Petty's Garage builds limited edition Mustangs with up to 727 horsepower

The NASCAR great's speed shop will construct 300 high-horsepower 'Stangs with a starting cost of $67,495.

The 2016 Mustang GT King Premier Convertible.


Richard "The King" Petty's speed shop in North Carolina is no stranger to building ludicrous, modified versions of standard street cars. This time around, Petty's Garage has turned its attention to the 2016 Ford Mustang -- the result is a small-batch Mustang King Edition with enough horsepower to make any enthusiast a little antsy.

The Mustang King starts life as a bone stock, 435-horsepower Mustang GT. From there, Petty's Garage adds several performance-enhancing modifications, including a MagnaFlow exhaust, a revised air intake system, a Ford Performance supercharger and the computer calibrations required to make everything work. These items combine to boost the Mustang's power output to 670 horsepower.

To ensure the newly modified motor puts that power to the ground effectively, Petty's Garage also modifies the drivetrain, including Ford Performance halfshafts, a new rear axle and adjustable antiroll bars. The King Mustangs also feature multiple aesthetics upgrades, including larger HRE wheels with summer tires, a center-mounted exhaust outlet and a custom rear diffuser. Each model also comes with its own custom dash plate, signed by The King himself.

And that's just the base model. The shop will also create 57 King Premier models in both coupe and convertible form. The Premier edition includes larger brakes, a custom leather-trimmed interior, and "Petty Blue" paint stripes and accents.

No matter which variant you prefer, the car will come with a three-year, 36,000-mile limited powertrain warranty, which should ease some concerns. Furthermore, buyers can opt for additional modifications, including coil-over-type racing suspension and a smaller supercharger pulley that boosts output to a Hellcat-shaming 727 horsepower. Don't expect those upgrades to be cheap, though.

In fact, nothing about this car is cheap. The base King edition starts at $67,495 (directly converted, about £43,995 or AU$93,567), and the Premier will run you a whopping $90,495 (£59,006, AU$125,424) -- before any options are included. That said, if you have the means, a trip to the Ford dealer is all it takes to order one. You might want to hurry, though; the total production run is limited to 300 models.
