With a durable, race-proven engine between the shock towers, it was a matter of creating a car worthy of backing up the Boss name. That meant revamping the car from front to back. Improving the aerodynamics, cooling system, exhaust, interior, and differential. Of course, when it comes to a Boss Mustang, the suspension gets the most attention. This led to higher spring rates, larger sway bars, and stiffer bushings. Adding control to that package is a quartet of five-way adjustable dampers.

“The team at Ford wanted to offer fellow Mustang enthusiasts something really special—a beautifully balanced factory-built race car that they could drive on the street,” explains David 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.”

That’s a great sound bite, but in practice the Boss really is a reassuring partner on the road. Prowling the streets of California it proved a well-mannered escort. The suspension was a bit more communicative than a GT’s, but with the dampers dialed back to the number-two setting, it was perfectly pliable. You knew it was tauter, but that’s what a Boss is all about, and I wouldn’t want it any other way.

On the curvy Cali hills, the car simply did what you wanted it to. It was a driver/car union somewhat dampened by traffic and speed limits. The track was what the Boss was born for, so the concept of unleashing it on the legendary Laguna Seca was titillating. After a couple of recon laps with a qualified, skilled driver, it was my turn. Clearly Ford has never seen me drive, but they gave me a helmet and a Boss Mustang and said, “Have fun.” Indeed, on certain days, this job really is the best.

The protocol was to make one warm-up lap, one rager, and one cool-down lap. So it was a tentative start on an unfamiliar track, but as I gained confidence, the Boss became my best friend. I’m no race-car driver, but the car made me feel like one for brief moments. The Boss 302 is such a superb balance of power, handling, and braking that while on track the car’s Pirellis just seemed to dig into the pavement and put the car right where you wanted it. You can feel the car’s center of gravity right in the middle of the car where it’s easy to control. When, not if, I made a false move, the Boss was there to forgive, pat me on the shoulder, and start hauling again.

As I started to pick up the pace, the car was right there with me. Its limits were well beyond mine, especially the brakes. Quite often I was braking before I needed to, as I wasn’t used to brakes that good. Not only does the car have the familiar Brembo calipers, but low-expansion brake lines and a track friendly pad material. These things flat out worked, and unlike many press drives, where cars fell by the wayside for maintenance, the Boss only needed to stop for fuel and it was ready for more abuse.

It turns out that proving a combination on the track is exactly the proper way to prove out a track-capable production car. In fact, while discussing the car in the pits it was posed to me that this car is most reminiscent of the fabled Cobra R. The last R-model has long been one of my favorite Mustangs for its ripping, high-rpm power and made-for-the track persona. However, the ’12 Boss 302 is a much better car in nearly all respects. It revs higher, goes faster, rides better, and it still has a full interior and a radio—and that’s just the base Boss with the street tuning.

Looks like it’s time to rearrange that list.
