MONTEREY, Calif., Aug. 13, 2010 – Ford gave the green light only once before: In 1968, management approved a special Mustang – a car that sacrificed nothing in its quest to be the best all-around road-going performance machine ever created by Ford Motor Company. That car became the 1969 Mustang Boss 302, and it remains one of the world's most sought-after examples of American performance.

Forty-two years later, Ford has given the green light again.

The team of Ford engineers, designers and stylists – all Mustang enthusiasts to the core – that created the groundbreaking 2011 Mustang GT has distilled a new model to its purest form, strengthening, lightening and refining each system to create a race car with a license plate. Its name: the 2012 Mustang Boss 302.

"The decision to build a modern Boss was not entered into lightly," said Derrick Kuzak, group vice president, Global Product Development. "The entire team at Ford felt the time was right and with the right ingredients, the world-class 2011 Mustang could support a successful, race-bred, worthy successor to the original Boss 302. For us that meant a production Mustang that could top one of the world's best – the 2010 BMW M3 – in lap times at Laguna Seca. We met our expectations."

To celebrate the racing heritage of the new Mustang Boss 302, Ford will also offer a limited number of Boss 302 Laguna Seca models, named for the track where Parnelli Jones won the 1970 Trans-Am season opener in a Boss 302. Aimed at racers more interested in on-track performance than creature comforts, the Boss 302 Laguna Seca has increased body stiffness, a firmer chassis set-up and an aerodynamics package carried over almost in its entirety from the Ford Racing Boss 302R.

Philosophy and powertrain

"The new Boss 302 completely redefines Mustang capability," said Mark Fields, Ford president of The Americas. "That the Mustang team was able to take the current Mustang GT – already a world-class performance car – and refine it further for peak track performance shows the commitment Ford has to this car and its legions of fans."

Driving the 2012 Mustang Boss 302 was intended from the outset to be a visceral experience, packed with raw, unbridled performance across the spectrum: Acceleration, handling, braking, and top speed are all equally matched for perfect balance on a car operating within the framework of legally defined safety, noise and emissions regulations.

"The team at Ford wanted to offer their fellow Mustang enthusiasts something really special – a beautifully balanced factory-built race car that they could drive on the street," explains Dave Pericak, Mustang chief engineer. "The Boss 302 isn't something a Mustang GT owner can buy all the parts for out of a catalog or that a tuner can get by adding a chip. This is a front-to-back re-engineered Mustang with every system designed to make a good driver great and a great driver even better."

Led by Mike Harrison, the V8 engine team approached Boss from the top down: With 412 horsepower from 5.0 liters, the 2011 GT engine was already an incredible performer. But to achieve the high-rpm horsepower that would make the engine competitive on the track, a new intake was essential. The resulting runners-in-the-box plenum/velocity stack combination the engine team developed was impressive enough that it got the green light after one short drive.

Helping the intake build power, revised camshafts using a more aggressive grind are actuated with the same twin independent variable camshaft timing (Ti-VCT) mechanism used on the Mustang GT. More aggressive control calibration yields 440 horsepower and 380 lb.-ft. of torque, while still offering a smooth idle and low-end torque for comfortable around-town driving.

A race-inspired clutch with upgraded friction materials transmits power, while a short-throw, close-ratio six-speed manual transmission handles gear change duties.

Power is delivered to a 3.73 ratio rear axle using carbon fiber plates in the limited-slip differential to improve torque handling and longevity. For those who want even more precise control over power delivery, a torque-sensing (Torsen) limited-slip differential is an available option coupled with Recaro front seats.

Sounds like the Boss

While the powertrain team defined output targets that would yield an ideal balance with the chassis, another team made sure the car made the kind of sounds owners and enthusiasts would expect from a Mustang Boss.

Up front, a Boss-specific intake system is tuned to feed the engine with minimum restrictions. A retuned induction sound tube provides concrete aural evidence of what's occurring under the hood. And, in the Boss exhaust system engineers really had some fun.

"With an exhaust system, we have to consider three constraints: legal noise restrictions; backpressure, which can rob power; and ground clearance," explains Shawn Carney, Mustang NVH engineer. "Since the 2011 Mustang GT exhaust is already so free-flowing – it came in way under our backpressure targets – we already had excellent performance; we were able to tune the exhaust system for a unique sound. Combined with the rush of the intake, the exhaust system really envelops the driver in V8 sound."

