When Ford introduced the new 2010 Mustang at the LA Auto Show in November, marketing boss Jim Farley promised the next chapter in the Mustang story would be revealed at the Detroit Auto Show in January. Well that time has arrived and to anyone who has been following the Mustang pattern over the last several years, it should come as no surprise that it's the Shelby GT500. Just like the last iteration, the new GT500 is the most powerful factory production Mustang ever.
Like the more prosaic Mustangs, the GT500 is mechanically an evolution of the older model. Just as Ford used the current-gen Bullitt model as the starting point for the 2010 Mustang GT, the lessons learned from developing the limited edition GT500 KR fed directly into the latest Shelby-badged variant. Output of the supercharged 5.4L V8 has now been cranked up to 540 hp and 510 lb-ft of torque, and the handling is claimed to be better than before. Check out everything that's new on the GT500 after the jump.
Like the last GT500, this one gets more aggressive styling, particularly in the nose, and reprises many of the same detail elements. The horizontally mirrored trapezoidal shape of the grille in the upper and lower front fascia is meant to echo the oval shape of the Shelby Cobras of the '60s. The upper grille is tilted forward at a steeper angle than the GT and the grille surround is separated entirely from the hood. The leading edge of the hood on other Mustangs forms the upper frame of the grille, while the new GT500 has an extra bit of bodywork there.
The hood of the GT500 still has a functional air extractor allowing some of the massive heat generated by the blown V8 to escape. The power dome of the V6 and GT is supplanted by a smoother bulge that now encompasses most of the hood. The driving lamps stay in the lower fascia reprising the last edition and leaving the grille area open for air flow.
Careful observers will note that the snake badge has moved from the right to the left side of the grille (when viewed from the front). This has nothing to do with the blowing of political winds, but is actually functional. Like the GT, the GT500 now has a cold air intake that sits directly behind the snake's former residence.
A revised duck-tail spoiler sits at the back end along the trailing edge of the trunk-lid and incorporates a Gurney flap. The faux diffuser along the bottom of the GT500's rump is now more prominent, although probably not any more functional. Regardless of the diffuser's functionality, the new GT500 does have more down-force thanks to that spoiler and the front splitter. The center of pressure has also been moved further forward, which should help reduce understeer at higher speeds.
The diffuser is flanked by a pair of four-inch diameter tail-pipes that could be used to patch your local water main the next time it bursts. The Shelby badging along the trailing edge of the trunk-lid also now stretches the width of the distance between the tail-lights, just like the original 2005 concept.
Supporting the still excessive mass (we'll get back to that) of the GT500 are new ten-spoke alloy wheels with a slimmer spoke design than before. Coupes and convertibles each get the same design but in different sizes and constructions. The rag-tops get a cast 18-inch version of the wheel, while closed-roof versions get a forged 19-inch construction. The forged version is both stronger and lighter than the smaller wheel compensating for the extra size. The sides of the spokes on the forged wheels are milled, helping to reduce the mass without sacrificing strength.
The leather seats inside the car now have pairs of longitudinal contrasting stripes that echo the stripes stretching the length of the body, as well as alcantara trim on the side bolsters, shift lever, parking braking boots and steering wheel. The traditional white cue-ball shift knob is now also adorned with a pair of black stripes parallel to the shaft of the short throw shifter. All of this is neither here nor there, as none one of these interior niceties makes the GT500 faster, turn better or stop better.
For that we have to look in the engine compartment. The powerplant remains a twin cam 5.4L V8 with a supercharger. New additions to the power plant include knock sensors, the aforementioned cold-air intake and a lower restriction exhaust system. The updates bump output from from 500 hp at 6,000 rpm to 540 hp at 6,200 rpm. Twisting force also goes from 480 lb-ft at 4,500 rpm to 510 lb-ft at the same peak speed.
Unfortunately, one aspect that didn't change is the cast iron engine block. The aluminum block that was used in the Ford GT supercar had a dry sump system that can't be packaged in the Mustang. Thus, the iron block from the F-150 was used with the top end of the GT engine, which pushed the car's weight up over 3,900 lbs. That makes the GT500 both the heaviest and most powerful Mustang.
The top two ratios in the new GT500's gearbox have been made numerically lower to help reduce fuel consumption. As before, getting all the drive torque from the engine to the gears is the job of a dual plate clutch. The clutch plates have been increased in diameter from 215 mm to 250 mm. This allowed Ford to reduce the clutch pedal effort while improving the torque transmission capability.
