All parts necessary to build your own GT-H from a standard GT are available online through Ford Racing Parts.

Speed Read
Vehicle Tested:
2006 Ford Mustang GT Premium 2dr Coupe (4.6L 8cyl 5M)

What Works:
Aggressive styling, throaty exhaust note, wheelspin 'til the cows come home.

What Needs Work:
Sporty suspension is creaky and too firm for long highway drives, disabling traction control is a minor inconvenience.

Bottom Line:
The GT-H is just a paper clip away from the smoky burnouts and general rubber-burning mayhem for which it was built.

Featured Specs
"Permanent" traction control
Power upgrade package
Handling package
Performance X-Pipe

Wild mustangs once ran free across the plains of this great country until man came up with the idea to saddle and domesticate them. The 2006 Ford Mustang Shelby GT-H story is that of a pony car escaping to freedom, only to realize it's still wearing a saddle.

After 40 years, Hertz and Shelby team up again to bring the Mustang GT-H experience to renters at select Hertz locations. At $300/day (not including premium fuel) the Shelby received a lackluster reception by the public, so prices were lowered. We rented one outside of Los Angeles International Airport at its current $129/day rate.

What's great about the GT-H is that it's nearly identical to the upcoming 2007 Shelby GT. The only exceptions: the cowl-inducted-style hood of the Hertz is replaced by a forward-facing hood scoop, P235/55ZR17 tires are upgraded to 18-inchers and unlike the four-speed automatic-only rent-a-racer, the '07 variant offers a five-speed manual transmission.

First things first
We must have walked past 10 other black and gold GT-Hs in the lot before arriving at ours, the on-site manager standing beside it. Every Shelby receives a special checkout/in to ensure a list of signature parts survives each loan unmolested. The most notable box on the checklist is "traction control off switch — should be inoperable."

Such paranoia on behalf of Hertz is understandable and dates back to 1966, when the now celebrated Shelby GT350H Mustangs entered the rental fleet. Hertz colors (black and gold) date back to the company's birth in the 1920s, although its historical significance seems minor in comparison to that of the car itself. Rental return tales surrounding the GT350H are legendary and range from the remnants of number decals left on doors to cars with cutouts in the floor from recently removed roll cages to those returning with completely different engines. This explains why small details of the '06, like strategically placed engine ties, exist to ward off thievery and make signs of tampering easily detectable.

Four decades later, those stories of abuse have only enhanced the desirability of the GT350H Mustangs. Only 1,000 were built and now each is a highly coveted collector car worth six figures. Whether the market will be as enthusiastic about the 500 GT-H Mustangs Ford and Shelby are piecing together will be fun to watch.

Smoke 'em if you've got 'em
Out of the driveway, stop at the light, push the traction control (TCS) button — nothing. Pull to the side of the road. About 20 seconds and a persuasive pocket knife later we're holding the TCS button and the paper clip-looking mischief-deterrent that was lodged behind it. Reinstall. Push the button — TCS off. This pony is free of its saddle.

From here things get a bit cloudy — Pirelli cloudy. A cacophony of chirps, wails, peels and squeals pours from the back tires, painting black stripes through intersections with ease thanks to an upgraded 3.55 rear axle. The GT-H shares its axle ratio with the manual-trans GT, whereas autos typically sport a 3.31.

Under the hood the Shelby packs a 90mm cold air intake kit, performance oil filter and engine computer recalibration, courtesy of Ford Racing. In fact, with the exception of some bitchin' cosmetic alterations, all parts necessary to build your own GT-H from a stock GT are available online from Ford Racing: Power Upgrade Package ($889), Handling Package ($1,149), rear race brake pads ($410) and a performance X-pipe ($139).

With 325 horsepower and 330 pound-feet of torque, the GT-H boasts a moderate 25-hp, 10-lb-ft improvement over a stock 4.6-liter GT. Stomp the pedal to hear its performance muffler and X-pipe vibrate eardrums emphatically as the car surges from zero to 60 in 5.6 seconds and completes the quarter-mile in 13.9 seconds at 101.1 mph. That's one-tenth faster to 60 mph than our manual-trans long-term Mustang GT and four-tenths ahead of its 14.3-second quarter-mile time.

New shocks, sway bars, shorter springs and strut tower brace deliver a sporty feel, but this new suspension is stupidly stiff and offers a ride unsuitable for public roads. Any significant bump in the road introduces the driver's dome to the car's dome in a painful reminder of the laws of physics. At only 3,000 miles our test car was showing signs of a hard life.

With wheels and tires identical to those of our long-term Mustang, we expected the new suspension to noticeably improve handling numbers on the GT-H. But the Hertz recorded 0.82g around the skid pad and a 64.4-mph speed through the slalom. Like the acceleration runs, we executed each handling test with the car's TCS engaged because that's how the car comes from Hertz. With it off, we expect it would have outmaneuvered our long-term GT, which recorded a 65.2-mph slalom speed with its TCS disengaged.

The addition of racing rear brake pads stops the GT-H from 60 mph in 128 feet, which is only 5 feet shorter than our long-term Mustang. As expected, minor improvements from GT to GT-H yield only minor performance gains — but man, does it sound awesome.

The party's over
Back in front of the Hertz parking lot it takes all of two minutes to reinstall the clip behind the TCS button — we even exchange smiles with a passing Hertz mechanic in the middle of our installation.

Shortly after pulling inside the lot, a manager arrives to inspect the car. The first thing he does is reach inside, turn the key and press the redisabled TCS button. When it passes inspection he turns and says, "That's good. So, how did it run?" The only logical response is to bite our tongue and say, "Just fine."

Edmunds rented this vehicle for the purposes of evaluation.

The GT-H is only offered with an automatic transmission, to help it survive rental-fleet duty.

Shelby takes a 4.6-liter Mustang GT and adds Ford Racing parts, boosting output to 325 hp and 330 lb-ft.

This is what we imagine it would look like if traction control (TCS) could be disabled.

And it can now be driven like a true pony car.

Only 1,000 1966 GT350H Mustangs were built, while Ford and Shelby are piecing together half as many GT-H Mustangs.

The legendary stories of abuse have only enhanced the desirability of the original GT350H Mustangs. Each is now a highly coveted collector car worth six figures.

My first car was a 67 Mustang Coupe, 2nd one was a 67 Cougar XR-7, 3rd one was a 66 Mustang Coupe. Why did I get rid of these cars for ? I know why, because I'm stupid, stupid, stupid.

My next Ford.....

Re: Follow-Up Test: 2006 Ford Mustang Shelby GT-H

But don't let Hertz find out you did this.........

.....or this...... might end up on their "Do Not Rent" list. But you might also end up with a FFW Ultra Stang World Championship.
