Shelby Mustang - Defining Performance for Over 50 Years

If you are into performance vehicles, you know Carroll Shelby. A legendary racer turned builder, Carroll Shelby is synonymous with the performance and kit car industries in America. It is difficult to overstate his influence on American car culture.

Captured in the film Ford v Ferrari, Shelby's partnership with Ford revolutionized the design and production of racing and sports cars in the United States. The Shelby Mustang GT350 and GT500, released in 1965 and 1967 respectively, remain some of the most prized classic sports cars. Not only did Shelby make enormous strides when it came to weight reduction and performance. His eye for design resulted in vehicles that captured the imaginations of American drivers.

After leaving Ford to work with Dodge and Oldsmobile on their own performance vehicles, Shelby once again partnered with Ford in 2003 to design Shelby Mustangs for the new millennium. The results are easy to see, both in the Shelby GT350 and GT500, Ford's highest-performing Mustangs. But his influence is also felt across the Mustang range. Let's take a look at the equipment and features that make a Shelby Mustang.

Shelby GT350 & GT500 vs Ford Mustang GT

At first glance, Iowa buyers will notice that all Ford Mustangs share similar design cues. Shelby Mustang models have more aggressively designed front fascia, and other unique exterior touches. But many of the key differences are in the engine and under the vehicle. Below are some of the key standard features found on the Shelby Mustang GT350 and GT500.

Shelby GT350

The Shelby GT350 comes standard with a 5.2L Ti-VCT V8 with Flat Plane Crank, producing 526 horsepower. Additional performance features include:

  • 3.73 TORSEN® limited-slip rear axle
  • Differential Cooler
  • Dual Exhaust with Electronic Valves and quad tips
  • Transmission Cooler
  • TREMEC® Six-Speed Manual Transmission

The equipment above is in many ways responsible for the characteristic growl and responsiveness of Shelby Mustangs. In addition to these upgrades to the powertrain, the Shelby GT350 comes standard with a wide range of suspension and handling upgrades. These include:

  • 380 mm (15") rear brake rotors with 4-piston Brembo calipers
  • 394 mm (15.5") front brake rotors with 6-piston Brembo calipers
  • Electronic Line-Lock (track use only)
  • Independent Rear Suspension
  • Integrated Driver Control System
  • Launch control (manual transmission; track use only)
  • Selectable-effort Electric Power-Assist Steering (EPAS)
  • MagneRide® Damping System

And with wider rear wheels wrapped in premium Michelin tires, the Mustang Shelby GT350 is ready for the track or engaging drives in the countryside.

Shelby GT500

The Shelby GT500 comes with many of the same standard items as the GT350, but with notable exceptions. The transmission is replaced with a TREMEC 7-speed dual-clutch transmission, and the 5.2l V8 is supercharged. The more powerful engine produces an impressive 760 horsepower. Other interior features are upgraded as well, making the Shelby GT500 the highest-performing Mustang rolling out of Ford's factory.

Both the Shelby GT500 and GT 350 have several optional upgrades available, allowing Ames, IA buyers to go all-out on their dream car from Ames Ford Performance. But what about the Ford Mustang GT Premium? Let's look at how it compares to the impressive specs of the Shelby Mustangs.

Mustang GT Premium

While the Shelby vehicles are the true pinnacle of performance, the Ford Mustang GT is certainly no slouch. Its 5.0L Ti-VCT V8 produces 460 horsepower, and it is available with many of the performance upgrades that come standard on the Shelby GT models.

Below are the standard and optional performance & handling features on the Ford Mustang GT Premium

  • 3.55 limited-slip rear axle
  • Engine oil cooler
  • 6-Speed Manual Transmission with Rev Matching
  • 330 mm (13") rear brake rotors with single-piston calipers
  • 353 mm (14") front brake rotors with 4-piston calipers
  • Electronic Line-Lock (track use only)
  • Independent Rear Suspension
  • Launch control (manual transmission; track use only)
  • Selectable Drive Modes
  • Selectable-effort Electric Power-Assist Steering (EPAS)
  • Monotube shocks, grippy bars and rear cross-axis suspension joints
