The past
24 months have proven to be a bonanza for the growing pool of diesel truck
buyers. General
Motors and Dodge
have introduced new and significantly better heavy duty pickups, engines
and transmissions offering consumers more choices than they have ever
had before.
Ford, the
perennial volume leader in the segment, could be accused of lagging behind
the others. So when we received an invite out to Bullhead City, Arizona
to test drive Ford's 2003 Super Duty trucks we were a bit skeptical about
its capabilities versus the competition.
Now Ford is reintroducing
the Super Duty, at four years old the eldest of the heavy duty pickups,
with an all-new transmission, a smaller 6.0-liter Power Stroke diesel
replacing the venerable 7.3-liter Power Stroke plus a few other new mid-cycle
updates.
With Ford
selling every Super Duty it can pump out, 65% of which are diesels, we
had to wonder just why Ford picked now to introduce a new diesel powertrain.
The Kentucky production plant where the Super Duty originates is one of
the most productive full size truck plants among the Big Three, producing
nearly 70 trucks per hour with nearly 1 billion possible combinations.
But competitive
pressures aren't the only forces pushing Ford to make this seemingly radical
change. Federal regulations are also a factor. Navistar, Ford's Power
Stroke diesel engine supplier, had to sign a 1998 government consent decree
requiring compliance with 2004 emission standards by October of this year.
The consent decree settled EPA allegations that domestic diesel engine
manufacturers produced engines that utilized a modified fuel management
algorithm than the algorithm provided during certification testing. The
result: higher nitrogen oxide emissions than the levels that were certified.

To comply
with the consent decree 7.3-liter Power Stroke production has been stopped
and replaced completely by production of the new 6.0-liter Power Stroke,
which meets the new emissions mandates.
For more
information on the consent decree and new diesel technology refer to the
following article in Light & Medium Truck Online click on the cover
story titled "Cleaning
Up Engines" by Jim Beach.
The end result
for Ford and 2003 Super Duty owners is that on paper and in real-life
the 6.0-liter Power Stroke provides noticeably improved performance, emits
fewer emissions and delivers an 8-10% improvement in fuel economy over
the 7.3-liter Power Stroke it replaces. Ford engineers were not satisfied
with just beating their own diesel, they also demanded segment leading
performance as well but more on this later when we discuss our driving
impressions.