Every Boss features a unique quad exhaust system: Two outlets exit in the rear similar to a standard Mustang GT. The other two outlets exit to either side of the exhaust crossover, sending exhaust through a set of metal discs that act as tuning elements before the pipes terminate just ahead of the rear wheel opening. Visually subtle, the side pipes flow very little exhaust but a lot of exhaust sound, providing a sonic experience unlike any other Mustang – and giving home tuners an additional avenue for modification.

"We added the attenuation discs to meet legal regulations, but we knew buyers might operate these cars in situations where noise regulations weren't an issue," Carney said. "The disc is removable and includes a spacer plate sized to match aftermarket exhaust dump valves. If an owner wants to add a set of electric valves, they just undo two bolts on either side; the disc and spacer slide out and the valve will slide right in. And the side pipes are tuned so that drivers can run wide-open and the sound levels are comfortable – very aggressive but livable for an all-day track outing."

Carney further explains the thinking behind the unusual step of an OEM easing aftermarket component installation. "We're Ford engineers, but we're also enthusiasts," he says. "We understand owner mods are part of the Mustang experience, so we try to help where we can."

Suspension and steering

In keeping with the Boss mandate to provide the best-handling Mustang ever, the already strong Mustang GT suspension system has been further refined. Higher-rate coil springs on all four corners, stiffer suspension bushings and a larger-diameter rear stabilizer bar all contribute to the road racing mission, and Boss models are lowered by 11 millimeters at the front and 1 millimeter at the rear versus the Mustang GT. The real key to handling, though, is in the adjustable shocks and struts, standard on all Boss Mustang models.

"We've given drivers five settings for their shocks," says Brent Clark, supervisor of the Mustang vehicle dynamics team. "One is the softest, two is the factory setting and five is the firmest, and we've provided a wide range of adjustment. A customer can drive to the track on setting two, crank it up to five for improved response on the track, then dial down to one for a more relaxed ride home. What's unique is that drivers will find – thanks to the way the suspension works as a complete system – the softest setting isn't too loose and the firmest setting isn't too controlled; each step just provides additional levels of control."

Also unique is the method of shock adjustment. Ditching the weight and complexity of electronic wizardry, the Mustang team opted for traditional race-style hands-on adjustability – similar to the Gabriel shocks available on the original Boss 302.

"The shock adjustment is right at the top of the shock tower, built into the rod and easily accessible from under the hood or inside the trunk," says Clark. "You just take a small flat-head screwdriver, turn the adjustment screw between one and five, and head back out onto the track."

To complement the suspension, the speed-sensitive electronic steering system has been retuned to maximize feedback and road feel to the driver. The driver is also given the option of fine-tuning the steering feel to his liking by selecting one of three settings through the instrument cluster menu: Comfort, normal and sport modes help offer track-tuned steering when desired without sacrificing low-speed maneuverability in parking situations and everyday commuting.

Similarly, Boss receives unique traction control system (TCS) and electronic stability control (ESC) settings to help drivers achieve maximum performance whether on the street or at the track. Both systems can be completely disabled in controlled track situations where maximum driver skill is utilized, or fully engaged for maximum safety during normal driving or in less-than-ideal traction conditions. Intermediate sport mode allows drivers to push their cars hard at the track without completely disabling the safety systems, permitting more aggressive driving before the TCS and ESC systems intervene.

Brakes, wheels and tires

Working in concert with the suspension upgrades, Boss 302 receives unique, lightweight 19-inch black alloy racing wheels in staggered widths: 9 inches in front, 9.5 inches in the rear. The Pirelli PZero summer tires are sized specifically for each end of the vehicle, with the front wheels receiving 255/40ZR-19 tires while the rear stays planted thanks to 285/35ZR-19 rubber.

The combined suspension and tire package allows Boss to achieve a top speed of 155 mph and become the first non-SVT Mustang ever to achieve more than 1.0 g of lateral acceleration.

Boss braking is also up to the challenge, using Brembo four-piston front calipers acting on 14-inch vented rotors up front. In the back, standard Mustang GT brakes are upgraded with a Boss-specific high-performance pad compound. Combined with vented brake shields and unique Anti-Lock Brake System (ABS) tuning, Boss drivers get maximum control and rapid, repeatable fade-free stops in road and race situations alike.

