2005-2014 Mustang Horsepower & Torque Ratings
The S197, or fifth-generation Mustang, is the first all-new ‘Stang for the 21st century. Flat, vertical body shapes recall fond memories of the model’s first generation. Significant engine advancements, and 2010 design refresh, help keep Chevy and Dodge competitors at bay.
Let’s look at S197 Mustang horsepower and torque information for model years 2005–2014. This data is gathered from factory-provided numbers and other online sources. The engine output data cited here are based on new, non-modified engines and exhaust systems. Horsepower and torque figures can lower over time and change due to aftermarket modifications.
2005-2010 4.6L Mustang Horsepower
To the casual observer, it may seem that Ford just carried over the 4.6L 8-cylinder for the introduction of the fifth-generation Mustang. While this is technically correct, the reworked Modular V-8 benefits from significant, performance-oriented improvement. Changes begin with a new aluminum engine block that saves 75 pounds. Ford then adapts new cylinder heads from the 5.4L Triton engine. Thanks to a three valve-per-cylinder configuration and variable camshaft timing, the V-8 has improved airflow and a higher compression ratio.
As a result of these engine upgrades, 2005-2009 GT-flavored Mustangs now produce 300 hp and 320 lb-ft of torque. For the updated 2010 Mustang, horsepower increases to 315 while 2010 Mustang torque performance stays the same.
2011-2014 S197 Coyote Mustang Horsepower
For 2011, Ford introduces a new V-8 engine to Mustang GTs. While its 5.0L displacement may bring back thoughts of the old “5.0” Windsor motor, this “Coyote” 8-cylinder is based on the Modular power plant architecture. Dual overhead cams and other technology gives the Mustang a needed boost as the original pony car faces competition from LS3-equipped Camaros and Hemi-powered Challengers and Chargers. For 2011-2012, the Coyote engine gives GTs an impressive performance upgrade to 412 hp and 390 lb-ft of torque. While torque numbers stay the same for 2013-2014, horsepower increases by eight for these years.
2007-2010 GT500 Mustang Horsepower
With the success of previous-generation special edition Mustangs in mind, Ford released the potent Shelby GT500 in 2007. Based on a recently formed partnership with Carroll Shelby, Ford’s Special Vehicle Team (SVT) engineered a high-performance power plant for a factory-built car. The GT500 moves into near supercar status by using a hand-built 5.4L iron-block V8 with aluminum cylinder heads from the Ford GT, quad-valve configuration, and a supercharger generating an 8.5 lb-per-square-inch boost. Other enhancements include modified manifolds and dual custom-tuned mufflers.
The 5.4L V-8 becomes the largest-displacement power plant installed in a Mustang since the 1970s, and, to that point, the GT500 is the most potent original Mustang ever built. Through 2009, output numbers for the Shelby GT500 hit a mind-numbing 500 hp and 480 lb-ft of torque. 2010 Mustang horsepower and torque output reach 540 and 510, respectively. For 2011-2012, the GT500 gets another performance boost to 550 hp and 510 lb-ft of torque.
2013-2014 GT500 Mustang Horsepower
For the last two years (2013-2014) of the S197 Mustang, Ford goes to engine extremes for the GT500. The original 5.4L motor is bored out to a 5.8L displacement. A better Eaton supercharger is used as well. From upgraded head gaskets to a carbon-fiber driveshaft, most of the GT500’s power train components are enhanced to maximize output and power management. Upon its release, the GT500’s 2013 Mustang horsepower is rated at 662 and with torque at 631 lb-ft, making the “Trinity” engine the highest-horsepower engine ever built in North America. This record was later beaten by the various Hellcat/Hemi offerings from Dodge and Ford’s own 2020 Shelby GT500 cranking out 760 hp.
2008-2009 Bullitt Mustang Horsepower
Using the 2001 Bullitt Mustang and the 1968 movie car for inspiration, Ford launches a Bullitt-special edition Mustang from 2008-2009. Based on the GT’s 4.6L Modular V-8, engineers upgrade the motor with a cold air intake system, add a modified exhaust, and increase the redline by 250 rpm to 6,500 rpm. Throttle response is also tweaked for improved acceleration. With output at 315 hp and 325 lb-ft of torque, the Bullitt variant offers a performance bump over the standard Mustang GT. Painted in either iconic Highland Green or black, a total of 6,621 Bullitt Mustangs were made for both model years.
2012-2013 Mustang Boss 302
Take the 5.0L Coyote engine, throw in some engineering magic, and out pops a Mustang special edition for 2012-2013 with 444 hp and 380 lb-ft of torque. The S197 Mustang Boss 302 harkens back to the original Boss 302 from 1969 but benefits from impressive engine technology. These advancements include a chain-driven dual overhead cam, quad cylinder valves, and variable intake and exhaust timing. 3,250 Boss 302 editions were made for 2012 in eye-popping colors like Competition Orange, Yellow Blaze Metallic, and Kona Blue. For 2013, Ford produced 3,553 Boss variants in noticeable colors, including School Bus Yellow, Gotta Have It Green, and Grabber Blue.
Improved Performance For Base S197 Mustang Horsepower And Torque
It’s exciting to talk about drool-worthy horsepower and torque, especially when the conversation involves Mustangs. Yet, not everyone needs a high-power pony car or can afford the insurance premiums that increase along with engine output. Since the S95 Mustang days, Ford made 6-cylinder power standard. The wimpy four-banger from the Fox Body Mustang era is long gone.
For 2005, the Mustang’s base engine becomes the 4.0L single-overhead cam “Cologne” V-6 that started service with the 1997 Ford Explorer. Mustang V-6 enhancements include custom-tuned exhaust manifolds and an updated flywheel. A variable intake manifold and drive-by-wire throttle help to improve power and performance. Base Mustang owners enjoy a respectable horsepower rating of 210 and with 2005 Mustang torque at 240 lb-ft. This base V-6 remains unchanged through the 2010 model year.
Ford’s six-cylinder technology continues to offer impressive results for 2011-2014, the remaining years for the S197 Mustang. Base power for Mustang switches to the 3.7L Cyclone V-6, which was marketed with the “Cyclone” label. All aluminum materials, dual-overhead cams, quad-valve setup, and a dual exhaust help create a sophisticated and responsive power plant. Offering 305 hp and 280 of torque, the Cyclone V-6 was a major improvement of its Cologne V-6 predecessor and even rivaled SVT Cobra performance from the late 1990s. In some driving scenarios, Cyclone-powered Mustangs could exceed 30 mpg. This impressive gas usage was a boon to the Mustang’s marketing message and helped Ford achieve federally mandated fuel economy standards.
