Upgraded MY21.5 Ford Mustang released Upgraded MY21.5 Ford Mustang released May 25, 2021 Australia’s top-selling sports car gains new tech and colours, for a price An upgraded MY21.5 version of the popular Ford Mustang muscle car is now on sale, bringing minor technical, cosmetic and pricing increases. The sixth-generation Ford Mustang now comes with more connectivity and paint colour choices, but Australia’s (and the world’s) favourite sports car is now also slightly more expensive across the board. The only technical upgrade for the MY21.5 update is the addition of an embedded modem to support FordPass Connect, as seen on the 2021 Ford Ranger, allowing owners to locate, un/lock, start and switch on the climate control system of their vehicle remotely via the FordPass smartphone app.