The Mustang team spent considerable time ensuring the brake pedal feel met the expectations of performance drivers. Boss receives unique low-compressibility brake lines that expand up to 30 percent less than traditional flexible brake lines, allowing maximum fluid pressure to reach the calipers in the least amount of time, giving the driver a sensation of being connected directly to the brake pads.

"This car is wicked fast, so we put a lot of emphasis on giving it comparable stopping power," says Clark. "We started with a race-proven brake system and tuned it specifically for the characteristics of the Boss 302 and its mission. They're the best brakes ever installed on a Mustang, and they give consistent, repeatable braking performance on the street and the track."

As a result 60-0 stopping distances for the Boss are improved by approximately three feet versus the Mustang GT with available brake package; combined with suspension and engine improvements, Boss is expected to show approximately a two-second lap time improvement over the GT on a typical road race course. But the numbers tell only part of the story.

"We achieved measurable improvements over GT, which was already one of the best-braking cars we've ever designed," explains Clark, "but what's harder to quantify is how good these brakes feel to a driver in a race situation. Like everything on this car, the brakes are more than the sum of their parts: They're tuned from pad to pedal to work perfectly as a system, and the difference is dramatic."

Exterior and interior design

Changes to the Mustang Boss exterior are subtle but unmistakable. True to its race-bred heritage, every component that could potentially aid aerodynamics or engine/brake performance was examined to make the vehicle more competitive, while chief designer Darrell Behmer refined the styling to evoke the 1969 Boss in a contemporary way.

"We approached this as curators of a legend," explains Behmer. "We've taken design cues from the '69 Boss street car and the menacing Bud Moore/Parnelli Jones race cars and carefully updated them to give the 2012 the proper bad-boy attitude that is unmistakably a Boss Mustang."

To set Boss apart, each car will have either a black or white roof panel, coordinated to the color of the side C-stripe. Available exterior colors are Competition Orange, Performance White, Kona Blue Metallic, Yellow Blaze Tri-Coat Metallic and Race Red.

Up front, a unique fascia and grille are highlighted by the blocked-off fog lamp openings and aggressive lower splitter, a version of the design used – and proven – on the Boss 302R race car. The front splitter is designed to function at high speeds by efficiently managing the air under and around the car. It helps to reduce underbody drag and front end lift while more effectively forcing air through the Boss-specific cooling system. At the rear of the car, the spoiler was chosen to complement the front aero treatment and minimize overall drag.

"What we were after on Boss was reduced overall lift with improved balance," says Pericak. "We needed to keep the car glued to the street or the track at high speeds without increasing drag or affecting top speed and fuel usage. The end result is an aero package that uses front, rear and underbody treatments not for show, but for effect – the balance and stability of this car all the way to its 155-mph top speed is just outstanding."

Inside, a unique Boss steering wheel covered completely in Alcantara suede complements the standard seats, which are trimmed in cloth with a suede-like center insert to firmly hold occupants in place. Boss customers who want the ultimate seating experience can select a package that includes Recaro buckets, designed by Ford SVT in cooperation with Recaro for high performance Mustang models, and shared between the Boss and GT500.

A dark metallic instrument panel finish, gauge cluster and door panel trim also differentiate Boss from the standard Mustang, while a black pool-cue shifter ball and "Powered by Ford" door sill plates further remind customers they're in a special car.

The Boss interior gets an aural kick thanks to what's been removed. Eleven pounds of sound-deadening material have been eliminated to let occupants further enjoy the intake, engine and exhaust note.

"Boss is a hallowed word around here, and we couldn't put that name on a new Mustang until we were sure everything was in place to make this car a worthy successor," explains Pericak "We were either going to do it right or not do it at all – no one on the team was going to let Boss become a sticker and wheel package.

New Design, More Technology for Ford Mustang

• New exterior design with more prominent grille, new hood and new LED signature lighting give the latest Mustang a high-tech look

• Drivers of automatic-equipped Mustangs will be able to shift their own gears with new SelectShift Automatic™ transmission, now a standard feature

• Industry-first technology allows drivers to monitor their own acceleration, g force and braking on the track with new 4.2-inch LCD screen showing Track Apps

LOS ANGELES, Nov. 15, 2011 – Ford Mustang – the icon of American performance and style – gets even more street swagger with a new design and a list of smart features that signal even more technology in the popular pony car.

