Attention: TDR Forum Junkies 
Cummins apparently has an automotive V-8 (and a V-6) in the works for D/C's SUVs (e. g. , Durango) and Ram 1500. They (Cummins) gave a presentation at the 2002 DEER (Diesel Engine Emissions Reduction) workshop in late August. Here's the URL for that presentation (.pdf format):

The conclusions from the presentation follows:
Conclusions
• Light Truck Diesel Family continues to show promise
• Fuel economy advantage is clear, approaching 60 percent
• Performance and sociability are gasoline-like
• Interim Tier 2 emissions, met using known technology
• Final Tier 2 emissions, demonstrated using advanced
aftertreatment devices
• There is a path to market for the Light Truck Diesel
– Cost/Robustness issues resolved
– Variability issues minimized
