In 2015, Ford celebrated an all-new, sixth-generation Mustang to mark the pony car's 50th
anniversary. The S550 platform represented the latest in vehicle technology and was
designed from the ground up to foster the international distribution of America's
favorite sports cars. Thanks to the Mustang's global configuration, including a
right-hand-drive model, the 'Stang was the world's best-selling sports car for 2019. Let's review the S550 Mustang horsepower and torque details for the 2015-2021 model years.
This information is collected from factory and online sources. The engine output
specifications cited here are based on new, non-modified engines and exhaust systems.
Engine outputs can reduce over time and change due to aftermarket modifications. If you're looking for more information about the 2015-2021 Mustang, then look no further than our complete breakdown of the

Despite the automotive industry making a mad dash to vehicle electrification, an 8-cylinder
Mustang's continued availability brings comfort to car purists everywhere. While we'll
get into special edition Mustangs and accompanying power plants later in this article,
let's begin with the performance centerpiece for most sixth-generation Mustang
owners—the 5.0L
V-8 “Coyote” engine that traces its origins back to 2011. Starting with
the S550's debut year of 2015, 5.0 Mustang horsepower hits 435 and torque reaches 400
lb-ft. The improvement over 2014 results from a new crankshaft and lighter connecting
rods designed to work at a higher 7,000 rpm redline. Airflow gets better, too, thanks to
reworked cylinder heads, valve train, and an intake manifold. Starting in 2018, a new crankshaft and increased compression ratio—now 12.0:1—help give the
32-valve, dual-overhead-cam Coyote increased output to 460 hp and 420 lb-ft of torque.
Redline now reaches 7,500 rpm.
With a history of successful Bullitt Mustang special editions, Ford launched in 2019 the
third Bullitt Mustang in celebration of the 50th anniversary of the namesake Bullitt
movie. The company's reveal of the car even featured a live presentation by Steve
McQueen's granddaughter. Ford carefully positioned this new Bullitt between the less
powerful GT and the more potent Shelby GT350. Starting with the Coyote 5.0L engine,
engineers added a new air induction system, powertrain control module, and an intake
manifold initially designed for the GT350. An active valve performance exhaust system
added to the Bullitt's features. Beating the GT's top speed by eight mph, the Bullitt
could top out at 163 mph. Engine output reached 480 hp and 420 lb-ft of torque. These
upgrades made the Bullitt, which was also offered for 2020, a tempting option for any
Mustang buyer considering the GT. Of course, the Bullitt came in Highland Green paint,
or Shadow Black if you prefer. For those who may be interested in transforming their standard factory Bullitt into a Steve McQueen Edition Bullitt, then

Following the all-new sixth-generation Mustang launch, Ford announced a significantly
upgraded Shelby GT350 would take advantage
of the S550 platform. A
2014 company news
release highlighted the details of the new GT350, including Ford's desire to make this
special edition very track-focused. To achieve this objective, Ford went with a
"high-revving, naturally aspirated V-8," according to the project's chief engineer,
Jamal Hameedi. He added, "the final product is essentially an all-new power plant unique
to GT350 – and one that takes true advantage of the new chassis dynamics of the Mustang
platform." During the GT350 reveal, Ford went into great detail about the one-off characteristics of its
"Voodoo" 5.2L V-8. The hand-built engine uses a flat-plane crankshaft to reduce overall
engine weight—this allows for faster and higher revs. The crankshaft configuration was a
first for Ford and is typically only found in racing-oriented engines or high-end
European exotic cars. GT350 owners also enjoy a unique exhaust sound thanks to the
engine architecture and quad exhaust setup. Available through the 2020 model year, the
Mustang Shelby GT350 is rated at 526 hp and 429 lb-ft of torque. An "R" version offered
a de-contented GT350 that was better suited for track purposes.
For those believing the GT350 wasn't good enough or spent time drooling over Hellcat-stuffed
Dodges, Ford created the over-the-top Mustang
Shelby GT500 for the 2020 model year. To
call this special edition "extreme" is an understatement. The "Predator" 5.2L supercharged V-8 produced supercar-level power at 760 hp and 625 lb-ft of
torque. The GT500 is the fastest street-legal Mustang produced by Ford and is the
company's most powerful engine ever made. The hand-built engine incorporates a
cross-plane crankshaft, modified roots-type supercharger, and high-performance cylinder
liners and cylinder heads. Ford has limited the GT500's top speed to 180 mph. According
to Road & Track, engineering the car for a 200 mph capability was expensive and
unnecessary for track performance. The publication reports a 0-60 time of 3.3 seconds
for the GT500.
For 2021, Ford said goodbye to the Bullitt and hello to the Mustang
Mach 1. Last seen in
2003-2004, this special edition traces its origins to the original Mach 1 from the
first-generation Mustang. Matching the Bullitt's output specs, the 5.0L V-8 Mach 1
produces 480 hp and 420 lb-ft of torque and benefits from aerodynamic body upgrades.
Together, these enhancements give the Mach 1 a performance boost over the regular
Mustang GT.
For 2015, Ford introduced a 2.3L 4-cylinder
for the Mustang and possibly bringing back
memories of previous-generation models with anemic performance. Other than displacement
size, this new Mustang engine has nothing in common with the old Pinto-based
four-banger. Instead, this EcoBoost power plant, based on Mazda engine architecture,
uses dual overhead cams, a turbocharger, and advanced technology that would put older
V-8s to shame. The output is rated at 310 hp and 320 lb-ft of torque. Quite a step up
from the last turbo Mustang, a 1986 SVO with 200 hp and 240 lb-ft of torque. For 2018,
this engine becomes the base power plant and Mustang torque gets a boost to 350 lb-ft
(horsepower stays the same at 310). Coinciding with Mustang's 55th anniversary in 2020, Ford releases a 2.3L High Performance
Package for base models and creates the most powerful 4-cylinder sports car ever offered
by an American automaker with output at 330 hp and 350 lb-ft of torque. Combined with
upgraded handling elements from the GT Performance Package, the High Performance upgrade
offers an affordable excitement for Mustang buyers.
The Duratec 3.7L “Cyclone” V-6 carries over from the previous generation Mustang and becomes
the base engine for the S550 Mustang at launch. The engine uses a cast aluminum cylinder
block and modern design to produce smooth performance and 2015-17 Mustang horsepower at
300 with 2015-2017 Mustang torque at 280 lb-ft—a solid performer that never generated
the excitement of its more powerful stablemates. The V-6 is dropped from the Mustang
lineup after 2017 when the EcoBoost 4-cylinder becomes the base engine. Note: The best effort was made to reference accurate
