1970 saw the introduction of new rules that created the new Group 2 category. This was the first golden era for touring car racing with the Ford Capris and Escorts racing against the likes of BMW and Alfa Romeo. The racing was exciting with side-by-side wheel lifting action at every turn and championships being won by the slightest of margins.
The rules required 1000 cars to be produced but these could be modified quite freely. At the beginning of the championship, there were three divisions: 0-1000cc, 1001-1600cc, and over 1600cc. The smallest division was dropped in 1973 under heavy pressure from BMW and Ford.
Ford choose to enter a massive works team in 1970 that struggled at first but took a stranglehold on the series from 1971 until mid-1972. This is when their famous team director Jochen Neerpasch moved to BMW where his clever homologation tricks brought BMW to the front and they never looked back. Alfa Romeo was in the fight the whole time with both the 1300 GTA Junior and the 2000 GTAm. Unfortunately, their team direction and management were not as strong as Ford’s or BMW’s.
Unfortunately, the fuel crisis of 1973 all but ended the Championship as cars were not allowed to run on Sundays in Germany – including race cars. As a result, the works entries became sparse and the championship was left to privateers with very expensive cars.
The Austin Slot Car Club will be recreating this great series but doing it on the club’s rally track where there is only one car on the track at a time. Even though there won’t be any fender rubbing in the turns there is sure to be some great racing and drama for this new series.
