The 2021 Ford Mustang Shelby GT500 used a hand-built supercharged 5.2-liter V8 rated at 760 horsepower and 625 lb-ft of torque, paired exclusively with a 7-speed TREMEC dual-clutch transmission. Ford developed the modern GT500 as a fastback coupe with track-focused cooling, MagneRide suspension, large Brembo brakes and available carbon-fiber track hardware.
This AutoZonic page has been rebuilt because the previous AI-generated version mixed incompatible specifications, invented trim levels, conflicting top-speed figures and equipment from other Mustang variants. The details below are based primarily on Ford and Ford Performance material.

Engine: 760 hp from Ford’s supercharged 5.2-liter V8
Ford Performance describes the modern GT500 engine as a 5.2-liter supercharged, intercooled V8. Ford’s current performance-parts documentation for the 2020-plus GT500 engine lists the factory rating at 760 horsepower and 625 lb-ft of torque.
The earlier AutoZonic version incorrectly mixed this engine with 5.8-liter and 7.0-liter GT500 claims. Those figures belong to different eras or were simply inaccurate. The 2021 car’s defining powertrain is the 5.2-liter supercharged V8.
The transmission was a 7-speed dual-clutch — not a manual or 10-speed automatic
The 2021 GT500 did not use a conventional 6-speed manual, 8-speed automatic or Mustang GT 10-speed automatic. Ford Performance paired the supercharged V8 with a 7-speed TREMEC dual-clutch transmission. Ford said the system was engineered to make extremely rapid shifts and used knowledge developed through Ford Performance programs.
This is one of the most important corrections to the old page because multiple sections previously described entirely different transmissions.
How quick was the 2021 Shelby GT500?
Ford’s own 2021 GT500 coverage described the car as reaching 60 mph in a little over three seconds and completing the quarter-mile in under 11 seconds. Exact independently measured results vary with surface, tires, weather, fuel, launch technique and test method, so AutoZonic does not present one magazine’s test number as a universal factory guarantee.
For top-speed research, see our dedicated modern Shelby GT500 top-speed guide. Ford’s aerodynamic engineering material for the modern GT500 repeatedly uses 180 mph as the high-speed reference point for rear downforce and cooling analysis. We therefore removed the old page’s unsupported 198, 200-plus and 212 mph claims for the 2020–2022 factory car.
Brakes, suspension and cooling
The modern GT500 was engineered around repeated high-performance use rather than horsepower alone. Ford documented a track-focused chassis with revised suspension geometry, active MagneRide dampers and very large front brakes. Ford’s 2021 European media material describes 420 mm front brake discs clamped by six-piston Brembo calipers.
Cooling was also a major part of the program. Ford said the GT500’s front opening volume and cooling airflow were substantially increased compared with the GT350, with multiple heat exchangers used to manage engine and drivetrain temperature under sustained load.
Carbon Fiber Track Package
Ford’s GT500 development material documents an available Carbon Fiber Track Package aimed at maximum track performance. Key hardware included:
- 20-inch exposed carbon-fiber wheels
- wider rear wheels
- Michelin Pilot Sport Cup 2 tires
- an adjustable GT4-style carbon-fiber rear wing
- more aggressive front aerodynamic hardware
- rear-seat deletion to reduce weight
Ford also offered less extreme handling-focused equipment for buyers who wanted additional chassis and aerodynamic capability without the full carbon-fiber track setup. Package availability and exact content can vary by model year, so a used-car buyer should verify the original window sticker rather than assuming every GT500 has the same hardware.
Was there a GT500 convertible?
No, not for this 2020–2022 GT500 generation. Ford’s own 2021 material describes the Shelby GT500 as a fastback coupe. The previous AutoZonic article incorrectly claimed coupe and convertible versions were both offered.
Was SYNC 4 standard on the 2021 GT500?
The old article alternated between SYNC 3 and SYNC 4. That is exactly the kind of model-year contamination we are removing from AutoZonic’s legacy AI content. When evaluating a specific used GT500, use the vehicle’s original build sheet/window sticker and Ford documentation for that VIN rather than assuming equipment from a newer Mustang applies retroactively.
2021 GT500 buying checks
- Confirm the VIN and original equipment list.
- Verify whether the car has standard wheels, handling upgrades or Carbon Fiber Track Package hardware.
- Inspect expensive carbon-fiber wheels carefully for damage if equipped.
- Check tire type, date codes, tread depth and signs of track heat cycles.
- Review brake rotor and pad condition.
- Confirm service history for the engine, DCT and cooling systems.
- Look for modifications, tuning or non-factory pulley/fuel-system changes.
- Arrange a pre-purchase inspection with a shop familiar with high-performance Mustangs.

About this article
Updated August 9, 2026 by the AutoZonic Editorial Team. This legacy AI-generated page was re-researched against Ford and Ford Performance material. Conflicting engine sizes, transmissions, body styles, invented trim names, unsupported top-speed claims and unverified package-price statements from the previous version were removed.
