounting the engine lower, lowering the cars center of gravity and improving handling. The fuel consumption of the Huayra is 10 mpg (23 l/100 km) in city and 14 mpg (17 l/100 km) in highway (EPA testing). A water / oil heat exchanger reduces engine warm-up times on cold days and helps maintain a stable temperature for refrigerants and lubricants. 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).
