customers expect and demand capability from the best-selling
heavy-duty truck in America. For most Super Duty owners, it’s the
core asset of their business. Day after day, year after year, it’s
expected to deliver results in the most demanding situations. No
nonsense. And never any excuses.
“Our Super Duty customers do some of America’s toughest jobs,” said
Mark Fields, Ford president of The Americas. “Every day they’re out
there working with little fanfare and all they ask is the right tool
for the job. The new 2011 Super Duty offers them a truck with
best-in-class towing and payload, all-new powertrains and even more
capability than ever to help them do their jobs.”
Ford’s F-Series has been the best-selling line of trucks in the U.S.
for 32 straight years. The new Super Duty further underscores Ford’s
Built Ford Tough legacy.
“The 2011 Super Duty offers the widest array of solutions for the
widest array of heavy-duty work truck customers,” said Chris Brewer,
chief engineer. “The Super Duty lineup offers a variety of body
styles and powertrains, from diesel and gasoline engines, each with
a new six-speed transmission, to pickup trucks and chassis cabs,
each with the towing and payload capabilities that define Super
New diesel and gasoline engines
deliver improved torque, horsepower, fuel economy
For 2011, Super Duty
features both an all-new diesel and gasoline engine that are mated
to a new transmission. The new diesel, the 6.7-liter Power Stroke
V-8 turbocharged diesel engine, was designed, engineered and built
by a Ford team dedicated solely to delivering this class-leading
diesel engine to the next-generation Super Duty to enable continued
best-in-class towing and payload.
Benefits of the new 6.7-liter
Power Stroke diesel engine:
First use of a compacted
graphite iron (CGI) engine block in a Super Duty-class vehicle in
North America; CGI is stronger than cast iron, and Ford successfully
has used the material in engine blocks in products around the world.
The block structure was optimized for reduced weight and maximum
strength to meet the demands of higher torque and more horsepower
and enable class-leading fuel economy.
Unique inboard exhaust
and outboard intake architecture, an automotive-industry first for a
modern production diesel, reduces overall exhaust system volume,
which leads to better throttle response; a reduced exhaust system
surface area minimizes heat transfer to the engine compartment and
improves NVH (noise, vibration and harshness).
features an industry-first dual-sided compressor wheel that works in
a single housing. The unit is uniquely center-mounted on a pedestal
low in the back of the valley for improved NVH. The design allows
the single unit to deliver the advantages of a twin-turbocharger
system in a smaller, more efficient package, combining the benefits
of a small turbocharger (faster response) and a large turbocharger
(ability to compress and force more air into the engine for more
power) in one unit.
The high-pressure fuel system injects fuel at more than 29,000 psi.
The system delivers up to five injection events per cylinder per
cycle using eight-hole piezo injectors to spray fuel into the piston
bowl. The direct-injection system is calibrated and phased for
optimum power, fuel efficiency and NVH.
Aluminum cylinder heads for reduced weight; the mid-deck
construction with dual water jackets provides increased strength and
optimal cooling; six-head bolts, instead of four as found on other
engines, help improve sealing and maintain cylinder integrity even
with the higher firing pressures.
Compatible up to B20 fuel, allowing greener fueling options of up to
20 percent biodiesel and 80 percent petroleum diesel.
“Developing the new
6.7-liter Power Stroke V-8 turbocharged diesel engine was an awesome
endeavor,” said Adam Gryglak, lead 6.7-liter diesel engineering
manager. “After all the engineering and testing, we’re confident
this engine will ensure the new Super Duty continues its leadership
in capability, reliability and productivity.”
The engine and aftertreatment system for the 6.7-liter Power Stroke
V-8 turbocharged diesel powertrain ably meets the new, more
stringent 2010 federal emissions requirements for nitrogen oxides (NOx),
which have to be lowered by approximately 80 percent.
New gasoline engine delivers more torque, horsepower than outgoing
Ford tapped into a bit of its proud racing heritage to create the
new 6.2-liter V-8 gasoline engine, which uses big-bore architecture
to produce horsepower and class-leading fuel economy. The V-8’s
large bore (102 mm) allows for larger intake and exhaust valves for
improved engine breathing, and the short stroke (95 mm) allows
higher engine speed for increased horsepower.
