GM 6.6-liter Duramax Diesel

Diesels may be in the dumps when it comes to light-duty pickup trucks but things are starting to get hot in the heavy-duty segment.  New federal emissions rules set to take effect in 2010 have sent Ford and General Motors back to the drawing boards (the current Dodge Ram HD and its 6.7-liter Cummins I6 already meets 2010 emissions).

We’ve previously reported about Ford’s upcoming 6.7-liter eight-cylinder in-house replacement for the current 6.4-liter V-8 Power Stroke, code-named “Scorpion.” Now, we’ve received new information from sources about GM’s updated 6.6-liter Duramax V-8, plus this close-up spy photo.

General Motors uses three letter identifiers to designate each new iteration of Duramax. The current 2007-10 ‘LMM’ Duramax is designed to run on ultra-low sulfur diesel fuel and work with a diesel particulate filter to cut soot emissions by 90 percent from 2006 levels. The LMM replacement is said to be called the ‘LML’ Duramax.
