@MikeInNH, I’m not looking to get anyone riled up here. I don’t disagree with your math. I just think there is no need for math of any kind. It just distracts from the real issue with hybrids, which has very little to do with price per gallon, miles per year, payback periods etc.
<b>For a great many people the issue is gasoline consumption. Period.
I suggest you get an accountant. You’re going to pay $5,000 MORE for a hybrid…and drive 10k miles a year…for a whopping savings of about $500/year. It’ll take you 10 years to make up the cost difference.
See, the statement I put forth is already being misunderstood or misconstrued. Why would my accountant have any idea how much gasoline a hybrid uses? You’re confusing amount of gasoline with cost of gasoline. My assertion is that a Prius, Insight, Escape, etc., uses less gasoline than a similar car with a conventional engine. The cost of the gasoline is irrelevant, more so with hybrids than with other cars. I’ll take your $500/year fuel savings and say that to the average Prius-owning household that amounts to a fraction of a percent of yearly income. People who buy hybrids aren’t squeaking by on minimum wage or living paycheck to paycheck. Monthly car costs just aren’t an issue to these people. I agree with your math but would simply state it differently, with pride. “I drive a car that gets 48mpg and it only costs me $500/year for 10 years to do so.”
Like I said above, if you can’t afford to save fuel, that’s an entirely separate subject for discussion. For another perspective, you can imagine that a small auto shop generates a dozen empty cardboard boxes per day. Should I just throw them in the dumpster or should I recycle them? Does your answer depend on how much the city charges me to have a recycling bin they have to empty every week?
As for the water pumps, I’m at home, away from my service info, but an 06 Prius will have one water pump for the engine, one for the inverter, one for the HVAC (to keep heat in the cabin when the engine is not running), and I seem to seem to recall something about an aux pump, but I’m not positive. Anyway, it has at least 3, so 4 wouldn’t be a stretch.
