What year is the fastest Mustang GT?
The fastest factory Mustang GT is the 2021 Mustang Mach 1, offering about 470 horsepower and a top speed near 168 mph. This combination makes it the quickest GT in Ford’s modern lineup.
To understand why, we’ll look at how “fastest” is measured in the Mustang GT family, from the base GT to the Mach 1, and how this model fits into Ford’s broader performance strategy. While other Mustang variants can surpass Mach 1 in certain metrics, the Mach 1 represents the peak of GT-scale performance in a production, non-Shelby package as of the early 2020s.
What makes the Mach 1 the benchmark for GT speed
Key attributes that drive its speed profile include power, gearing, aero, and stock tires. Ford tuned the Mach 1 to maximize straight-line speed and cornering stability without stepping into Shelby territory.
- Engine output: 5.0-liter V8 rated around 470 horsepower with about 410 lb-ft of torque.
- Transmission and gearing: to maximize performance, Ford offered a six-speed manual with rev-matching and an optional 10-speed automatic.
- Aero and chassis: a dedicated aero kit, revised front fascia, and improved suspension/components for better high-speed stability and handling.
- Performance numbers: roughly 0–60 mph in the low-to-mid 4-second range and a top speed around 168 mph.
- Brakes and tires: upgraded brakes and performance tires to support higher-speed driving and track work.
Before this list: The following points summarize why the Mach 1 stands out among Mustang GTs.
These elements collectively position the Mach 1 as the fastest Mustang GT in factory configuration, at least within the modern S550 generation’s GT lineup. Other GT variants offer strong performance, but rarely match the Mach 1’s top-end speed or track-focused balance.
Other GT options and how they compare
The Mustang GT family includes multiple trims and option packages that push performance in various directions, but the Mach 1 remains the standout for outright speed among GT-only configurations. Higher-performance models outside the GT umbrella—most notably the GT500 and Shelby variants—surpass the Mach 1 in power and top speed, though they are not categorized as GTs.
In summary, for factory-built GT performance, the 2021 Mach 1 holds the title as the fastest year/model within the Mustang GT lineup. If you widen the scope to the entire Mustang family, GT500 and certain Shelby models exceed Mach 1—but they are not GTs.
Summary
Short answer: 2021. The 2021 Mustang Mach 1 is widely recognized as the fastest factory Mustang GT, delivering about 470 hp and a top speed around 168 mph. While other GT variants emphasize different aspects of performance, Mach 1 represents the peak of GT-speed within Ford’s standard Mustang lineup. For outright speed beyond GT, the GT500 and Shelby models surpass it, but they sit outside the GT designation.

Which year is the fastest Mustang GT?
The Fastest Ford Mustang Available
The fastest Ford Mustang is the 2013 Shelby GT500. Its 5.8-liter supercharged V-8 engine generates 662 horsepower and 631 lb-ft of torque. It can accelerate from zero to 60 mph in just 3.5 seconds, and its braking distance from 60 mph to zero is only 101 feet.
What's faster, GT 350 or GT500?
The GT500 is significantly faster than the GT350 in terms of straight-line acceleration due to its more powerful supercharged engine. The GT500 has a 0-60 mph time of around 3.0-3.3 seconds, while the GT350 is closer to 4.0 seconds. The GT500 is designed for raw power and is better suited for drag racing, whereas the GT350 is built for track performance with an emphasis on handling and a more traditional driving experience thanks to its naturally aspirated engine and manual transmission.
