2019 Supercars Championship

[36][37] Tickford Racing and DJR Team Penske oversaw the development of the car, with Ford Performance providing additional technical support.

[41] The homologation process required modifications to the bodywork to fit the series' control chassis, but the car continued to use the V8 engine used by the FG X Falcon.

[42][43] The decision to return the Mustang to the series was made as Australia's domestic production of the Ford Falcon ceased in 2016.

[46] Nissan withdrew its factory support from the championship at the end of 2018 as the company elected to change its global motorsport strategy and focus on its Formula E entry.

Caruso's seat was filled by Garry Jacobson, who made his full time début in the championship with the team.

[59] Jones made his full time début in the championship, after having previously entered as a wildcard at selected events in 2017 and 2018.

[61][62] Holdsworth took Winterbottom's place at Tickford Racing,[63] while Stanaway moved to Garry Rogers Motorsport to replace Garth Tander.

[21] Richie Stanaway was withdrawn halfway through the Winton SuperSprint and missed the next three rounds, due to a neck injury.

He was replaced for the remainder of the round, and the following Darwin Triple Crown by Chris Pither, who had already been nominated as Stanaway's partner for the endurance races.

[65] Changes to the Formula One calendar meant that the Australian Grand Prix was run earlier in the year than it was in 2018, and thus the Supercars support races was also moved forward.
