    Post Stay of execution for WRC Cars

    Following a meeting of the World Motor Sport Council, the FIA has announced its future plans for regulations in the World Rally Championship.

    New regulations for the next generation of WRC cars will become effective from the 2011 season and will see cars based on the current Super 2000 and Group N machines.

    Cars will be fitted with a supplementary kit including a turbo and rear-wing additions, although the kit must be able to be fitted to or removed from the car within a defined time limit which has yet to be determined.

    The new WRC car will be permitted to compete in the series from the 2009 season and will be able to score points in the WRC from 2010, where the current WRC machines will also be allowed to compete.

    That comes after the FIA announced that the current regulations will be extended into 2010, although cars will be subject to technical controls.

    In other news following the WMSC meeting, the FIA has confirmed that the restriction on parts will be eased for new manufacturers in their first year of entering the championship with immediate effect.

    A new manufacturer will be able ask the FIA for a waiver to use two additional engines without penalty, and a change of parts, as described in the WRC sporting regulations.

    from the FIA website: FIA press release 32608
    WORLD RALLY CHAMPIONSHIP

    With immediate effect, the restriction on parts will be eased for new manufacturers in their first year of entering the Championship. A new manufacturer may ask the FIA for a waiver to use two additional engines without penalty, and a change of parts, as described in the Sporting Regulations.

    The new technical regulations for the future World Rally Car will become effective from 2011. The WRC Car will be based on the current Super 2000 and Group N cars, fitted with a supplementary kit, which includes turbo and rear-wing additions. The kit must be able to be fitted or removed within a defined time limit, to be determined.

    The current World Rally Car regulations will be extended to include the 2010 World Rally Championship, subject to technical controls. The new World Rally Car will be permitted to compete from 2009 and score points in the Championship from 2010.

    From 1 January 2009, winning co-drivers in the FIA Junior and Production Car World Rally Championships will be awarded a world title.

    --------------------------
    so from what i understand the 2011 WRC Cars will be based of Super2000 and GroupN Cars.

    So for the uneducated what are the main differences from the current group N cars and Full WRC spec cars?

    Group N:
    In Rallying, the Production World Rally Championship(PWRC) is run under Group N rules. The cars used were modified road cars, often based on turbocharged, four wheel drive versions of standard small cars such as the Subaru Impreza WRX and the Mitsubishi Lancer Evolution, although a wide range of vehicles is homologated by the FIA for use in Group N.
    The range of modifications allowed is quite narrow - few mechanical engine modifications are allowed (save for lightening within set limits and baffled sumps) although the choice of ECU is free, and this can liberate some extra power itself, and most of the modifications allowed are to promote longevity rather than increased performance, although the boundaries of these two areas are blurring.
    Originally, Group N meant that all the interior trim had to be present (including the rear seat), whereas this has now changed to allow removal of the trim aside from the dashboard and replacement of the door trim. The springs and dampers are free, as are the internals of the gearbox, providing that the homologated gear ratios and gearchange pattern are respected. This allows the use of 'dog' engagement gearboxes, providing quicker gearchanges and longer gearbox life. There is provision for strengthening of the suspension components and bodyshell, providing this doesn't alter the operating principle.
    The FIA and many national motorsport associations are moving towards making rallying championships based in Group N, in an attempt to reduce costs, reinforce the link between motorsport and the car that the member of the public drives, and to reduce the environmental impact of motorsport.
    Group N

    ---------------------------------------------------------------------------
    WRC(world rally car) Car:
    World Rally Car is a term used to describe the racing automobiles built to the specification set by the FIA and used to compete in the outright class of the World Rally Championship (WRC).
    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, active differential, sequential gearbox and aerodynamic parts, and the Anti-Lag System on turbocharged engines. The cars must also have a minimum weight of 1230kg.

    However, unlike Group A, manufacturers are no longer required to build "Homologation Specials" in order to meet approval. The base model need not have the characteristics of the WRC, as evidenced from cars such the Peugeot 206 and 307, Citro&#235;n Xsara, or the Skoda Fabia, 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 ouput 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 [1]. 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.

    Super 2000, also known as S2000, is an FIA specification and classification for production based race cars. The specification is split to cover both rally and touring car racing. Super 2000 rally cars are also permitted to compete in Production World Rally Championship events alongside Group N cars.[1] The goal of the Super 2000 classification is to allow more manufacturers and privateers to race by reducing the cost of a competitive car. The World Rally Championship currently has three manufacturers currently fielding teams, while private teams rely on older cars from current manufacturers or from "works" teams that have left the WRC, such as Škoda or Mitsubishi.
    In order to cut costs & shorten development time, the Super 2000 rally cars originally used a common control gearbox & drivetrain made by a French company, Sadev. The FIA has since announced that Xtrac[2] and Ricardo Consulting Engineers will be allowed to also manufacture S2000 gearboxes to FIA spefication. This is to further cut costs by introducing competition into gearbox supply.

    Comparing to the previous 2007 model, a shortened overall length(-50mm) and rear overhang(-120mm), widen tracks(Front +40mm, Rear +45mm), change in weight distribution to the front and rear of the car, plus optimization of the centre of gravity and roll centre contribute to the improvement of the handling of the vehicle. An increased competitive edge is the aim for this new model.

    I'm not so sure its better more of just different. The TC thing wasn't that big of a deal but the engine freeze was stupid and wait till they really start working on their newfound "green" agenda.

    yea well the green thing could kill it, but capping the HP and taking away the nannies IMO are good changes.


    the WRC cars becoming like GroupN cars will be great for consumers because they will be forced to build stuff into their production cars to get them into the rally cars.

    well wait just a second... the KERS system they are introducing into F1 should be pretty awesome in 2009, itll be like a push to pass system. this is part of F1's "green" program as well. i dont know how many of yall keep up with formula SAE, but SAE just introduced Formula Hybrid, a new class that uses hybrid or all electric power they are impressive, faster than some of the fastest Forumla SAE cars. A&M is building one this year. i think this whole green thing is being blown out of proportion, a freind of mine and i were talking and we thought F1 would be really awesome if there were some ground rules about safety and it must be petrol powered, but for the most part the rules were free-(active aero, turbos, unresctied weights, hybrid technologies, KERS,.. anything goes) the only catch is that at the start of the race you get a predertimned amount of fuel say- 20 gallons. and if you run out DQ, so the point is to develop technologies that could end up on your car someday, not to develop something that would never ever relate to your car....

    Well, not sure if it's a good or bad thing but...It will be much easier for people to mock up their own wrc replicas and drive them around. No widebody needed, just slap on some vinyl, a goofy wing and a roof scoop and bam, you're petter solberg.
