'''Supercar''' is a term used for a high end [[sports car]], typically an exotic or rare one, whose performance is highly superior to that of its contemporaries. The proper application of the term is subjective and disputed, especially among enthusiasts. 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. The automotive press frequently calls new exotic cars "supercars". 
  
A '''supercar''' is a term used for a [[sports car]], typically an [[exotic car|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.  
+
==Origin of the term==
 +
The designation supercar was first applied to the [[Lamborghini Miura]] in a review by legendary British motor journalist [[L. J. K. Setright]].{{fact|date=April 2007}}

==Performance criteria==
 +
The term supercar usually refers to factory-built, [[Street legal |street-legal]] sports cars, rather than modified production cars that may have similar performance. Supercars are usually designed for road and amateur track use rather than racing alone, and because of this their standard equipment often does not include roll cages and other features required for [[race cars]].
  
* '''High Power, Low Weight''' — most supercars have a high [[power (physics)|power]] to [[weight]] ratio — that is, high engine power and low vehicle weight. This is done for the sake of  acceleration (see [[Newton's Second Law]]) and top speed. For example, the 2004 [[Porsche Carrera GT]] carries just five [[pound]]s per [[horsepower]] (3 kg/kW or 438 [[horsepower|hp]]/[[megagram|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.
+
Some common criteria for measuring whether a car should be considered a supercar include the following:
  
* '''High Acceleration''' — supercars, by the usual definition, have extremely quick acceleration compared to most vehicles, including ordinary sports cars. Some current expectations are as follow:
+
=== Design ===
** 0 to 60 mph (96.56 km/h): Under 4 seconds for virtually all supercars today.  The McLaren F1 has a 0 to 60 mph time of about 3.2 seconds.
+
Many supercars have a rear [[RMR layout|mid-engine]] (RMR), [[rear-wheel drive]] layout, which allows for better distribution of weight. This potentially increases overall traction, or grip, by moving weight away from the front and back ends of the car. The result is often handling, acceleration and braking capabilities that may have otherwise have been impossible to attain. Some supercar makers have started building [[all-wheel-drive]] supercars as new engines are producing more power than two wheels can take advantage of. For an example, see [[Bugatti Veyron]] or [[Lamborghini Murcielago]].
** 0 to 100 mph (160.9 km/h): Under 10 seconds is generally called for, with undisputed supercars being significantly faster. The [[Ferrari Enzo]], introduced in 2002, has a 0 to 100 mph time of about 6.5 seconds.
 
** Standing Quarter-Mile (402.3 meters): Under 13 seconds is arguably a requirement, as is a trap or terminal speed of at least 110 mph (177 km/h).  
 
*** The Ferrari Enzo completes the quarter mile from a stop in about 11.1 seconds at 133 mph (214 km/h).
 
*** The [[Koenigsegg CCR]], introduced in 2004, is officially claimed to run the quarter mile in "9 seconds, end speed 235 km/h (146 mph)" [[http://www.koenigsegg.com/thecars/index.asp?submenu=4]]
 
:It should be noted here, however, that the term supercar usually refers to particular models of factory-built, street-legal sports cars, which tend to be perceived as unmodified; heavily modified and potentially street-illegal vehicles can often accelerate faster than any production car, requiring well under 10 seconds in the quarter mile. Because supercars are usually designed for road use as opposed to drag racing or straight-line racing alone, their standard equipment often do not include roll cages and other mandatory requirements for fast cars on a [[dragstrip]].
 
