The 2015 Mustang horsepower figures define the soul of this iconic pony car, separating the casual observer from the driving enthusiast. This year marked a significant moment in the sixth generation of the Ford Mustang, offering a spectrum of performance that catered to both the budget-conscious gearhead and the serious speed seeker. Understanding the specific output and capabilities of each trim is essential for anyone looking to appreciate the engineering that went into this modern classic.
2015 Mustang Engine Lineup and Output
The 2015 model year presented a clear hierarchy of power, starting with the efficient base model and climbing to the thunderous apex of the performance trims. Each engine choice was designed to deliver a specific driving experience, from daily commuter comfort to weekend drag strip dominance. The focus on accessible performance meant that drivers had more options than ever before to tailor the Mustang to their specific desires.
Base and Premium Trims: The EcoBoost Advantage
Starting the lineup, the 2015 Ford Mustang EcoBoost produced 310 horsepower and 350 lb-ft of torque. This turbocharged four-cylinder engine provided an excellent blend of efficiency and punch, making it a popular choice for those who wanted the Mustang badge without the thirst of a larger V8. The Premium trim shared this capable powertrain, offering the same 310 hp in a more feature-rich package.
GT: The Naturally Aspirated Heartbeat
Moving up to the GT model, drivers were greeted by the familiar growl of the 5.0-liter V8, a naturally aspirated engine that has become synonymous with the Mustang name. This configuration delivered a robust 435 horsepower and 400 lb-ft of torque. The GT represented the core driving experience, offering a linear power band and a mechanical feel that turbocharged engines of the era could not always replicate.
Performance Trim Wars: Boss 302 and Beyond
For 2015, Ford revived the legendary Boss 302 nameplate, catering to the enthusiasts who sought track-focused performance and aggressive styling. This was not just a GT with a body kit; it was a thoroughly engineered machine with distinct handling characteristics and a power output that respected its racing heritage. The presence of the Boss 302 significantly elevated the performance conversation for the year.
Boss 302: Track-Ready Ferocity
The 2015 Ford Mustang Boss 302 was a force to be reckoned with, producing an impressive 444 horsepower and 420 lb-ft of torque. This extra power, combined with its lowered suspension, larger brakes, and unique aerodynamics, made it a dominant force in both street driving and track days. It served as the perfect bridge between the standard GT and the race-inspired variants that Ford would later introduce.
Special Editions: The Ultimate Expression Topping the 2015 Mustang hierarchy were the special edition models that took the already potent Boss 302 and amplified its performance and exclusivity. These trims were built for the driver who wanted the absolute maximum from their pony car, often featuring enhanced cooling systems, lightweight components, and track-proven technology.

The crown jewel of the 2015 lineup was undoubtedly the Shelby GT350, a car that redefined expectations for a American muscle car. Packing a high-revving 5.2-liter V8, this track-focused beast produced a staggering 526 horsepower and 429 lb-ft of torque. The GT350 was not for the faint of heart; it demanded respect and delivered unparalleled performance, solidifying the Mustang's legacy as a serious performance machine.
