All of the Mustangs sold between the years 2004 to 2014 fall into a generation named S197. Overall, the S197
Mustangs are marked by their retro, early Mustang inspired looks, numerous technological upgrades, and a large
selection of fan-favorite special editions.
S197 Design Overview
The new Mustang was based on the D2C platform, which Ford also used on the Thunderbird and Lincoln LS. While the
Mustang was still sharing a platform, it was the first new platform for the pony car in 25 years when Ford launched the Fox platform on the 1979 Mustang. Once
the platform had been set, Ford Group Vice President of Design, J Mays, was responsible for the first major redesign
in over ten years.
The result was a new Mustang with a design that paid homage to the past, yet incorporated modern elements to make it
one of the best looking, handling, and performing vehicles of its time. The exterior features a big grille and round
headlights, reminiscent of the 1967-1969 Mustangs, while other elements recall 1965
Mustangs, like the triangular side windows, fastback roofline, and taillights. Inside, the retro cues continue, with the dual-hooded dash and aluminum accent panels, recalling those of the 1967-1968 Mustangs. Big
instruments, circular vents, and a round steering wheel hub complete the retro look.
Modern cues come into play with the changeable backlighting on the instruments, modern suspension components, bigger
brakes and modern engines. The all-new design was unveiled to the public at the 2003 North American Auto Show,
which showcased a Torch Red GT convertible and a Tungsten Silver GT coupe, and was labeled the most significant concept of the show. This design wasn't too far from what was launched for the 2005 model year.
The Launch of the New Model
In early 2004, the new 2005 Ford Mustang
was officially launched. Two models, a V6 and GT, were available, along with numerous trims within each model. The new 2005 Mustang was also available in coupe or convertible formats. The V6 was powered by an all-new 4.0L engine that put out 210 horsepower and 240 lb-ft. of torque, which was a nice increase over the outgoing model's V6
power. Meanwhile, in the GT, the 4.6L V8 was carried over from the previous model but received a nice power boost as well, up to 300 horsepower and 320 lb-ft. of torque.
2010: The Redesign
The S197 Mustangs took on a different look halfway through their lifespan, similar to the SN95 and New Edge
Mustangs. On the exterior, the sheet metal was wholly restyled for better aerodynamic performance. It also included a revised pony emblem, a new headlight design, and LED taillights with sequential turn signals. While it looked
dramatically different, it retained the S197 platform and the exterior dimensions were nearly the same.
On the inside, quality was increased. Ford used better materials, including real aluminum trim, and made their SYNC
system an available option on all models, except the base model 2010
Mustang. It also included upgraded safety equipment to comply with more stringent federal safety standards.
Their performance was improved slightly as well. Ford increased the power available in the 4.6L V8 to 315
horsepower, while the 4.0L V6 was a carry-over from the previous model. All models also included larger standard
and optional wheels, and standard traction control.
For the 2010 model year, the Shelby GT500 also received a sizable redesign. The new GT500 was faster, more powerful
and handled better than ever before. Engine revisions to the 5.4L supercharged V8 resulted in 40 more horsepower and 30 lb-ft. of additional torque. It also received new springs, a new rear differential ratio (3.55), and new
19-inch wheels and tires for better grip. As a result, acceleration improved, with a 0-60 time of 4.3 seconds, and
many drivers reported that it felt like a dramatically different car, especially when cornering.
2011: The Return of the 5.0
While the look of the Mustang stayed basically the same and
overall changes compared to the 2010 redesign were minor, the biggest news of the 2011 model year was the all-new engines and transmissions. The V6 was replaced with an all-new, advanced 3.7L, while the GT featured a
return of the '5.0' engine, though this time as a brand new, highly powerful, modern V8!
The 3.7L V6 featured twin independent variable camshaft timing (Ti-VCT), resulting in much more power, all while
using significantly less fuel. It's made of aluminum, which decreases its weight and increased performance and
efficiency. It produces 305 horsepower and 280 lb-ft. of torque, amazingly just shy of what the old V8
produced. It's also designed to provide more low-end torque, exactly what Mustang owners crave.
