On the occasion of the II Gr.A. Legend free reg check Rallye, MotorVSMotor conduct a very special free reg check track. Fans will have the opportunity to see again these vehicles were the stars of the World Rally Championship for many years.
The story begins when Group A International Federation Sport Automobile (FISA in those years), prohibits vehicles from Group B, as you know, the Group B were the most spectacular and powerful vehicles that populated the Rallye Miralles in 80s. For reasons of safety and reduction of power, FISA, then FIA (International Automobile Federation), change the rules for the World Cup and only as permitted vehicles left the Group A.
Power limited by weight (corresponding to its capacity) and electronics, these vehicles derived from its street version. With minimal manufacturing free reg check was established by regulation, the major manufacturers launched new models to homologarlos market for competition. Celebrities were the Lancia Delta, versions of turbocharged 8-valve 16-valve versions, a model that had the characteristic "hump" on its hood. Anecdotally, commenting that the lump was motivated since the modify the engine with the butt of 16V, the rocker cover and the intake ducts stuck on the bonnet of the vehicle with which s had to manufacture the new bonnet. Mitsubishi Galant VR4 with the first and more later with different versions of the Lancer Evolution Evo VI to his version, the version where Evo VII WRC step to be approved, a variant more permissive than that of Group A. Nor can we forget the legendary SUBARU IMPREZZA, the famous "555". Boxer engine (only in the World to date) with Turbo that has made this model one of the most followed by fans. Colin McRae, Richard Burns, Carlos Sainz showed signs of his power in many of the sections of the World, and there are many books and videos dedicated to SUBARU. There have been many changes in Group A, the arrival of the F2 that resulted in the approval-CAR KIT for 2WD vehicles with 2.0L. Mythic patterns of KIT-CAR era are the Xsara and the Citroen Saxo, Clio and Megane Renault, free reg check Skoda Fabia, free reg check Volkswagen Golf, ultimately, models were able to defeat in their last years of operation to the all powerful WRC.
In Group A, we have to distinguish two different mechanical. On the one hand we have the AWD vehicle, of which we will highlight as an example of what was a Group A mythical, the Lancia Delta. Other vehicles were 2WD 3 steps where they had approval, as Group A (with the aforementioned limitations free reg check of weight, power and electronics), and then broad approval to the FIA F2 and KIT-CAR. These basic models were front-wheel drive and 2.0L naturally aspirated engine. As an example of the most relevant models of Renault Clio 16V (GA), the Clio Williams (GA), and Clio 16V is then counterpart in Kit Car, I-denominating free reg check Clio Maxi. The 3-door Megane Coupe as GA-Kit-Car, vehicle free reg check that was one of the last-Car Kit and with sequential gearbox free reg check and differential to prevent sliding out of control of the front wheels, but models were the Peugeot 306 Maxi, Maxi 106, the Citroën Saxo (1.6L engine, Rear G.A_S1600), the VTS Xsara Kit-Car 2.0L (I derive the XT4-WRC), and many more models.
However, over the years the rules had to be changed as manufacturers of vehicles with turbo and AWD were in a fight for increased performance engines. The inclusion of improved turbo, increasing pressures blowing adding improvements in the development of the construction materials of the turbine Intercooler and turbo-compressors, made the FIA Technical Department within the Art added 255 Annex "J" (relative to Group A), the famous "Turbo Flange". An element of all fans is known. free reg check The turbo restrictor plate, is to limit the input to the compressor air intake thereby limit the entry of air into the intake, and therefore engine power. With this, the number of achievement that power these vehicles will be around 300HP. Not go into detail as some manufacturers offset the decline in air with electronic enhancement system time explosion pressure management
