2016 Red Rooster Sydney SuperSprint

Background

After running the car belonging to Dunlop Series driver Kurt Kostecki at the previous two events, Charlie Schwerkolt Racing completed the build of its new car two weeks prior to the event. The team's regular driver Lee Holdsworth, who had been injured at the Darwin event, completed laps in the car during a shakedown run at Winton Motor Raceway one week prior to the event, though the team's endurance co-driver, Karl Reindler, was announced as the driver for the race weekend.

Triple Eight Race Engineering and the Holden Racing Team also debuted new cars at the event, for Jamie Whincup and Garth Tander respectively. The two teams were part of an announcement from Holden in the lead up to the event, with the company announcing that the "Holden Racing Team" brand would be moved to Triple Eight for the 2017 season while Walkinshaw Racing, which had operated under the "Holden Racing Team" name in various guises since 1990, would have its factory support removed.

After Craig Baird stepped in to replace Aaren Russell at the previous event in Ipswich, Erebus Motorsport announced Dunlop Series driver Shae Davies as the full-time replacement for Russell. The car also sported a new livery with backing from Supa Centa Moore Park and Westfield Eastgardens. A number of other cars also carried new liveries: DJR Team Penske continued its sponsor rotation system with backing from MAN; Nissan Motorsport ran a Nissan Financial Services livery on Michael Caruso's car; and Lucas Dumbrell Motorsport featured a Repair Management Australia livery on both of its cars. Super Black Racing ran a tribute to its founder Tony Lentino, who passed away one month before the event. The other three cars run by Prodrive Racing Australia also displayed a tribute.

Whincup entered the event as the championship leader, 110 points clear of his teammate Shane Van Gisbergen, with Mark Winterbottom a further ten points behind in third.

Practice

Two one-hour practice sessions were held on Friday afternoon. Chaz Mostert set the fastest time in the first session, ahead of Tim Slade and Caruso. A number of endurance co-drivers completed laps: Matt Campbell for Nissan Motorsport; Cameron McConville for Lucas Dumbrell Motorsport; and Luke Youlden and Tony D'Alberto for DJR Team Penske. Light rain fell at the end of the session, preventing drivers from improving their times. The second session was topped by Scott McLaughlin with Van Gisbergen and Winterbottom completing the top three. Rick Kelly made contact with the wall at Turn 3 after the throttle became jammed open on his car. Despite sustaining only minor damage, he did not take part in the rest of the session as his team were unable to solve the throttle problem. The third and final practice session was held on Saturday afternoon and was 15 minutes in length. Winterbottom was fastest ahead of James Courtney and McLaughlin.

Qualifying – Race 18

Qualifying for Race 18 was a single 15-minute session held on Saturday afternoon. Reindler was forced to remain in the pit lane at the start of the session due to a problem with his car. Mostert took pole position by over two tenths of a second, setting a new qualifying lap record of 1:28.8272. Van Gisbergen and Whincup secured second and third ahead of Scott Pye, Courtney and Slade.

Race 18

Race 18 took place on Saturday afternoon, with the regulations requiring each car to make at least one pit stop to change all four tyres. Mostert maintained the lead at the start but ran slightly wide at Turn 3, allowing Van Gisbergen to take the lead at Turn 4. Whincup also passed Mostert at Turn 6 on the first lap. Pye attempted to pass Mostert on lap 4, but both drivers ran wide and Courtney was able to take advantage and move into third place. Todd Kelly was the first driver to complete his pit stop, doing so at the end of lap 7. One lap later, Pye retired from the race with a power steering problem. Van Gisbergen stopped on lap 14, followed by Courtney and Mostert on lap 16. Whincup stayed out until lap 17, with the aim being to have fresher tyres than his rivals at the end of the race.

