I'm guessing they didn't have enough sales to keep it. Probably correct. The lower price of the 6.8 is offset by lower residual values and perhaps those fleet buyers looking at it quickly worked out that the 7.3 was a better proposition that ends up cost neutral? It’s also vindication of all the work Ford did on settling on the 7.3 liter capacity in the first place.

jpd80 Posted September 28 Share Posted September 28 I was watching a YouTube about the new GM Duramax 8.3 V8 diesel - 555 hp and 1,230 lb ft Gale Banks mentioned that Ford is rumoured to be working on a new 8.0 liter diesel. I can’t imagine Ford letting GM get the lead on a new diesel engine in Super Duty for too long. Quote Link to comment Share on other sites More sharing options...
akirby Posted September 28 Share Posted September 28 Current Ford 6.7L is already 500/1200. Quote Link to comment Share on other sites More sharing options...
fordmantpw Posted September 28 Share Posted September 28 HP wars like this are ridiculous. You won't notice the difference between 500/1200 and 555/1230. Both use torque management to protect the driveline in the lower gears, so off-the-line feel will likely be similar. Maybe towing 40k lbs. you would notice a small difference towing up to the Eisenhower tunnel, but 99% of people won't notice an appreciable difference. Pretty sure the 330/950 coming in my cab & chassis will be sufficient for my use (~24k loaded). 4 Quote Link to comment Share on other sites More sharing options...
Flying68 Posted September 28 Share Posted September 28 The whole point of the larger displacement, and as shown by his HP/L metric is to lower combustion temperatures so that NOx emissions are lowered, so that they can work to eliminating DEF. EGR and the DPF are going to remain, but if they can lower NOx enough, you may not need regen on the DPF. If Ford goes to 8.0L I would expect similar power numbers as the GM 8.3L.

I remember a few years, going to the Chicago Auto Show, seeing Ford/Dodge/GM banners proclaiming their increases in horsepower and/or torque, making them the new King of the Hill. I always figured if it means the manufacturers are actually paying attention to improving those engines, I'm all for it. Quote Link to comment Share on other sites More sharing options...

NOx and regens are not related to each other. NOx necessitates DEF, soot necessitates the DPF and regens. 1 Quote Link to comment Share on other sites More sharing options...
