The Ford Mustang->ke428 is no stranger to receiving the limited edition treatment. Just this year, we’ve already seen a handful of them, most notably the Shelby GT350R Mustang Cattle Baron’s Ball Edition and the Mustang Convertible Neiman Marcus Edition. These are just two examples of unique Mustangs that have recently come to our attention. Now, Ford->ke31 is proud to announce the newest limited edition Mustang, and for this one, it tapped an old friend to help in its customization. It’s called the Mustang GT King Edition by Petty’s Garage, and it’s the latest in a long line of customized Mustangs that have gone to the hands of Richard Petty’s aftermarket performance shop.

The Mustang GT King Edition actually comes in three different variants, each with limited availability. Despite having different quantities, all three serialized, limited-production Petty Mustang GT variants went thought the high-quality customization process that Petty’s Garage is famous for. They have exterior modifications, interior upgrades, and most importantly, engine modifications that shoot the muscle car’s output straight into the stratosphere.

The end result certainly speaks for itself. Anytime Petty’s Garage is involved in customizing a Ford Mustang, you know something special will come out of it.

Exterior

The most noticeable aspect of the Mustang GT’s customized exterior is its color scheme -- specifically the use of the iconic Petty blue paint finish on the hood stripes and body cladding to complement the muscle car’s dominant black color. Red and white stripes covered in crushed and tumbled glass in clear coat were used to outline the blue stripes. The same Petty Blue paint finish was also used on the new set of custom, matte black, 20-inch HRE wheels. These same wheels are wrapped in standard-issue Continental Extreme Performance summer tires.

In addition to the unique paint finish adorning these limited edition Mustangs, Petty’s Garage also installed a custom rear diffuser and a center-mounted exhaust designed by no less than Richard Petty himself.

Interior

The interior of the Mustang GT was largely kept in stock form. There are a few upgrades, but nothing to the extent of what we usually expect whenever we see a custom tuned Mustang GT. For the most part, the only noticeable changes are the leather-trimmed interior, custom gear knob, embroidered head restraints, new floor mats, and a special plate on the dashboard carrying the signature of Richard Petty himself.

Drivetrain

Despite coming in three unique editions, the base model is still the 5.0-liter V-8-powered Ford Mustang GT. To give it the power and performance boost it needed, Petty’s Garage slapped a Ford Performance supercharger to the V-8 mill. The presence of the supercharger alone already adds 235 horsepower to the Mustang GT’s standard output of 435 horsepower, bringing the total up to 670 horsepower. Petty’s Garage didn't stop there however. as it also added a cold-air intake, a MagnaFlow exhaust, and a custom engine calibration to further increase the V-8’s output to 727 horsepower.

That much power on a Mustang GT needs to at least be corralled to keep the whole car from falling apart. Petty’s Garage addressed that by installing extreme-duty TrakPak Ford Performance half shafts, three-way adjustable sway bars on the front and rear, and a rear axle upgrade.

Prices

Petty's Garage has priced the Mustang GT King Edition at $67,495 while the Mustang GT King Premier Edition retails for $90,495. Each of these models will only be available in limited quantities. The Mustang GT King Edition, for example, will only have 243 units while the Mustang GT King Premier Edition will be limited to just 43 units. But the rarest of the variants is the Mustang GT Premier Convertible. Only 14 of these bad boys will be made available to the public.

Those interested in any of these limited edition Mustang GTs can already place their orders through their local Ford dealerships.

Competition

Ford Mustang by Ford Racing and Roush Performance

Ford Mustangs are usually one of the most customized cars in the market today because there’s no shortage of aftermarket companies that offer tuning programs for the iconic muscle car. In some cases, Ford even partners with these custom shops similar to its partnership with Petty’s Garage. One example is this Ford Mustang that Ford Racing and Roush Performance worked on.

It may not be as extensive as the Mustang GT that Petty’s Garage worked on, but it’s still fully certified as a custom Mustang because of a new supercharger kit that was actually co-developed by Ford and Roush specifically for the pony car’s 5.0-liter Coyote V-8 engine. The resulting output reaches 600 horsepower, which isn’t quite to the level that Petty’s Garage managed to coax out of its own custom program, but impressive enough to mention the 165-horsepower increase from the standard Mustang.

Ford Mustang HPE700 by Hennessey

If it’s power that you really want out of your Ford Mustang, then Hennessey might be the aftermarket company to call to get your pony fix. The celebrated American tuner is in the business of making dreams come true and in this particular instance, those pining to own a Mustang that can do 700 horsepower without breaking a sweat know who to call.

Hennessey's program for the muscle car was actually released in October 2014, but even a year later, it remains as one of the most impressive aftermarket programs for the Mustang. Hennessey created a comprehensive kit that includes exterior, interior, and performance upgrades that brings the car’s output up to a ballsy 700 horsepower.

The good news, at least at that time, was that each of these Mustangs only cost $59,500. The bad news is that Hennessey only made 500 units of the car and there’s a good chance that all of them are already accounted for.

Conclusion

I don’t need any convincing when it comes to Petty’s Garage. I know full well what Richard Petty and his merry band of designers and engineers are capable of when you present them with a standard Ford Mustang and tell them to go crazy with it. This new program for the Mustang GT is exactly what you’d expect from the custom shop. It has a very charismatic exterior appearance that really brings out the edginess of the Mustang GT’s appearance. The interior didn’t get as many refinements as I thought, but it still works for me. But the real treat of this serialized, limited edition Mustang GT is the work that was done under its hood. That’s the meal ticket of this program and it’s no surprise that Petty’s Garage recognized that off the bat and took full advantage of it.
