    Are gas or Diesel engines designed to run at their max output for long periods of time? Some are, right? So, arguably, itís a matter of building the system to handle the load itís likely to see Iíd think

    And yes, it's going to be a wealthy person's toy. Figure the sticker price north of 100k, a useful battery life of perhaps 150k miles (at which point your 400-mile battery gives you 200 or less miles of range) and a battery replacement cost of 40-50% of the new vehicle cost. They would also be smart to allow it to charge off of Tesla's Supercharger stations, because a 400 mile-range battery is going to be a lot of KW/h, and even a 50A 240 outlet ain't gonna charge it overnight.

    I seriously doubt you will see one on any serious trail. The scenic trails at Moab? Sure. But a new owner ain't gonna risk a dent or scratch on this pricey unit. However, if someone does and I'm around, I will be more than happy to get them un-stuck or tow 'em out to the road where they can be loaded up on a flatbed
    I watched the H1 owners dis the H2 when it came out. I then had to listen to H1 and H2 owners out down the H3 when it came out.
    All 3 turned out to be great off-road. Each in their own way. And reach one head their failings.
    I'll at least give the GMC Hummer a chance.

    Have you seen the size of a 1000HP continuous-duty electric motor? The "light" ones weigh over 7000lbs. The heavier induction-type are typically north of 9000lbs. Water cooling can reduce the size somewhat, as does using permanent magnets, but you're still talking about a very large, heavy motor.

    I agree that a 1000HP supercharged engine in a Hummer-sized vehicle is not going to be continuous-duty either. That said, a new 700HP Corvette can sustain it's full output for many minutes, at least long enough to reach and, for a time, hold the car's top speed. The primary limitation is the cooling system. It's hard to fit a radiator capable of dissipating 1.7 million btu/h in a Corvette,

    I remember when the ZR-1 Corvette powered by the Mercury Marine LT5 engine (375HP), and a standard Corvette engineers modified a regular small-block powered Corvette's engine with off-the-shelf parts to make 350HP, both ran 24 hours flat out on a 2-1/2 mile track with stops only to re-fuel. If those cars were electric, a 350HP-375HP electric motor capable of running continuously would weigh four times what those gasoline engines weigh. I won't even mention the size of the battery pack needed to sustain that output for thirty minutes, which is the approximate length of time a 350-375HP engine running flat out can run on a 15-20 gallon gas tank in a Corvette.

    I'm not concerned about it's capability or performance. I have concerns about it's true utility as something other than a toy for the well-heeled and a vehicle to appease the windmill huggers.

    I do have the same recommendations for this vehicle as that to anyone wanting a Tesla or any other EV: LEASE IT! You don't want to be stuck trying to unload it after half the battery capacity is gone and any potential buyer (or dealer for a trade-in) realizes a new battery pack is 40% of the cost of a new vehicle of the same model

    Whether the new HummerEV will be designed to be able to withstand the stresses it encounters as owners use it, remains to be seen. I happen to think there is a good chance it will work just fine. Your comments about EV's loss of battery capacity seem exaggerated. I say this based on the statistics I have seen regarding Teslas. Do they lose battery capacity over time? Yes. If memory serves me correctly, about 5% in the first 3 years, then less in the years following. Tesla has a pretty substantial warranty on their battery packs: 8 years or 120000 miles with retention of 70% or better battery capacity remaining. Which gas / Diesel engine manufacturers offer that kind of warranty?

    BTW: I *do* lease my Tesla. Not because I'm particularly concerned about loss of battery capacity, but because the EV market looks like it will be VERY different in 3 years. I believe there will be many many more EV's on the market by that time, so I am protecting myself from any crazy losses of value by leasing.

    It depends on the climate and usage. Hot climates like AZ wear the batteries out faster. Deeper discharging before recharging wears the batteries out faster. Higher charge levels wear the batteries out faster. Use of the Supercharger wears the batteries out much, MUCH faster!

    I say this based on the statistics I have seen regarding Teslas. Do they lose battery capacity over time? Yes. If memory serves me correctly, about 5% in the first 3 years, then less in the years following.
    Again, that depends on many factors. That figure would be the most optimistic scenario.

    They don't have to. Fuel tanks don't shrink in size as they age. The fuel tank in my Blazer holds the same 31 gallons of fuel as it did when it rolled off the assembly line in 1991. How many EV's will still be on the road in 29 years?



    BTW: I *do* lease my Tesla. Not because I'm particularly concerned about loss of battery capacity, but because the EV market looks like it will be VERY different in 3 years. I believe there will be many many more EV's on the market by that time, so I am protecting myself from any crazy losses of value by leasing.
    You make one of my points about EVs. Because their "fuel tank" shrinks with age and use, they will depreciate much more rapidly. When the battery reaches less than 50%, and definitely by the 30% mark, the vehicle will be scrap because the batteries are far too expensive to replace compared to the vehicle's residual value.

    That brings me to another problem; recycleability. The batteries are only partially recycleable. The motors are probably nearly 100% recycleable (not sure about the permanent magnets). So is the copper or aluminum wiring. However, the electronics are not only not recycleable, but they are persistent toxic waste. One of the most polluted, toxic cities in China is the one where much of the world's dead electronics go to be "recycled". They extract the meager (but profitable) precious metals and junk the rest. Because EV's are impacted by weight more than vehicles powered by ICE's, more lightweight composites and filled plastics are used, both of which are virtually non-recycleable, don't have much use as ground filler material, don't biodegrade, and can only be incinerated in incinerators with expensive filtration to remove the toxic compounds generated. There are also a lot of non-filled plastics used that are also not either economically or practically/usefully recycleable. Basically, they are bulk waste with varying levels of toxicity, just like the scrap electronics.

