The WRC specifications were introduced by the FIA in 1997. Contents 1 Regulations 1.1 1997 -- 2010 1.2 2011 -- 2016 1.3 2017 2 Cars 3 References 4 External links Regulations 1997 -- 2010 A Subaru Impreza WRC2006 being prepared by Prodrive Between 1997 and 2010, the regulations mandated that World Rally Cars must have been built upon a production car with a minimum production run of 2500 units. A number of modifications could be made including increasing the engine displacement up to 2.0 L, forced induction ( including an anti-lag system ), addition of four wheel drive, fitment of a sequential gearbox, modified suspension layout and attachment points, aerodynamic body modifications, weight reduction to a minimum of 1230 kg and chassis strengthening for greater rigidity. Unlike the requirements for the preceding Group A cars, manufacturers were no longer required to build `` homologation specials '' in order to meet approval. The base model did not need to have all the characteristics of the WRC car, as evidenced from cars such the Peugeot 206, 307, Citroën Xsara and Škoda Fabia, which during this period had no road car variant with a turbocharged petrol engine or four wheel drive. One of the requirements was a minimum length of 4000 mm ; the standard Peugeot 206 had an overall length of 3835 mm and Peugeot had to produce at least 2500 units featuring extended bumpers to comply with the required dimensions. To limit power, all forced induction cars were fitted with a 34 mm diameter air restrictor before the turbocharger inlet, limiting the air flow to about 10 cubic meters per minute. The restriction was intended to limit power output to 300 hp although some WRC engines were believed to produce around 330 -- 340 hp. Engine development did not focus on peak power output but towards producing a very wide powerband ( or power curve ). Typically, power output in excess of 300 hp was available from 3000 rpm to the 7500 rpm maximum, with a peak of 330 -- 340 hp at around 5500 rpm. At 2000 rpm ( the engine idle speed in `` stage '' mode ) power output was slightly above 200 hp. By 2004, the best cars had ABS, clutch control, paddle shift, traction control, three active differentials, ride height control with GPS, electronic dampers and active suspension. In an attempt to cut costs, since 2006 new regulations required mechanical front and rear differentials, while the central differential remained active. Active suspension and water injections were also prohibited. Cars entered by a manufacturer had to be equipped with the same engine for two rallies ; further limitations were imposed on the changing of some parts, including suspension, steering, turbochargers and gearboxes. 2011 -- 2016 Starting in 2011, rules for WRC cars changed to be more restrictive. Now regulations were derived from Super 2000 cars with a different aerodynamic kit. The cars were smaller models ( there was no longer a minimum 4m length ), with a 1600 cm direct injection turbo - charged engine with a 33 mm diameter air restrictor and a maximum pressure of 2.5 bar absolute ( this will limit torque to about 400 N.m or less ). Exotic materials ( titanium, magnesium, ceramics and composite ) were forbidden except when present in the base model. Carbon fibre and aramid fibre were very restricted ( `` only one layer of fabric is used and is affixed to the visible face of the part '' ), except for bodywork 's side protections where multiple layers of aramid fibre are allowed. The gear changes must be made with a mechanical system, so the paddle shifters were not allowed. However the system was re-allowed in 2015. There was no center differential ( earlier it used to be 3 differentials, with a center / 3rd differential included ), but the new regulation allows only front and rear axle differential ( eliminating the center differential to reduce cost ), and they must be mechanical, without electronic control or hydraulic or viscous systems ( from 2006 to 2010 the center differential and previously all three could be active ). Minimum weight is 1200 kg empty and 1350 kg with driver and co-driver ( in both cases with only one spare wheel ). 2017 The 1.6 L turbo - charged engine was retained in the 2017 World Rally Car regulations, but the turbo restrictor diameter was increased from 33 mm to 36 mm, increasing the engine 's power output from 310 bhp ( 223.7 kW ) to 380 bhp ( 283.4 kW ). Minimum vehicle weight was decreased by 25 kg. Manufacturers are also given more freedom to maximise aerodynamic performance, large brake cooling ducts in fairings forming enlarged wheel arches, and are allowed to use electronically - controlled active centre differentials, while the front and rear differentials remain mechanical. While 2011 specification World Rally Cars will be allowed to compete in 2017, the new World Rally Cars are allowed for use by manufacturers ' teams only.