"The new Mustang is the perfect example of continuing to build on excellence. It takes the greatness of the 5.0-liter and V6 and pushes the refinement to the next level," said Dave Pericak, Mustang chief engineer. "The car has been spot-on functionally and now we're adding more features and technology to further improve the driver's experience."

More aggressive design

The new model Mustang, which goes on sale in spring 2012, offers a more aggressive design with a significantly more prominent grille. A more powerful splitter adds to that appearance. Functional heat extractors on the hood of the GT were specifically placed and designed to help move hot air out of the engine compartment and cool the engine.

"We are delivering a more distinctive and emotional design presence that celebrates the total performance of Mustang," said Darrell Behmer, Mustang chief designer. "This latest Mustang design is very respectful of its heritage while continuing to look forward with a more powerful and modern look."

Rocker panels running along the car are now body-color, making for a more premium appearance. The rear has been updated with a high-gloss black panel that connects the taillamps. Keeping the sequential turn signal Mustang is known for, the taillamps also deliver a smoked appearance that matches the more purposeful look up front.

Also new for Mustang design are standard high-intensity discharge (HID) headlamps on both V6 and GT cars. Signature lighting plays into the technology upgrades for 2013 as well, with two individual light-emitting diode (LED) bars accentuating the front headlamps and three LED ropes forming the iconic three-bar rear lights.

The new Mustang offers a revamped wheel lineup, ranging from the standard 17-inch wheels for V6 all the way up to 19-inch optional wheels on the GT and V6 Performance Package. With updated designs, the wheels also offer new finishes and touches for a more powerful appearance.

There are two different finishes on the 17-inch wheel – machined-aluminum and painted. Three optional V6 wheels include an 18-inch polished aluminum set, an updated 18-inch painted aluminum and a 19-inch painted wheel design, with a new theme for the V6 Performance Package.

The standard 18-inch painted aluminum wheel on both GT and premium GT is an evolution of the five-spoke design. The 19-inch optional GT wheel comes with a gloss-black finish with machined face for a more sinister look.

The new car also offers mirrors with pony projection light, which casts the image of Mustang's famous pony emblem on the ground when the unlock button is activated. New colors – Deep Impact Blue and Gotta Have It Green – join the existing sporty colors for 2013.

Also new on V6 and GT are optional leather-trimmed or cloth Recaro® seats that are currently available on the Shelby GT500 and Boss 302. Designed to enhance the high-performance driving experience, lateral bolsters in the cushion and seatback are used to ensure drivers have the support needed on the track during hard cornering and to deliver a comfortable ride.

The seats also come complete with integrated head restraints with ample room for drivers and passengers wearing helmets when at the track. Openings on the seatback are included for customers looking to create performance setups for their car on track days. The Recaro seats are the result of a global team effort led by SVT along with the Mustang engineering group in North America, Team RS in Europe and Recaro.

New driving technologies

The 2013 Mustang with 5.0-liter engine will now deliver 420 horsepower. Based on learnings from developing the high-output 444-horsepower Mustang Boss 302, the team was able to adapt several of the designs to the 5.0-liter.

The new Mustang can be specified with a six-speed SelectShift Automatic™ transmission. This advanced control strategy offers the driver a choice between fully automatic operation and manual control. The system is controlled with a selector button on the side of the shifter. The shifter has been upgraded for 2013 with more modern style and improved accessibility.

"This lets owners take an automatic out on a track day or whenever they want to drive sportier, and lets them have the convenience of switching to manual control," said Tom Barnes, Mustang vehicle engineering manager. "It's a significant improvement to our powertrain offerings that lets the driver take control."

This capability makes the Mustang experience sporty yet smooth. Unlike some competitors' transmissions, SelectShift won't second-guess the driver with an override shift. With SelectShift, manual control is truly manually controlled.

A new option, the GT Track Package, debuts for 2013 for customers who want to push their Mustang even further at the track. Available only on manual GT Mustangs with a 3.73 axle, the package gives track enthusiasts an engine cooler, upgraded radiator, performance friction brake pads and the same Torsen® differential that's on Mustang Boss 302. The package includes everything in the current Brembo™ Brake Package, with 14-inch vented front discs, unique 19-inch alloy wheels and summer performance tires.

