 Some of the European races featured Sports 2000 open bodied sports cars, but nothing larger than two litres engine capacity.No single driver started more than ten of the 16 races, with the Monza 1000 and the Riverside 5 Hour both occurring on the same day (and strangely both events counting towards the drivers title) no driver could attempt all 16.With over 1100 drivers competing it was one of the largest entries in the history of the sport.
