Los Jalops are calling Ford Motor Company to task on claims of clean diesel leadership in heavy duty pickups. Ford's Earth Day Press Release, highlighting ten green initiatives that Ford is committed to, contains this item at #3:

"Ford Introduces First Clean Diesel in Heavy-Duty Pickup Segment - Ford is leading the diesel revolution with the 2008 Super Duty, offering the segment’s first clean diesel engine. The new 6.4-liter diesel utilizes Ford Clean Diesel Technology™ and meets the most stringent emissions standards in the world while increasing power and torque in an engine that is smooth and quiet. The 6.4-liter PowerStroke® clean-diesel makes an impressive 350 horsepower at 3,000 rpm and 650 foot-pounds of torque starting at 2,000 rpm while reducing particulate output by up to 97 percent to a level on par with gasoline engines."

While technically the 2008 Ford Super Duty was the first diesel powered heavy duty pickup to reach dealerships in January 2007 with an emissions system up to the task of meeting tough new 'Tier 2 Bin 5' EPA standards, it's the new 2007 Dodge Ram Heavy Duty and its 6.7-liter Cummins I6 engine, that recently went on sale, that's rightfully in the pole position for clean diesels.

Tier 2 Bin 5 specifies a 10-fold reduction in particulates/soot (to .01-grams/mile) and a 2-fold cut in nitrogen oxide (NOX) emissions (to .07-grams/mile) from previous standards. While the new particulate limit has already taken effect as of January 1st, the NOX portion is being phased in between 2007 and the end of 2009.

The PowerStroke just misses hitting the new NOX limit, but Dodge and Cummins have the full public endorsement of the EPA that the I6 is already below January 1, 2010 NOX levels - at a measly .05-grams/mile. The Dodge Ram is so clean it even beats the emissions of the tiny Smart Fortwo .08-liter CDI.

So, who's the clean diesel leader? We'll let you decide.