  
* '''High Top Speed''' — Today, undisputed supercars can exceed at least 300 km/h or about 186 mph (even with a top speed of close to 300 km/h, the [[Ferrari 360]] is usually not considered a true supercar). Among many enthusiasts, a simple supercar requirement is the ability to break 200 mph (321.9 km/h).  The fastest models today have speeds exceeding 240mph (386 km/h).
+
=== Power-to-weight ratio ===
 +
Most supercars have high engine [[power (physics)|power]] and low vehicle [[mass]], for the sake of high [[acceleration]] (see [[Newton's Second Law]]) and good handling dynamics. For example, the 2004 [[Porsche Carrera GT]] masses just 3 [[kilogram]] per [[kilowatt]] (5 [[pound (mass)|lb]]/[[horsepower|hp]])—compare this to the similarly sized and shaped [[Porsche Boxster]] with nearly 7.1 kg/kW (11.7 lb/hp). The [[McLaren F1]], introduced in 1991 and one of the fastest supercars of the 20th century, produced 467.6 kW (627.1 hp) against a mass of 1140 kg (2513 lb), translating to 2.44 kg/kW (4.01 lb/hp).  Certain vehicles have a high power-to-weight ratio despite their heavy weight, due to a very powerful engine. For example, the Bugatti Veyron carries 2.61 kg/kW (4.30 lb/hp) despite weighing 1950 kg (4299 lb), including fuel <ref>[[Edmunds]] [http://www.edmunds.com/insideline/do/Features/articleId=108032 Bugatti Veyron]</ref>, due to its 746 kW (1001 hp) engine. The [[Koenigsegg CCR]] and [[Koenigsegg CCX]] have the highest power-to-weight ratio among production supercars: with 601 kW (806 hp) (on California grade 91 [[octane]] gasoline) and a weight of just 1,180 kg (2,601 lb) the Koenigsegg carries only 1.96 kg/kW (3.23 lb/hp).  According to the [[Shelby Super Cars]] website, the [[SSC Aero|Ultimate Aero TT]] holds the new production record, carrying a mere 1.42 kg/kW (2.33 lb/hp).
  
** On [[March 31]], [[1998]], the McLaren F1 (number XP5, a standard 1993 F1 road model) recorded an official top speed of 386.7 km/h (240.3 mph). The car was driven by Andy Wallace on the 9 km straight line of the Volkswagen Ehra-Lessien facility in [[Wolfsburg, Germany]]. This was the world record for production cars in the 20th century.[[http://www.mclarencars.com/content/sections/press/240.htm]][[http://www.e31.net/limiter.htm]]
+
=== Acceleration ===
** On [[February 28]], [[2005]], the Koenigsegg CCR with 806 hp (601 kW) achieved a top speed of 387.87 km/h (241.01 mph) on default settings. The car was driven on Italy's Nardo Prototipo proving ground, a circular track with a circumference of 12.5 km. This exceeded the McLaren's record.[[http://www.koenigsegg.com/record_pressrelease.asp]]
+
Supercars, by the usual definition, offer extremely high acceleration compared to most vehicles, including ordinary sports cars. Some current expectations are as follows:
** On [[May 20]], [[2005]], the [[Bugatti Veyron 16.4]] achieved a two-way average speed of 400 km/h (248.5 mph) at parent company Volkswagen's Ehra-Lessien test track. This exceeded the Koenigsegg's record.[[http://www.bugatti-cars.de/bugatti/]]
+
* 0 to 100&nbsp;km/h (62 mph): Under 4 seconds for virtually all supercars today. The [[Ultima GTR]] can go from 0 to 100&nbsp;km/h in 2.6 seconds and the [[Bugatti Veyron]] can do this in 2.5 seconds.<ref>[[Ultima Sports Ltd|Ultima]] [http://www.ultimasports.co.uk/records/part6.html Ultima GTR records]</ref>
 +
* 0 to 160&nbsp;km/h (100 mph): Under 6 seconds is generally recognized as the standard, with undisputed supercars being significantly faster.
 +
** The Ultima GTR, introduced in 2006, has recorded a 0 to 160&nbsp;km/h time of 5.3 seconds.
 +
** A Bugatti Veyron can achieve 0 to 160&nbsp;km/h in 5.5 seconds.<ref>[[Ultima Sports Ltd|Ultima]] [http://www.ultimasports.co.uk/records/part6.html Ultima GTR records]</ref>
 +
* 0 to 320&nbsp;km/h (200 mph): Under 30 seconds. [[McLaren F1]] 28 seconds, [[Saleen S7]] 23 seconds, Bugatti Veyron 22 seconds.
 +
* Standing quarter-mile (400 meter): Under 13 seconds is arguably a requirement, as is a trap or terminal speed of at least 175&nbsp;km/h (110 mph).
 +
** The [[Enzo Ferrari (car) | Ferrari Enzo]] completes the quarter mile from a stop in about 11.1 seconds at 214&nbsp;km/h (133 mph).
 +
** The Koenigsegg CCR, introduced in 2004, is officially claimed to run the quarter mile in "9 seconds, end speed 235&nbsp;km/h (146 mph)" <ref>[[Koenigsegg]] [http://www.koenigsegg.com/thecars/index.asp?submenu=4 Koenigsegg CCR]</ref>
 +
* Standing mile (1.6&nbsp;km): Trap (terminal) speed of at least 320&nbsp;km/h, for example the Saleen S7, Bugatti Veyron, [[Pagani Zonda]], Koenigsegg CCR, McLaren F1, [[Ferrari FXX]].
  
