- I spotted this Hummer H2 at the SEMA show in Las Vegas a while back. It claims to get 100 mpg with bolt on technology.
I am intrigued by this technology because I want a fuel efficient hybrid but I dont want to by a Prius or a Tesla...I want a 4x4 truck!!! With this technology it looks like I can finally have a hybrid 4x4 truck.
Here is a some info from their website...

The Patented Goodwin Assist is a revolutionary new technology for converting Hummers into highly fuel efficient plug in hybrids. The Goodwin Assist is focused squarely on bang for the buck proposition of maximizing fuel savings with minimal capital investment resulting in the shortest ROI.
Benefits: 18-24 Months ROI, 60% Fuel Cost Reduction, 60% Less Emissions
The Goodwin Assist provides 80% of the financial benefits of other solutions at 20% of the cost. Typical drive trains, transmissions and internal combustion engines are highly inefficient. Goodwin Assist components include a state of the art electric motor, system controller, and a modular lithium ion battery pack...which can be plugged into any standard 1-10 outlet, to store inexpensive power from the grid.
The Goodwin Assist applies that stored energy via the electric motor to assist the internal combustion engine when it is most inefficient, significantly reducing workload of the engine and the use of fossil fuel. This duel-fuel approach allows vehicles to take advantage of the great power delivered at the equivalent of $0.75 per gallon.
The Goodwin Assist reads the engines performance and increases the assist when the internal combustion engine will benefit most from a fuel saving perspective such as frequent starts and stops.
The Goodwin Assist requires no EPA approval or crash testing, and is comprised mostly of approved off the shelf components from industry leading automotive providers. Once converted, these vehicles see their fuel cost is cut in half or more. The conversion process is simple, inexpensive and requires no major overhaul of the vehicle.
Goodwin Assist's unique engineering allows for uninterrupted driving on the unlikely event of a system or component failure, making The Patented Goodwin Assist the only alternative for critical vehicle operation. This development has seen multiple generations of prototype vehicles with significant efforts placed on safety, components testing and systems engineering .
Untold hours of refinement and testing as well as enough miles driven across the United States many times over has allowed us to prove The Goodwin Assist system. The vehicles have exceed over 100 MPG with a simple to install retrofit solution.In addition of course is a performance mode. This mode allows the end user to maximize the performance benefit of the electric motors power. It becomes a reverse supercharger. Another feature of the system is regenerative braking. In this mode the Goodwin Assist becomes a generator for those critical times were electricity is at a premium.
I pulled 30 cars through our neighborhood in my stock height h2 with duratrac tires when it iced. Hills and all. With no trouble. Big trucks and jeeps had hell. I motored along with no issues. Offroad it was amazing. It was also a smooth plush ride. Only issue was replacing a hub.
I'm more interested in the anti-stick figure family decal, personally. ;)
lol
H2s are awesome af thanks
I had my H2 converted over to a propane dual fuel system, it starts on gas and when the engine is warmed up it switches over to run on propane. My fill cost is 0.47¢/litre so about $40 a tank and I get about 375KM. Propane has a higher octane rating than gasoline (104 to 112, compared with 87 to 92 for gasoline) and potentially more horsepower, but its lower British thermal unit (Btu) rating per gallon results in lower fuel economy. However, the price per litre can quickly offset the lower fuel economy.
The potential for lower maintenance costs are one reason behind propane's popularity for high-mileage vehicles. Propane's high octane rating, combined with its low-carbon and low oil-contamination characteristics, has resulted in improved engine life compared to conventional gasoline engines. Because the fuel's mixture (propane and air) is completely gaseous when entering the engine's combustion chamber-and does not require an enriched fuel mixture for combustion such as with many liquid fuels-cold start problems can often be reduced.
I'm interested in this propane conversion. How much was it?
I'd like to consider running the hybrid electric system along with the lpg/propane, be equivalent to 100+mpg
@@dand6298 biggest costs are the tank and fitting. I run a 5 cylinder volvo with lpg conversion, the kits for that can be £800 to £1500.
Quickly offset the cost though, I've done 10k this year predominantly on gas/LPG which has cut between 1/2&2/3 off the bill
I would need to see real world results, but I appreciate the innovation.
Thats a very Great Conversion for sure even if you got 50mpg it would be great , Gerry .
I agree. I'd be happy to get 50mph! now if they can make it reasonably priced and rock solid reliable....I'm all in.
There have been a few companies that have come up with bolt-on hybrid technologies. It's basically a motor / generator that gets put in as a belt drive auxillary device, just like your alternator or AC unit, with a controller that interfaces with your ECU, and a big bank of batteries that gets stashed somewhere. I've never heard of one that acted as a true plug-in (able to drive without the engine running), but maybe these guys have some new tricks. I'd love to find one that could bolt on to my recently acquired 300SD Benz that runs on veggie oil... that would make a hell of a fuel inflation fighter!
