Browning led from start to finish in the F3 feature race in Bahrain after polesitter Gabriel Bortoleto bogged down and dropped to the rear of the pack.
While the Hitech driver appeared in complete control of the race, however, there were concerns that he may be forced to retire after second-placed Christian Mansell reported seeing smoke coming from Browning’s car.
The onboard cameras and the audio of the engine sparked suggestions that one of the six engine cylinders could have failed.
Speaking to Autosport Browning explained that despite initially fearing the worst, he and his team were quickly able to diagnose the issue.
“I thought – I knew – the exhaust had just blown because it went really loud,” said the Briton. “So basically, the exhaust on the F3 car, they have this wrap around them and I think one of the springs came loose on the wrap.
“Therefore, when the wrap comes loose, it gets really hot on one part and it blows a hole in it.
“I was never in any danger of it failing, but it was a bit scary at one point when I heard a bang. I wasn’t sure if it was the engine gone or just the exhaust.
“Luckily, the power was still good and we were able to keep on going.”
