Porsche Carrera GT

The Porsche Carrera GT (Project Code 980) is a mid-engine sports car that was manufactured by German automobile manufacturer Porsche from 2004 to 2006. Sports Car International named the Carrera GT number one on its list of Top Sports Cars of the 2000s, and number eight on its Top Sports Cars of All Time list. For its advanced technology and development of its chassis, Popular Science magazine awarded it the "Best of What's New" award in 2003.

History
The development of the Carrera GT can be traced back to the 911 GT1 and LMP1-98 racing cars. Due in part to the FIA and ACO rule changes in 1998, both designs had ended. Porsche at the time had planned a new Le Mans prototype for the 1999 season.

The car was initially intended to use a turbocharged flat-six engine, but was later redesigned to use a new V10 engine, pushing the project back to planned completion in 2000. The V10 was a unit secretly built by Porsche for the Footwork Formula One team in 1992, but later shelved. The engine was resurrected for the Le Mans prototype.

Porsche did keep part of the project alive by using the 5.5 L V10 from the prototype in a concept car called the Carrera GT shown at the 2000 Paris Motor Show, mainly in an attempt to draw attention to their display. Surprising interest in the vehicle and an influx of revenue provided from the Cayenne helped Porsche decide to produce the car, and development started on a road-legal version that would be produced in small numbers at Porsche's new manufacturing facility in Leipzig. Porsche started a production run of the Carrera GT in 2004. The first Carrera GT went on sale in the United States on 31 January 2004.

Originally a production run of 1,500 cars was planned. However, Porsche announced in August 2005 that it would not continue production of the Carrera GT through to 2006, citing changing airbag regulations in the United States. By the end of production on 6 May 2006, more than 1,270 cars had been sold, with a total of 644 units sold in the United States and 31 units sold in Canada. In the United Kingdom, 49 units were sold.

Design
The Carrera GT is powered by a 5733 cc V10 engine rated at 450 kW, whereas the original concept car featured a 5.5-litre version rated at 416 kW. A road test in June 2004 by Car and Driver showed that the car can accelerate from 0–60 mph in 3.5 seconds, 0–100 mph in 6.8 seconds and 0–130 mph in 10.8 seconds. The official top speed was 330 kph.

Technology
Notable technology includes a pure carbon fibre monocoque and subframe produced by ATR Composites Group of Italy, dry sump lubrication and inboard suspension. At speeds above 70 mi/h, the electronically operated rear wing raises into the airstream to reduce lift. The radiator of the Carrera GT is about five times the size of that of a 911 Turbo of its time. The car's front and rear suspension system consists of pushrod actuated shock absorbers and dampers with anti-roll bars.

Zagato
In 2013, Zagato introduced the Porsche Carrera GTZ based on the Porsche Carrera GT. Commissioned by a Swiss Porsche collector and former racing driver, it has a modified carbon fiber body which is more aerodynamic. The car has the same technical specification as the Porsche Carrera GT. Six Carrera GTZs were built.
