H2 HUMMER test

Submitted: Thursday, Nov 05, 2009 at 18:03

Robin Miller

Friend of a mate, thru us the keys of his Hummer and shot thru for a holiday
with instructions that we check it out fully and in the bush.

Well, what can you say ! So we agreed to take time out of busy schedule
to test this car to its limits.

Never thought much about these things, just that they are an overpriced piece
of Amercian glitz designed for show , with probably some performance in a straight line but little else.

Note - Don't know much about Hummers so please correct any spec errors I may make.

There are 3 basic Hummers , Military super wide H1((CSI Miami) , the mid size H2 and smaller Cruiser sized H3.


This H2 model tours well with not to much noise up to 130kph and returns about 19lt/100km at 110km pulled along by a huge pertol 6.2lt V8 of 293kw which drives thru an auto box to a constant 4wd system with a slide dash control which gives choices from 4wd high/ lock centre diff/low range &
low range with rear electric diff lock.

We compared it directly to our 4800 manual GU Patrol driving the same courses etc.

First in a short drag race it stayed ahead of the Patrol and looks like a sub 10sec to 100kmh car which is all you ever need in a 4wd.

Most tests were done on our property which allowed for accurate and repeatable results, but first we checked out what I thought was a major reason for owning such a car, Attention getting.

We pulled up outside the Ruffy upmarket cafe, where about 50 people where enjoying their cardonay and cappicino under leafy trees on a lazy sunny morning.

2 wives were appointed as judges, as I thought the decision might be close.

I took off first in my Patrol and 2 customers and 1 dog watched my Patrol leave.

I disputed the results as I was sure a 2nd dog saw me accelerate away.

Next the huge silver and chrome H2 Hummer brick switched on its ignition and the deep burble of the huge V8 drew an instant audience.
As it accelerated away, a little to fast, everyone was watching !
Ok , a qualified Hummer win for round 1 as my car was still covered in mud from escaping Peters Gorge.

Next was a general drive ability test around 50km of dirt back roads some almost 4wd.
The Hummer went and handled really well was quite comfortable and also tracked well easily dodging fallen scrub.

Almost looks at home in the bush
Almost looks at home in the bush


Moved on to 4wd tracks from here which included many tight spots thru thick forrest with bush that touched the car on both sides. The result here quite surprized me as the car followed the Patrol everywhere, helped by good control from its smooth auto and massive low down torque.
Now its a huge machine but when you start breaking down the figures
its not as bad as you would think , e.g. its 2100mm high and its wide but the sides are dead flat, so if you drive slowly and its mirrors don't touch then the car follows without damage.
Indeed its tall mirrors allowed for a full view of the sides and made positioning the car easier than expected.
Now I could have found spots only the Patrol would negotiate but we stuck to existing tracks and it simply drove them.
At times we had to slow right down but only once did we hit an overhead branch. Well the Patrol wins this test.


Next, a favourite of mine, side slope ability. Drove across the Dams wall and I couldn't shake the Hummer here and later research shows this car has a huge track width of over 1700mm and beats cruisers, and its 47 degrees tilt angle is almost as good as the Patrol.

General angles - We drove up a 40 degree dirt wall and the Hummer approach, departure and clearance angles all exceeded that of the GU despite its 3100mm wheelbase (Patrol 2940).
Its standard size 315/70/17 Wheels and BFG AT's helped here.
We then locked both cars rear wheels and drove them nose to tail around in a circle which is a great manovourability test - here both cars turned at about the same rate so we called this even.


Articulation - this should hurt , well we first tried to drive this 3 ton monster onto my articulation ramp but it got up a foot and we heard cracking from the plywood and gave up before it destroyed my ramp.
Then we drove up a long 25 degree slope which intersects another track causing a diagonal hump across the track which twists the cars.
Every leaf sprung car we have tried has needed winching out of this one, and all IFS cars stop. Well the Hummer is not leaf sprung but is IFS, the
Patrol drove thru this and the Hummer tried to follow but got opposing front/rear wheels spinning and stopped.
Patrol was a clear winner here, but a touch on the electric diff lock and Hummer went thru nicely.

Above - both wheels loose traction.

The Wall - this is a short nasty steep slope that really sorts cars out
and no car has yet driven it with normal diffs Patrols included.
The Hummer couldn't make it either, but again a touch on the slick electric locker saw it go up in a credible manner.

