The 2016 International V8 Supercars Championship (often simplified to the 2016 V8 Supercars Championship and known from 1 July as the 2016 Virgin Australia Supercars Championship) was an FIA-sanctioned international motor racing series for Supercars. It was the eighteenth running of the Supercars Championship and the twentieth series in which Supercars have contested the premier Australian touring car title.
Mark Winterbottom started the season as the defending drivers' champion, while Triple Eight Race Engineering were the defending teams' champions.
Shane van Gisbergen, driving for Triple Eight Race Engineering, secured his first championship title with one race remaining, winning eight races during the season. Triple Eight Race Engineering won the Teams' Championship for the seventh consecutive season. Van Gisbergen, along with Alexandre Prémat, also won the Pirtek Enduro Cup.
Twenty-six cars contested the 2016 season. Holden, Nissan and Volvo were all represented by factory-backed teams. Ford, having scaled back its involvement in 2015, were providing no financial or technical assistance, but were still represented by Prodrive Racing Australia and DJR Team Penske.
The following teams and drivers competed in the 2016 championship.
Charlie Schwerkolt Racing terminated its customer arrangement with the Holden Racing Team, to field an in-house entry under the new Team 18 name.
DJR Team Penske expanded to run two cars, having run a single car in 2015. The team took back the Racing Entitlement Contract (REC) it had leased to Super Black Racing in 2015.
Erebus Motorsport switched from running Mercedes-Benz E63 AMGs to Holden Commodore VFs.
Triple Eight Race Engineering expanded to field three cars, purchasing a REC last used in 2014 by James Rosenberg Racing.
Walkinshaw Racing ceased at the end of 2015, with its REC sold to Super Black Racing.
Chaz Mostert moved from Prodrive Racing Australia to Rod Nash Racing, replacing David Reynolds. The team cited commercial reasons and not having to share a pit boom with Mark Winterbottom as the reason for the change. Reynolds moved to Erebus Motorsport, replacing Will Davison.
2015 V8 Supercars Dunlop Series champion Cam Waters replaced Mostert at Prodrive Racing Australia. Waters had substituted for Mostert in 2015 while the latter recovered from an injury.
Will Davison joined Tekno Autosports, replacing the outgoing Shane Van Gisbergen, who joined an expanded Triple Eight Race Engineering in their third car.
Aaren Russell, having raced a wildcard entry at the 2015 Bathurst 1000, joined Erebus Motorsport for his first full-time season, replacing Ashley Walsh.
Tim Blanchard moved from Lucas Dumbrell Motorsport to Britek Motorsport. Blanchard was replaced at Lucas Dumbrell Motorsport by Andre Heimgartner. Dale Wood then moved to Nissan Motorsport, replacing James Moffat.
James Moffat joined Garry Rogers Motorsport to replace David Wall. Wall was left without a full-time drive, and competed for the team at the endurance events.
Fabian Coulthard moved from Brad Jones Racing to join the expanded DJR Team Penske. He was replaced by Tim Slade, who moved from Walkinshaw Racing, which had shut down at the end of 2015.
Lee Holdsworth was injured in a heavy crash at the start of Race 13 at the Darwin Triple Crown. His team, Team 18, originally planned to use its endurance co-driver, Karl Reindler, to replace Holdsworth at the Townsville event. However, as the team's car could not be fixed in time for the event, a deal was made with Dunlop Series driver Kurt Kostecki, with Kostecki to race for the team at the Townsville and Ipswich events using his own chassis. The team completed the build of a new car ahead of the Sydney SuperSprint and Reindler drove the car at the event, with Holdsworth making his racing return at the Sandown 500.
Aaren Russell and his sponsor Plus Fitness split with Erebus Motorsport prior to the Ipswich SuperSprint. He was replaced by Craig Baird, one of the team's endurance co-drivers, for the event. Dunlop Series racer Shae Davies, who was scheduled to contest the Enduro Cup events with the team, was announced as the full-time replacement for Russell.
There would be only one wildcard entry for the Bathurst 1000 with Nissan Motorsport entering the "SuperGirls" wildcard for Renee Gracie and Simona De Silvestro.
The 2016 calendar was released on 8 September 2015. On 1 October 2015 the calendar was revised, with Tasmania and the non-championship Australian Grand Prix races switching dates due to an updated 2016 Formula One calendar. A further revision was made on 22 March 2016, with the Sydney 500 being moved back one week to avoid clashing with other events at Sydney Olympic Park.
