Kriya Gangiah, one of motorsport’s leading female voices in South Africa and host of this year’s Kyalami 9 Hour, understands that there are many who are still a little bit unfamiliar with the ins and outs of South Africa’s biggest international endurance race and shared seven basic facts about endurance racing ahead of this weekend’s big race:
- The Kyalami 9 Hour forms part of the Intercontinental GT Challenge Powered by Pirelli which features five rounds on five continents, with South Africa being the second stop on the calendar.
- Endurance races are time based. Drivers try to cover as much distance as possible in a fixed time. For the Kyalami 9 Hour, racers will, over the span of nine hours, try and complete as many laps as possible and the team that covers the longest distance will be crown the winners.
- Endurance races are more about teamwork. For the Kyalami 9 Hour there needs to be three drivers per team, with each driver having a maximum drive time of three hours and forty-five minutes across the nine hours. The drivers can swap at any time; however, a driver can only do a continuous “stint,” of three hours at a time. Each driver also needs to drive through the pitlane every 65mins.
- The race starts with a rolling start, this means that the cars will be led by the safety car in grid order around the track. After a certain number of laps the safety car will enter the pitlane and the green flag is waved, and the race will start as the cars cross over the start/finish line.
- Since the races are so long, pit stops are critical, and the amount of time spent refueling and changing tires can make or break a victory. This is really where the team strategy also comes into place.
- Each race consists of different classes. This means there will be drivers of different racing abilities racing in the Kyalami 9 Hour. Therefore, the pro drivers, pro-am drivers, silver and invitational drivers will be ranked together respectively.
- Balance of performance ensures that all the different manufacturers and engines compete on equal terms. Meaning a nibble Porche can go up against a mighty Mercedes. This makes driver skill more important.