Other optional package updates for 2013 include offering the Brembo Brake Package on both manual and automatic transmissions on Mustang GT. The V6 Performance Package is now available on automatic Mustangs for the first time.

Hill start assist makes its debut on manually equipped Mustangs. This feature helps keep the car from rolling backward, making it easier to pull away when on a slope or hill. With the brake pedal pressed, if sensors detect the car is on a slope, the system is automatically activated. Brake pressure is held in the braking system and the car remains stationary on the slope for up to two seconds after the driver releases the brake pedal.

A new 4.2-inch LCD productivity screen that lets customers access information related to fuel economy and vehicle performance also makes its debut on Mustang. The screen is navigated through a five-way control button located on the steering wheel and offers Track Apps, which delivers performance metrics for drivers right from the factory. The app measures g forces, shows acceleration times in quarter-mile and 0-60 increments, and displays braking times, complete with automatic and countdown starts.

The 2013 Mustang also offers customers two new audio systems for even better sound quality for incredible clarity and crispness. The optional Shaker™ system comes with eight speakers and pumps out 370 watts of power. The upgraded Shaker Pro offers nine speakers and delivers 550 watts of power.

The 2013 Ford Mustang will be built at AutoAlliance International Plant in Flat Rock, Mich

Ford Mustang Boss 302: Back with More for 2013, Paying Homage to a '70s Legend

• 2013 Ford Mustang Boss 302 builds on the heritage of the 1970 Boss 302 with new, reflective hockey stick graphics package – first modern application on a production car

• Also new for 2013 is heritage-inspired School Bus Yellow paint and Sterling Gray accents on Boss Laguna Seca, which delivers race-ready suspension, aerodynamic details and removed rear seat

• Ford SYNC® connectivity system becomes a standard Boss feature for 2013, adding to a specially tuned engine, quad exhaust, brakes, suspension and design that optimize weight, aerodynamics and track performance

LOS ANGELES, Nov. 15, 2011 – The Ford Mustang Boss 302 is all about performance, and a nod to heritage comes standard with new paint options and design details for 2013.

A new hockey stick graphic featuring reflective stripes is added to the new Boss, calling back the 1970 Boss 302. 2013 Boss 302 and Boss Laguna Seca models feature new School Bus Yellow paint, honoring Parnelli Jones' 1970 Trans-Am championship car prepared by Bud Moore.

"Everything we did for 2013 is consistent with and links directly back to our 1970 heritage. The reflective stripes and hockey stick graphic in particular mean something to Mustang enthusiasts," said Dave Pericak, Mustang chief engineer. "Last year, we proved the car had what it takes to perform, and this year we focused on enhancing its eye-catching looks and celebrating its history."

The reflective stripes on Boss come to life when lights hit them, similar to how they did in 1970 on the Mustang Boss 302. The new stripe follows the classic hockey stick motif by going over the fender and extending down the body panel.

Boss Laguna Seca has new Sterling Gray accents and will be available in vintage School Bus Yellow and black paint offerings, complemented by hockey stick stripes and gray interior rear cross-brace. Gray also sets off the front grille, mirror caps and rear pedestal spoiler, while Laguna Seca rear badging and unique two-tone gray and silver wheels round out the exterior accents. Unlike the previous model, the roof will not feature colored accents.

Similar to the redesigned base Mustang lineup, the front end offers a more powerful design with a more prominent grille. A more powerful splitter and functional hood extractors add to that look. Boss Mustang has new signature lighting, with standard HID headlamps and LED-surround taillamps.

The 2013 Boss also offers a unique functional design feature in the grille with removable covers where fog lamps would be. For improved cooling on track days, the covers can be easily removed with a screwdriver.

Additionally, the rear end features a high-gloss black panel that connects the taillamps. The taillamps deliver a smoked appearance that matches up with the sinister look up front.

The new Mustang Boss includes Ford SYNC®, the voice-activated in-car connectivity system, as a standard feature. With the base SYNC package, customers enjoy the core hands-free features and services that have quickly established SYNC as a must-have technology, with more than 76 percent of current SYNC users saying they would recommend the system to others.