However, the real excitement came with the announcement of Ford's new 5.0L
"Coyote" V8. Featuring the same Ti-VCT technology, it delivered 412 horsepower and 390 lb-ft. of torque,
both big increases over the outgoing GT engine. Combined with a lighter overall weight and the new transmissions,
the new 5.0 got even better economy than the old V8 while still being immensely fun to drive. Despite being an
entirely new and very different engine, for long-time Mustang enthusiasts, the return of the 5.0 moniker also
harkened back to the old 5.0 V8 that appeared in the Mustang from the late 1960s until its retirement in 1995.
The 2011 Mustang also received two new
transmissions: a 6-speed MT-82 Getrag manual transmission or Ford's 6R60 6-speed automatic transmission. Both
contributed to the car's better economy and performance, while the extra gear in the manual definitely added to the
fun-to-drive factor as well.
2013: Another Minor Refresh
Another, final update to the S197 was prepared for the 2013 model year. While this one was much more modest than the
2010 update, it did include a new front fascia with a larger grille and standard HID headlights, along with two LED
accent strips that reflect back on the front design of early Mustangs. The rear was also tweaked, with new LED
taillights with integrated reverse lights. LED projector lights on the side mirrors, reflecting the running horse image, were included on Comfort Package models for 2013. The most significant upgrade on the inside was a new 4.2-inch display on
Premium models that was positioned between the speedometer and tachometer that allowed for statistics to be displayed while driving. The 5.0L V8 gained eight horsepower for the 2013
Mustang, up to 420. The Boss 302 remained for one more year, adopting the styling of the new model.
2014: The End of the S197 Mustangs
Very little was changed for 2014. A few colors were added and a few options were shifted around, but all of the
2014 Mustang trims were generally left
unchanged, as buzz continued to build for the completely redesigned version coming for the next model year.
On June 20, 2014, the final S197 Mustang was built. With the advent of the S550 generation, the Mustang continues to
move into the future. Plenty of things changed between the fifth and the sixth generations, and the differences between the 2014 and 2015 Mustangs are numerous. The S197 was a fantastic generation of Mustangs, but time keeps marching on.
S197 Special Mustang Models
V6 Special Editions
For V6 buyers, the Pony Package became available in 2006. The Pony Package included the suspension from the GT,
along with 17-inch wheels with wider tires and a unique grille with fog lamps. It also included a rear spoiler,
unique striping, and emblems. Later on in the S197's run, the Pony Package added a stainless steel exhaust and a
power driver's seat.
At the 2007 SEMA show, Ford launched the V6 Appearance Package. While it included a number of visual upgrades, like
a billet grille, scoops, a spoiler, a grille with fog lights, interior trim updates and blackout trim treatments,
it also had several performance modifications. The suspension was given an upgrade, it received the Ford Power Pack FR1, a
true dual exhaust with X-pipe, a Pro-Cal tuner, a short throw shifter and the FR3 handling package, which included upgraded shocks and struts, front and rear anti-roll bars, lowering springs and a strut tower bar. It became
available for 2008 and 2009, only for Mustangs already getting the V6 Premium Package.
GT Special Editions
The biggest special edition news for 2006 was the return of Carroll Shelby to the Mustang. For 2006, Carroll Shelby
International modified 500 Mustangs into 2006 Shelby
GT-H models, which were sold to Hertz for the revival of their popular "Rent-A-Racer" program. Shelby rebranded the GT-H into the Shelby GT for 2007 and 2008. While the modifications remained the same as the GT-H, the
new Shelby GT was available in numerous colors for both model years, though became best known for its look in
Vista Blue. It became quite popular, too, with more than the planned 6,000 copies being sold.
Also in 2007, Ford reintroduced the California
Special edition after a nearly 40 year hiatus. The GT/CS package adds 18-inch wheels, non-functional side scoops and unique striping in lieu of the GT emblem. The GT/CS Mustang also features new front and rear fascias which are lower to the ground than the ones on the standard GT. Interior upgrades include special floor mats and leather options. Despite this being purely an appearance package, it was popular and remains available on the
Mustang to this day.
