FORD ANNOUNCES NEW 6.0-LITER POWER STROKE DIESEL TRUCK ENGINE
DEARBORN, Mich., May 28, 2002 – Ford Motor
Company today announced it will introduce an all-new 6.0-liter V-8
diesel engine and a heavy-duty 5-speed automatic transmission
beginning in early 2003 for its F-Series Super Duty pickup and Ford
Excursion sport-utility vehicle.

and TorqShift automatic
The new, more powerful, cleaner 6.0-liter Power Stroker
Diesel and new 5-speed TorqShiftr automatic transmission will
combine to make a best-in-class 325 horsepower at 3,300 rpm and 550
foot-pounds of torque at 2,000 rpm.
The new diesel will offer up to 10 percent better fuel economy and
20 percent lower emissions. The new diesel also has reduced noise
levels and has improved speech intelligibility while driving by more
than 20 percent.
“Truck customers are demanding more power, better NVH and increased
fuel economy,” said Dave Szczupak, vice president, Powertrain
Operations, Ford Motor Company. “By combining best-in-class power,
towing capability, fuel economy and more refinement, we are
delivering the package our customers want.”
Richard Fotsch, president of International Engine Group, an
operating company of Navistar International Corporation and
manufacturer of the new Power Stroke Diesel added: “This is a real
step forward in diesel technology for our truck customers. We
continue to improve performance while at the same time improving
fuel economy and meeting clean-air goals.” 6.0-Liter Power
Stroke Diesel: 32-valve V-8 diesel
The new 6.0-liter Power
Stroke V-8 engine is a direct injection, 32-valve diesel with an
all-new cast-iron block and cylinder heads. The engine employs a
single, block-mounted camshaft in a compact over-head valve (OHV)
design, with hydraulic-valve lash adjustment. This proven
configuration provides a low-friction and durable valvetrain system
and is ideal for engines with a normal operating range of less than
4,000 rpm. This design provides maintenance-free longevity, quiet
operation and optimized performance over the life of the engine.
First shown in concept form at the North American International Auto
Show in January, as the engine powering Ford’s Mighty F-350 Concept
Truck, the new 6.0-liter Power Stroke Diesel incorporates a number
of diesel engine innovations, including:
Variable Response Turbocharging (EVRTT): A system
that helps ensure exceptional turbo boost over a wide range of
engine revolutions for impressive grade climbing capability,
high-altitude performance and towing capability. EVRT employs a set
of vanes that automatically adjust to optimize the airflow within
- Tow-Haul Mode: The new powertrain features a
“tow-haul mode” that, once activated, can help increase a driver’s
feeling of control when towing large loads up and down steep grades
and automatically minimizes shifts and maximizes available torque.
Upon descent, the tow-haul mode utilizes engine braking to help
extend brake-life and improve driver control.
- Hydraulic Rail
Fuel Injection: Fuel injectors are actuated by a high-pressure
hydraulic rail system that generates injection pressures up to
26,000 psi. The high-pressure fuel is quickly atomized as it is
released into the combustion chamber, generating a clean and
efficient combustion event.
- Pilot Injection: By
delivering small quantities of fuel into the combustion chamber
prior to the main injection event, the combustion process is both
smoother and quieter.
- Exhaust-Gas Recirculation (EGR):
Cooled exhaust gases are re-circulated back into the combustion
chamber, lowering the burning temperature of the combustion event
and, as a result, reducing oxides of nitrogen (NOx).
- Ease of
Maintenance: The oil filter is located on top of the engine, so
it can be easily removed. An innovatively designed oil cartridge,
similar in concept to a printer cartridge, keeps oil self-contained
during a filter change and the engine free of dripping oil during
Diesel market leadership
Power Stroke Diesel is the best-selling engine, gas or diesel, in
this segment,” said Tim Stoehr, Ford Division Super Duty marketing
manager. “Two out of every three F-Series Super Duty trucks we
build have a Power Stroke engine. Ford has been offering diesel
engines since 1982 and has been the dominant player in the segment.
We expect the new 6.0-liter will be very well received, not only by
our own customers, but by competitive customers as well.”
Ford’s proven diesel powertrain – the current F-Series Super Duty
7.3-liter Power Stroke Diesel – also has been improved five times
since its introduction in 1994. Beginning this January, Ford began
offering a new best-in-class torque Power Stroke 525, which delivers
525 foot-pounds of torque at just 1,600 rpm on automatic
transmission-equipped Super Duty models. The updated powertrain,
which includes noise reductions, is rated at 250 horsepower. The
7.3-liter Power Stroke Diesel also is offered as an available engine
in Ford E-Series cargo and passenger vans.
“These over-8,500 pound pickup truck customers use their trucks for
a variety of purposes,” said Charlie Freese, chief diesel engineer,
Ford Motor Company. “Whether it is for commercial use or for towing
horse trailers, boats or custom cars, we want our customers to have
enough power and low-end torque to get the job done.
“The F-Series Super Duty with a Power Stroke Diesel is a well-proven
combination: 98.9 percent of all trucks with Power Stroke Diesel
engines built since 1994 are still on the road,” Freese added.
The new 6.0-liter Power Stroke Diesel will be
built later this year at Navistar’s Indianapolis Engine Plant for
high-volume F-Series Super Duty trucks and at its new plant in
Huntsville, Ala. for other applications. The 5-speed TorqShift
automatic will be built at Ford’s Sharonville (Ohio) Transmission
The new powertrain will be available on mid-2003 model year F-Series
Super Duty and Excursion models.
