The fastest muscle car in the world is the Dodge Challenger SRT Demon 170, which has 1,025 hp on E85 fuel and ran an NHRA-certified quarter mile in 8.91 seconds at 151.17 mph. It also leads the straight-line list in 2026, and Ford's supercharged Mustangs are the strongest challengers. This top 5 ranks production muscle cars by straight-line speed first and then by track pace.

|---|---|---|---|
| 1 | Dodge Challenger SRT Demon 170 | 1,025 hp, 8.91 s quarter mile | Built for 2023 |
| 2 | Ford Mustang GTD | 6:52.072 Nürburgring (May 2025) | In production, 2025 model year |

What counts as a muscle car?
A muscle car is a high-horsepower American coupe, traditionally with rear-wheel drive and a V8. The golden age was the 1960s and 1970s, when Ford, Chevrolet, Chrysler and AMC competed to build the fastest, loudest and best-looking cars. Some prefer to call the 1960s originals “classics”, but the modern line is still very much alive.
How we ranked the cars
We ranked on verified performance figures: quarter-mile time, horsepower and lap times. Where a factory number could be compared directly, we used it. Where it could not, we ranked on power and track pace and say so.
1. Dodge Challenger SRT Demon 170
Power: 1,025 hp on E85 | Quarter mile: 8.91 s at 151.17 mph
The Demon 170 is the quickest production muscle car. Its supercharged 6.2-liter V8 produces 1,025 hp on E85 fuel. The quarter-mile time of 8.91 seconds at 151.17 mph is NHRA certified in stock form. Dodge also claims a 0 to 60 mph time of 1.66 seconds, though that figure uses a rollout. It also recorded 2.004 g of lateral grip, the highest for any production car.
The Challenger line ended on 22 December 2023, after Dodge announced the end of Challenger, Charger and Chrysler 300 production, so the Demon 170 is a final chapter. Why it ranks here: the best certified straight-line numbers of any muscle car.
2. Ford Mustang GTD
Power: supercharged 5.2-liter Predator V8 | Nürburgring: 6:52.072 (May 2025)
Ford unveiled the Mustang GTD in August 2023 as a street version of its GT3 race car, for the 2025 model year. It uses the supercharged 5.2-liter Predator V8 from the previous Shelby GT500. In December 2024, it lapped the Nürburgring in 6:57.685, the first American production car under seven minutes, and improved to 6:52.072 in May 2025. In April 2026, Ford unveiled a GTD Competition model that set 6:40.835 and is pre-production.
Placement: the best track car in the muscle class, but a track special rather than a straight-line king.
3. Ford Mustang Dark Horse SC
Power: 795 hp | Torque: 660 lb-ft
Ford revealed the Dark Horse SC on 15 January 2026. It has the supercharged 5.2-liter Predator V8 and produces 795 hp and 660 lb-ft of torque. Ford considers it the spiritual successor to the sixth-generation Shelby GT500. It is a track-focused variant of the Dark Horse.
Our verdict: a new car that is more powerful than the GT500 it replaces.
4. Ford Shelby GT500
Power: 760 hp | Torque: 625 lb-ft
The 2020 GT500 was unveiled at the January 2019 Detroit show. It has a hand-built 5.2-liter Predator V8 with a 2.65-liter Roots-type supercharger and a seven-speed dual-clutch gearbox. It was sold from 2020 to 2022.
The case for it: a modern classic, now overshadowed by the newer Dark Horse SC.
5. Chevrolet Camaro ZL1
Power: 650 hp | Top speed: 198 mph
The ZL1 arrived in 2017 with a supercharged 6.2-liter LT4 V8 producing 650 hp and 650 lb-ft. Chevrolet quotes 0 to 60 mph in 3.5 seconds and a quarter mile of 11.4 seconds at 127 mph. Production of the sixth-generation Camaro ended in December 2023.
Rank logic: the best-balanced all-rounder in the list, though the least powerful.
What happened to the old list?
Our 2017 list included the 1969 Plymouth Road Runner, the 1966 Corvette 427, the 1990 Corvette ZR1, the 427 Shelby Cobra and the 1997 Dodge Viper GTS. Most of those are sports cars or collector pieces rather than fast muscle cars by today's standards, so we moved to modern production numbers. The old school still has legends: a 1967 Shelby GT500 Super Snake, with a 650 hp 427 engine, reached 170 mph in a demonstration.
What is next for American muscle?
The new Dodge Charger comes in electric and gasoline versions. The Charger Daytona Scat Pack has 670 hp from two electric motors. The gasoline Charger Sixpack uses a 3.0-liter twin-turbo inline-six, with the Scat Pack at 550 hp. On 7 August 2026, Dodge announced a Super Bee for the 2027 model year with 600 hp. None of them has beaten the Demon 170 yet.

How we put this list together
We used manufacturer and certified performance figures and production dates checked in October 2026. Different cars were tested in different ways, so rankings mix quarter-mile, power and track times and we say which applies.