* '''Superb Handling''' &mdash; In contrast to a [[sports car]] which simply has a more 'sporty' or involving handling than a normal hatchback or saloon, a supercar is usually built for maximum cornering and road gripping ability in order to achieve superior racing times.
+
=== Top speed ===
 +
* On March 31, 1998, the [[McLaren F1 | McLaren F1 LM prototype]] set the speed record at 400km/h (250mph) at 7800 rpm. The production models are normally limited to  giving them a top speed around 231 mph. The prototype was driven by Andy Wallace on the 9&nbsp;km straight at Volkswagen's Ehra-Lessien test track in Wolfsburg, Germany.
 +
* On February 28, 2005, the Koenigsegg CCR with 601 kW (806hp) achieved a top speed of 387.87&nbsp;km/h (241.01 mph) on default settings. The car was driven on Italy's Nardo Prototipo proving ground, a circular track with a circumference of 12.5km. This exceeded the McLaren's record [http://www.koenigsegg.com/record_pressrelease.asp] The steering wheel was kept at 30 degrees, slowing the car; the car has not been tested on a straight track.
 +
* In October, 2005, [[Car and Driver|''Car and Driver'' magazine's]] editor [[Csaba Csere]] test drove the final production version of the Veyron for the November 2005 issue. This test, at Volkswagen's Ehra-Lessien test track, reached a top speed of 407&nbsp;km/h (253 mph). The Veyron can also go from 0 to 300 km/h (190 mph) in just under 19 seconds [http://www.bugatti-cars.de/bugatti/].
 +
 
 +
=== Handling ===
 +
A supercar is usually built for maximum cornering and road gripping ability in order to achieve superior cornering speeds. Lateral [[g-force|g]]-forces during the tightest turns can generally exceed 1 ''g''.
 +
 
 +
A popular [[benchmark]] is a [[lap time]] around the [[Nürburgring]] of under 8 minutes. There are also other tracks where supercars are being tested. Lap time tables from different racetracks are posted at [http://www.fastestlaps.com fastestlaps.com].

 +
In addition to performance, the following criteria are also cited in determining if a particular [[sports car]] or exotic car deserves the supercar moniker:
 +
* '''Brand''': Supercars are often very brand-centric (e.g. [[Ferrari]]) and a new brand wanting to join the list has to ''prove'' itself before its acceptance.
 +
* '''Styling''': Supercars often feature groundbreaking styling elements.  The [[Formula One]]-inspired Enzo Ferrari, for example, set a new styling direction for that company.
 +
* '''Rarity''': Virtually all cars classified as supercars undergo a very limited production run, typically no more than a few thousand in total. For example, the [[Corvette Z06]], though an extremely fast car, is mass produced and is very common, and thus is not sufficiently rare to be considered a supercar.
 +
* '''Focused design''': Supercars are not designed to be practical transportation devices, with functionality varying widely between different examples.  Many [[car body style]]s (including [[coupé|2+2 coupe]], [[station wagon]], and [[pickup truck]]) make inherent tradeoffs of performance potential for utility.  By this measure, extreme vehicles like the [[Dodge Ram SRT 10]] are not normally called supercars (in the case of Dodge Ram SRT-10, it is classified as a truck, not car, so the car-based description would not fit anyway). While one undisputed supercar, the [[McLaren F1]], featured seating for three (and had a number of useful storage spaces), performance was not sacrificed, but instead improved by the seating design: the driver's central position lowered the vehicle's [[polar moment of inertia]] and increased its turning ability.

