When Ford brought the Shelby name back to the Mustang lineup for the 2007 model year, they didn't just slap a badge on a standard coupe. They built a heavyweight brawler designed to reclaim muscle car supremacy. The 2007 Mustang GT500 combined a supercharged iron-block V8 with a stiffened chassis and aggressive aerodynamics, changing the performance landscape of American rear-wheel-drive coupes.
If you're digging into the exact numbers behind this modern classic, you need more than a generic brochure summary. This breakdown covers the true engineering specifications, real-world handling traits, and the specific mechanical quirks that define Carroll Shelby's revival project.
Engine and Powertrain Specifications
At the heart of the 2007 Shelby GT500 sits a hand-assembled, supercharged 5.4-liter modular V8 engine. Unlike the aluminum blocks found in some contemporary sports cars, Ford Performance chose an iron block for this engine to handle immense boost pressures without distortion.
A Roots-type Eaton M125 supercharger sits atop the engine, forcing air through an air-to-water intercooler. This setup produces a factory-rated 500 horsepower at 6,000 rpm and 480 lb-ft of torque at 4,500 rpm. Power routes through a heavy-duty Tremec TR-6060 six-speed manual transmission, utilizing a dual-disc clutch that manages the heavy torque loads effectively.
- Displacement: 5.4 liters (330 cubic inches)
- Block Material: Cast iron with cross-bolted main bearing caps
- Cylinder Heads: Aluminum four-valve per cylinder DOHC
- Supercharger Boost: 8.5 psi maximum
- Redline: 6,250 rpm
Chassis and Suspension Engineering
Putting 500 horsepower to the ground requires serious chassis reinforcement. The standard S197 Mustang platform received a thorough reworking by the Special Vehicle Team (SVT) to handle the heavy front-end weight and high rotational forces.
Up front, MacPherson struts with reverse L-arms and a 34mm stabilizer bar keep the steering planted. Out back, Ford retained a solid live axle setup—a choice heavily debated by enthusiasts and automotive journalists at the time. To tame axle hop, SVT engineers added Panhard rods, stiffer springs, and custom-tuned dampers. While a multi-link independent rear suspension would have added weight and cost, the tuned live axle keeps the car predictable on smooth surfaces while demanding respect on uneven pavement.
- Front Brakes: 14-inch vented Brembo discs with four-piston aluminum calipers
- Rear Brakes: 11.8-inch vented discs with dual-piston calipers
- Steering: Power-assisted rack-and-pinion
- Wheels: 18-inch unique cast-aluminum rims
- Tires: Goodyear Eagle F1 Supercar Z-rated rubber
Performance and Track Metrics
Numbers on a spec sheet don't always tell the whole story, but the 2007 GT500 delivered numbers that shocked the segment upon its release. Zero to 60 mph happens in approximately 4.5 seconds, and the car clears the quarter-mile in roughly 12.5 seconds at over 110 mph.
Top speed sits electronically limited at 155 mph, though removing the limiter allows the car to push closer to 180 mph given enough straight tarmac. Braking performance matches the acceleration: hauling this muscle car down from 70 mph to a dead stop takes just 169 feet, thanks to the massive Brembo units.
Fuel Economy and Real-World Usability
Fuel economy was never the primary selling point for a supercharged V8 muscle car, but EPA ratings from 2007 give a clear picture of its appetite. The car is rated at 14 mpg in the city and 20 mpg on the highway. In aggressive driving scenarios, expect those figures to drop sharply.
Interior packaging remains standard Mustang fare for the era, though SVT added sport bucket seats, unique instrument gauges, and a Shelby steering wheel badge. Curb weight sits heavy at roughly 3,920 pounds, with roughly 57 percent of that weight resting over the front wheels due to the iron-block engine and heavy supercharger hardware.
Common Mechanical Considerations
Owning or maintaining a 2007 model requires attention to a few known factory characteristics.
- Supercharger Pulley Wear: Factory setups can experience belt slip or wear on the intercooler pump, leading to heat soak during extended hard driving.
- Clutch Engagement: The factory dual-disc clutch has a heavy pedal feel and can chatter if overheated in heavy traffic.
- Front-End Weight Bias: The heavy iron block makes the car prone to understeer on tight autocross courses unless suspension geometry and tire pressures are carefully dialed in.

Frequently Asked Questions
What transmission comes in the 2007 Mustang GT500?
It features a Tremec TR-6060 six-speed manual transmission. There was no automatic transmission option available for the 2007 model year.
How much does a 2007 Shelby GT500 weigh?
The car has a curb weight of approximately 3,920 pounds, largely due to its heavy iron-block V8 engine and reinforced chassis components.
Is the rear suspension independent or a live axle?
It uses a three-link solid live axle setup with a Panhard rod, specially tuned by SVT to minimize wheel hop and maintain straight-line stability under hard acceleration.
What is the stock supercharger boost pressure?
The factory Roots-type Eaton M125 supercharger runs at a maximum boost pressure of 8.5 psi in stock configuration.
