Ford Mustang V (facelift 2009) Boss 302 5.0 V8 (444 Hp)

The Ford Mustang V (facelift 2009) Boss 302 5.0 V8 (444 Hp) represents a highly specialized and revered variant of the fifth-generation Ford Mustang, an icon of American muscle and performance. Introduced for the 2011 and 2012 model years, this limited-production model paid homage to the legendary 1969-1970 Boss 302 Mustang, a car built to dominate SCCA Trans-Am racing. Ford engineers meticulously re-engineered the standard Mustang GT to create a street-legal track weapon, blending classic American styling with modern performance technology. The Boss 302 was designed to bridge the gap between the standard Mustang GT and the more extreme Shelby GT500, offering a naturally aspirated, high-revving alternative focused on handling prowess and driver engagement rather than outright horsepower. It quickly carved out its niche as a highly desirable collector’s item and a formidable competitor on both the street and the racetrack.

Engine and Performance of the Ford Mustang Boss 302

At the heart of the Ford Mustang V (facelift 2009) Boss 302 5.0 V8 (444 Hp) lies a specially modified version of Ford’s 5.0-liter “Coyote” V8 engine. While the standard Mustang GT of the era produced 412 horsepower, the Boss 302’s engine was significantly upgraded to deliver 444 horsepower at a soaring 7400 rpm and 380 lb-ft of torque at 4500 rpm. This power increase was achieved through a series of meticulous enhancements, including CNC ported cylinder heads, revised camshafts with more aggressive lift and duration, a high-flow “runners-in-box” composite intake manifold, and a unique engine calibration. These modifications pushed the redline to an exhilarating 7500 rpm, giving the Boss 302 a distinct, high-revving character not typically associated with American V8s of the era.

Power is channeled to the rear wheels through a robust six-speed manual transmission, providing a direct and engaging driving experience. The powertrain architecture is a classic front-engine, rear-wheel-drive setup, fundamental to the Mustang’s identity. The naturally aspirated engine boasts a high 11:1 compression ratio and utilizes a multi-port manifold injection system, complemented by a sophisticated DOHC (Dual Overhead Camshaft) valvetrain with Ti-VCT (Twin Independent Variable Cam Timing) for optimal power delivery across the rev range. This combination resulted in a highly responsive and potent engine, capable of delivering exhilarating acceleration and a visceral soundtrack, further amplified by a unique quad-exhaust system featuring side-exit pipes that could be uncorked for track use. The weight-to-power ratio stands at an impressive 3.7 kg/Hp (8.16 lbs/Hp), translating to 269.6 Hp per tonne (244.5 Hp per US ton), underscoring its performance credentials.

Design and Features

The design of the Ford Mustang V (facelift 2009) Boss 302 is a masterful blend of retro-inspired aesthetics and contemporary performance cues. Based on the facelifted S197 generation Mustang coupe, it retains the iconic long hood, short deck proportions. However, the Boss 302 distinguishes itself with a unique front fascia featuring a more aggressive splitter, a blocked-off grille with an offset pony badge, and a distinct front air dam. Bold C-stripe graphics, reminiscent of the original Boss 302, adorn the sides, while a prominent rear spoiler and a unique rear diffuser complete the performance-oriented exterior. The car rides on specific 19-inch alloy wheels, 9J wide at the front and 9.5J at the rear, wrapped in high-performance Pirelli PZero tires (255/40 R19 front, 285/35 R19 rear) for maximum grip.

Beyond aesthetics, the Boss 302 received significant chassis enhancements. The suspension was thoroughly revised with stiffer springs, larger diameter anti-roll bars, and manually adjustable dampers (requiring a flat-head screwdriver to adjust on the car). The steering system, an electric power steering unit, was recalibrated for improved feel and precision. Braking performance was drastically improved with 14-inch (355mm) ventilated discs up front and 11.8-inch (300mm) ventilated discs at the rear, both equipped with ABS. The interior featured unique Boss 302 badging, a suede-wrapped steering wheel, and an optional set of Recaro sport seats, providing superior lateral support for spirited driving. A particularly unique feature was the “Trunk Key” which, when used, unlocked a more aggressive engine calibration, increasing throttle response and modifying idle characteristics for track use – a subtle nod to its dual-purpose nature.
