World Rally Car

World Rally Car is a term used to describe the racing automobiles built to the specification set by the FIA, motorsport's governing body, and used to compete in the outright class of the World Rally Championship (WRC). The specifications were introduced by the FIA in 1997. [cite web |url=http://www.suzukisport.com/wrc/e/whats_wrc/history/index.html |title=WRC History |publisher=Suzuki Sport]

Technical regulations mandate that World Rally Cars must be built upon a production car with a minimum of 2500 units, based on a pre-existing Group A model, to which a number of modifications may be added, including but not limited to increasing (or decreasing) engine capacity to 2.0 litres, adding a turbocharger, four wheel drive, sequential gearbox and aerodynamic parts, and the Anti-Lag System on turbocharged engines. The cars must also have a minimum weight of 1230kg.

, which have no road car with a turbocharged petrol engine or four wheel drive.To limit power, all forced inducted (turbo) cars are fitted with a 34 mm diameter air restrictor before the turbocharger inlet, this limits the air flow to about 10 cubic meters per minute. The restrictor therefore limits the power output to about 330-340 hp (officially 300 hp - which was correct about 10 years ago). Because of that, engine development is more focused on producing an engine with a very wide power curve rather than a high peak power output. This means that a power output in excess of 300 hp is available all the way from 3000 rpm to the red line of 7500 rpm with a peak of 330-340 hp at around 5500 rpm. At 2000 rpm, which is the idle speed in "stage" mode, the power output is slightly above 200 hp ["Subaru Rally Engine - Developing a World Rally Car power plant", page 23-30, Race Engine Technology, issue 005, 2004] . The cars are further modified for greater rigidity with rollcage and other chassis strengthening measures. Before each rally, the competing cars are fitted with suspension and tyres along with different differential settings to suit the conditions of the many stages, which may take place on asphalt roads, gravel and dirt roads of varying consistency, and even frozen snow-covered roads on some rallies held in relatively cold climates.
