Remaining 2021 Ford Mustang Mach 1 and S550 Shelby GT500 orders will be punted to the 2022 model year due to supply shortages, according to Ford dealers. One salesperson, named Zach, has made the setback public, as a forum post from on Mustang 6G reads as follows:
We just received official word today that some Mustangs/GT500s for the 2021 model year will be cancelled because of commodity shortages. Ford will be rescheduling these orders for 2022. The team at Ford is exploring options to protect retail customers, with more information that will be available soon.
Sorry to say that we are going to have 12 total Mach 1s that were for retail customers get cancelled. @Jay at Granger will be reaching out over the next couple days for our customers who have been impacted by the change.
This is the first time we’ve experienced something like this, in this magnitude and I can certainly understand the frustration of those of you who have ordered. We are going to lock in our discount and I would encourage those of you who visit with Jay to get the 2022 order placed ASAP. It sounds like receipt of the 2022 order will determine timing of delivery.
Again, I appreciate your understanding and patience with this unforseen issue.

Ford Motor Company officials didn’t issue a response to MC&T at the time of this writing. While not immediately clear which supply shortage is affecting the 2021 Ford Mustang Mach 1 and Shelby GT500, the two share a rear axle cooling system and lower diffuser.
S550 Ford Mustang Mach 1
The 2021 Ford Mustang Mach 1 is effectively tasked with replacing three products: the Mustang GT PP2, the Mustang Bullitt, and the legendary Mustang Shelby GT350. It does so by retaining the tried-and-true 5.0L Coyote V8 engine, while borrowing various parts bin components from both the Shelby and Bullitt. The MSRP for the S550 2021 Ford Mustang Mach 1 started at $51,720, plus $1,195 destination and delivery charge. This effectively split the difference between the outgoing Mustang Bullitt that stickered at $46,705 and the beloved Mustang Shelby GT350, which carried an MSRP of $59,140.
Recently, it was announced to dealers that the Coyote V8 Mustangs (the GT and Mach 1) would be dialed back by 10 horsepower as a result of emissions regulation.
S550 Ford Mustang Shelby GT500
The ultimate Mustang with the ultimate price tag, the Ford Mustang Shelby GT500 delivers 760 horsepower via the Predator V8 engine; a supercharged 5.2L DOHC V8 that is probably the loudest motor we’ve ever tested in a production car. It’s made even more extreme thanks to the $18,500 Carbon Fiber Track Package, which pulls out the rear seats, adds a carbon fiber wing and canards, carbon fiber wheels, massive Brembo brakes, and Michelin Pilot Sport Cup 2 tires.
A step below that is the recently announced Carbon Fiber Handling Package. Priced from $10,000, the pack adds 20-inch carbon fiber wheels that are painted black, new-for-2021 adjustable strut top mounts, a catch can, a Gurney flap in the rear, splitter wickers and a wheel locking kit. It keeps the rear seats, and Michelin Pilot Sport 4S tires on the standard S550 Ford Mustang Shelby GT500.
There won’t be a convertible version.