For the 2009 model year, Ford celebrated the 45th anniversary of the Mustang and there was no better way to do
that than to create a special edition for GT buyers. While the model was, essentially, a loaded GT, it did include the glass roof option and 45th-anniversary badges. Only a limited number of 45th Anniversary Editions were
After a seven-year absence, the Bullitt made its return in 2008. The Bullitt
was last produced in 2001 and pays tribute to the GT390 driven by Steve McQueen in the 1968 film. Manufactured for both the 2008 and 2009 model years, the
Bullitt maintained the look of the original 1968 Mustang, with no exterior badges or a spoiler, a custom
Bullitt-only faux gas cap, a custom grille and special Dark Argent Gray 18-inch wheels with matching brake
calipers. An upgraded 3.5-inch exhaust tip was added. The Bullitt was only available in Dark Highland Green (like the
movie's Mustang), or black.
Under the hood, the 4.6L V8 was tweaked to produce 315 horsepower and 325 lb-ft. of torque. This was done
through improved calibration, a custom cold air intake, and a revised exhaust, which was designed to mimic the sound of the original Bullitt. It also features an upgraded suspension, which slightly lowers the Bullitt. A manual
transmission was the only gearbox available.
After a 42-year hiatus, the Boss 302 finally made its reentrance into the Mustang scene.
While the 5.0L V8 that was introduced last year was an excellent foundation, designers
wanted to get more track-like performance from the Boss 302, so some modifications were required. It started with a new intake and continued with revised camshafts and a more aggressive tune. The result was 440 horsepower and 380
lb-ft. of torque. That was combined with a race-inspired clutch, intake
manifold, and a short throw 6-speed transmission for an amazing experience behind the wheel.
Based on the Boss 302, two more special editions were also added to the line up: The Boss 302 Laguna Seca and the
Boss 302R. Both were geared towards racing. The Boss 302 Laguna Seca lost some creature comforts but added
performance upgrades, like an upgraded suspension, Recaro seats, and a rear seat delete (with cross-car
X-brace for increased rigidity). The Laguna Seca was meant to bridge the gap between the Boss 302 and the
Boss 302R, which was a race car and not street legal.
After a multi-decade absence, Ford and Shelby again partnered up to bring back the Shelby GT500. The GT500 had a
5.4L supercharged V8 that produced 500 horsepower and 480 lb-ft. of torque. It also included a Tremec 6-speed
manual transmission, custom suspension tuning, a body kit, and custom 18-inch wheels.
An even higher performance GT500, the Shelby GT500KR, was introduced for the 2008 and 2009 model years. It contained
a custom cold air intake and unique tuning, which boosted the power from the 5.4L supercharged V8 to 540 horsepower
and 510 lb-ft. of torque. The GT500 "King of the Road" edition was designed to commemorate the 40th anniversary of
the original edition and featured several appearance and performance upgrades to set it apart from the GT500. Only
1,000 were made for 2008 and 571 for 2009,
with this number matching the original car's 1,571 production.
Not to be outdone, owners could send their already powerful GT500s to Carroll Shelby's plant in Las Vegas where, for
an additional $27.995, it could be rebuilt into a Shelby Super Snake. The Super Snake received either a 605 horsepower
version of the 5.4L V8 or a twin-screw supercharged version with over 725 horsepower.
The 2011 Shelby GT500 received minor tweaks. The
the biggest change regarded the engine, which was no longer based on a cast-iron block, and instead used aluminum. This shaved off some weight and allowed for 10 additional horsepower. Torque was unchanged. Aside from a few other
mechanical tweaks and standard HIDs, the GT500 was unchanged.
Another major revision was in store for the 2013 Shelby GT500. The biggest news: 662 horsepower and 631 lb-ft. of
torque from an all-new 5.8L supercharged V8. It has a top speed of 202 mph. New mechanical features were also added to support the engine and the car's amazing performance, including the Launch Control system that was first seen in the Boss 302. The new GT500 also added many of the styling and performance enhancements that came with the new base
Mustangs, making the car more driver-friendly than ever before. Ultimately, the differences between the 2012
and 2013 Mustangs are individually minor, but altogether significant.
