The key on this vehicle was weight reduction, especially in the interior - hence the helicopter style seats. We'll find out when the H4...err..I mean "HX" comes to the market....I mean IF it comes to the market.Hummer GuyThu, 17 Jan 2008 09:27:08 -0000http://treehuggercomments.disqus.com/oh_how_the_mighty_have_fallen_hummers_gas_induced_collapse/#comment-17564575<p>GM never said that they'll end production by 2014, that was a purely speculative date for the production end of the H2 - not the H3, HX, H4, or whatever they choose to come out with next. Or, they'll sell the brand and someone else will come out with it. A brand as strong as HUMMER doesn't simply disappear. </p>Hummer GuySun, 08 Jun 2008 23:29:57 -0000
