and Mustang GT fastback customers can also add an available performance
pack for maximum all-around capability, continuing 50 years of Mustang
personalization.
“When we began development of the sixth-generation Mustang, we knew
we had a challenge ahead of us to beat ever-increasing customer
expectations, as well as new competitors in the marketplace,” said Raj
Nair, Ford group vice president, Global Product Development. “We added
content where it mattered – including an independent rear suspension for
better handling and ride, and bigger brakes for better, shorter and
more consistent stops. We also doubled the number of airbags.
“Even with all of that extra hardware, smart engineering throughout
every component of this car enabled us to achieve a base curb weight of
3,524 pounds for the new Mustang EcoBoost fastback – just six pounds
more than the lightest 2014 Mustang V6, and still the best
power-to-weight ratio of any car available in the United States for
under $50,000.”
Building on a solid foundation
With an all-new platform and fully independent suspension, the 2015 Ford
Mustang sets new handling benchmarks for the brand, achieving
world-class performance in both dynamics and ride quality.
“In order to develop precise and predictable handling
characteristics, a car needs a solid platform where the suspension
mounts don’t move relative to one another,” said Tom Barnes, Mustang
vehicle engineering manager. “The structure of the new Mustang is much
more resistant to twisting, with 28 percent more torsional stiffness for
the fastback and a 15 percent improvement for the convertible.”
Despite being so much stronger, this is a very efficient horse, with a
body-in-white that is actually lighter than the previous version. This
was achieved through extensive use of advanced technologies and
materials including hydroforming, laser welding and high-strength
steels. Lightweight aluminum is used for the hood and front fenders to
help reduce body mass and improve the weight balance.
Attention to detail throughout the design process yielded significant
weight savings that helped to offset the increases from adding
performance-enhancing features such as larger, more powerful brakes and
independent rear suspension. The result is a vehicle that is more
capable than before while remaining significantly lighter overall than
key competitors.
The structure of the 2015 Mustang is also designed to meet new, more
stringent crash safety standards. Some of the other components now made
of aluminum include the rear suspension knuckles, rear axle housing on
automatic transmission cars, rear control arms and rear brake calipers.
Even parts made of steel and other materials such as the hollow rear
stabilizer and the new seats have been intelligently designed to meet
performance standards while keeping weight down.
“We added a lot of content to the new Mustang in order to hit our
performance targets and meet today’s customer expectations,” said Dave
Pericak, Mustang chief engineer. “With a base curb weight of 3,524
pounds for Mustang EcoBoost fastback, and increases ranging from six
pounds to 87 pounds for V6 and GT fastbacks, Mustang is still
substantially lighter than the competition.”
Mustang EcoBoost fastback has best-ever weight distribution for a
Mustang, with 52 percent of its weight over the front axle and 48
percent to the rear, while Mustang GT has 53 percent of its mass on the
front wheels. In combination with a lineup of new or upgraded
powerplants, Mustang improves on its already leading power-to-weight
ratios. Mustang EcoBoost carries fewer than 11.36 pounds per horsepower,
while Mustang GT has as little as 8.52 pounds per horsepower.
With a stronger yet lighter structure to build on, the hardware was
added to meet aggressive performance targets. Every new Mustang features
an all-new integral-link independent rear suspension. The suspension
architecture is based on a lower control arm, integral link, upper
camber link and a toe link. The geometry, springs, dampers and bushings
have all been specifically modified and tuned to deliver improved
mechanical grip for this high-performance application.
The new suspension geometry of Mustang now generates twice as much
anti-squat and anti-lift force for better pitch control to keep the body
level under hard acceleration and braking. New aluminum alloy rear
knuckles help reduce unsprung mass to enable the tires to follow the
road for better ride and handling.
At the front, a new non-isolated perimeter subframe replaces several
individual crossmembers to help stiffen the structure while reducing
mass, contributing to a better foundation for more predictable wheel
control that benefits handling, steering and ride quality.
The new double-ball-joint front MacPherson strut system enables the
use of larger, more powerful brakes without resorting to excessive wheel
offsets that would hurt steering feel. Like the rear, the front end
contributes to improved pitch stability with additional anti-dive in the
geometry.
The total system now does a much better job of keeping the four
Mustang tires in contact with the road where they can contribute to
improved dynamics while making cruising and daily commutes more
comfortable.
This is expected to be the best-stopping Mustang yet. Three brake packages will be available:
- Mustang V6, Mustang EcoBoost: Two-piston, 43-millimeter floating
calipers, 320- millimeter rotors, front; single-piston, 45-millimeter
calipers, 320-millimeter rotors, rear
- Mustang EcoBoost performance pack, Mustang GT: Four-piston,
46-millimeter fixed calipers, 352-millimeter rotors, front;
single-piston, 45-millimeter calipers, 330-millimeter rotors, rear
- Mustang GT performance pack: Six-piston, 36-millimeter Brembo™ calipers, 380-millimeter rotors, front; single-piston, 45-millimeter calipers, 330-millimeter rotors, rear
The standard brake package on Mustang GT is equivalent to the system
used for the 2014 Mustang GT track package. The new GT performance
package includes the same brake package found on the 662-horsepower 2014
Shelby GT500.
When maximum performance is needed
“We already set a very high standard for Mustang driving dynamics with
the 2012 Mustang Boss 302, and our goal was to go above and beyond that
with the performance pack on this new car,” said Pericak. “Mustang is
all about performance and customization, and the available performance
packs give our customers what they are looking for straight from the
factory.”
The 2015 model is already the best-handling, best-braking standard
Mustang ever right out of the box. Drivers looking to take their cars to
even higher levels of capability can add a performance pack to Mustang
EcoBoost fastback or convertible or Mustang GT fastback.
Both performance packs get:
- Retuned springs, bushings and monotube rear dampers
- Additional cooling capability for track-day durability
- Thicker rear sway bar
- K-brace connecting strut towers to bulkhead
- Unique tuning for ABS, electronic stability control and electric power-assisted steering
- Center gauge pack
The 2015 Mustang EcoBoost performance package also includes:
- Front brakes: Four-piston, 46-millimeter fixed aluminum calipers with 352-millimeter rotors
- Rear brakes: Single-piston, 45-millimeter floating iron calipers with 330-millimeter rotors
- Unique 19x9-inch alloy wheels painted Ebony Black with Pirelli 255/40R19 Y-speed-rated tires front and rear
- 3.55:1 final drive ratio
The 2015 Mustang GT performance package includes:
- Front brakes: Brembo six-piston, 36-millimeter fixed aluminum calipers with 380-millimeter rotors
- Rear brakes: Single-piston, 45-millimeter floating iron calipers with 330-millimeter rotors
- Unique 19x9-inch Ebony Black painted alloy wheels with Pirelli
255/40R19 Y-speed-rated tires, front; 19x9.5-inch alloy wheels with
Pirelli 275/40R19 Y-speed-rated tires, rear
- Strut tower brace
- 3.73:1 final drive ratio with Torsen differential
- Unique front splitter to channel cooling air to the front brakes
“We set out to create an all-new Mustang that would go, handle and
stop better than any previous Mustang, while also being a better
all-around daily driver,” said Pericak.
The results speak for themselves – during track testing, the 2015
Mustang GT with performance package consistently beat the lap times of
the 2012-2013 Mustang Boss 302.
