Pagani Huayra Supercar
Checkout the Pagani Huaryra video here. Very nice car with a very high price starting at $2,500,000.
Amazingly the Huayra has a top speed of about 383 km/h (238 mph) and it has a 0-97 km/h (60 mph) acceleration time of 2.8 seconds. Using Pirelli tyres, the Pagani Huayra is capable of withstanding 1.66 g of lateral acceleration.
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. As a result, the 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.
The Huayra uses a 6.0 L (5,980 cc) twin-turbocharged M158 60° V12 engine developed by Mercedes-AMG specially for the Huayra, which has a power output of 730 PS at 5,800 rpm and 738 lbf⋅ft of torque at 2,250-4,500 rpm. The engine has been designed at the request of Pagani to reduce turbo lag and improve response, achieved with smaller turbo chargers, 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 car's center of gravity and improving handling. The fuel consumption of the Huayra is 10 mpg‑ in city and 14 mpg on the 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 minimise 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.