All that torque flows from the Tremec 6-speed gearbox through a limited slip differential with a 3.55:1 final drive ratio. The 2010 GT500 gets 17% stiffer springs at the front axle and 7% stiffer at the rear axle. The forged alloys on the coupe are wrapped in Goodyear F1 Supercar rubber sized 255/40R19 front and 285/25R19 rear. The Brembo four-pot calipers are retained at the front and the GT500 also get the same standard electronic stability control that lesser Mustangs get for 2010.
Like the GT with the Track Pack, the ESC in the new GT500 always defaults on when the car is started, but can be turned off or put into a Sport mode. In Sport mode, the ESC allows greater amounts of slip before intervening.
The 2010 GT500 now has more power and presumably better handling than before. When we drove the last iterations of the GT500 and Bullitt, the Shelby was undoubtedly faster but the Bullitt was a better all-around car and daily driver. The Bullitt's lighter weight and better balance made it more fun to drive on the street while the blown Mustang was king at the Friday night drag races. Only time will tell if the GT500 can overcome.

Aggressive new exterior design features new functional details, such as the hood extractor to remove heat from the engine and "Gurney Flap" spoiler to tune rear downforce; world-class materials and craftsmanship create the most unique GT500 interior yet
2010 Shelby GT500 will be in dealer showrooms in spring
DEARBORN, Mich., Jan. 1, 2009 – The new 2010 Ford Shelby GT500 delivers the most power and refinement ever for a Ford SVT-tuned performance Mustang – and a few surprises, too.
"The 2010 Shelby GT500 demonstrates Ford's continuing commitment to high-performance vehicles," said Derrick Kuzak, Ford group vice president, Global Product Development. "In addition to the numerous performance and refinement improvements inside and out, the 2010 Shelby GT500 is an estimated 2 miles per gallon more fuel efficient on the highway."
"We're proud of the many enhancements that were developed jointly by the Ford and Shelby Automobiles team last year that we've now incorporated into the new 2010 Shelby GT500," said Carroll Shelby, founder of Shelby Automobiles. "Building on what we learned to create the Shelby GT500KR, this new car offers a great combination of power, handling and braking. It is truly a special car that is a great deal of fun to drive."
Ford's Special Vehicle Team used the gains made on the 40th anniversary edition Shelby GT500KR "King of the Road" Mustangs as the performance starting point and built from there. The design team, with a nod to the original Shelby Cobras from the 1960s, takes those design cues even further with nuanced improvements in both the coupe and convertible, each of which boasts a more-refined interior.
"Working together on the KR, the Ford and Shelby teams developed new systems to continually improve the iconic Mustang," stated Amy Boylan, president of Shelby Automobiles. "Those lessons learned are incorporated into the 2010 Shelby GT500. This approach will help maintain Mustang's leadership position at the front of the pack and make the ownership experience even more enjoyable."
"The muscle car segment is becoming even more competitive," said Jamal Hameedi, chief nameplate engineer for SVT. "We need to uphold the Mustang badge with honor, the Shelby badge with honor and most importantly the Ford badge with honor. The 2010 GT500 is the car that will do all of that."
More horsepower, more refinement, more functionality
The combination of added horsepower, refinement and functionality makes the 2010 Shelby GT500 a unique high-performance car. The 2010 Shelby GT500 delivers more horsepower and more torque than the outgoing model, thanks in part to advancements pioneered on the GT500KR.
The 2010 Shelby GT500 is powered by a supercharged and intercooled 5.4-liter dual overhead cam V-8 engine expected to produce 540 horsepower and 510 foot-pounds of torque. The redline is 6,250 rpm. The car's aluminum power dome hood not only adds to the Shelby's appearance, it helps cool the engine through a hood extractor.
The Shelby's open-element air induction system features a conical air filter instead of a flat-panel closed system to reduce air restriction. This approach allows more air to be pumped through the engine, producing more power and increasing the engine's efficiency.
A cold-air intake feeds the coolest air possible directly into the air box, helping further increase horsepower. The intake necessitated moving the Cobra snake badge to the other side of the grille to enable maximum airflow.
The twin-disc clutch on the six-speed manual transmission has been significantly upgraded, improving drivability and NVH. The discs on the 2010 Shelby GT500 are larger – 250 mm in diameter compared with 215 mm in diameter on the outgoing model – and made of copper and fiberglass to make them more robust.
