Group C Challenge - Season one

Season two of the Retro Racing Manager's League was run using Group C machinery, contested over 12 rounds by 26 teams with two cars per outfit, with two drivers in each car.

After the success of the inaugural season using Grand Prix machinery, the second season featured Group C machinery from Le Mans fame, with each of the drivers having previously contested the famous 24 Hours of Le Mans without overall victory.

With 26 teams contesting the championship, two separate races were run per day with Class A featuring the top 13 teams in the standings while Class B was formed of the bottom 13. While each class features differing points systems, all teams across the board had a chance to take the championship with a promotion/relegation system in place from race to race, the top three teams from Class B going up while the bottom three teams from Class A go down.

Three titles were up for grabs in the Group C Challenge: Drivers' Champion, Teams' Champion and Celebrity Trophy Champion.

After a drama-filled inaugural season with many different victors, the Renown Mazdaspeed duo of Kamui Kobayashi and Keiichi Tsuchiya came away with the inaugural title of Drivers' Champions, with the team clinching the title at the season finale at Laguna Seca. Gabrielle Spangenberg took home the Celebrity Trophy title.

Class B
Both groups score one point for pole position and one point for fastest lap.

Cars must be classified to receive points.

In the event of tied points, the better result in the higher class will take priority. If both cars are in the same class, priority will be given to the car with more wins. If they are still tied, it then goes down to most second places, most third places and so on until a result is declared. In the highly unlikely event of a complete tie, the cars will share the position.
