While most of the attention at the end of the Bathurst 12 Hour was focused on Matt Campbell in his Porsche 911 GT3-R and his relentless march to a well-earned victory, the last four laps also saw another battle taking place.

Supercars driver Shane Van Gisbergen and Raffaele Marciello were locked in a cat-and-mouse chase for the third step on the podium.

With only those four laps to go, SVG was clearly trying hard to make a move on Marciello, but the 24-year-old Italian had other ideas.

For four laps, Van Gisbergen pushes Marciello constantly but finds little opportunity to pass as the former Ferrari Academy driver makes his car as wide as possible.

By the end of the few laps – and the end of the half-day race – there were only a couple of tenths in it. Marciello finished with 12:02.00 between he and his co-drivers, while SVG (joined by Jamie Whincup and Craig Lowndes) finished with 12:02.20 on the clock.

Afterwards, Van Gisbergen was seen collapsed beside his car, which Speedcafe later reported was simply due to a cramp.

“To get the performance I had to use two feet pushing as hard as I could as something was just not been right with the brakes all weekend,” he told Speedcafe.

“I just started cramping. Just the brake pressure, just the cramp in my legs. I’ve never, ever driven a car where the brakes are that bad. So It was tough.

“I just tried to stretch my legs out. I was cooking as well, just my legs.”

In front of Marciello taking second place was Jake Dennis, driving the Aston Martin Vantage V12 GT3.