After every driver had completed their pit stop, Van Gisbergen led from Whincup, McLaughlin, Craig Lowndes and Slade, with the tyre condition of each varying throughout the field. Courtney and Mostert used their younger tyres to move forwards and assume third and fourth position respectively by lap 26. Van Gisbergen and Whincup began battling for the lead in the closing stages, with the pair making slight contact at Turn 2 on lap 28. Smoke began issuing from the front-right corner of Whincup's car on the final lap; this was later revealed to be caused by rubber debris burning inside the brake disc. Van Gisbergen took victory by a quarter of a second over Whincup, with Courtney completing the podium ahead of Mostert, McLaughlin, Lowndes, Slade, Tander, Rick Kelly and Fabian Coulthard. Whincup's championship lead was reduced to 98 points, while Lowndes and Winterbottom became tied on points for third place after the latter finished eleventh.

Post-race

Nick Percat was penalised ten championship points, being charged with careless driving after making contact with Chris Pither during the race. DJR Team Penske changed the engine in Pye's car as it momentarily lost oil pressure when the power steering belt came off during the race.

Qualifying – Race 19

Qualifying for Race 19 was held on Sunday morning and consisted of a single 20-minute session. The top three qualifiers were the same as in Race 18, with Mostert taking his second pole position of the weekend ahead of Van Gisbergen and Whincup. Lowndes qualified fourth fastest ahead of his 600th championship race start, while Garry Rogers Motorsport locked out the third row with McLaughlin ahead of James Moffat. Courtney triggered the kerb sensor, a timing loop used to stop drivers exceeding the track limits, at Turn 5 on his final lap and his time was deleted as a result, leaving him to start twelfth.

Race 19

Race 19 was held on Sunday afternoon and the race regulations required each car to take on at least 120 litres of fuel during the race. The race was scheduled to be 52 laps in length, however this was reduced by one lap after a problem with the start lights led to an aborted start. Lowndes made a good start and moved into the lead around the outside of Mostert into the first corner, with Whincup in third ahead of Moffat, McLaughlin and Van Gisbergen. Winterbottom encountered a problem with his front-right tyre and was the first driver to complete a pit stop, doing so on lap 8. One lap later, Van Gisbergen was the first of the leaders to pit, followed by Lowndes and Whincup on lap 10. McLaughlin stopped on lap 12 while Mostert and Moffat stayed out until laps 15 and 16 respectively. After all drivers had completed their first pit stop, Lowndes led from Whincup, Van Gisbergen, Mostert and Moffat.

The second round of pit stops began on lap 28 when Todd Kelly stopped; he was followed by McLaughlin and Pye on lap 29. Lowndes and Whincup stopped on lap 30, with a slightly faster pit stop for Whincup seeing him emerge ahead of his teammate. Mostert and Van Gisbergen pitted on the next lap, leaving Moffat in the lead until he stopped on lap 35. After Pither completed his second pit stop, Whincup led from Lowndes, Mostert, Van Gisbergen and McLaughlin. On fresher tyres, Moffat was able to move past McLaughlin before attempting to pass Van Gisbergen on lap 47. However, he lost control and hit the back of Van Gisbergen's car, sending him into a spin. Despite giving the place back, Moffat was given a drive-through penalty and dropped to 18th place. Whincup won the race, securing his 100th championship race victory, ahead of Lowndes and Mostert. Coulthard was fourth ahead of Van Gisbergen and McLaughlin. Tander, Courtney, Rick Kelly and Caruso completed the top ten. The results saw Whincup extend his championship lead over Van Gisbergen to 137 points, while Lowndes moved clear of Winterbottom for this place.

Post-race

In recognition of his 100th race win, Whincup was presented with a golden helmet by James Warburton, the series' CEO, prior to the podium ceremony. He became the second driver to reach the mark after his teammate Lowndes, who had taken his 100th victory during the 2015 season. Whincup said it was "an honour to join Lowndesy on the ton" and thanked his team, Triple Eight Race Engineering, saying: "It’s been just over 10 years since my first win and I’ve had every one with the same crew, so a massive thank you to everyone at Triple Eight."

Moffat was frustrated to have received a drive-through penalty for the incident with Van Gisbergen, claiming a lack of consistency from the race stewards. Moffat said: "I readdressed straight away but then the penalty came through...I’m a bit confused by that and it seems like the reaction in pitlane is very similar."
