Today might well be one of the newest historic milestones in Mustang history. This is the day Ford has revealed the 2012 Mustang BOSS 302. Ford says the new limited production 2012 Mustang BOSS 302 set to become the quickest, best-handling straight-production Mustang ever offered.

They have upgraded nearly every vehicle system; engine output, brakes, suspension, interior and exterior all to optimize weight, aerodynamics and track performance. And the say that this comprehensive new package is available only through the factory. You will not be able to order it out of a catalog or achieve it through tuning or aftermarket parts.

The 2012 Mustang BOSS 302 will also comes with an additional tier, the limited-production track-oriented BOSS 302 Laguna Seca model. Akin to the SVT Performance Package on the GT-500, the Laguna Seca package expands on BOSS racing aspirations, deleting rear seat and adding race-ready suspension and aerodynamic treatments.

Starting with the power plant that gives the car its name, they took the all new 5.0 liter V8 from the 2011 Mustang GT and stepped it up a few notches. 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.

While the power train 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.

Side pipes! 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.”

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.

Working in concert with the suspension upgrades, BOSS302 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.

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.”