Some features of SYNC include:

• Hands-free, voice-activated calling via a Bluetooth®-connected mobile phone and control of a USB-connected digital music player
• 911 Assist™, the automated emergency calling service that is free for the life of the vehicle
• Vehicle Health Report, the on-demand diagnostic and maintenance information service

Revved up and ready

The powerful Boss engine yields 444 horsepower and 380 lb.-ft. of torque, while still offering a smooth idle and low-end torque for comfortable around-town driving. A race-inspired clutch with upgraded friction materials transmits power, while a short-throw, close-ratio six-speed manual handles gear change duties.

Power is delivered to a 3.73-ratio rear axle using carbon fiber plates in the limited-slip differential to improve handling and longevity. For those who want even more precise control over power delivery, a torque-sensing (Torsen) limited-slip differential is available, coupled with Recaro® front seats.

In keeping with the Boss mandate to provide the best-handling Mustang ever, the already strong Mustang GT suspension system has been further refined. Higher-rate coil springs on all four corners, stiffer suspension bushings and a larger-diameter rear stabilizer bar all contribute to the road racing mission, and Boss models are lowered by 11 millimeters in front and 1 millimeter at the rear versus Mustang GT. But the real key to handling is in the adjustable shocks and struts, standard on all Boss Mustangs.

Working in concert with the suspension upgrades, Boss 302 receives unique, lightweight 19-inch black alloy racing wheels in staggered widths: 9 inches in front, 9.5 inches in the rear. The Pirelli PZero summer tires are sized specifically for each end of the car, with the front wheels receiving 255/40ZR-19 tires while the rear stays planted thanks to 285/35ZR-19 rubber.

Boss braking is also up to the challenge, using Brembo four-piston calipers acting on 14-inch vented rotors up front. In back, standard Mustang GT brakes are upgraded with a Boss-specific high-performance pad compound. The combination of vented brake shields and unique Anti-Lock Brake System (ABS) tuning gives Boss drivers maximum control and rapid, repeatable fade-free stops in road and race situations alike.

2013 Ford Shelby GT500 Debuts as Most Powerful Production V8 in the World with 650 Horsepower, Top Speed of 200+ MPH

• New Ford Shelby GT500 is powered by an aluminum 5.8-liter supercharged V8 producing 650 horsepower and 600 lb.-ft. of torque, making it the most powerful production V8 engine in the world

• Nearly every vehicle system has been optimized including powertrain, brakes, gearing and suspension

• New Shelby GT500 sets a performance-driven design standard with new downforce- generating front grilles, aggressive splitter, new quad exhaust system and two new forged-aluminum wheels

• Also new for 2013 is an optional Performance Package with SVT-designed Bilstein electronic adjustable dampers and a Torsen limited-slip differential. The offering can be coupled with a Track Package for all-out racetrack performance

LOS ANGELES, Nov. 15, 2011 – The ultimate Ford Mustang – Shelby GT500 – raises the bar high on performance with the introduction of the new 2013 model that goes on sale next year delivering 650 horsepower and a top speed of more than 200 mph.

"SVT keeps the Shelby GT500 on the cutting edge of technology and takes muscle car performance to new heights," said Jost Capito, director of Global Performance Vehicles and Motorsport Business Development. "We encapsulated every aspect of performance in this car – whether it's 0-60, top speed, racetrack or quarter-mile times. Beyond that, the daily driver also will find this car perfectly fits his or her needs."

The 5.8-liter V8 aluminum-block engine produces 650 horsepower and 600 lb.-ft. of torque, making it the most powerful production V8 in the world. The 3,850-pound car also stays exempt from the gas-guzzler tax.

Nearly every part of the powertrain has been optimized for producing the additional horsepower, including a new supercharger, new cross-drilled block and heads, updated camshaft profiles, a new carbon fiber driveshaft and upgraded clutch, transmission and axle.

A larger, more-efficient supercharger flowing more air through the engine is key to helping produce the massive 650 horsepower. The new TVS series 2300 creates 2.3 liters of displacement and is a unique design to the 5.8-liter engine.

The entire cooling system has been significantly updated on the new 5.8-liter engine. It now includes a larger cooling fan, fan shroud with high-speed pressure-relief doors, a more efficient charge air cooler, a higher-flow intercooler pump and an intercooler heat exchanger with volume increased 36 percent.

