Robin Frijns, Stuart Leonard, and Dries Vanthoor won the 2018 Bathurst 12 Hour, after the race was declared early due to a massive final-stint crash.
Frijns led the field during a final hour economy test, building to a tense showdown in the Intercontinental GT Challenge opener with Jamie Whincup and Earl Bamber.
But a huge crash between Audi driver Ash Walsh and Mercedes driver John Martin with 20 minutes to go led to the race ultimately being suspended, the clock ticking down to zero as crews were parked on the front straight waiting for a restart.
As a result the #37 WRT Audi was declared the winner, ahead of the #75 Mercedes (Whincup/Tristan Vautier/Kenny Habul/Raffaele Marciello) and the #991 Porsche (Bamber/Kevin Estre/Laurens Vanthoor).
The first of the key moments of the final quarter of the race came just half an hour in, when the scrap for third turned into a melee at Forrest's Elbow.
It started when Chaz Mostert (#43 Schnitzer BMW), who had dominated the early part of the race from pole before team-mate Marco Wittmann earned a penalty for passing backmarkers before a restart, got into the back of Estre in the #991 Craft-Bamboo Porsche on the way out of the Dipper.
Then, as the pair tried to squeeze past a class B Porsche on the run onto Conrod, more contact led to Mostert wiping out Steven Kane in the #17 Bentley, which was a few metres down the road.
Estre managed to sneak through largely unscathed, diving straight into the pits to hand over to Earl Bamber. Kane and Mostert also got back to the garage, but were left well and truly out of contention for victory, while the #42 class B Porsche was left hanging out of the wall.
With the crashed Porsche cleaned up, the race restarted with two hours and 20 minutes to go. David Fumanelli led the field in the #55 Strakka Mercedes, but ran wide and immediately handed it over to Markus Winkelhock in the #74 Audi.
In keeping with the theme of the day, the green running was shortlived. The 14th safety car period quickly followed when the #777 Buik Lamborghini lost a wheel, Fumanelli pitting and handing second over to Frijns.

But just as that was shaping up to be the main battle pack, the game changed again. This time it was heartbreak for the leading Audi, Winkelhock left stranded on The Mountain due to a drivetrain issue with a little over 90 minutes to go.
The sister Jamec Pem Audi had been in the thick of the lead fight too, before dropping out when Kelvin van der Linde crashed.
The safety car for Winkelhock meant Frijns, Whincup, and Bamber headed to pits with a stint and a bit to go.
Frederic Makowiecki took over the lead when the race restarted with 80 minutes left to run, but needed to pit again while the likes of Frijns, Whincup, and Bamber were close to being able to run to the end.
With 45 minutes left Makowiecki made that stop, leaving Frijns out front from Whincup and Bamber.
The final twist in the tale came with 20 minutes to go. Having clashed with a backmarker, Walsh was left stranded across the track on the run to McPhillamy. He was then hit at full-speed by Martin who arrived unsighted, causing the 16th safety car period of the day.
The caution eased fuel concerns, but even cruising around behind safety car the leading crews were worried. The intrigue deepened with 11 minutes to go when the red flag was flown, drivers advised to pull up on the grid and teams told not to work on the cars.
While the cars stopped, the clock kept ticking. In the end it ran out before the race could be restarted.
Behind the top three, the #540 Black Swan Racing Porsche (Marc Lieb/Luca Stolz/Jeroen Bleekemolen/Tim Pappas) won the Pro-Am class with fourth outright.
Like the #12 Competition Porsche behind it, an outright victory could have been on the table had the race run its course.
Romain Dumas capped off a remarkable day for Porsche with sixth in the #911 entry.
