UPDATE: Check out the first live photos of the 2012 Ford Mustang Boss 302.

The car that Mustang fans have been hoping Ford would build for a very, very long time is finally here: the 2012 Boss 302. Dave Pericak, the Mustang chief engineer says it all.

"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. 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."

Amen, Dave. A true Boss 302 is raw, hardcore and race-inspired, and Ford delivered the goods. The latest special edition Mustang comes with plenty of items that will excite road racing fans - an upgraded clutch, short-throw shifter, adjustable suspension, improved brakes and a more potent version of the 5.0-liter V8 that produces 440 horsepower and 380 lb-ft torque thanks to a new intake and more aggressive camshafts. Ford claims the Boss 302 will be able to break 1.0g and lap a typical road course two seconds faster than the standard Mustang GT. Ford engineers even reportedly benchmarked the BMW M3 when developing the Boss 302, aiming to beat the famous Bavarian coupe around Laguna Seca, which they claim to have achieved.

The exterior is inspired by the original 1969 model with either a black or white roof panel, C-stripe, closed fog lamp openings and a more aggressive front splitter and rear spoiler. Available colors are more eye-catching than the standard choices and include Competition Orange, Performance White, Kona Blue Metallic, Yellow Blaze Tri-Coat Metallic and Race Red.

2010 Boss 302 owners will enjoy a more aural experience from the cockpit thanks to eleven pounds of sound-deadening material removed from the car. The interior also gets a dark metallic finish for the instrument panel, gauge cluster and door panel trim, Alcantara-covered steering wheel and an optional package with Recaro high performance seats.

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.

      I'd take that car in a second. If it can hang with the M3 for what I can pretty much guarantee will be half the price then that truly is an accomplishment. Good job, Ford.
        • 4 Years Ago
        I have a 2009 M3, six speed, but I want the Boss 302, as my second car. Good work!! Ford, for not dumping the v8 I hope you sell all you can make.
      • 4 Years Ago
      Like the Boss 302!

      But them wheels have got to go!

      They needed to retro the Magnum Style wheels and also a Wing Spoiler on the trunk, and mabe white letter tires and it would be a home run!
      • 4 Years Ago
      I can haz?
        • 4 Years Ago
        @Francis - They offer premium Mustang... and I jump in it.
      • 4 Years Ago
      Eh, not impressed.... Just another Mustang edition.
      • 4 Years Ago
      As previous owner of two '70 B302s: I'm pleased the new car seems to have a similar performance envelope as the original Trans Am race cars, which is an amazing feat in itself, and would love to see the two go head-to-head, if only to compare lap times. That said, the 2012 plays upon the looks of the old one, but Larry Shinoda never would have run the stripes across body creases the way Ford does to mimic the '69. So, I could do with less marketing retro hype and more originality. Why market it as the closest thing to a race car unless you judiciously appoint it with carbon fiber, put a roll cage in it and strip the car down to its bare essentials? The bizarre convoluted exhaust just for the sake of sound is not consistent with a pure performance machine. Make the stripes optional and create a true stripped down lightweight at a reasonable cost and it just might create a new legend.
      • 4 Years Ago
      What they did right,

      Those seats
      The retro graphics
      Engine cubic inch displacement instead of stupid liter displacement
      The BOSS 302 was the best Mustang next to the original GT500, it's about time it came back

      What they didn't do so hot,

      Laguna Seca BOSS in black looks like barf
      It needs the driving lights in the grille instead of plastic blanks which look awful

      Even Saleen didn't forget the signature BOSS louvers on their Parnelli-Jones Mustang (the best modern Mustang IMO). Would drive, buggy axle and all.
        • 4 Years Ago
        I think he's coming around...
      • 4 Years Ago
      Do. Want. Now.
      • 4 Years Ago
      make it in calypso coral or alcapulca blue please.
      my love of cars started with the 70 boss 302 and the old SS Cam. i have longed after the boss for about 25 years now, and i still won't be able to afford one. i'm sure this will be priced out of my range (yes, you get more car these days) but even the v6 is over 20k.
      guess i'll just be longing for longer.
        • 4 Years Ago
        You're gonna make me cry man.
        When my Dad was going to university he walked by the same '70 BOSS 302 on the way to class every day. To this day he wishes he could have one. That's not going to happen though with prices for even a good example around 100g.
        I do agree with your paint requests. Some classic grabber colors would be great. Maybe in the next few years they'll style a BOSS after the '70. A shaker would be nice too.
        Hope you get your car some day.

      Now this is what I call a Special Edition Mustang!

      :thumbs up:
      • 4 Years Ago
      Further proof that we're in a second golden age for the Muscle Car. What a great time to live in, and no need for rose-tinted glasses when we look back to the 60's anymore!

      Yes, some beloved brands are gone, but those that remain are better than ever.

      I can't wait for Chevy and Dodge to counter this challenge (Z28, 6.4-liter Hemi Charger Daytona), but for now Ford has made my day.

      Oh, and I'd also love to see the Mach 1 back...
      • 4 Years Ago
      This car looks amazing. This could very well be the first 'Stang to turn my head since 2006 (once it seemed that everybody and their dog owned a fifth gen). I like that Ford is thinking seriously enough about this platform to start making racing variants. Perhaps this bodes well for an eventual non-Shelby with a suspension tuned more for road racing that drag strips?
      • 4 Years Ago
      Sounds impressive. It used to be that if you bought an M3 or Evo or a 911 you could always be confident that you would have better cornering, braking and overall handling to justify paying more money (in the case of the Germans) or making a decidedly different choice (in the case of the Evo) over the typical american pony car. But now that advantage is totally going away because the Mustang is changing the game. I hope these other brands respond accordingly.
        • 4 Years Ago
        German branded seats, where would the other knowledge come from?

        : )