Revised gearing

Nearly every gear on the 2013 Ford Shelby GT500 was revised to manage the torque and use more of the power in a way that makes it more driver-friendly. Engineers considered more than 35 gearing combinations, finally deciding on one that delivers less torque all the way through the wheels to the ground and still enables the car to achieve fuel economy targets.

A key piece of the driveline, the six-speed manual transmission, offers upgraded gears, bearings and housing so it can properly manage the torque. The final drive ratio is now 3.31:1 for optimized overall vehicle gearing to complement the massive torque. Every gear besides fourth was optimized for competing performance metrics. The clutch has increased torque and rpm capacity and uses a dual-disc design.

"It might just seem like we're putting a bigger engine into the car. But it's been a balanced approach through and through," said Jamal Hameedi, SVT chief engineer. "We've completely redone the car to be even more sophisticated in terms of handling and control than the prior model."

Other keys for improved traction management include:

• Torsen limited-slip differential: When customers order the optional Performance Package, they will get a Torsen limited-slip differential that helps the rear suspension deliver maximum torque and traction better and longer under track conditions

• Launch control: A new launch control system lets drivers set the desired launch rpm depending on tire temperature, street surface or other conditions. Unique to SVT's launch control is that it is integrated with both the engine control and traction control

• Brembo braking system: A new Brembo brake system offers drivers enhanced stopping power to help keep their car under control, both on the road and the track. New six-piston calipers in front along with larger front and rear rotors help improve brake fade. New brake pads that are more aggressive also help the car achieve high deceleration and further robustness for more driver confidence

Aero advancements

Significant aerodynamic work was done on the new Shelby GT500 to ensure the car has proper downforce for optimum performance at all speeds. Engineers were able to determine how to harness the air that was moving around and through the car to improve the cooling system, maximize downforce and minimize drag.

The front fascia and splitters were modified to handle the extreme loads at 200 mph, resulting in a car that tracks more securely and feels more planted to the road at higher speeds. It offers 33 percent more effective aero loading at 160 mph compared to the 2011 model.

Superior ride

The new Shelby GT500's driving dynamics have been improved, now working in concert with all the new content on the car.

Handling, all AdvanceTrac settings and steering assist levels within selectable steering have been tuned to account for the updated content. The previously available unique traction control system and electronic stability control settings help drivers achieve maximum performance on both the street and the track.

Both systems can be completely disabled in controlled track situations where maximum driver skill is utilized, or fully engaged for maximum safety during normal driving or in less-than-ideal traction conditions. Intermediate sport mode allows drivers to push their cars hard at the track without completely disabling the safety systems, permitting more aggressive driving before the traction control and electronic stability control intervene.

"We took a completely different approach with this car so drivers can choose their settings instead of a computer making the selection," Hameedi said. "Nearly every system the driver interacts with can be tailored to his or her situation including the Bilstein electronic adjustable suspension, launch control, AdvanceTrac and steering assist levels."

The 2013 Shelby GT500 offers two new sets of forged-aluminum wheels including a unique wheel for cars with the optional packages. The 19-inch front and 20-inch rear wheels are coupled with Goodyear Eagle® F1 SuperCar G: 2 tires on all vehicle configurations.

Taking it one step further

Sometimes Ford Shelby GT500 customers want to enjoy their car on surface streets. Other times they just want to let loose on the track. Two new optional packages on the 2013 model give them the choice.

Available as part of the optional Performance Package, SVT-designed Bilstein electronic adjustable dampers are accessed on the dash with a simple push of a button. Normal mode gives customers a more comfortable ride over road irregularities. Sport mode is all about performance, delivering improved response time on the track and less body roll while cornering and pitch under braking. The Torsen limited-slip differential also comes with the Performance Package.

"The adjustable shocks let us develop our car on the track without any compromise," said Kerry Baldori, Ford SVT Global Performance Vehicles chief engineer. "Before, we had to tune the car with street implications in mind. Now we can go as extreme as we want on the track setting and still offer the customer a comfortable ride on the road."

Enthusiasts can upgrade their Performance Package with an additional Track Package for all-out performance. The option comes with an external engine oil cooler, rear differential cooler and transmission cooler for further durability. The coolers play an essential role in preventing crucial components from overheating under high-speed conditions.
The 2013 Ford Shelby GT500 will be built at AutoAlliance International Plant in Flat Rock, Mich
