V8 turbo diesel engine
- Upgraded 2015 Ford F-450 pickup offers more towing capability than
- 2015 Ford F-Series Super Duty King Ranch restyled, combining
authentic Texas heritage with modern luxury
DALLAS, Sept. 26, 2013 Ford, America's truck leader, introduces the
2015 F-Series Super Duty lineup today at State Fair of Texas,
featuring a second-generation 6.7-liter Power Stroke® V8 turbo diesel
engine; increased towing capabilities; and a refreshed, Texas-inspired
King Ranch model.
"Truck leadership means never resting, and the Super Duty team
has been tireless in finding ways to improve the industry's most
popular heavy-duty pickups," said Joe Hinrichs, executive vice
president and president of The Americas, Ford Motor Company.
"Super Duty diesel customers will benefit from improved
performance and features backed by outstanding Built Ford Tough
Since the 6.7-liter Power Stroke V8 turbo diesel debuted in 2011, Ford
engineers have listened to customers and continued to examine each
component of the engine to develop improved performance.
Ford is the only heavy-duty pickup truck manufacturer that designs and
builds its own diesel engine and transmission combination, ensuring
the powertrain will work seamlessly with all chassis components and
vehicle calibrations from concept to execution. This approach also
enables Ford engineers to optimize the vehicle's performance across
the entire lineup.
A key Ford innovation on the original 6.7-liter Power Stroke V8 turbo
diesel was its so-called reverse-flow layout. The advanced design
places the exhaust inside the engine's V-shape while the air intake is
positioned on the outside of the V. This segment-exclusive design
naturally improves a variety of attributes:
- Shorter airflow from the exhaust system to the turbocharger sitting
between the engine's cylinder banks improves turbo responsiveness
key to providing torque quickly to truck customers when they need it
- Positioning the turbo inside the engine's valley helps isolate the
engine's hottest temperatures, improving performance and efficiency,
while also reducing noise, vibration and harshness
Ford engineers built upon the many benefits of this design as they
upgraded the Power Stroke. One improvement is a larger GT37
turbocharger that replaces the previous GT32 model, enabling more
airflow to the engine to produce more power beyond today's 400
horsepower and 800 lb.-ft. of torque.
Key components of the new GT37 turbocharger
The GT37 features a single, larger 88-millimeter compressor wheel that
replaces the GT32's dual-sided compressor design. The compressor
forces air into the engine's cylinders to improve performance
especially at high altitude where the air is thinner than at sea
level. The turbine size is increased to 72.5 millimeters from 64
millimeters, so exhaust gases have a larger surface area to spin the
turbo, providing extra power. The wastegate and the wastegate controls
are eliminated, because the turbo operates at lower peak pressures
than the GT32.
"The original designers of the current Power Stroke V8 diesel
forecasted needs for higher output. This facilitated the larger
turbocharger, increasing airflow and creating more power," said
David Ives, Power Stroke technical specialist. "We've
dramatically improved performance while reducing overall engine
complexity by focusing on the turbo system."
A further benefit of the larger turbo is improved engine exhaust
braking, manually controlled by a push-button switch on the dashboard.
Extra braking power helps reduce wear and tear on wheel brakes and
requires less manual brake application from the driver, especially on
Fuel system improvements
Turbo changes drove improvements to the fuel delivery system,
specifically a new high-pressure fuel pump and fuel injectors. The
pump's cam stroke is increased to deliver more fuel when desired for
increased power. All-new injector tips better atomize the fuel,
resulting in improved combustion that enables lower noise, vibration
and harshness. Other benefits include cleaner emissions and a
reduction in the buildup of fuel deposits on the valves over time.
In addition, a new exhaust temperature sensor enables more accurate
fuel control, which improves both durability and driveability
especially when towing and helps the customer drive the Power Stroke
diesel to its maximum capability.
Even though the fuel system delivers extra fuel as needed to provide
more power, other efficiency improvements ensure 2015 Ford F-Series
Super Duty pickup customers see similar performance to today's
best-in-class fuel economy.
Further enhancements to Ford Power Stroke diesel include:
- Ford-designed and -engineered 6R140 TorqShift® six-speed
transmission uses a new torque converter to manage increased
horsepower and torque
- New polymer coating on main bearings for improved wear-and-tear
durability and lower friction
- Improved crankshaft fillet design the transition point between the
crankshaft's journals to increase crankshaft power carrying
- Increased crankshaft damper weight to reduce rotating forces on the
crankshaft when the engine is performing at peak power levels
- New five-layer head gasket to handle wider range of engine firing
pressures resulting from more powerful engine performance
- Added material to the engine's cylinder heads, exhaust manifold and
valvetrain to handle increased power levels
- Redesigned turbo oil and cooling lines to improve sealing
- Piston assembly upgrades to increase load-bearing capability
- New four-layer exhaust manifold gasket for improved durability
2015 Ford F-450 upgrades
The 2015 Ford F-450 tops the F-Series Super Duty pickup truck lineup
with maximum towing and hauling capability. Changes for 2015 include a
strengthened frame, suspension, new commercial-grade 19.5-inch wheels
and tires, and core work components shared with F-Series Super Duty
chassis cab models.
Just as the next-generation Power Stroke engine reflects changes that
improve power while maintaining durability, the Super Duty engineering
team took specific actions to bolster key F-450 components to improve
towing capability, including:
- Upgraded rear driveline U-joints
- Upgraded suspension components, including new rear leaf springs,
front and rear stabilizer bars and shocks
- Increased fifth-wheel and gooseneck trailer capacity
- Stronger steering gears and steering linkages
- Larger brakes shared with Super Duty chassis cab models, including
wheel brakes, parking brake and new antilock brake calibration
- F-450-specific Power Stroke diesel engine calibration
King Ranch expresses authentic, rugged luxury
The reinvigorated update to the 2015 Ford F-Series Super Duty King
Ranch edition is inspired by the place where American ranching was
"King Ranch is an American original with a proud heritage of hard
work that defines the American ranching lifestyle," said Doug
Scott, Ford Truck group marketing manager. "The 2015 Ford Super
Duty King Ranch seamlessly combines elements of Texas-inspired luxury
and Ford capability."
As part of the Ford Truck commitment to continuous improvement, the
F-Series design team traveled to King Ranch, founded in 1853, for
fresh perspective and inspiration from the 825,000-acre working ranch,
which is bigger than the state of Rhode Island.
"What really stood out is how prominent the 'Running W' is, and
how it defines and unifies the ranch," said Barb Whalen, Ford
color and material design manager. "Similarly, we wanted that
brand to define the new Super Duty King Ranch."
On the new Super Duty King Ranch, the Running W the brand used on
cattle raised at the ranch provides a focal point for the interior.
It is cut out and stitched to make the seat backs and center console
appear to have been branded.
A lighter, richer shade of Mesa leather trims the seats, center
console lid, armrests and steering wheel.
Exterior updates include the new, darker Caribou paint for the wheel
lip moldings, bumpers and lower body. The bed rail caps, bumper caps
and running boards are executed in black. The Running W brings focus
to the wheel caps as well.
"Through premium materials and thoughtful execution, we strived
to make the 2015 Ford Super Duty King Ranch have a look and a feel as
authentic as the ranch itself," said Scott.