General Construction , these cars come to Australia and are converted to RHD at a huge $40k cost and part of our mission was to check this out.
We drove down a steep 30 degree hill, and I got out to check a noise from the engine.
First surprize, the bonnet folds forward and is just a huge plastic moulding, the second surprise was that the long bolt that secures the alternator was floating completely freely and touching the fan intermittantly, so we spent 15 minutes locating an American size spanner and doing the bolt up.
The interior is full of bling and electric everthing, even the door handles and gearstick are wide full hand grip black plastic and chrome affairs.
There was a large amount of squeaking everywhere, you put your hand on an armrest and get a plastic squeak , the dash squeaks and it all seems like a poor quality conversion has been done, however I have to add that one of our RAV4 Toyotas had this plastic panel squeak as bad.

Inside its sort of like your in command of a starship but there is a huge transmission tunnel and the electric black leather seats just didn't provide the leg room of the Patrol.

Underneath the Hummer is a strong chassis with strong protection ladders built in and generally it looks pretty tough, however I wondered at the pressed steel channels that were used to locate the rear axle, these looked much weaker than the Patrols.


In Summary - A surprising package, if you can get over the "Bling" and fuel consumption and have a need for a heavy duty tow vehicle that won't disgrace you in the bush then maybe this is a product to consider, but I won't be rushing out to get one.

The champ also had a separate gearbox for reverse - you could drive as fast in reverse as forward, but it was very easy to roll them.

Great Report Robin. Thanks for taking the time. Having recently traveled with EO members Pete and Sandy and their Milspec H1 I've seen a bit of their capabilities. Theirs seems huge compared to H2. Drove a H2 briefly last year. Felt a bit like sitting in a chop-top as the doors seem so high (or the seats s0o low LOL)

Hi Robin,

Great report as usual. I have driven the H2 petrol version and agree with your assessment, but would have loved to have driven it off-road like yourself. Just one thing, the H3 would be closer in size to a Prado than a crusier. In fact I reckon the cruiser is closer to the H2 in size than the H3!

Would be interesting to put a 200 cruiser on your test track, its traction control should make short work of your test track, but do you count this as lockers :) Also, do you know the side slope angle for the cruiser, just suprises me the GU still has the best angle.

Hi Captain

Thanks - don't know anything about H1 and H3's my wife tells me the Yankee cop shows feature them a bit.

If only I could get a 200 series to play with , I probably wouldn't let the dealer have it back , as it is I just play with what comes along.

On the test track any suspension that gives a car with an open diff and RTI of 600 will keep moving forward.
The 200 series with KDSS should pass , and so may the new Prado.

We have other tests for locker cars and it is tricky as to just where Traction control fits in. But its where it goes that counts and the tests we do seem to correlate well with in bush capability.

I have been told that 200 series is still an acceptable 45 degrees but I do not have a supporting document.

Nissan doesn't get the best figure because of good design , rather it has lighter bodywork up top , its roof line is lower and its just about the only car left with damm heavy axles and diffs.

Hi Robin,

Any time you want a drive of a 200, hop on a plane to WA and your welcome to come bush with me and give it a real workout! And can you bring your ramp with you, I want to try the 200 out on it!!!

I know what its like when trying to compare vehicle offroad capabilities, I once went for a test drive in the Hummer H3 and was under the impression I had booked an off-road drive. Turns out the only off-road bit was going into a carpark and testing how good the low range reduction was by driving up a steep bitumen carpark ramp. I nearly choked laughing when I realised the salesman was serious in thinking the H3 needed low range to manage this steep driveway, then a Pulsar goes by!!!

Nice Offer - with luck I will be over their before gathering next year , so may try to take you up on that Captain.

This link puts 200 series tilt angle at 44 degrees , 1 less than 100 series.

Robin, You are in the wrong business, I'd rather read one of your comparisons than a magazines anyday.! No politics involved, just a good honest comparison. I don't imagine anyone buying the hummer to go too far bush imo?

The Hummer wins the attention getting contest all day everyday, but is that a good thing? yes for those that want the attention, I bet you the dog would take the GU all day everyday.

You make some valid points on the quality control and plastic squeaking, this would be a deal killer for me.

