I think we are misplacing a zero somewhere. I did a life cyle analyis of several cars over 300,000 miles and by that time you have basically worn out the car, spent an amount equal to the purchase price on gas and also an equal amount on maintenance & repairs. So for a $23000 Prius, just multiply by 3, and presto, you get $69,000 for 300,000 miles plus insurance. This comes out to 23 Cents a mile, if the Prius used as much gas as an equivalent non-hybrid. The $3.25/mile seems OK for an 18 wheeler truck
Come to think of it, his figures would be more accurate in Mexican Pesos, at the current exchange rate. Was the article translated from Spanish by any chance; they use the $ sign for pesos.
In summary, to calculate the life time cost when comparing one car to another, such as a hybrid, just pro-rate the fuel consumption of the hybrid and then add twice the purchase price for capital and mainteance costs.
As you will have learned by now, gas costs are only 1/3 or less of the total ownership costs, so you have to drive a great deal to make a hybrid pay for itself.