Benefits of the new
6.2-liter V-8 gasoline engine include:
-- SOHC valvetrain
with roller-rocker shafts: The single overhead camshaft (SOHC)
per cylinder head design results in a stiff valvetrain that
allows optimized camshaft lift profiles and results in great
low-speed torque. The roller-rocker shafts allow valve angles to
be splayed, resulting in optimized intake and exhaust port
layout for better breathing.
-- Dual-equal variable cam timing: Intake and exhaust valve
opening and closing events are phased at the same time to
optimize fuel economy and performance throughout the engine
speed range and throttle positions.
-- Two spark plugs per cylinder: Due to the large bore size, two
spark plugs per cylinder are used to more efficiently burn the
fuel-air mixture in the combustion chamber, enabling better fuel
economy and increased engine torque. The twin plugs also help
the engine maintain a smooth, stable idle.
-- Dual knock sensors: A knock sensor on each bank of cylinders
of the V-8 engine allows the spark timing of each of the
cylinders to be individually optimized real time, throughout the
engine speed range. The engine learns the optimum timing via an
-- Better engine crankcase “breathing” and efficiency:
Significant development work and computer-aided engineering
optimized the cylinder block for more efficient airflow in the
crankcase as the pistons move up and down in the bores,
resulting in improved torque at higher engine speeds.
Piston-cooling jets squirt oil on the underside of the pistons
to keep the piston crowns cool under extreme operating
conditions. The cooling jets also allow for a higher compression
ratio for better engine efficiency and faster engine oil warm-up
on cold starts, also improving fuel economy.
-- New TorqShift transmission harnesses and manages the power;
Live Drive PTO available
The all-new 6R140
heavy-duty TorqShift six-speed automatic transmission was designed
to manage the high low-end torque produced by the new diesel engine.
The same basic transmission also is mated to the new gasoline
engine, giving customers of either engine the ability to efficiently
get the increased torque and horsepower to the ground. Engineered
for greater efficiency and fuel economy, improvements include
refined architecture to provide relatively low clutch speeds, which
result in lower drag losses, and optimized fluid levels and
drainback to reduce churning of fluid while also providing superior
In addition to hardware-based improvements, the new transmission
features enhanced Tow Haul with integrated engine exhaust braking
and SelectShift Automatic capability, which includes Progressive
Range Select and a manual mode, allowing customers to select the
gear to suit their needs.
The new TorqShift transmission also enables the first application of
Live Drive PTO (Power Take Off) in a Super Duty-class vehicle. On
2011 Super Duty diesels with the PTO prep option, the PTO output
gear is linked through the torque converter to the engine
crankshaft. This allows the transmission to power auxiliary
equipment such as snowplows, aerial lifts, tow truck lifts, cement
mixers or dump trucks. The power is available any time the engine is
Pioneered on agricultural applications, the Live Drive feature is
particularly useful when mobile PTO function is required during
start-stop operations, such as salt spreading or snow plowing. “A
fully functional Live Drive mobile PTO will allow Super Duty
customers to take full advantage of the equipment on their trucks,”
said Al Bruck, 6R140 transmission engineering manager.
Best-in-class towing and payload;
new towing options
Putting all that power
to work is what defines Super Duty. The 2011 Super Duty features
increased towing and payload capability, extending its best-in-class
rating, and also offering more towing from inside the bed. New is
the first-ever factory-installed and warranted fifth wheel and
gooseneck substructure directly attached to the frame.
“Our system is factory-installed and with a limited warranty from
Ford. The electrical connection is mounted in the side of the bed
wall, providing a clean installation,” said Peter Frantzeskakis,
vehicle engineering manager.
Particularly noteworthy are productivity enhancements to the F-450
pickup to benefit the heaviest-duty trailer tow customers. Unneeded
weight was shed, helping to improve fuel economy and top speed. Even
with these changes, the Super Duty F-450 pickup maintains its
class-leading gross combined weight rating of 33,000 pounds.
