NEW 2011 MUSTANG MEDIA SITE

DEARBORN, Mich., Dec. 28, 2009 – The 5.0 is back! The 2011 Ford Mustang GT arrives with an

all-new advanced 5.0-liter V-8 engine, developed by a passionate cadre of enthusiastic engineers

who rallied around the common goal of delivering more than 400 horsepower.

The modern 5.0-liter four-valve Twin Independent Variable Camshaft Timing (Ti-VCT) V-8 engine

in the new Mustang GT will deliver 412 horsepower and 390 ft.-lb. of torque. At the same time, fuel

economy is projected to be better than the previous model and unsurpassed in the segment.

“This all-new 5.0-liter engine is the next chapter in the development of the world-class Mustang

powertrain portfolio,” said Derrick Kuzak, group vice president, Global Product Development. “It’s

a thoroughly modern engine for the times, delivering the performance and fun-to-drive factor that

enthusiasts want, while improving fuel economy.”

Coyote in the lobby

Many of the engineers on the development team have worked in the Engine and Electrical

Engineering Building on the Dearborn, Mich., product development center campus. For years they

walked past the original 5.0-liter V-8 Coyote Indy racing engine on display in the lobby, continually

inspired by its mix of heritage, high technology and horsepower.

The powertrain development community had long wanted to develop a new 5.0-liter powertrain,

with strategic discussions beginning in 2000. By 2007, the Mustang competitive landscape was

beginning to change, a sign that the time was right for advancing the Mustang GT powertrain to

world-class levels.

The team began 5.0-liter engine development with the objective of delivering 400-plus horsepower,

on a timetable accelerated by 12 months without compromises in reliability, durability, fuel

economy, or noise, vibration and harshness (NVH) control.

“Nearly all of the team members have worked on other high-profile powertrain programs,” said V-8

Engine Programs Manager Mike Harrison. “They all had a clear vision of the work required on their

particular component or subsystem. Their passion for engines, racing and delivering every last ounce

of performance throughout the engine speed range really demonstrated that they put their heads and

their hearts into this powertrain.”

Development test engines and benchmarks included 5.0-liter blocks, employing different bore and

stroke measurements, GT500 four-valve-per-cylinder heads and cams, various intake manifold

runner configurations, differing compression ratios and a deep-sump oil pan. The team also

evaluated Ford Racing’s 5.0-liter “Cammer” V-8 crate engine for transferable best practices.

Extensive computer-aided engineering (CAE) modeling, development engine experimentation and

evaluation in combination with intricate machine work brought this promising, all-new configuration

to jaw-dropping life in an accelerated time frame.

The result of this development is an “and” solution, not an “or.” 2011 Mustang buyers will enjoy the

benefits of a powerful engine as well as responsible fuel economy.

Ti-VCT

A critical element in the 5.0-liter V-8’s ability to deliver 412 horsepower, with improved drivability,

tractability and fuel economy over the 2010 Mustang GT powertrain, is enhanced Ti-VCT.

For a high-performance application, the team specified cam-torque-actuated variable camshaft

timing. Using existing cam torque energy, with assistance from pressurized oil, meant that minimal

upgrades to the oil pump were required, resulting in less parasitic drag. Increased volumetric and

thermal efficiency gives faster Ti-VCT response at all engine speeds.

During the development phase, camshaft lift profile and port optimization started with higher-lift

Ford Racing aftermarket units, modified for compatibility with various four-valve-per-cylinder

heads. Extensive CAE and dynamometer testing was performed to fine-tune camshaft events and

port flow for performance and fuel efficiency in conjunction with the variable camshaft timing.

The resulting all-new aluminum four-valve-per-cylinder heads feature a compact roller finger

follower valvetrain layout leaving more room for high-flow ports for free-breathing performance.

Head structure was designed to support higher cylinder head pressures and cross-flow cooling for

sustained high-rpm use. Head bolt size was increased from 11 to 12 millimeters to contain the higher

combustion pressures.