Good read Robin, and after reading your post I started reading 4X4 Australia and an article in it states Hummer is just waiting for approval by US and Chinese government agencies to start building the Hummer in China by a mob called Tengzhong Heavy Industrial Machinery (THIM)

It certainly was an excellent opportunity to give this lumbering behemoth a good test. Naturally we all have different needs and try to either purchase, or modify our vehicles to suit the intended use.

Having owned a number of 4x4's over the years, including FJ45, Bronco, Pathfinder, and now on my fifth Range Rover, I was certainly keen to give the big fella a run.

My current vehicle is a P38 Range Rover 4.6 with front and rear ARB lockers, winchmount bulbar, dual batteries, shower, and a myriad of other ‘trinkets’ which all add to the enjoyment of the vehicle. I’ve always found the ABS difficult to deal with on this model and it certainly isn’t as good a vehicle for extreme off road use as previous Rangies that I’ve owned. But with 285 000kms on her, she doesn’t owe me too much. These days I call on the Rangie more as a tow vehicle for hauling a very heavy race car trailer, but still like the utilitarian aspect of the car. The car suits our three large dogs, it’s super comfortable to drive, fits all our gear, but is a bit thirsty to run, and could do with a few more cubes when the big trailer is hitched up.

Question is, when the time comes, what is out there in the market to replace the old girl. Yes it’s fuel injected and has a few computers on board, but for the most part you can bypass these and limp home if needs be. No ‘hill decent control’, ‘traction control’ or any of the other new fangled toys, just two solid diffs with air bags and shockers.

I recently took a 100 series out for a try. Supercharged 4.5 litre with aftermarket suspension and other goodies. I was seriously disappointed! What a horrid lethargic, unresponsive, wallowing truck. Next I went on to try a later model independent front end in diesel / auto format. Better, driveable, but certainly not in the same class of comfort as our P38. Then it was down to Lexus and drove the V8 versions, in both 100 and 200 series.

The LX570 was great, but just way too pretty to ever take into the mountains, let alone down Robin’s ‘goat tracks’ at Bluegums. The new Rangie hasn’t been considered, I prefer my tow vehicles to have a proper ladder frame chassis under them, and the new Rangie isn’t known for its durability or ease of repair.

What else is out in the market place? Here’s the criteria:
- Proper 4wd with solid chassis.
- Serious engine with decent HP.
- Box shaped cargo area. Most modern 4x4’s slant the rear window for aerodynamics or cosmetics. As a result, the dogs have no headroom and the vehicles are getting harder and harder to load up with camping gear.
- Station wagon design with seating for four or five adults.
- Capable of some serious off road work without adding another $25k or 500 kgs of additional equipment.

So when a mate purchased a 2006 H2 Hummer and offered it to me for a four day weekend. What’s a bloke to do besides ring Robin and see if Bluegums is open for business.

As Robin states, the vehicle was surprisingly capable. Even though it’s somewhat larger than the Patrol, it actually turned 400 – 500mm inside on a 360 degree circle test. It was surprisingly easy to drive through the bush, with great visibility, aided for the most part by the large mirrors, and the fact that; being a box; it was easy to judge the corners of the vehicle.

H2 Hummers are known to ‘relax’ the front torsion bars and long term owners either re-tension the front bars or add a secondary tensioning ‘key’ to their cars. This generally lifts the front up about 50mm and allows better front wheel articulation. My mates H2 has also been fitted with extra heavy duty rear springs for towing the Titanic. These will soon be replaced with the standard factory rear springs going back in. In combination with resetting the front torsion bars, I expect this will have a marked improvement on the current articulation.

On the test day, we did let the tyres down to 30 PSI from the 45 PSI road pressures. Robin was running around at 18 20 PSI in the Patrol, following a harrowing ordeal the day prior. Maybe at a future time we may get the opportunity to re-sample the big H2 with the revised suspension, correct tyre pressures, and a driver that has been in the car for more that 5 minutes of off roading in that car. Let’s wait and see how the Patrol stacks up then!
Would I buy one? Yes, but……………..

I would add additional shockers to the front to assist the standard dampening. I believe that springing would be simply sorted by adjusting the factory torsion bars. The standard steering box is changed for RHD conversion and the fitted box has 4.2 turns lock to lock. The compliance / conversion on this car left a lot to be desired, and I think short cuts were made, the correct ratio box being one of them. I would like to see sub 3.0 turns lock to lock and it would transform this car and improve it’s on road manners out of sight.

See you in the bush……..in a Hummer? Maybe!
