I do not know even if this were to happen in the us if folks would jump on. Diesel fuel is higher, the oil changes, though longer intervals than gas motors, tend to be more expensive and diesel engines can get rather costly to repair or replace. Now, a guy like me who needs a truck to make a living, can definitely use the power, effeciency and durability of a 1/2 ton with a 4 or 5 litre diesel that has a 10 or 11k lb tow capacity and gets 25mpg or more. Would be very interesting to see how it plays out, maybe a trial run with a few models to test the market though I doubt the big 3 are in a financial position to just test the market.I know it is on the high side but if you bump it up to 4.4L and compare it to:
Ford 6.0L- 54.17hp per liter 95 lb ft per liter
Ford 6.7L- 59.71hp per liter 119 lb ft per liter
GM 06 6.6L- 53.03hp per liter 100 lb ft per liter
GM 11 6.6L- 59.85hp per liter 116 lb ft per liter
Dodge 5.9L- 55.08hp per liter 103 lb ft per liter
Dodge 6.7L- 52.24hp per liter 119 lb ft per liter
Cummins ISM 11L- 45.45hp per liter 141 lb ft per liter
Cummins ISL 8.9L- 44.94hp per liter 135 lb ft per liter
Cummins ISX 14.9L- 40.27hp per liter 138 lb ft per liter
If it was 4.4L
@ 200hp & 500 lb ft- 45.45hp per liter 114 lb ft per liter
@ 250hp & 550 lb ft- 56.82hp per liter 125 lb ft per liter
@ 300hp & 600 lb ft- 68.18 hp per liter 136 lb ft per liter
So it looks like getting 300hp might be stretching it a bit too much but the rest of it all looks doable to me.
What I am envisioning is a turbo charged engine tuned for complete combustion with a governed speed of 2800 rpm. I would then treat the exhaust to get the Nox to 2007 levels and the partical level to half way between 2004 and 2007 levels.
Something I would be interested in seeing is how the Nox and partical matter compare from a 2006 dodge cummins vs a 2008 dodge cummins over say 10,000 miles. At some point, any reduction in exhaust pollution is offset by the extra fuel burned per 100 miles when you includ refining and transporting that extra fuel.
