Ford’s Flat Rock, Michigan plant this week began churning out the all-new 2015 Ford Mustang, the final candle on the pony car’s 50th birthday cake.

Job 1 for the all-new Mustang is here with a celebration marking the official start of production for the 2015 Mustang, attended by Ford executives, designers, engineers, and UAW dignitaries.

The 2015 Mustang fastback EcoBoost, V6 and 5.0 liter V8 GT models are the first to start rolling off the line which also builds the Ford Fusion.

The Flat Rock Plant, formally known as the Auto Alliance International was once shared by Ford and Mazda. Most recently the last-generation Mustang and Mazda 6 sedan had been built there before the two companies separated.

The first batches of production for the 2015 Ford Mustang will be primarily for the North American market with global export models slowly phasing in over the coming twelve month period.

While the line has actually been moving for a short time, Job 1 is the official moment where cars are actually released to start shipping beyond the chain link fence.

What this means to all of us out here is that the 2015 Ford Mustang is being loaded on rail cars right now and is bound for your local dealers in the coming weeks. Be on the look out! For more news and test drives of Fords and Mustangs see our partner channel
