A supercar is a term used for a sports car, typically an exotic or rare one, whose performance is highly superlative to its contemporary sports cars. The proper application of this term is subjective and disputed, especially among enthusiasts. In addition, the use of the term is dependent on the era; a vehicle that is considered to be a supercar at one time may not retain its superiority in the future. Nonetheless, the automotive press frequently calls new exotic cars "supercars". Also see the list of supercars to help understand the term subjectively. Tuning-masini.uv.ro

Performance criteria

·      High power-to-weight ratio — most supercars have high engine power and low vehicle weight, for the sake of high acceleration (see Newton's Second Law) and good handling dynamics. For example, the 2004 Porsche Carrera GT carries just five pounds per horsepower (3 kg/kW or 438 hp/Mg) — compare this to the Porsche Boxster which hauls nearly 12 pounds per horsepower (7.1 kg/kW or 193 bhp/Mg). The McLaren F1, introduced in 1991 and widely considered as one of the fastest supercars of the 20th century, produced 627.1 hp (467.6 kW) against a weight of 2513 pounds (1140 kg), translating to 550 hp per 1000 kilograms or 4 pounds per horsepower. Certain vehicles have a high power-to-weight ratio despite having a heavy weight, due to a powerful engine output. For example, the Bugatti Veyron carries 4.3 pounds per horsepower despite weighing 4299 pounds (1950 kg, including fuel), due to its 1001 PS (987 SAE hp/736kW) engine. Tuning-masini.uv.ro
