This month's Consumer Reports magazine has a review of "luxury SUVs". I would normally not even look at them, but I noticed that the Hummer H2 was listed, and I thought "maybe there is some redeeming value to what most people think is an anti-environmental piece of shit".
I was wrong. The ratings table for the whole review has 17 vehicles, the first 16 of which get "Overall road-test scores" of 83 down to 61. Number 17, the H2, got a score of 23. And it also got the lowest MPG in the table. And it cost $20,000 more than the number 2 car.
The CR ratings are available online, but not for free; on the other hand, you can probably save the cost of a year's worth of access to the online content ($26, or $19 if you have a magazine subscription) with one purchase based on their comparisons. Having said that, I hope that quoting the first sentence of the H2 review is considered fair use (and good advertising for the magazine, which I have read religiously for 35 years): "The Hummer gets awful fuel economy, handling is ungainly, the brakes are sub-par, and a terrible view makes it difficult to judge the hulking vehicle's position within a traffic lane."
So, when I see someone driving a Hummer, I will not only think of them as environmentally unfriendly, but crappy shoppers as well.