* '''Technology''' &mdash; All supercars feature cutting edge contemporary racing car technology.  This has included the use of [[carbon fibre]] and [[ceramic]]s, [[ground effect]]s and [[wing]]s, and novel layouts like [[MR layout|mid-engine]].  The use of [[turbocharger]]s has fallen out of favor in many recent supercars, though the [[Bugatti Veyron]] will use four.  [[All wheel drive]] is also used in most modern supercars, reflecting the success of the [[Audi Quattro]] [[rally car]].
 
* '''Production''' &mdash; Most commentators would not include one-off [[concept car]]s or self-built [[kit car]]s under this category.  Although no objective metric has been agreed on, [[homologation]] often makes the case for a supercar.  Similarly, the term is never applied to a pure racing car &mdash; supercars must be legal for use on the street.  Although their makers often promise to produce dozens of examples, some supercars never reach these production targets.  For example, while 400 Enzos were built, just two [[Mosler|Mosler Photons]] have been sold.
 
* '''Spirit''' &mdash; An extremely difficult aspect to objectively discuss is the "spirit" or "soul" many supercar buyers search for.  This is often more a reflection of the manufacturer's reputation, especially on the race track, than the absolute qualities of the vehicle in question.  This factor is often cited in disqualifying cars like the [[Honda NSX|Honda/Acura NSX]] and [[Dodge Viper|Dodge/Chrysler Viper]] and including even the lesser V12-powered [[Ferrari]]s.

Template:Otheruses Supercar is a term used for a high end sports car, typically an exotic or rare one, whose performance is highly superior to that of its contemporaries. The proper application of the term is subjective and disputed, especially among enthusiasts. 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. The automotive press frequently calls new exotic cars "supercars".

Origin of the term

The designation supercar was first applied to the Lamborghini Miura in a review by legendary British motor journalist L. J. K. Setright.Template:Fact

Performance criteria

The term supercar usually refers to factory-built, street-legal sports cars, rather than modified production cars that may have similar performance. Supercars are usually designed for road and amateur track use rather than racing alone, and because of this their standard equipment often does not include roll cages and other features required for race cars.

Some common criteria for measuring whether a car should be considered a supercar include the following:

Design

Many supercars have a rear mid-engine (RMR), rear-wheel drive layout, which allows for better distribution of weight. This potentially increases overall traction, or grip, by moving weight away from the front and back ends of the car. The result is often handling, acceleration and braking capabilities that may have otherwise have been impossible to attain. Some supercar makers have started building all-wheel-drive supercars as new engines are producing more power than two wheels can take advantage of. For an example, see Bugatti Veyron or Lamborghini Murcielago.

Power-to-weight ratio

Most supercars have high engine power and low vehicle mass, for the sake of high acceleration (see Newton's Second Law) and good handling dynamics. For example, the 2004 Porsche Carrera GT masses just 3 kilogram per kilowatt (5 lb/hp)—compare this to the similarly sized and shaped Porsche Boxster with nearly 7.1 kg/kW (11.7 lb/hp). The McLaren F1, introduced in 1991 and one of the fastest supercars of the 20th century, produced 467.6 kW (627.1 hp) against a mass of 1140 kg (2513 lb), translating to 2.44 kg/kW (4.01 lb/hp). Certain vehicles have a high power-to-weight ratio despite their heavy weight, due to a very powerful engine. For example, the Bugatti Veyron carries 2.61 kg/kW (4.30 lb/hp) despite weighing 1950 kg (4299 lb), including fuel [1], due to its 746 kW (1001 hp) engine. The Koenigsegg CCR and Koenigsegg CCX have the highest power-to-weight ratio among production supercars: with 601 kW (806 hp) (on California grade 91 octane gasoline) and a weight of just 1,180 kg (2,601 lb) the Koenigsegg carries only 1.96 kg/kW (3.23 lb/hp). According to the Shelby Super Cars website, the Ultimate Aero TT holds the new production record, carrying a mere 1.42 kg/kW (2.33 lb/hp).

