The fastest production car ever made is the 2023 Dodge Challenger SRT Demon 170. This limited-edition muscle car is the final and most extreme iteration of the Challenger line, built specifically for drag racing. It holds the official title of the quickest and fastest muscle car in history, capable of accelerating from 0 to 60 mph in an astonishing 1.66 seconds and covering the quarter-mile in 8.91 seconds at 151.17 mph when using E85 fuel. This performance surpasses even the legendary Dodge Challenger SRT Demon from 2018.
The Demon 170's incredible speed comes from a supercharged 6.2-liter Hemi V8 engine that produces 1,025 horsepower on E85 ethanol fuel. A key feature is its TransBrake, which allows the engine to build up boost pressure while the car is stationary, enabling a violent, tire-shredding launch. While other modern Dodges like the Hellcat Redeye variants are extremely fast, the Demon 170 stands alone at the top of the performance ladder.
It's crucial to note that the Demon 170 is a specialized, street-legal drag car. Its performance is highly dependent on using the correct high-octane fuel and drag radial tires. For context, here’s how it compares to other high-performance Dodges:
| Dodge Model | Engine | Horsepower | 0-60 mph (est.) | Quarter-Mile Time |
|---|---|---|---|---|
| Challenger SRT Demon 170 (2023) | Supercharged 6.2L V8 | 1,025 hp (E85) | 1.66 sec | 8.91 sec @ 151 mph |
| Challenger SRT Demon (2018) | Supercharged 6.2L V8 | 840 hp | 2.3 sec | 9.65 sec @ 140 mph |
| Charger SRT Hellcat Redeye (2021-2023) | Supercharged 6.2L V8 | 797 hp | 3.4 sec | 10.6 sec @ 131 mph |
| Challenger SRT Hellcat (Widebody) | Supercharged 6.2L V8 | 717 hp | 3.4 sec | 10.8 sec @ 131 mph |
| Dodge Viper ACR (2017) | 8.4L V10 | 645 hp | 3.3 sec | 10.8 sec @ 128 mph |

If we're talking pure, straight-line speed, it's the Demon 170, no question. That car is just a rocket. I remember seeing the numbers when it dropped – a sub-9-second quarter-mile right from the factory is just insane. It makes the regular Hellcat feel almost tame. But honestly, for most people, any of the Hellcat models are more than fast enough. The Demon is a special beast for the drag strip.

You have to look at the context. The Viper ACR is faster around a track, but for outright acceleration in a straight line, the title goes to the Challenger SRT Demon 170. It's the ultimate expression of Dodge's "horsepower war" philosophy. The key is its specialized design: it uses E85 fuel for maximum power and comes with drag radials from the factory. It's not just fast; it's a purpose-built machine that dominates the quarter-mile.

Forget everything else. The answer is the 2023 Challenger Demon 170. It's the king. They built it as the last hurrah for the current Challenger, and it's basically a drag car you can legally drive on the street. The numbers speak for themselves: over 1,000 horsepower and it can hit 60 mph in under two seconds. That's hypercar territory, but for a fraction of the price. It’s the fastest thing has ever unleashed on the public.

While the classic Viper holds a special place for its raw, analog feel, the title of "fastest" in terms of acceleration belongs to the modern supercharged heroes. The crown is worn by the Challenger SRT Demon 170. Its ability to launch is unlike any other production car has made, thanks to technology like the TransBrake that pre-loads the drivetrain. It represents the peak of what Dodge could achieve with its front-engine, rear-wheel-drive platform before moving to electric vehicles.
