Hummer SUVs get smaller as the numbers in their name grow larger. The H1 Alpha is the "real" Hummer: a civilian (but barely civil) version of the diesel-powered oversize military personnel mover. The gas V8-powered H2 shares engineering with GM's full-size SUVs. The H3 shares much of its substance with Chevrolet's Colorado and runs an inline five from that compact pickup. Whatever size, every Hummer SUV has unabashed and unapologetic styling and off-road ability to back it up. To get the best deal on a Hummer start at Edmunds.com.