The aluminum block was developed for optimized windage and oil drainback under lateral

conditions and high rpm, such as a track-day outing for an enthusiastic owner and driver. Increased

main bearing bulkhead widths and nodular iron cross-bolted main bearing caps with upsized bolts

were also employed to accommodate the significant performance increase.

An additional element is the increased capacity and baffling of the deep-sump stamped steel oil pan

to enable sustained high-rpm use and offer the convenience of 10,000-mile oil change intervals.

Piston-cooling jets also were incorporated for performance-minded customers and for faster oil

warm-up on cold start.

Specially designed tubular exhaust headers were developed to maximize exhaust pulse separation

and improve flow. A team analyst actually fabricated the tubular headers in his home workshop,

bringing the CAE design to life.

Performance and fuel economy

The 412 horsepower and 390 ft.-lb. of torque delivered by the 2011 Mustang GT 5.0-liter V-8

represent significant increases versus the 2010 model year output levels.

The six-speed automatic transmission on the 2011 Mustang GT will deliver up to an estimated 25

mpg highway and 17 in the city. This is up from 23 mpg highway and 17 city for the 2010 model.

Six-speed manual transmission Mustang GT models for 2011 are projected to deliver 24 mpg

highway and 16 city, matching the 2010 model but delivering significantly more horsepower and

performance feel.
2011 Mustang GT fuel economy is enabled by the Ti-VCT, the six-speed transmissions in automatic

or manual variations, EPAS and an additional rear decklid seal to enhance aerodynamics.

Fuel economy also is aided by engineering a lightweight powertrain. The engine, as shipped, weighs

just 430 pounds. This represents a weight savings of more than 20 percent versus the previous

5.0-liter offering. Lower mass can be attributed to the aluminum block and heads, the lightweight

composite intake manifold, composite cam covers and hollow camshafts.

Improved driving dynamics

EPAS has made a dramatic contribution to Mustang GT driving dynamics, delivering quicker

on-center steering response, increased effort at highway speeds and reduced effort required in

low-speed parking maneuvers. EPAS allows specific tuning for the Mustang GT application.

The 2011 Mustang GT features an enhanced rear lower control arm to add stiffness, improve

powertrain NVH control and sharpen handling. A stiffened rear stabilizer bar for better on-center

steering is also included. Stabilizer bar diameters, spring rates and dampers all have been tuned for

improved dynamics.

A Brembo brake package upgrade will be available for serious enthusiasts. This package includes

14-inch vented front discs from the GT500 Mustang, unique 19-inch alloy wheels and summer

performance tires.

Added convenience content

For 2011, Mustang GT offers drivers several new convenience technologies, including:

Standard message center

Integrated blind spot mirrors

MyKeyTM programmable vehicle key

New look

From the 5.0 fender badges to the new engine cover, Mustang GT honors and continues the proud

heritage of its predecessors. The speedometer increases to 160 mph and the tachometer redline

advances from 6,500 to 7,000 rpm.

Three vibrant new colors will be added for 2011 including Yellow Blaze Tri-Coat, Race Red and

Ingot Silver.

Improved NVH control and convertible rigidity

For 2011, Mustang GT benefits from across-the-board NVH improvements. These include

additional sound-deadening material on either side of the instrument panel, additional sound

absorbtion behind interior trim panels and a real wheel arch liner to reduce noise on gravel or wet

surfaces.

Mustang GT convertible models feature enhanced structural rigidity, with lateral stiffness improved

by 12 percent versus the 2010 model. A tower-to-tower front strut brace is now standard, and the

V-brace has been stiffened by adding gussets. The secondary crossmember also has been stiffened

while a front Z-brace has been added, connecting primary and secondary crossmembers. A-pillar

stiffening foam also has been added to increase rigidity.

“This powertrain honors Mustang’s heritage by raising the bar on performance while increasing fuel

economy,” said Barb Samardzich, vice president, Powertrain Development. “For enthusiasts, such as

the passionate members of the 5.0-liter V-8 team, it’s like having your cake and eating it, too.”