I remember seeing truck that ran on wood chips using gasification. it's not quite green but the thought of being able to drive where ever there is Wood is still interesting from a Prepper point of view. combine gasification with 100mpg hybrid and you might be able to drive across the country with just a few campfire logs?
Engineer775 has a few gassifiers on his channel... some even work by gasifying plastic. It's labor-intensive, but it works. I'm betting the H2 gets that 100mpg about ten miles at a time... then sitting for a twelve hour charge.. then another ten miles... just a hunch. A smaller gassifier feeding a smaller engine driving a genny and then an electric vehicle might work as well... a sort of homebrew series hybrid. It's all in how hard you want to work for it. There are no free rides or magic bullets. We are all slaves to the laws of thermodynamics and physics.
I believe Jeep are working on a similar tech for the wrangler. It uses a electric motor to charge a battery pack while driving then, when stopping it stops charging the battery. When you start off it uses the battery power to help the Internal Combustion Engine to spin up quicker effectively adding HP to the ICE.
The first Honda insight pioneered this technology back in 2000.
Very interesting. Would like to find out if it has been tested or proven to work and get that type of mileage
I know it’s your opinion but Hummers are actually cool you’re one of a few people that dislike them. But I think they’re really nice trucks and if you modify them right they are really good for offloading and when I mean modify I mean modifying the suspension system and it is a really good off-road truck.
Depending on the cost I'd be more interested in a bolt on system then the via motors system
me too
I can see a use of the bolt on, on a bobbed 5 ton ;)
Better than GLP, BTW that H2 looks amazing, at some point is maybe better this way?? The real problem is engine sound, and authonomy
I was hoping u could do more pre-runner related trucks. Like a fully built (long travel suspension) set up tacoma or tundra.
I'll put that on my list for the offroad expo in California the next sema show.
I'd be interested in learning more about the modifications and which vehicles are available for this mod. For new vehicles, it appears (and maybe it's just me) that the only manufacturer doing large vehicles anymore is GM with the Suburban which they don't offer from the factory with diesel anymore. So we are almost always looking for franken-rigs. e.g. putting cummins into suburban, or some other combination of mixed manufactured parts. Yes I am interested, just not in the hummer h2 version. That rig is a terrible daily driver.
I agree. I'd like to bolt this technology onto a new Toyota Tundra....not an H2.
H line conversions who does the install of this kit has a video that says this kit is designed for all GM LS engines for now.
they are also working on a hybrid design that bolts on after the transmission so it can run the vehicle in an emergency in case the gas motor takes a hit. I think it's being developed for the military.
How do you figure an H2 is horrible off road? Locking transfer case locking rear diff 4.10 gears stock near 400HP and Tq stock 35” BFGs fits up to a 37-12.50 stock without height adjustment solid boxed framing no twisting the chassis AWD im not seeing the down falls here sure it has its limits just like any wheeler but stock it beats 90% of anything out there just my personal opinion of course to each their own obviously oh and dont forget about clearances approach and departure decent break over as well stock obviously rigs with lifts and larger tires that becomes irrelevant but as is hmmm🤔
True...I dont know for sure it's bad off road since I dont own one. Its probably not as bad as you would think. I'm just thinking about it's insane weight and size coupled with its IFS. I'd own one if it had this hybrid kit and it actually performed as advertised.
Nice, please do a full review on the technology employed...maybe get an interview with the manufacturer. 👍
I wanted to do a full interview but there wasn't anybody around to talk to....
+mixflip cool,no worries bro! 👍
because its connected to the motor yes better mileage but you run outa fuel you still stuck. electric motors connected to wheels or some other part of the drive train and a solar panel on the roof, I kinda like the idea that if you run out of fuel just camp out have a cold one and wait for a full charge
Have you ever been offroad
Something new for me to look into.
thanks for watching
If it's affordable. Somewhat easy to install and reliable. I would love to throw it on my Chevy V8.
me too.
Got a Hemi v8 Jeep Commander, would be nice to see a demo.
me too.
if it works wells then it is worth it. I wonder how the system works
it's basically an electric supercharger with regenerative braking. the electric motor is connected to the crank shaft with a 2 inch Kevlar belt and helps the pistons turn the crankshaft. kinda like 2 people carrying a Jerry can of fuel vs just one person....so to speak.
I hope I got that right?
if it makes the same power i'd buy it
it says it bumps up the power as well.
100 mpg? That's literally impossible on a Hummer H2 unless you are running a different kind of fuel and only driving 15 mph. LOL
My H2 2005 8km/L
100L/800km
Would like to see it in action
me too
Yeeeeeah.... you lost me at Prius....
how much will this cost? when will it be available for sale? is this actually real? Because I have a hummer h2
28k
Whats the cost to plug it in ???
any real world testing?
How would you get one?
