"Next generation Fiesta ST customers will benefit from innovations developed by Ford Performance for the Ford GT supercar and Focus RS hot hatchback, including high power EcoBoost and Drive Mode technologies", said Dave Pericak, global director, Ford Performance.
Unlike the GX Falcon now being raced, the Mustang's two doors marks a huge shift in the sport, allowed under the "Gen 2" rules brought in this year.
While other engine configurations are eligible under the Gen2 regulations, the Mustang will continue to use the current 5.0-litre naturally-aspirated V8.
Speaking at the launch of Ford Performance in Melbourne today Ford Australia president Graeme Whickman announced the new Fiesta ST will be an important part of the new sub-brand, sitting alongside the Ranger Raptor, Mustang and new Focus ST. "I know Australians, New Zealanders and our fans around the world will be just as excited as I am to see the Mustang take to our tracks in the world's best Touring auto racing".More news: More bodies found in Eel River Search in Mendocino County

Ford has not finished testing the new Mustang, although a formal submission is due to NASCAR this summer. Last year Ford Australia backflipped on its plan to release an official 500kW Roush supercharger kit for the Mustang.
"The Mustang nameplate is one the of the most legendary in the world and we are proud to have it lining up on our grid in 2019", Sean Seamer, Supercars CEO, said.
"We did look at other vehicles when we first thought about this, well before we even engaged with the teams or the series, but the Mustang is the right fit and its credentials in terms of the V8 are very, very strong".
Their racing Mustang will be modelled off the new 2019 model which will go on sale in Australia and New Zealand from July.
The move comes as part of the company's announcement that it will roll out the Ford Performance brand in Australia, the company once again embracing its heritage as a performance vehicle brand.
