The Prius does not even compare to this!
Ohh, in that case lets throw some new numbers at it as a best case scenario. Assume never out of EV mode, but they Prius still gets 46 MPG. The Prius is still using $469.34 a year in fuel vs 0 diesel costs at 6000 miles a year.

Also, looking back, a 5 year pay back may be too unreasonable, so I look at a 7.5 year pay back to 10 year pay back as a good price range. Most people in my family will keep their cars for well over a decade. Hell, I kept my Saturn Ion for 10 years (Bought in Jan 03) before getting rid of it last summer.

at $25,000, it would be 27.69 years
at $22,500, it would be 22.37 years
at $20,000, it would be 17.04 years
at $17,500, it would be 11.71 years
at $16,695, it would be 10 years
at $15,521, it would be 7.5 years

So, for ME, a range of $15,521 - $16,695, or around $16,000 is a more realistic number.

But, the average person drives 15K miles a year, so...

Assume, best case, you make alot of short trips to stay in EV mode and you can get free plug-in charging at all parking lots, and you use very little diesel to get 225 MPG with 15K miles a year. The Prius uses $1,173.59 in fuel, and the Diesel only $259.93.

The break even point vs the $12 Prius:
at $25,000, it would be 14.23 years
at $22,500, it would be 11.49 years
at $21,137, it would be 10 years
at $20,000, it would be 8.76 years
at $18,853, it would be 7.5 years
at $17,500, it would be 6.02 years

$18,853 - $21,137 -- so $20,000-ish for a normal driver
