Ram 2500 6.7L Cummins GASOLINE Engine WON'T REPLACE HEMI?? *Heavy Mechanic Review*

I Review the 6.7L Cummins Gasoline Octane Engine rumoured to be going into the Ram 2500 HD pick up trucks and replacing the longstanding 6.4L Hemi engine . I discuss 5 reasons why this new Cummins Gas engine would not be a great replacement in the Ram 2500 trucks for the 6.4L Hemi. starting with the massive weight and COST of these Gas cummins engines.

Earlier in the week we talked about how this 6.7L cummins gas octane engine would potentially be a great fit for the Ram HD pick up trucks and replace the long standing 6.4L Hemi. Well today we are talking some of the reason why RAM may not want to use this 6.7L cummins GAsoline engine.

The first reason is simple. the weight. The weight of the diesel cummins engine is north of 1,000 pounds and well this gas engine is supposed to be very similar and could result in a very similar amount of weight. with the Ram 2500 trucks already being known for light payloads this would cripple the trucks even more having a very very heavy gas engine option.

Secondly the ram 2500 power wagons can't have the cummins gas engine in them because of the special soft suspension set up and so that would be something else Ram would have to deal with.

the second major reason why RAM would not want to use this cummins gas octane 6.7L engine is due to COST. this engine is going to be very similar to the diesel and well the diesel cummins is a $10,000 option so I don't think these Gas cummins engine are going to simply be handed over for cheap. they will also most likely be very expensive which is something I feel ram can't afford.

there ram HD trucks are already priced out of control and this would only make the sales numbers harder to bear having to jack up the gas engine prices another 10k.

the third issues with this cummins gas engine is the low Horsepower rating and low engine speed. this max HP rating is currently sitting at 325hp which is much lower then the 6.4L hemi and very low in comparison to the competition like the 7.3L godzilla from ford.

also is the max engine speed which on the dyno charts cummins released was only at 3,200 rpm which is very very low for a gas engine. all of which may make this engine feel sluggish and slow to respond.

the fourth concern of issues with this Gas cummins engine is fuel economy. I just can't see a large displacement, heavy rotating assembly turbo charged gas engine being very fuel efficient in a 8,000lbs pick up truck.

finally this engine is un-tested and yes it will be using the long standing and proven ISB 6.7L cummins diesel platform but there will be a good chunk of new components and a whole new fueling system as well as new ECU tuning and software all of which has not been proven yet in the real world.

Let me know what you guys think!
