I did a "Break-even point" cost analysis of the Gas engines vs. the Diesel option. This may help buyers determine if it's really worth it to spend the extra $4500 for the diesel engine. I have been as objective as possible on this matter, showing all possible scenarios solely based on the cost difference of the engine itself, not trim or 4wd vs 2wd, and using list prices. I have also ignored differences in maintenance costs; such as adding urea for the diesel, and the Hemi needing new spark plugs every 30k miles.
My calculations are using an 18 mpg average for the Hemi, 19 mpg for the V6, 24 mpg for the diesel, and an average of 15,000 miles per year. I'm using the list prices of $1795 for the advanced technology package, $4500 for the diesel engine, and $2695 for the hemi. I'm also using the average cost for fuel in my area, which is $3.69/gallon for regular, and $3.99/gallon for diesel.
I have created a fairly simple spreadsheet that I can plug different numbers into such as miles per year and differences in fuel prices. The spreadsheet is configured to calculate all changes.
Note that the "technology package" is a forced option with the diesel, so I will show considerations in cost differences regarding that. Personally, I don't need or want a $1795 option to "help" me drive. I do just fine on my own, but thanks anyways.
Break even point considering you purchase the "advanced tech package" on the gas engine options:
V6 = 10.72 years and about 161k miles.
V8 = 3.1 years and about 47k miles.
Break even point considering you DO NOT purchase the "advanced tech package" on the gas engine options, yet you have to buy it with the diesel:
V6 = 15 years and about 225k miles.
V8 = 6.19 years and about 93k miles.
Let me know if this helps you out, or if you would like me to try a different calculation.
