![]() After completion, FISA officials would then be invited to physically count the cars. Thus, most cars were often roughly finished, somewhat unreliable, and unpractical for daily use. Many of the homologation road cars were designed by the rally teams themselves and not by the manufacturer. HOMOLOGATION 200 Citroën Visa Trophée lined up at the Heuliez plant for homologationįor a Group B car to be accepted in sanctioned competition, manufacturers had to produce a minimum of 200 identical units within a 12 month period. You can view the complete period FIA “Appendix J” by choosing either of these options (Group B regulations were identical from 1982 to 1985, limitations to aerodynamic overhangs and the prohibition of aluminium roll cages were implemented for 1986) Not doing this correctly would handicap the car in one way or the other. The rest of the chassis and suspension could therefore be set up to run the properly sized tires within the class limits. The best way to maximise a Group B car was to make it as light as possible so that its weight closely matched its engine displacement class minimum requirement (taking into account the 1.4 forced induction multiplier, if applicable). Maximal tire width combinations for one side of the vehicle – staggered setups allowed Īs such, when building the cars, Group B engineers had to approximate the race weight of their designs in harmony with the engine choice to properly set the cars up for the specific weight and tire classes. The adjusted figure was used to determine minimum weight requirements and maximal tire width combinations for the particular model. Meaning that, in example, a twin-charged Lancia Delta S4, although it had a 1759 cc engine, would get a final cc rating of 2463 cc. The FISA (FIA) mandated that forced induction engines (with a turbocharger, supercharger or both) would get a multiplication factor of 1.4 to calculate their “final” engine displacement figure. Group B cars were divided into 4 different classes pertaining to their “final / adjusted” engine displacement This rule can be credited with the forceful Group B homologation of low-powered cars with high production numbers such as the Peugeot 504 Pickup and other supermini models that had very small cabins. It is notable to mention that Group A & N had a minimum interior space requirement for homologation and if that figure wasn’t met the car was automatically transferred into Group B. All of the rest was mostly free minus specific basic safety requirements.Run a maximum tire width combination calculated via engine displacement (x 1.4 for forced induction – see list below).Respect a minimum race weight calculated via engine displacement (x 1.4 for forced induction – see list below).The cabin had to fit two seats side by side and could not be open roofed.PDF File - Time Speed Distance - Road Rally Roadbook Įxcel download file is completely editable.

TSD (Time/Speed/Distance) rallying is a safe, enjoyable but exacting motor sport that fully puts to the test your car’s reliability and responsiveness, a driver’s ability and a navigator’s accuracy in interpreting specific route instructions.
