19-774: The Suzuki SX4 WRC is a World Rally Car built for the Suzuki World Rally Team by Suzuki in the World Rally Championship . It is based upon the Suzuki SX4 road car, and was debuted at the 2007 Tour de Corse . At the 2007 Geneva Motor Show , Suzuki announced it would enter the FIA World Rally Championship , with the factory backed Suzuki World Rally Team in the World Rally Car category in 2007, using

38-532: A different aerodynamic kit. The cars could be smaller models (there was no longer a minimum 4 m length) and include a custom-build or production 1600 cm direct injection turbo-charged global race engine with a 33 mm (1.3 in) diameter air restrictor and a maximum boost pressure of 2.5 bar (36 psi) absolute. This limited torque to about 400 N⋅m (300 lb⋅ft) or less ). Exotic materials ( titanium , magnesium , ceramics and composite ) were forbidden except when present in

57-505: 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. The maximum width was set at 1770 mm while front and rear tracks shouldn't exceed 1550 mm. 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

76-462: Is to further cut costs by introducing competition into gearbox supply. These new rules allowed Ford to build from scratch their S2000 Fiesta vehicles in Australia, in as little as 14 weeks, starting out with a Super 1600 chassis and rollcage. Until 2011, FIA specifications for Super 2000 cars were as follows: In 2011 the specifications were revised, allowing 1600 cc turbocharged engines, and

95-831: The SX4 WRC with AWD and the J20 engine producing 320 hp (239 kW; 324 PS) and 590 N⋅m (440 lb⋅ft) of torque. However, due to WRC calendar changes Suzuki officially debuted in 2008 , using the season of 2007 as further development time for the SX4. The SX4 competed on a test basis in two 2007 WRC events: the Rallye de France in October 2007 (finishing 31st overall) and the Rally GB in November 2007 (finishing 27th overall). In

114-560: The Super 2000 classification is to allow more manufacturers and privateers to race by reducing the cost of a competitive car. In order to cut costs and shorten development time, the Super 2000 rally cars originally used a common control gearbox and drivetrain made by the French company, Sadev . The FIA has since announced that Xtrac and Ricardo Consulting Engineers will be allowed to also manufacture S2000 gearboxes to FIA specification. This

133-477: The Super 2000 specification, and be powered by a 1600 cc turbo engine instead of the 2000 cc used previously. The WRC car would thus be based on the current 2011 model Super 2000 cars fitted with a supplementary kit for rallying. The kit must be able to be fitted or removed within a defined time limit. Notes: The following cars were built under the TC1 (2014–2017) regulations: The following cars were built under

152-403: 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 were allowed. The gear changes must be made with a mechanical linkage system, so paddle-shifters were outlawed. However the system was re-allowed in 2015 . There

171-430: The center differential and previously all three could be active ). The minimum weight was 1200 kg empty and 1350 kg (1360 kg from 2013) with driver and co-driver (in both cases when measured with only one spare wheel ). The 1.6 L turbo-charged global race engine was retained in the 2017 World Rally Car regulations, but the turbo restrictor diameter was increased from 33 mm to 36 mm, increasing

190-446: 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. Starting in 2011, rules for WRC cars changed to be more restrictive. New regulations were derived from Super 2000 cars with

209-536: 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. To limit power, all forced induction cars were fitted with a 34 mm diameter air restrictor before the turbocharger inlet, limiting the airflow to about 10 cubic meters per minute. The restriction

228-446: The engine's power output from 230 to 280 kW (310 to 380 hp). The minimum empty vehicle weight was decreased by 10 kg but the combined vehicle, crew and spare wheel weight remained at 1360 kg. Manufacturers were given more freedom to maximise aerodynamic performance, including large brake cooling ducts in fairings forming enlarged wheel arches. Electronically controlled active centre differentials were permitted, while

247-623: The event in Suzukis for six years running, the last three of which were in the SX4 HCS, and set the track record time of 9:51.278. World Rally Car 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 2.0L, forced induction (including an anti-lag system ), addition of four wheel drive , fitment of

266-489: The first event of 2008, the Rallye Monte Carlo , Suzuki driver Per-Gunnar Andersson finished eighth. A race car called 'Suzuki SX4 Hill Climb Special' was used at the 2011 Pikes Peak International Hill Climb . It was a specially adapted Suzuki SX4, with a twin turbocharged 3.1 litre V6 engine producing 910 hp (679 kW; 923 PS) and 890 N⋅m (660 lb⋅ft) of torque. Driver Nobuhiro Tajima won

285-759: The front and rear differentials remain mechanical. While 2011 specification World Rally Cars were allowed to compete in 2017, the new World Rally Cars were allowed for use by manufacturers' teams only. Super 2000 Super 2000 is an FIA powertrain specification used in the World Rally Championship , the British Touring Car Championship , the World Touring Car Championship , and other touring car championships. The engines were originally 2 L naturally aspirated, and later 1.6 L turbocharged units were allowed producing approximately 280 bhp. The goal of

304-495: The use of 2000 cc normally-aspirated engines rapidly stopped as a result. These 1600 cc turbo engines fully replaced the 2 litre engines. For the 2014 WTCC season, the TC1 regulations were introduced for touring cars. For the engine this included a larger air intake restrictor allowing power outputs of 380 bhp and more. New regulations for the FIA World Rally Car were introduced in 2011. WRC cars would use

323-529: Was intended to limit power output to 220 kW (300 hp) although some WRC engines were believed to produce around 250–250 kW (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 220 kW (300 hp) was available from 3000 rpm to the 7500 rpm maximum, with a peak of 250–250 kW (330–340 hp) at around 5500 rpm. At 2000 rpm (the engine idle speed in "stage" mode) power output

342-484: Was no center differential (earlier it used to be 3 differentials, with a center/3rd differential included), but the new regulation allows the only front and rear axle differential and a mechanical clutch to disconnect the rear axle during handbrake use (to reduce cost and make the cars' driving style more exciting again for both spectators and TV broadcasts). These two differentials must be mechanical, without electronic control or hydraulic or viscous systems (from 2006 to 2010

361-460: Was slightly above 150 kW (200 hp). By 2004, the best cars had ABS , electronic clutch control, paddle-shift , traction control , three active differentials , ride height control with GPS, electronic dampers and active suspension . For 2005 the maximum width of the WRC cars was increased from 1770 mm to 1800 mm. In an attempt to cut costs, since 2006 new regulations required mechanical front and rear differentials, while