Acceleration

Supercars, by the usual definition, offer extremely high acceleration compared to most vehicles, including ordinary sports cars. Some current expectations are as follows:

  • 0 to 100 km/h (62 mph): Under 4 seconds for virtually all supercars today. The Ultima GTR can go from 0 to 100 km/h in 2.6 seconds and the Bugatti Veyron can do this in 2.5 seconds.[2]
  • 0 to 160 km/h (100 mph): Under 6 seconds is generally recognized as the standard, with undisputed supercars being significantly faster.
    • The Ultima GTR, introduced in 2006, has recorded a 0 to 160 km/h time of 5.3 seconds.
    • A Bugatti Veyron can achieve 0 to 160 km/h in 5.5 seconds.[3]
  • 0 to 320 km/h (200 mph): Under 30 seconds. McLaren F1 28 seconds, Saleen S7 23 seconds, Bugatti Veyron 22 seconds.
  • Standing quarter-mile (400 meter): Under 13 seconds is arguably a requirement, as is a trap or terminal speed of at least 175 km/h (110 mph).
    • The Ferrari Enzo completes the quarter mile from a stop in about 11.1 seconds at 214 km/h (133 mph).
    • The Koenigsegg CCR, introduced in 2004, is officially claimed to run the quarter mile in "9 seconds, end speed 235 km/h (146 mph)" [4]
  • Standing mile (1.6 km): Trap (terminal) speed of at least 320 km/h, for example the Saleen S7, Bugatti Veyron, Pagani Zonda, Koenigsegg CCR, McLaren F1, Ferrari FXX.

Top speed

  • On March 31, 1998, the McLaren F1 LM prototype set the speed record at 400km/h (250mph) at 7800 rpm. The production models are normally limited to giving them a top speed around 231 mph. The prototype was driven by Andy Wallace on the 9 km straight at Volkswagen's Ehra-Lessien test track in Wolfsburg, Germany.
  • On February 28, 2005, the Koenigsegg CCR with 601 kW (806hp) achieved a top speed of 387.87 km/h (241.01 mph) on default settings. The car was driven on Italy's Nardo Prototipo proving ground, a circular track with a circumference of 12.5km. This exceeded the McLaren's record [1] The steering wheel was kept at 30 degrees, slowing the car; the car has not been tested on a straight track.
  • In October, 2005, Car and Driver magazine's editor Csaba Csere test drove the final production version of the Veyron for the November 2005 issue. This test, at Volkswagen's Ehra-Lessien test track, reached a top speed of 407 km/h (253 mph). The Veyron can also go from 0 to 300 km/h (190 mph) in just under 19 seconds [2].

Handling

A supercar is usually built for maximum cornering and road gripping ability in order to achieve superior cornering speeds. Lateral g-forces during the tightest turns can generally exceed 1 g.

A popular benchmark is a lap time around the Nürburgring of under 8 minutes. There are also other tracks where supercars are being tested. Lap time tables from different racetracks are posted at fastestlaps.com.

Other criteria

In addition to performance, the following criteria are also cited in determining if a particular sports car or exotic car deserves the supercar moniker:

  • Brand: Supercars are often very brand-centric (e.g. Ferrari) and a new brand wanting to join the list has to prove itself before its acceptance.
  • Styling: Supercars often feature groundbreaking styling elements. The Formula One-inspired Enzo Ferrari, for example, set a new styling direction for that company.
  • Rarity: Virtually all cars classified as supercars undergo a very limited production run, typically no more than a few thousand in total. For example, the Corvette Z06, though an extremely fast car, is mass produced and is very common, and thus is not sufficiently rare to be considered a supercar.
  • Focused design: Supercars are not designed to be practical transportation devices, with functionality varying widely between different examples. Many car body styles (including 2+2 coupe, station wagon, and pickup truck) make inherent tradeoffs of performance potential for utility. By this measure, extreme vehicles like the Dodge Ram SRT 10 are not normally called supercars (in the case of Dodge Ram SRT-10, it is classified as a truck, not car, so the car-based description would not fit anyway). While one undisputed supercar, the McLaren F1, featured seating for three (and had a number of useful storage spaces), performance was not sacrificed, but instead improved by the seating design: the driver's central position lowered the vehicle's polar moment of inertia and increased its turning ability.
