Group S: The evolution of Group B that never accelerated

It was born to be the continuity of the drift monsters, although with a controlled performance.

In the mid-1980s, lovers of the World Rally they enjoyed the impressive vehicles of the B Group. They were small beasts with all-wheel drive, very light and with powerful turbo engines that reached the 500 horses. The main exponents were the Audi Quattro, the Lancia 037, the Peugeot 205 Turbo 16 and Lancia Delta S4, Among others.

This regulation imposed by the International Automobile Federation allowed brands to build vehicles exclusively to compete on the condition of manufacture only 200 units for the market. In addition, the new parts or evolutions were homologated with only 20 more cars being manufactured. In this way, cars were conceived from scratch at a low cost and without the need for mass production.

The walk of these thoroughbreds took the category to another level. The races were spectacular, but also dangerous. Between 1985 and 1986 there were a series of serious accidents - some fatal - that forced the FIA ​​to ban this type of vehicle.

Faced with this decision, the brands focused on the regulation of the Group A, which was originally born to replace the Group 2 and encourage the participation of private teams with vehicles limited in power, weight, technology and total cost.

So, right off the bat, Group S, which the FIA ​​had proposed as the logical evolution of Group B, also passed into oblivion. This new regulation allowed manufacturers to homologate their models by building only ten units, maintaining the same technical characteristics as the B (tubular chassis, four-wheel drive, central engine and fiber bodywork), although with weight and power limits, which would not be higher than 300 horses through restrictions on air intake and turbo pressure.

The decision to cancel the S Group came when several manufacturers had already started creating their own prototypes under these rules. Audi developed the Quattro RS002, Toyota the MR2 D222 and Lancia the ECV2, which is said to be able to accelerate from 0 to 200 km / h in ten seconds.

Group S obviously never skidded in World Rally Championship competitions. Some were the basis of other projects, others were dismantled and a few remain in museums or in the hands of collectors to remember something beautiful that could not be.