If Hummer h2's are so bad off road, why do see so many in Moab Utah climbing hills, just sayin
100 mpg on a hummer h2 no way ,, how
And what truck do u drive
I used to drive a gmc Yukon, then a chevy Tahoe, then a ford 150 crew cab....but now I just drive a tiny gas friendly hyundai tucson lol.
my '03 ram 1500 with a 5.7 hemi averages 10.5 mpg with the more common being around 7.5-8 around these parts due to hills. If im lucky, i get 12 highway.
so you could really use this technology.
ontarioknivesNS7 bullshit, i had one and got 368 miles on a full tank on the highway and only spent about 120 on gas from houston tx to denver co.. how slow are you driving..
Don't appreciate your opinion of the H2. Obviously you have never owned one. However the electric motor upgrade is interesting.
Sorry you dont appreciate my opinion. It's a very common opinion of the hummer H2 btw. Everyone has the right to their opinions though. I dont need to own something just to have an opinion.
I also dont have the Coronavirus...yet my opinion is.....I dont like the Coronavirus.
any h3 upgrades
not yet
bolt on an electric motor, battery, controller. with 100 mpg you won't have 300 HP . if you want 300 HP it will still be 15 mpg. I hope I'm wrong but I see no miracles here. I gave you a thumbs up so if you get more info I find it interesting. Having a hydrogen generator and filling up with salt water may be better.
hydrogen would be nice. heck....I'd take a wood burning gasification hybrid at this point. have you seen those? there is a truck than runs on wood chips but of course the government won't make it street legal. go figure.
so the guy just drives the truck on his farm.
i would rather keep it gas than putting an hybrid engine because with an hybrid tour suv does not have power
It works with the gas engine so it has a lot more power.
Your link ( www.goodwinassist.com ) does NOT work.
Seems pretty snake oily to me.
Throw in a Golden Gate for free and you've got a deal.
check out VIA motors. they make a 100mpg electric chevy Silverado that is being tested still. this technology is coming. I pray it's not snake oil....I want a big truck with prius gas mileage.
God you guys are stupid!! This video is STUPID.... That thing is awesome!! How about do some research before you bash something
Bob Lutz (former Vp at General Motors) started via motors and claims 103 mpg. He’s pretty credible.
I get 18 city and 20 highway in my h2 don't know what you were reading
lol I get 7 average. But I need to change my exhaust I put on a magnaflow muffler and it's not big enough
Scotish nightmare I get 12.1
when you floor it, is it like 3 mpg?
i like hummer h2 just because of how obnoxiously big they are, i think they're cool.
I own H1 and H2 and a Jeep Rubicon and wife has a Jeep Liberty ( we live in northern 🇨🇦) couldn’t live without a truck or 4by 4 up here...
I laugh every time someone asks me about the gas mileage..I hate to break it to all the haters but if you own any full size pickup or a Jeep your gas mileage is about the same as what my H2 gets...
Also if I have to go to work in the bush camp I never take my Jeeps ,they have left me stranded too many times (Crank and cam Position Sensors failed twice,fuel pump once etc...)
Not one of my Hummers have left me stranded..the 6.0L Vortex is bullet proof ..
My Hummers have also rescued/towed out a few logging machines stuck in mud/ice...
Last point for dependable it’s been
-36 Celsius here most of winter so far..(that’s -32.8 degree Fahrenheit for you yanks) even after sitting for 2-3weeks frozen solid (went to Hawaii) when I got back my wife’s Jeep Liberty needed a boast, and the Rubicon needed Quick-start ...(yes both Jeeps had block heaters on timers)
Both the H1 and H2 fired right up...
So I laugh every time someone who probably doesn’t even own a Hummer tells me they are pieces of Shit ...
I owned both new from factory..except for oil & spark plugs & brake pads( all normal wear) I haven’t had to spend a dime ... that’s 12 years of dependability...I spray both Hummers with the used oil underneath (frame etc) it keeps them rust free...
I will post another update in 10 years with pretty much the same results...
Cheers from HudsonBay,Ontario 🇨🇦
need more data, could be some mathematical loophole. like it it'll gets 20 miles/charge
check out their link I provided below the video. maybe there is more info there?
also check out videos from H line conversions. they do the actual install of the Goodwin Assist hybrid system.
Sounds like a scam, but be more than glad to be proven wrong. Even if this does work, it’s new. It’s not proven system and who knows what the expense is going to be.
It's bull shit. You'd have to somehow have an electric trans. Then you'd have to have the battery connected to an electric motor. Then you'd need a synergy system to tell it when to charge and when to drive and when to pick in the hummer.
this product is full of shit
I call BS.
Hahaha they are out of business scam fake
NO!
How about YOU come up with an informative video with FACTS that we can look at and not some "ooh, look at that" piece of crap!
Koito rob how about you go to SEMA and do your own homework. I was just walking by and thought it was interesting. I put a clickable link to their website for "YOU" to do your own due diligence. And btw if there was a rep standing there I would have gotten you a full detailed interview. Free of charge mind you. I'm ok with giving you free info by going to to these shows but if you want to learn more you are going to have to do your own work.
