The pole-winning Honda NSX shared by Mario Farnbacher, Renger van der Zande and Bertrand Baguette had dominated up until that point.
It only faced serious pressure in the seventh hour when Audi Sport Team Car Collection’s Patric Niederhauser moved to within 1.5 seconds. At that stage the winner would also lift the Drivers’ crown, but Midrand’s famously unpredictable weather was about to deny both entries.
When the rain arrived, the cars scrambled into the pits for wet tyres but this was the moment that effectively ended Honda’s challenge: unlike its rivals, the team opted against also taking on fuel, leaving no choice but stop again for a full service before the finish.
The Honda eventually came home fourth.
Lechner Racing’s local Team Perfect Circle Porsche crewed by Andre Benzuidenhout, Saul Hack and Dylan Pereira completed the points-paying positions in 10th.
