After the revision of the F1 championship (1961), the demise of the sportscar championship, replaced by the GT cars (1962), now was the time for another championship, this time the European Touring Car Challenge, which was for the new Group 2 "improved production cars". The cars could be improved within sharp limits, the number of carburettors could not be changed, 5-speed gearboxes and limited slip differentials could only be used if homologated.
In 1963, the challenge was organized within classes, with one overall champion:
Class 1: 0-600 cc | Class 4: 851-1000 cc | Class 7: 1601-2000 cc |
Class 2: 601-700 cc | Class 5: 1001-1300 cc | Class 8: 2001-2500 cc |
Class 3: 701-850 cc | Class 6: 1301-1600 cc | Class 9: over 2500 cc |
In 1964, the classes were organized as follows, still one champion:
Class 1: 0-700 cc | Class 4: 1001-1300 cc | Class 7: 2001-3000 cc |
Class 2: 701-850 cc | Class 5: 1301-1600 cc | Class 8: 3001-4000 cc |
Class 3: 851-1000 cc | Class 6: 1601-2000 cc | Class 9: over 4000 cc |
In 1965, the challenge was organized in 3 divisions, with separate champions:
Division 1: 0--850 cc, 851-1000 cc
Division 2: 1001-1300 cc, 1301-1600 cc, 1601-2000 cc
Division 3: over 2000 cc
Changed yet again in 1966, when division 3 started at 1601 cc.
