Hummer H2 Towing 0-60 MPH Test - Does it Explode? 

The best feeling after a winter is cutting that shrink wrap off. It’s like christmas in the spring.

9.6 while towing with that older 6.0 isn't bad.

The 08-09 had the 6.2 with a 6 speed auto trans that made them a bit quicker. They also had dual electric fans to cool the engine and it helped keep those transmission temps down.

I love my 04. With a knn cold air and a flow master exhaust, dual to single, I average 13.9 city/freeway combined. Like andre I love the thing. Especially camping and offloading.

6.0 was a great engine in a chassis cab 3 yard dump we had. absolutely tortured it and it started every day!

That's not bad at all. I'm always glad to see your H2 in a new video I can't wait to have one of my own one day!!

The 6.0/4L80 is not a fast combination, that's for sure. But they will literally run at full load and full throttle for 300-400k miles or more. What's your check engine light on for? Could that be affecting the acceleration?

I have a 2003 Express 3500 ext with the same drivetrain. I tow my travel trailer, and have towed up to 9,500lbs. Pretty cool to see the same drivetrain working in the video. I wonder how the gearing differs? I agree that the transmission could use more gears.. But at 231,500 miles I'm happy with it.

Hi Andre, Your H2 desperately needs some mods! I have 2003 with now close to 400hp and 425lbsft, I have a 2800rpm high stall torque, along with 5.38 gears and my travel trailer flaps in the breeze behind me, I can get up to speed and even pass on the highway will towing a trailer. So you simply need some healthy upgrades!

Love it! I've got a 08 Hummer H2. I still have yet tow anything on it. Also, my air suspension compressor was giving out so I converted it to coil springs so I don't have to worry about having problems with it again in the future. If I have to tow anything with it, I'll just use a weight distribution hitch. Much safer that way anyway.

Towing my boat (22 foot 4500 - 5000 lbs) with my 03 H2...I just leave it in 3. I don't bother with the Tow Haul mode. I live in AZ, so in the summer you have to pay attention to the temps. But for a family of 5 packing all of our gear and the space we have inside while towing is awesome. Plus after we are done boating, we can go explore the offroad countryside. Can't find a better combo than that!

Awesome video i have the H2,07 like the capabilities.... And being here in Chicago its great, i offroad when i can

Wow I was surprised by 9.6 MPG, that’s actually pretty good considering what it is.

I intentionally avoided the 4 speed transmission when I was shopping for my Suburban HD. I have the LY6/6L90 setup. Towing my 7,000lbs travel trailer with my 7,000lbs truck loaded with family is much faster. Thank you for making me feel better about my purchase.

The question you have to ask yourself is would I rather have $60K extra in my bank account and this truck/boat combo or would I rather have $60K less in my bank account or more debt and have a new F150/F250 or similar to tow with.

Thanks for sharing your personal life with us.

more hummer videos awesome gotta love that hummer its a beast in its own class

Andre...... I like your video with the boat..... I've been a GM man since seventies.... I don't think the older 4 speeds had down shift Abilities in their tow haul mode. I think the tow haul worked holding the gear longer but no down shift ability... I may be wrong... Hey have a good day and be safe... Keep em coming !!!

I’m dying at that knee board clip. Love it.

Andre on the knee board! Yes🤘 rad dad award

I had a buddy with a 5.3 that had the same lethargic towing issues, and after a MAF cleaning and some new plugs, it woke back up.

4L80 shifts very nicely with a shift kit installed. The slow shifting was a notorious combination of wear 'n tear and GM trying to make the shifting realllllly smooth.

One of my dream cars is this with a LBZ Duramax swap

How bad would it be to shift manually and keep the revs higher? I'm sure it has a gear 1,2, and maybe even 3 option with overdrive. I do that in my underpowered honda sometimes if I need power on a hill or to pass.

That thing needs a supercharger! Love the videos.

The towing mileage was better than I anticipated, especially with that big V-8, 35" tires and a 4-speed automatic transmission. But I must admit that I was laughing out loud while watching Andre floor the throttle from a dead stop. How about an Ike Gauntlet run?

Did the check engine light come on?? Or was it already on during your acceleration?

Love this mini series!

Love my H2 which I have had for a long time now. Have about 170000 miles on it with a couple things to take care of but it's one of my daily drivers. If motor work is ever needed I'd like to put a 6.2 in there with maybe another trans. Used to have an 07 Escalade and I loved the power and decent economy it had due to more gears.

My 2006 H2 makes 10.5mpg towing a 4000pnd boat. True its Slow as slowly could be But once on the boat ramp it could take a tank out of the water . 14 years and 140k miles later I still love this truck An aftermarket transmission cooler is a must

Andre launches new channel, TFL Boat!

