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
