Last Cars Reviews Blog: 2007 Detroit Auto Show: Hummer H3 Open Top Concept

It hasn’t gotten a lot — really, any — press attention at the show, but Hummer brought out an official prototype of a convertible we saw last year. The top is made of canvas but is as sturdy as a convertible top. It slides forward and back, so it can operate like a large sunroof or as a convertible top. It also moves in reverse to give backseat passengers a sunny opening. It’s a nifty idea, but we’re not sure why it’s still in a prototype stage. We’re guessing the company is using the show car to gauge consumer interest, but it sure hasn’t gotten any buzz from the press. The flat paint job and more masculine tires would be a nice addition to the Hummer lineup, too.