A unique component of the twin-disc system is the control of the intermediate disc. Rather than floating, it instead has six straps that control the engagement of the clutch, improving drivability.
The 2010 Shelby GT500 offers customers improved straight-line acceleration, plus fuel savings when cruising on the highway in the top gears. Gears 1-4 remain the same, but fifth gear changes from .80 to .74 while sixth gear goes from .63 to .50, meaning that the 2010 Shelby GT500 will turn lower engine RPMs in those gears and deliver improved fuel efficiency. The new final drive ratio, from 3.31 to 3.55, enables the improved acceleration in lower gears while complementing the revised fifth and sixth gear ratios.
The Shelby's distinct sounds will be apparent as always, though with new refinements, thanks to the work of the Noise, Vibration and Harshness (NVH) team. A patented resonator placed between the air filter and engine throttle body helps keep unwanted noise in check.
"You still hear the supercharger but not so that it's intrusive," said Kerry Baldori, chief functional engineer for SVT. "It's the same with the exhaust. You want people to know you're driving something special, but you don't want an exhaust note that overpowers the whole interior.
"We spent a lot of time getting the right sound quality out of the exhaust so you get that nice, crisp Shelby sound outside and a pleasant sound inside the cabin. It's a nice balance; one isn't overpowering the other."
Driving dynamics also are improved, thanks to SVT's signature chassis tuning as well as new 19-inch Goodyear F1 Supercar tires and forged aluminum wheels on the 2010 Shelby GT500 coupe and 18s on the convertible.
Spring and dampers have been optimized for better roll control, giving customers more confidence when braking, accelerating or turning. The new chassis tuning takes its philosophy from the KR program, with a greater emphasis placed on primary body control.
The team also stiffened the steering shaft.
"All our changes were about making the car to respond as fast and as predictable as possible," Hameedi said. "The 2010 Shelby GT500 conveys an athletic, confident feel. The shifter, clutch pedal, brake-pedal efforts and overall steering efforts are easier now. We wanted to make sure we had a nice, crisp short-throw shifter that was easy to go from gear to gear."
The Goodyear F1 Supercar 19-inch tires have been upgraded, too. SVT members developed a "recipe" for the attributes and characteristics they wanted in the tire, which Goodyear's team of engineers, designers and manufacturers brought to life. The result is better grip, better handling and better NVH properties, leading to a better customer experience.
The wheels themselves complement the high-performance nature of the 2010 Shelby GT500. The 19-inch wheels are forged aluminum wheels milled on both sides. The extra machining process creates "blade" spokes with very thin, yet strong, cross-sections. The spokes have a specific curve from the rim to the hub, not only for strength, but also to accentuate the offset and width of the tires.
The 2010 Shelby GT500 features AdvanceTrac, Ford's stability control system with several options for performance. The default "on" mode accommodates every-day driving, and a Sport mode delivers for those wanting to put the Shelby GT500 through its paces on the track. The system also can be turned completely off, although the anti-lock brake system and other active safety systems remain in place. Standard safety equipment includes: dual stage front air bags, side-impact air bags and Ford's Personal Safety System.
Numerous aerodynamic upgrades, including a redesigned splitter, were made to the front end of the 2010 Shelby GT500.
"We worked hard to get as much downforce with as little drag as possible," Baldori said. "We worked to seal off the air that comes in the front so it can't go underneath the car. We spent a lot time sealing components such as the radiator and intercoolor to get rid of all the leak paths.
"The result of this evolution of aerodynamics is we've increased downforce, reduced drag and improved the overall efficiency of the 2010 Shelby GT500."
Directing the air so it's used most efficiently was a painstaking process that ultimately will be rewarding to customers. The design of the front fascia and the car's "flush" hood helps focus air flow. The top grille focuses air into the radiator, with a rubber flap inside the engine compartment helping to seal the system. The lower grille helps cool the intercooler. SVT engineers also went as far to block off specific diamonds in the front of the 2010 Shelby GT500's distinctive grille to help maintain the correct cooling and aerodynamic balance.
A meaner, reskinned snake ready to take to the streets
The 2010 Shelby GT500 is the most-robust design and most-distinctive model of the new 2010 Mustang lineup. "The design we chose was a 'flush' hood where the fascia defines the entire front of the vehicle," Hameedi said. "That's very hard to execute from an engineering standpoint, but it really sets the Shelby off as very, very different from the base Mustang."
