I think the battery change is like 7K at the moment but coming down. Yikes! Advantage Hummer, for sure! Add that $7000 in to keep the Prius going another 100k and I'll bet that cost per mile stays right about where it was. No way. They depreciated the entire original cost of the Prius over 100,000 miles to get the cost as high as they did. The batteries are warranted for 100K, but my understanding is they go about 150K. So if you put one new battery pack - at $7K (I think it's more like $5K) and spread the depreciation over 300K - then you'll drop the Prius cost by about 60%. BTW - A Hummer is simply a Chevy Suburban with a different body. So there's nothing highly technical or strongly built about it - unless you are talking about the military Hummer - which would cost a mint to keep going for 300,000 miles. I'm not a Prius lover - but I want people to be accurate in their comparisons.

Wait? How's the Prius going to fall apart?
Last I checked, Hummers (and Suburban, etc) have plenty of problems keeping suspension components working properly. Are you saying the Pruiss is going to have MORE problems? Or are you implying the Unibody frame isn't going to last 300,000 miles? Somewhat confused.
Regardless, the new Hummers 2's use the 6.2L 400hp engine and 6L80 (6-speed) tranny. And, btw, don't forget the 4x4 system as "wear parts" to the Hummer. That's not something that is an issue on the Prius. And I don't the survey account for the energy used in distribution of the fuel. Don't forget the billions of gallons of fuel (diesel?) used in semi's to transport the fuel to the station. There are LOTS of carbon indirect offsets that are often ignored this these idiocracy (is that a word?) comparisons. The article didn't mention lithium technology, which are the hear future battery of choice.
Which, BTW, Toyota lab testing has the batteries exceeding 180,000 miles.
Furthermore (sorry i'm hopping around here, have to get off to New Student Orientation in a second), as previously mentioned, lithium packs can store about twice as much energy and are not nearly as bad for the environment (if they don't use Cobalt). And before anyone harps on NIMH batteries, they better not be using lead batteries in their vehicles. Lead batteries are MUCHHHH more dangerous to the environment than any NIMH battery is. There are HUNDREDS of millions of lead batteries floating around. Only a couple million NIMH's. Additionally, there are several million MORE golf cars floating around using LEAD batteries than there hybrid vehicles. Point in case, I think that's a poor argument to present. It's VERY easily defeated.
Okie, I got to go talk to a bunch of know-nothing freshman (as I laugh at myself because I was in those shoes a year ago)

I did all those calculations for myself on my wife's Hybrid Camry before she bought it.
I determined that the breakeven on the Hybrid system itself - cost wise, not environmental - is at around 60,000 miles for $4 gas, and lower if the gas gets more expensive than that.
The car gets a legitimate 38 miles per gallon around town - whereas a similar Camry would probably get 22-25. It did cost about $4K more than a standard Camry - although the 4 cyl Camry doesn't come with all the bells and whistles the Hybrid has.
The only thing I don't care for is the CV transmission - which I'm not sure my wife even understands what it is, or notices.
We didn't buy it for gas savings, but my wife wanted a new car anyway, so we took a look. Believe me, if it didn't make any financial sense to buy it, I wouldn't have. I also wouldn't have bought a Prius, I think they're ugly, and I just don't like the safety of that size car.
