Hummers or Jeeps? We report, you decide...:D

Watch the last 3 minutes of this video...

Compared to this video...

Besides demonstrating the difference in power management, what I would most like everyone to observe is the spotting danger in the Hummer video--If you are spotting someone, DO NOT walk backwards up the trail! Hold your position, and when it is time for you to get further up the trail, stop your spottee, turn and walk up the hill, then turn around and begin spotting again.

End of today's lecture!

Happy trails,

Hi Nena, point taken about spotting. Now to demonstrate my ignorance and ask for schooling. I thought they both did ok, Hummer and Jeep. What is the difference in power management you mention. I seem to have missed the fine point of this.

Hummer kept spinning to get a bite and tearing up the trail, Jeep just crawled right up. Some trails need the extra power, that one doesn't.....this could also be partly driver error.

On the spotting issue.....why would you need one there in the first place!!!!!




I know a guy out east who has a Hummer H3....he said it tows his Sami to the trails really good

Make sure you are comparing the climb UP with the second Hummer, starting at about 5.25 minutes (they did fine descending in the first half of the video). It is a little difficult to see with the reduced sound and video quality of Youtube, but the Hummer is "jackrabbitting" the throttle--on and off, with the motor revving, spinning tires and sliding around on relatively small steps. There are a number of reasons why:

1. Throttle control--by maintaining a steady, smooth application of throttle, you maintain steady and smooth traction. The H3 is stopping when the tires hit a little resistance and then gunning it. In rough terrain, make sure your heel is on the floor, and the side of your foot is braced against the sidewall of the body, so that you can keep your toes and the ball of your foot steady on the throttle.

2. Air pressure--it is possible that by airing down more, his tires wouldn't have bounced back off of the ledges, but rather roll up and over them.

3. Gearing--granted the H3 doesn't have the 4:1 t-case that the Rubicon does AND he appears to have aftermarket tires, possibly larger than stock, and therefore diminishing his effective crawl ratio even more. This can be remedied somewhat by applying left-foot braking techniques to keep from lurching over obstacles. Note that the Rubicon driver didn't have to use left-foot braking, but did have her feet in the position to do so.

4. If all other excuses fail, CLEARLY it was the spotter's fault! ;) :D

I am fairly sure that some H3's have a 4:1 t-case...but with the 4,500+lb Hummer and 5 cylinder engine they just about need it.


It almost looked like he wasn't even in low gear.
