Does anyone on here know anything about off-roading

The question is:

At what angle can a non lifted H2 be stopped and not turn over? Driver wheels up 30 degrees from the passenger wheels--not front to back.

At Daytona and other race tracks, there can be up to a 33 degree road surface. If I park my Hummer on that surface, will it roll?

The Hummer Site says 40% side slope---wtf does that mean?


I am involved with a NASCAR safety iniative for ARCA and need to know if I can use a non lifted Hummer as a first response vehicle. It would get to the crash site firat and needs to stop to call in other safety vehicles.

So...opinions---are fine---but who has the facts????

That would be interesting parking on a side slope like that...

pucker factor??

In 5 words, percent grade is

"Rise over Run times 100"

or

(rise/run)*100 = percent grade

Where both the rise and the run must be in the same units - typically feet. So, for a rise of 120 ft over a distance traveled of 0.9 miles, it would be

(100 * 120) / (0.9*5280) = 2.52 %

So, by using 40% and some trig, we get 40%= 21.80*

Hey Guys!

Thanks for the info. I did call the Hummer driving academy and they all said the same---22 degrees, and..that it will not roll at 33 degrees but the fluids at 33 degress could hurt the trans if parked for long.

I am working on a neat vehicle for NASCAR tracks--just can't get the ARCA Safety Guy to feel comfortable in an H2. Turns out he uses a GMC 1500 now and the H2 is actually safer for the application we are using--go figure!

The driver should never stop at 33 degrees anyway--just turn up towards the accident instead---not too hard in my book!

****, I would love to run the H2 at Daytona on a 33 degree bank, if it is even that steep---I do not know the actual slope.

Just watch for things falling out the back when you open the tailgate.

I'd have my HGW Girls fall out except they cannot be on the track when there is a caution. They will have to stay inside and watch the wreck.

Daytona:

Talladega:

Typical newer track, Kansas:

My favorite night race, Bristol:

At Daytona, I think the banking is around 30 degrees and not variable. Many of the bigger tracks don't use variable degree banking but it seems like several have/are being re-done to provide it.

Talledega, I think is the one at 33 degrees but Bristol is something like 36 and even the straights are like 15 degrees.

I would think most of the time you would park on the apron anyway. If a pickup can do it, the H2 can as it actually has a wider track width. The 22 degrees that GM says is for a H2 at Max GVW and that includes putting 500lbs on the roof (or whatever the max roof weight is).

John, you may want to consider a smaller lift and wider tires. Make that baby PHAT!!!

Like this :

Well, isn't that a coincidence.

John, I was just talking to Paragon and we both forgot to mention, Daytona is a "self-cleaning" track in the turns. Everything ends up on the apron or in the infield. You would probably never have to stop on the banking other than to let someone jump out and pick something up.

Thanks again to all for the info. The vehicle has to be able to do the 30 degrees even if most wrecks end up on the apron. As far as I am concerned, a GM 1500 is no safer than the H2---but the guy who will drive the vehicle is against the H2 regardless of the facts.

I am working on a sponsorship with ARCA---a series that the big boys send their up and coming drivers to race in--if they do well, they go up to Busch, if not--they go home.

It is great exposure for HGW but the deal is not yet inked. I can give them a truck from Schumacher MotorSports for their safety vehicle but prefer a Hummer H2. Either way, one of my tricked Hummers will be used in the Garage Area at the events.

I cannot ink the deal until the safety guys agree on the first response vehicle. If they don't agree, I am out for now.

I will know tomorrow, but one way to convince them is to test a stock height H2 on the track. We are awaiting Daytona's permission--not easy because the track is so popular.

IF I get the nod to test an H2, who on here is going to drive their stock hight H2 to Daytona and help me out??? by letting us cruise the Daytona track???

I only have lifted ones. The dates are Feb 9-11.

Not stock, but I'll go.

If you don't get anyone from here, I'm sure you could get a loaner from the local dealer for it. Especially if there is a thought that you would by a new/used one from him for this purpose.

Sorry my good friend--it has to be stock height if I get the nod and I can only have one. You know I would love to have you Ken.

THE NOD HAS NOT YET BEN GIVEN--so I am just collecting info now---I do not want to be perceived as a tease on here.
