Horsepower is a statement. Over the years, Ford has packed some serious muscle into the Mustang badge. These weren’t your average weekend cruisers. They came with bigger engines and a reputation to back them up. What follows is a breakdown of the most high-powered Mustangs to ever wear the name.

2022 Shelby GT500KR: 900+ HP

Back in 2022, Shelby revived a legend and didn’t hold back. The GT500KR hit the streets with over 900 horsepower under the hood, powered by a 3.8L Whipple supercharger. Only 225 were built worldwide. Carbon-fiber panels and that King of the Road legacy made it a certified brute.

2020 Shelby GT500: 760 HP

The performance took center stage when Ford rolled out the 2020 GT500. Its 5.2L V8 was hand-assembled and packed a jaw-dropping 760 HP. The dual-clutch transmission snapped through gears with near-instant precision, making this the fastest street-legal Mustang ever. Zero to 60? Just 3.3 seconds flat.

2014 Shelby GT500 Super Snake: 850 HP

The Super Snake name doesn’t get tossed around lightly, and in 2014, Shelby brought the heat. Starting with a GT500 and pushing it further with an 850 HP Kenne Bell blower, this model was hand-crafted for power junkies. Track-tuned cooling and rare production numbers gave it instant collector status.

2013 Shelby GT500: 662 HP

Ford made history in 2013 by releasing the first factory Mustang to top 200 mph. The GT500 was the most powerful production Mustang of its time. With a 14 psi supercharger and solid rear axle, it blended brute force with old-school charm.

2012 Shelby 1000: 950 HP

For those who think 700 HP is impressive, the Shelby 1000 says hello. In 2012, Shelby American took a GT500 and rebuilt it into a 950-HP beast for the street and over 1,100 for the track. It came with a near-$200,000 price tag and required a full drivetrain overhaul to handle all that power.

2008 Shelby GT500KR: 540 HP

The 2008 GT500KR wasn’t just a nod to history; it was a 540-HP celebration of it. Built to honor the original King of the Road’s 40th anniversary, it came with a carbon-fiber hood and limited production of just over 1,000 units. It was pure muscle with a purpose.

1995 SVT Cobra R: 300 HP

By 1995, the Mustang needed something special for the crowd. Ford SVT delivered with the Cobra R—a stripped-down, no-frills track weapon. Its 5.8L Windsor V8 made it the fastest Mustang of the ’90s, and everyone rolled off the line in stark white.

1969 Boss 429: 375 HP

The Boss 429 was born for NASCAR. In 1969, Ford crammed a 429 cubic-inch V8 with semi-hemi heads into the Mustang and called it homologation. Less than 1,400 made it out alive. That gaping hood scoop fed real air to real race parts.

1968 Shelby GT500KR: 335 HP

Shelby’s 1968 GT500KR looked luxurious, but there was power lurking beneath the polish. Rated at 335 HP, the Cobra Jet engine actually made closer to 400. A wood-trimmed interior and aggressive styling added flair,  and its performance set the tone for the high-output Shelby models that followed.

1965 Shelby GT350R: 360 HP

When Carroll Shelby set out to build a race Mustang in 1965, he gave the world the GT350R. Stripped of creature comforts and weighing under 2,800 lbs, it dominated SCCA racing from the start. With fewer than 40 units produced, it’s among the rarest and rawest Mustangs ever built for pure speed.
