Reality? Hummers have nearly the worst reliability ratings of any vehicle. Prius has the best customer satisfaction rating and an extremely good reliability rating.
You can choose whatever you want and it doesn't matter at all to me, but this post is filled with fallacies.
At the extreme the most environmentally friendly personal transportation is a motorcycle but it also comes with the highest personal health care costs. If you value the life and health of your wife and children an SUV engineered for occupant safety is a far cheaper total cost of ownership way to go.
The number don't work out. For starters - the Prius has an expected lifepan of only 100K miles? That just does not line up with typical Toyota quality or durability.
Second, the Hummer, though an interesting vehicle is no likely to go 300K miles. Remember, it is made by GM.
Third - other than the cost of the battery in the Prius, the Hummer contains more metal, more plastic, more mechanicals (engine and drivetrain) than the Prius.
I am not questioning the expense of regular maintenence on the Prius, but overall, there is just NO WAY the numbers work out the way they are implied in this article.
I know exactly two people with a Prius - one has had theirs for a couple of years and have 45K miles on it. They are extremely happy. The costof ownership has been quite low - as they have had no trouble whatsoever with it. And they average on combined driving over 50mpg.
The other has only had their Toyota a couple of months, but so far, have commented on how tight the car is built and how great the fuel economy is.
A Hummer, on the other hand (which one are they using for comparison?) is heavier, and gets FAR lower gas mileage (an average of 9-10mpg for an H2 - the most popular model). He cheaper, and slightly smaller H3 gets between 13 & 16 mpg. And the H2 costs approximately twice the cost of a Prius, while the H2 costs about 20% more than the Prius.
So, while I am not a potential Prius buyer (I much prefer the full-size vehicle like my current Tahoe, or a full-size pickup), I won't go around dogging the little hybrid car. The numbers just don't add up like the author would claim.