Addition of Trailer Sway Control
leads safety enhancements
Ford’s lauded Trailer
Sway Control (TSC) system joins the Super Duty lineup, giving those
customers segment-first capability. TSC is integrated with
AdvanceTrac® with Roll Stability Control™, which now is standard on
all single rear wheel (SRW) configurations.
The AdvanceTrac control module uses additional software to monitor
the truck’s motion when a trailer is attached. Trailer Sway Control
can determine from the yaw motion of the truck if the trailer is
swaying and take measures – such as applying precise braking or
reducing engine torque – to help reduce the trailer sway.
For further peace of mind, the available integrated trailer brake
controller, factory-installed and covered by a Ford limited
warranty, offers smoother and safer operation due to its ability to
interface with multiple vehicle systems.
Normal braking is proportional to driver brake pressure for smooth
brake stops at all speeds. If the vehicle’s Anti-lock Brake System
(ABS) is engaged, the special trailer brake kicks in to minimize the
potential for trailer wheel lock up. In Super Duty trucks with
Trailer Brake Control towing trailers with electric brakes, the Ford
system can, during a sway event, also apply brakes to the trailer to
help stabilize it.
Other enhanced towing, off-road control features and safety
--Hill Start Assist,
which applies brakes to prevent rollback
--Hill Descent Control™, which uses the accelerator and brake to
set, and then hold, the speed
--Electronic Locking Differential, which provides maximum
traction by forcing the rear wheels to turn at the same speed
--Standard tire pressure monitoring system on all SRW (single
rear wheel) models
--Optional side air bags and air curtains
--A new available 4.2-inch LCD screen includes information on
specific features such as Trailer Brake Control and Tow Haul
Improved ride, handling and
steering for a more comfortable experience
In addition to increased
towing and payload capability and improved fuel mileage enabled by
the new powertrains, customers of the next Super Duty also will
benefit from improved ride, handling and steering. For 2011, the
engineering team optimized the frame and suspension of the current
Super Duty, particularly the leaf springs and spring rate, as well
as adjusting the internal valving in all the shock absorbers to
enable greater towing and payload capability with further ride
The steering gear also is new. The 4x2 F-250 and F-350 Super Duty
feature modified steering system geometry to take better advantage
of the twin I-beam suspension, which combines the performance of an
independent suspension with the durability of a beam axle
suspension. Improved response, precision and better on-center
steering and control come from making the steering gear symmetric
left to right.
The result is greater customer comfort, confidence and control in
“A big part of the comfort in Super Duty trucks comes through
controllability,” said Dan Gompper, vehicle dynamics supervisor. “No
matter if the truck is loaded or unloaded, full trailer or empty
trailer, customers can be fully confident.”
Bold exterior, new flow-through
console highlights interior
The new hood of the 2011
Super Duty, with its prominent inverted power dome, complements the
new diesel and gasoline engines lurking beneath. “Super Duty” is
stamped on the upper grille, with a larger Ford oval proudly gracing
Inside, customers will benefit from a new reconfigurable
flow-through console that improves the functionality of the truck.
Storage space is increased about 60 percent, and at least 70
different configurations are possible. A 12-volt powerpoint is
available at the rear of the console and another is located inside
the main bin, which is lockable. A 110-volt power inverter is
standard with all console configurations.
Improved productivity through Ford Work Solutions
For many customers, the Super Duty cab also serves as a mobile
office. Industry-exclusive Ford Work Solutions is part of available
technology to help customers stay connected with their business from
the job site and track tools.
A new available 4.2-inch LCD Productivity Screen allows customers to
take full advantage of the 2011 Super Duty’s capabilities; an
off-road message center has been added as well. The five-way button
on the steering wheel allows customers to navigate through various
menu options – several relating to fuel economy and towing
convenience – never before available on a Super Duty truck.
Continuing the legacy of quality
With all-new powertrains
enabling greater towing and payload capability, safety enhancements
such as Trailer Sway Control added and greater functionality with
available Ford Work Solutions, the new 2011 Ford Super Duty is
poised to continue its legacy as America’s premier work truck.
The accolades the current Super Duty has received, based on 2009
model year GQRS (Global Quality Research System) data, include:
