Ford Mustang 2013 Shelby GT500 Chases 200 MPH!

Two hundred miles an hour used to be a number reserved for exotics, not something you ordered at a Ford dealership. Then SVT dropped a 5.8-liter supercharged V8 into the 2013 Mustang and produced 662 horsepower — the most powerful production V8 in the world at the time. It came with one transmission choice and a solid rear axle. Read on for how Ford made all of that work.

There is a moment in the history of every performance car company where the engineers stop being reasonable, and for Ford’s Special Vehicle Team that moment produced a Mustang with more horsepower than any production V8 on earth. Not the most powerful Mustang, not the most powerful American car — the most powerful production V8 anywhere, from anyone, at the time it launched. It reached that figure with a live rear axle, a single available transmission, and a price that undercut the European machinery it was designed to humiliate. Understanding how Ford got there means looking past the headline number at some genuinely unusual engineering decisions, several of which had never appeared in a mass-production engine before.

Trinity: An Aluminum Block With Sprayed-On Cylinder Walls

The engine was internally known as Trinity, a 5.8-liter supercharged V8 producing 662 horsepower and 631 lb-ft of torque. What made it interesting was not the displacement but the block. Ford used an aluminum casting and, rather than pressing in conventional iron cylinder liners, applied a plasma transfer wire arc coating — effectively spraying a thin, hard, low-friction layer directly onto the bore walls. The technique saved weight, improved heat transfer out of the cylinder, and reduced friction. It had been used in racing and in limited production before, but never on an engine sold in these volumes at this price point.

2.3 Liters of Supercharger and the Heat It Makes

Feeding it was a 2.3-liter Eaton twin-vortices supercharger running significant boost, and the supporting cast mattered as much as the blower itself. Ford fitted a substantially upgraded cooling package, a high-capacity fuel system, forged internals, and a cylinder head design revised to handle the thermal load. Anyone who has tried to make five hundred honest horsepower on a road car understands that generating the power is the easy half; getting the heat back out reliably, over and over, without detonation, is the part that separates a dyno queen from something a manufacturer will warranty.

One Gearbox, No Discussion

Ford offered exactly one transmission: a six-speed Tremec manual. There was no automatic, no dual-clutch, no paddle option, and that decision tells you precisely who the car was built for. Buyers could specify different final drive ratios depending on whether they cared more about acceleration or top speed, and that choice materially changed the car’s character. The shorter gear made it savage off the line; the taller gear was mandatory for anyone who wanted to chase the top-speed figure. It is one of the few modern performance cars where the axle ratio on the window sticker genuinely determines what kind of car you bought.

662 Horsepower Through a Live Rear Axle

The engineering problem nobody talks about is the rear suspension. The S197 Mustang used a solid rear axle located by control arms and a Panhard rod — a fundamentally old-school arrangement being asked to put 631 lb-ft of torque to the ground. Ford’s solution involved careful damper tuning, adjustable Bilstein shocks on the Performance Package, launch control that managed engine torque during the first few feet, and a Torsen limited-slip differential on Track Package cars. It works far better than physics suggests it should. It also means the car remains genuinely challenging on broken pavement in a way its independently sprung successor is not.

The Track Package and Its Three Extra Coolers

The Track Package existed because Ford knew what customers would do. It added an engine oil cooler, a differential cooler, and a transmission cooler — three separate heat exchangers whose entire purpose was surviving repeated hard laps without the car quietly derating itself. Brakes were Brembo six-piston units up front clamping enormous rotors, sized for a car that weighs what this one weighs and accelerates the way it does. It is a package that only makes sense if you assume the buyer is going to a road course, which a surprising number of GT500 owners actually did.

What It Actually Took to See 202

The two hundred mile per hour question needs a careful answer. SVT’s chief engineer publicly put the car’s top speed at right around 202 miles per hour, achieved with the taller final drive, correct tires, and enough road to get there — an unofficial figure rather than a certified one, but a credible one from the person who signed off on the car. Reaching it required aerodynamic work most buyers never think about: underbody panels, a revised front fascia, and cooling openings sized to feed the engine at speed without generating lift. Ford advertised a top speed above two hundred, and nobody in the industry seriously disputed it.

Fifty-Five Thousand Dollars Worth of Embarrassment

The price is what made the whole exercise absurd. The 2013 GT500 opened right around fifty-five thousand dollars — roughly the cost of a well-optioned mid-range German sedan, and a fraction of what any comparably fast exotic commanded. Zero to sixty took about 3.5 seconds, the quarter mile disappeared in the low elevens, and it did that while carrying a warranty and a dealer network in every mid-sized town in America. For a specific kind of buyer, that combination has never been improved upon, which explains why these cars retained value far better than most modern Mustangs.

The End of the Supercharged Shelby

It also marked an ending. The 5.8-liter Trinity ran for 2013 and 2014 only, and when the S550 generation arrived, Ford took the Shelby name in a completely different direction: a naturally aspirated 5.2-liter with a flat-plane crankshaft, revving past eight thousand, prioritising response and road-course behaviour over brute output. Supercharging did not return to a Shelby Mustang until later still, and by then the philosophy had shifted again. The 2013 car stands as the last, loudest expression of the idea that the answer to every question is more boost.

Living With One Today

Owning one now means accepting a few realities. These cars are hard on rear tires in a way that surprises first-time owners, and clutch life depends enormously on how the car has been driven. The supercharger requires periodic attention, and heat management remains the thing to watch on track. Many have been modified, and a stock, documented, low-mileage example is now genuinely difficult to find. What has not changed is the front end — that wide, low, deliberately menacing fascia is still one of the best-resolved faces Ford has ever put on a Mustang, and it looks no less serious more than a decade later.
