[H3 Hummer]

Here is some good info. including a little about the drivetrain

Combining a five-speed-manual first gear and an optional transfer-case low-range ratio of 4.03:1 (industry leading), the H3 has a crawl ratio of almost 69:1, where most other serious 4x4s are doing well with a 35:1 ratio. The 4.03:1 low-range transfer case is also offered with the four-speed automatic (the 4L60-E), also offering an impressive 56:1 crawl ratio. Further, Hummer engineers had to make suspension changes to allow the H3 wheels to droop and flex over ruts, holes, and rocks with poise and confidence. And although there's no anti-roll bar disconnect, trail flex was impressive for the smallish brute. The H3 will offer 32-inch Bridgestones that performed amazingly well, conforming like marshmallows over the jagged surfaces, once we took out almost 20 pounds of tire pressure.