I tuned a 2500 HD Silverado, a 2002 and it made a considerable difference. I'm sure the guys at 5 Star Tuning could hook it up for you. Mine was nothing special...just a plug and play for $300 but it worked. I know it will help out that 6.0L a bunch. Anyway, love the video and love TFL so much! I remember when you only spoke Russian Andre. And read brake temperature haha. Love you guys

I agree with you I refer to any suv that's truck based as a truck aswell

That's the only thing I never did like was the all the time AWD. Id take the drive shaft out for the 4wd during the summer time. Give you little better fuel mileage to. Done it with my trail Blazer helped alot.

What is the best year model Hummer SUT to buy for towing?

Hi Andre. What gear ratio is in that truck? And maybe its time to check out why your Check Engine light is on.

Nice looking rigs!

The problem is you didn't change the axel gear ratio, when you upgraded the tires...are they 35s? If you goto 4.56s or 4.88s it brings everything right back to specs..

I like videos like this. I wonder what the tongue weight is. Nice to see the Weigh-Safe hitch.

Whats the specs on your wheels and tires? Looks good

What a beautiful truck.

What’s the time of this truck to 60 unladen?

My 2004 H2 6.0L has a aftermarket transmission cooler with Fan it really helps..... cost of $200 when the total max towing 6700 lbs H2 curb weight 6400 lbs That's alot of work

We still have our old H2 6.0. It has an electrical drawl though. It’ll kill a battery in a week if not started. Mechanically it’s been very reliable but SLOW is an understatement. Top speed towing a 6500 lbs boat in that truck was about 70 until you hit the TN hills and you’re lucky to go 50. I couldn’t make it from Memphis to Nashville on a tank of gas unloaded. That’s bad.

How many miles does the H2 have?

I remember when they came out, my friend and I looked at one a the GMC dealer and it was horrible. The interior had terrible seating in the rear, small cargo, horrible gas mileage. But it looked cool on the outside

Andre, I think it would be a great project to tune it or supercharge it! Maybe contact sloppy mechanics and get a turbo for it!

why does he say commercial grade 6.0 in every video. I always wondered why he says commercial grade and what he means by that. Is the 6.0 in the Hummer different then the other 6.0s? Does something internally make them superior? Thanks

Now you know what it’s like to drive a first gen CX-5. The only smile it gives me is when I floor it and it just gets louder, and not much else. I don’t think it could pull the skin off a pudding.

I have 2002 Trailblazer with the 4.2l straight 6 vortec and it's a bulletproof engine at 300k and still going.

ya know people give hummers crap but its a heck of a lot cheaper than a g-class and has more power and can fit more kit than a wrangler. it was the best cheap option the military could use. and if you do things similar to what military does (some off-roading and filling it with kit,maybe towing etc) i think itd be hard to do better for cheaper. the h2 and even the h3 isnt to bad just i think people bought it expecting a g-glass for cheap

what kind of radio is that?

The 4L60/80e were analog the prior generations. In my opinion, you gotta use it old school and drop gears. The 321 behind the D gives you engine breaking and the effect of holding gears longer like the tow haul mode does. I think could get the breaking and better speed from that same truck by running it in 3 or maybe 2 even.

Can I pull a 7,000 lb camper with an Hummer HUT(Truck Model yr 2006)?

Supercharge it!

Torque Management Andre is what kept the acceleration slow. My 5.3 Yukon XL accelerates faster while towing as TM is mostly removed.

More boat videos!!

I had a 2007 2500HD with the 6.6 gas. It was not a good pulling truck, the 6 speed trans. It was in the wrong gear.

What year is this

I was always amazed at how slow those H2s. You could get a fully loaded Suburban with the 5.3 and still be faster and get better mpg than the H2. But, the H2 is of course better off road and that combo of 6.0 and 4L80E will easily outlast a 5.3/4L60E Suburban.

could u remap the ecu ?

Ya my 08 H2 6.2 and 6 speed is definitely the better choice but its still a great power house for durability

Good Morning My Good Friends Of The Fast Lane Trucks & God Bless You All & All Of You're Whole Family Today From You're Good Friend Timbo White

nice moves on that kneeboard😁

Hey Guys. I love all your videos. But a have a HUGE request. Can you PLEASE. Do a tow test on a Chevy Express Van. I have a 2016 2500 passenger Van with the 6.0 and 6sp My goal is to tow a toy hauler travel trailer with a dry weight of 7300lbs I know the van is rated for 9800 But I would love to see you guys test the van I take your opinions and suggestions very serious

You need one of them Chinese eBay turbo kits. Then it will have 1300hp according to the internet. It's still a worthy competitor to modern off road trucks even if it's a bit slow on asphalt. Always love a good hummer!

Put a locker in the front and that thing is just a beast!

You give that thing a tune up?

