HUMMER launched a concept car at the Detroit Motor Show in January 2008 in the form of a HUMMER HX.
HUMMER H3T pick-up was introduced at the annual Chicago Auto Show in February. The car model is available with a 3.7-litre Atlas straight five engine as well as a 5.3-litre V8 engine in an Alpha version. It also has a longer wheelbase than the standard H3.
