10 Most Iconic Shelby Mustangs of All Time
From the track-tuned GT350R to the 900-horsepower King of the Road, these are the Shelby Mustangs that defined performance across generations.
1. 1965 Shelby GT350
The original race-bred Mustang
- Engine: 289 cu in (4.7L) HiPo V8
- Power: 306 hp
- 0–60 mph: ~6.5 seconds
- Production: 562 units
Carroll Shelby’s first Mustang creation transformed Ford’s pony car into a bona fide track weapon. With reduced weight, Koni shocks, a Detroit Locker rear axle, and no rear seats in early “R” spec variants, the 1965 GT350 was raw, agile, and loud — a pure racer for the street.
2. 1966 Shelby GT350-H “Rent-A-Racer”
Performance you could rent (and sometimes race)
- Engine: Same as 1965 GT350
- Power: 306 hp
- 0–60 mph: ~6.5 seconds
- Production: ~1,000 units (Hertz exclusive)
In a wild marketing experiment, Shelby teamed up with Hertz to offer GT350s through its rental program. Some weekend warriors would rent one on Friday, drag race it on Saturday, and return it Sunday — sometimes with bald tires and a roll cage welded in. The black-and-gold livery remains legendary.
3. 1967 Shelby GT500
Big block, big attitude
- Engine: 428 cu in (7.0L) Police Interceptor V8
- Power: 355 hp (underrated)
- 0–60 mph: ~6.2 seconds
- Production: 2,048 units
1967 marked a styling overhaul, and Shelby went bigger — literally. The GT500 introduced the 428 big-block, fiberglass body panels, and a more aggressive aesthetic. Though heavier than the GT350, its torque-rich engine made it a street bruiser. This was Shelby’s answer to the muscle car era.
4. 1968 Shelby GT500KR (“King of the Road”)
More than a name — a statement
- Engine: 428 Cobra Jet V8
- Power: 335 hp (underrated; actual was closer to 400 hp)
- 0–60 mph: ~6.0 seconds
- Production: 1,570 fastbacks and 517 convertibles
Ford introduced the potent 428 Cobra Jet in mid-1968, and Shelby wasted no time applying it to the GT500. Marketing dubbed it the "King of the Road" — a jab at Chevy’s use of the same name for the Camaro. Despite its inflated weight, it could seriously move and remains one of the most collectible Shelbys.
5. 2007 Shelby GT500 (S197)
The supercharged comeback
- Engine: 5.4L supercharged V8
- Power: 500 hp
- 0–60 mph: ~4.5 seconds
- Top Speed: 155 mph (electronically limited)
- Production: ~10,847 coupes in 2007
After a 35-year hiatus, Shelby and Ford reunited with the S197-based GT500. It sported a blown 5.4L iron-block V8 derived from the Ford GT and a Tremec 6-speed manual. Though heavy, it offered serious straight-line speed and resurrected the Shelby badge for a new generation.
6. 2011–2012 Shelby GT500 (Aluminum Block Upgrade)
Lighter and faster evolution
- Engine: 5.4L supercharged aluminum V8
- Power: 550 hp
- 0–60 mph: ~4.2 seconds
- Top Speed: 180+ mph (with limiter removed)
In 2011, the GT500 received a significant update — an aluminum engine block that shaved 100+ pounds off the front end, improving handling. Power jumped, and the car began to feel more balanced. 2012 also saw the limited-run GT500 Super Snake, which could be optioned with over 800 hp.
7. 2013–2014 Shelby GT500
662 horsepower from the factory
- Engine: 5.8L Trinity supercharged V8
- Power: 662 hp / 631 lb-ft
- 0–60 mph: 3.5 seconds
- Top Speed: 202 mph
- Production: ~10,000 units (2013–2014 combined)
The final Shelby Mustang of the S197 generation was an absolute monster. It featured the most powerful production V8 in the world at the time. With a 7,000 rpm redline, launch control, and an optional Track Pack, it could shame supercars at half the price. The GT500 had truly gone nuclear.
8. 2020–2022 Shelby GT500 (S550)
Track-tuned, tech-packed, and brutally fast
- Engine: 5.2L “Predator” supercharged V8
- Power: 760 hp / 625 lb-ft
- 0–60 mph: 3.3 seconds
- Top Speed: 180 mph (electronically limited)
- Production: ~19,500 units total
The modern GT500 was no longer just a straight-line beast — it was a corner carver, too. With a TREMEC 7-speed dual-clutch, MagneRide suspension, and track-focused variants like the Carbon Fiber Track Pack, it became one of the most capable Shelbys ever — and one of the best American cars of its decade.
9. 2022 Shelby GT500KR (King of the Road Reborn)
A modern limited-edition legacy
- Engine: 5.2L supercharged V8 (upgraded)
- Power: 900+ hp (on 93 octane)
- 0–60 mph: Sub-3.5 seconds
- Production: 225 units worldwide
To celebrate the 60th anniversary of Shelby American, the KR name returned. Based on the S550 GT500, this limited-edition car featured significant performance upgrades, carbon fiber components, and Shelby-specific tuning. It was rarer, louder, and more powerful than any road-going Shelby before it.
10. Shelby GT350 / GT350R (2015–2020)
The flat-plane screamer
- Engine: 5.2L “Voodoo” flat-plane crank V8
- Power: 526 hp / 429 lb-ft Redline: 8,250 rpm
- Top Speed: 180+ mph
- Production: ~37,000 (GT350) and ~5,500 (GT350R)
While not as powerful as the GT500, the S550-generation GT350 and GT350R were arguably more rewarding to drive. The Voodoo V8 was unlike anything ever fitted to a Mustang — high-revving, exotic in tone, and paired with a six-speed manual. The R version deleted rear seats and added carbon wheels for track dominance.