"This epitomizes the ultimate Mustang," added George Saridakis, Exterior Design manager of the Mustang and Shelby GT500. "It's all about power and expressing power."
Saridakis said his team took a cue from the Shelby AC Cobra 427 with respect to the front grilles, which are gaping and appear ready to swallow the road.
Another obvious difference for the Shelby is the addition of racing stripes, which also will now be available on the convertible. "Racing stripes made their mark on 1960s-era Ford performance vehicles," Hameedi notes. "That's something we feel is a key part of the Shelby performance DNA – maybe more so than some of our competition."
Rounding out the Shelby's exterior modifications are the unique signature coiled Cobra badges on the front grille and front fenders, a more aggressive front splitter and lower-drag rear spoiler, which added to improved aerodynamic features, round out the exterior modifications. "We wanted the spoiler raked back aggressively to minimize drag, but we also have an integrated Gurney Flap that provides the downforce," Saridakis said.
What's inside counts with the 2010 Shelby GT500
The base 2010 Mustang received a powerful new interior design. For the GT500, the interior design team members challenged themselves to raise the bar even higher to create the ultimate Shelby Mustang interior.
Using genuine materials such as real leather in all seats, real aluminum on the instrument panel and Alcantara inserts on the seats and steering wheel gave the appearance a precisely crafted, jewel-like yet functional feel. "You'll definitely know you're in a Shelby," said Douglas Gaffka, Chief Designer, Shelby GT500.
The genuine aluminum finish panels have a unique-to-GT500 three-dimensional dimpled texture pattern inspired by racing clutch plates, braided hoses and cross-drilled racing brake rotors. The pattern has been painstakingly tuned to compensate for the compound curvature of the instrument panels. In addition, the "GT500" logo has been discretely engraved into the aluminum in front of the passenger as a nod to classic Shelby Mustangs of the 1960s.
This unique aluminum finish panel is fully encapsulated by an exquisite soft seamless TPO (Thermoplastic Olefin) instrument panel with a shape that resonates with Mustang's powerful heritage. The center stack flows into the console and features a sub-flush shifter trim ring, flush cup holder door and lockable console stowage featuring the word "SHELBY" engraved in its Satin Liquid Chrome release button.
All 2010 Mustangs and Shelbys feature bright 360-degree rings surrounding the gauge cluster, uninterrupted by the steering column. These rings will come in chrome for the Mustang and a Satin Liquid Chrome finish for the GT500. This finish is featured throughout the interior. An intricate cobra is etched into the center of the aluminum steering wheel badge. The Shelby Cobra appears at startup on the navigation screen, and the familiar red "SVT" logo utilizes new ambient lighting to illuminate the door scuffplate.
"When customers drive this car, they're not only going to be impressed by the performance and the Shelby heritage, but they're going to see all these carefully designed details and know they've bought a well-crafted car," Saridakis said.
Even the classic white shift knob – an icon of Shelby Mustang DNA from years past – received special attention. First, it had to be the traditional white. It also had to be specific to the Shelby. The answer was to combine the racing-stripes theme with the traditional "H" pattern found on shifters to create a one-of-a-kind knob. Like the exterior, the racing stripes wrap from end to end, encircling the knob.
Wide suite of standard features on the 2010 Shelby GT500
The 2010 Shelby GT500 includes several Ford innovations and industry-exclusive standard features, including:
SYNC: The voice-activated hands-free in-car communication and entertainment system developed by Ford and Microsoft. The system fully integrates most Bluetooth-enabled mobile phones and digital media players, providing customers hands-free cell phone and music selection capabilities – plus new 911 Assist and Vehicle Health Report provided with no monthly fees.
911 Assist: When a phone is properly paired, turned on and connected to SYNC, the system is ready to assist in placing a call directly to a local 911 emergency operator in the event of an air bag-deploying accident. The key advantage of SYNC 911 Assist is speed, as calls are placed directly to local 911 operators.
Vehicle Health Report (VHR): SYNC gathers relevant information from the major vehicle control modules and packages diagnostic data into a usable format in a matter of minutes. That data packet is sent to Ford via an 800-number automatically dialed using the customer's paired and operable mobile phone.
Ambient Lighting System with MyColor™ allows drivers to customize the interior lighting of the vehicle to suit their mood. The enhanced MyColor system features seven base colors – ice blue, purple, blue, orange, red, white and green. Customers also can create 125 custom colors by mixing the red-green-blue palette.