You need to do an lbz duramax swap on it, then tune it, be the best truck you got

It’s not just a truck it’s a beast 😂

The 08-09 tow much better. The older trucks like the one you have were only rated for 6700lbs while the newer ones with the 6.2 and the 6 speed were rated for 8000lbs. It toes way better. The 4 speeds are just pathetic. Also did you have tow/haul mode enabled? I didn’t see it on. It makes a big difference.

It might be slow, But you look good !

I used to own a 03 Hummer and my newer 08 with the 6.2 is much faster. Plus the 6 speed helps with better fuel mileage. I average 15 mpg with the 08 whereas my 03 was getting 11mpg.

I'm a Ford guy but everytime Andre makes a video about his H2 it makes me want to buy one of these. I'm curious what everyone thinks about the smaller H3 models?

Your check engine light is on sir

Hey guys, I recently bought a Ram 1500 with a 3.21 axle ratio, can it be possible to upgrade to 3.92 axle ratio? And how around how much would it cost?

Test it on the Ike Gauntlet.

You're a mile above sea level and that H2 is heavy to begin with and with a trailer out back the 6.0 did pretty good considering its age.

When they built the hummer with the 6.0, they forsure overbuilt under powered the engine. Tunes, exhaust (high flow cats) will wake them up. beyond that, HCI (Heads, Cam Intake) with slightly larger injectors really wakes them up. Beyond that, custom turbo, superchargers easily give it 75-100hp. The 6.0L 366ci engine making only 325hp is way detuned. They do that for 2 reasons, 1 it runs on 87 pump gas, 2 detuning it makes them last forever. The transmission was never anything to brag about, but if rebuilt with better parts it's pretty dang strong. I always felt like it needed better diff gears, the gearing standard of 4.10 was good for 2003, but really needs to be like a 4.56 orif you want real grunt, 4.88 maybe on 35s. 4.88 is a must if you go 37 or larger. (if my math is right, 4.56 on 37's is the same ratio as 4.10s on 35s) But I feel like it needs 4.56's on 35s, 4.88's on 37s. It doesn't sound like much, but that diff gearing change to 4.56 on 35's would really wake it's towing up and acceleration and would help in in-city gas milage quite a bit by giving it that mechanical advantage. But it really seems like the stock 4.10 gear was a really bad choice by 2006/2007 it just wasn't enough and should of been changed by GM. What kills me is guys who run 37's on stock 4.10 diffs. LOL ouch.

Not the slowest ever. The H1 is the slowest ever :P

knee board is such an underrated water sport..

How old is this H2? Love my 3.2l 170 ps 4 zylinder Mitsubishi Pajero 2009 full loaded car 3.1t and trailer full loaded 3.5t 200 km highway and mountain roads are no problem and had over 280k km. but is old and have a "stupid" transmission can not down shift the most i hate and i need on this trip 12.8l Diesel on 100km and is much quicker and not so noisy

True workhorse!

9:15 word of advice, if you’re going to use your H2 to tow anything, upgrade your cooling system

So no Ike gauntlet?

GM should just give you a LS 2. Geez, come on GM, this guy is sooo loyal ! #longtimesub. Peacefrom510 .

Wanna see how Tesla will do trying pull it 0-60 only. Yes I know it over the rated weight but there was a video of Tesla pulling a plane. By how much will it beat Hummers time 🤔 (try also other cars for comparison)

Oh what a bummer - Andre bought a Hummer. Haha.

That old 6.0 did well

My 2012 Silverado 2500 gets the same mpg when towing

Was that a roadkill/boatkill reference???🤔🤔

You know Andre, I was going to give you a big kudos and say that the performance does not have to be fast or very efficient as long as it works. Then I realized for your safety, it might be advisable to use something that can get out of its own way for merging and what have you. For a GMC product, you are fortunate it still can do anything IMO. lol Thanks for sharing your personal clips of boating and what have you. :)

That's why I like my 08... 6.2 with the 6 speed was way better.

I NEED that boat...in a serious effin’ way.

35 seconds?! Man that’s scary.

My buddy has the same truck after he put a bully dog on it it would get out of its own way. My semi with 30k pounds in the box will still walk off on it though

I have the unicorn of all hummers. a 2010 H3T alpha with the offroad package (low range transfer case and locking difs) she is much quicker then that!

Why is everyone advertising the Hummer H2? It's even got to the Snowrunner video game. Does it mean the GMC Hummer is gonne be closer to H2 in proportions than to H1? If so... that sucks

"How to drag a 1 minute video into 10:07... TFLT or FML?

Towing is not meant to be a speed race! It's supposed to be smooth, cautious, and respectful to the weight your hauling...not to mention the distance it takes to safely stop in an emergency. You could literally haul that same big boat with a V-6 powered S-10 if you took your time, manually shifted out your gears and didn't stress your vehicle.