    By contrast, steel and aluminum are EXTREMELY recycleable. Modern cars all use lots of non-recycleable composites and plastics, but those powered by ICE's use less than their electric counterparts, on average. Composite and plastic body panels might be good for dent resistance, but aluminum is just as light and can be recycled over and over. I will avoid my tirade on the trend/fad of equipping cars with more and more electronic infotainment junk that becomes more persistent solid waste when the disposable car they are used in is scrapped at the end of it's life. Also, ironically, despite the toxicity of lead, the lead-acid batteries commonly used for SLI (starting, lighting, ignition) are recycled with virtually no loss. They are the most completely recycled item in common use. Not just the lead plates and conductors, but the polyethylene case and separators are also highly recycleable.

    When discussing EV's, you have to consider so much more than "how many miles of gasoline equivalent does it get" and whether or not it emits CO2 from a tailpipe. They are far from being more environmentally and economically benign vs their ICE counterpart. And again, if the ICE vehicle is powered by renewable biofuels and manufactured with more recycleable materials, and considering ICE vehicles require very little in the way of rare expensive elements for their manufacture, then the environmental and economic aspects of EV's gets even worse.

    Finally, despite appearances, I am not "anti-EV" per se. I AM anti-EV using the current technology. I see it as hopelessly wasteful, and being touted as "environmentally friendly", "sustainable", and "emitting no evil global-warming-causing greenhouse gases" when in reality they are actually doing more environmental harm than ICE powered vehicles. They are an anti-solution to a non-existent problem. If you like your EV, like the performance, quietness, or whatever other perceived positive attribute, that is great, and that is the free market at work. They're being made, and if you like one and can afford it you can, and should, be allowed to own one. But when people start touting their "environmentally friendly" EVs and saying we need to eliminate ICE vehicles and replace them with current EV technology, that is where I have a big problem. I know nobody in this thread has proposed such a thing, but a LOT of global-warming evangelists do, and so do some EV manufacturers who spend millions lobbying in Washington for more laws and rules favorable to EVs. Even if EV's were truly superior to ICEV's environmentally I would be against it, but when it's based on lies solely to boost the profitability of the EV market then that makes it criminal.

    Here is a source which points to actual, real world data on this topic. Not a scenario, not an assumption, but actual, real owner reported data: https://electrek.co/2018/04/14/tesla...radation-data/. The headline summarizes the data as: "Less than 10% degradation after 160000 miles".

    You say "IF". *ARE* most gas / diesel vehicles actually powered by biofuels? *ARE* they manufactures by more recyclable materials?

    I recall reading several articles where they estimate 6-8 years for an electric vehicle to break even with gasoline counterparts, and thats mainly due to the fact manufacturing an electric vehicle produces alot of emissions initially!
    However, one advantage of electric vehicles is that you can use renewable energy sources to charge them (solar/wind) which would help drop that estimate while a gas powered vehicle cant.
    Keep in mind, economies of scale will eventually drop all those numbers.

    I know that in my business we do quite a bit of recycling. To meet some of the green building codes we have to recycle certain percentages of the material ( waste ) used in the construction of the project and use certain recycled materials in building the project. Many of the recyclers don't want paper. certain types of plastics, Styrofoam, etc because there is no money in recycling those products. Some will take paper even though they lose money recycling it.

    I will post my opinion.
    I have Tesla X 90D since sept 2016 (first gen)

    As a city runaround itís great. Wife mostly shuttles kids around.
    Quick as my old M6 (2007)

    Battery (my) has 8 year/unlimited mileage and being first gen free Superchargers

    Range depends on road conditions
    (hills add ~10/20% power use),
    weather ( cold ~up to 40% depending on difference between ambient temp and your T* setting)
    A/c uses quite less juice

    Prices on my model (100D) came down a lot last year~30%
    And it gained true Autopilot
    My partner got one for his wife end of last year and car actually drove him home without driver input ~30 mil ( freeways, streets and all)
    ( traffic signals update wasnít released yet, so it was seeing red light but didnít stop - itís being released later this year due to our socialist state )

    48amp home charger chargers ~32 mil/hour and u only charge 80% for dally driving
    I know 70 or maybe 100amp is available on certain models.

    Price wise
    Wifeís old car wasí08 GL 450 and we paid ~56k new back then

    Hew GL AMG was coming up to ~140k, so it was very similar in$$$

    $$ saving are modest for ~10k mil a year we save $3/4 k VS gas GL ( not included maintenance like tires, brakes ets)

    So in conclusion EVs like Tesla are great as city car ( rest of them are not worth looking at)
    But I donít see it doing any real long distance/ off-road use any time soon .

    I own a Tesla Model 3; Dual Motor Long Range model to be specific. Itís the wifeís daily commuter, though we love it so much we drive it everywhere all the time. Itís just an incredible vehicle. We purchased it when the Honda Fit became too worn out and it was time for a new commuter. The Model 3 had everything on the wish list, it blew away every other car we drove and compared it to, and it was different. We like different. Same reason I have owned my H3T for the last 9 years; I have only seen one other in person, ever, here in the southeast. That is also the reason I don't see this new Hummer EV being anything special. I watched the commercials, pausing and re-watching, really taking notice of the shape of the front, hood, fenders, hoping to get an idea of what this thing was going to look like. After studying it, from the front at least, it appears to be your standard GMC Sierra pickup with a shiny Hummer influenced grill. Nothing special. I don't think I would be interested no matter how it is powered. I really dislike the looks of pickup offerings today. They are so boring.

    As for being electric, that in itself wouldn't bother me. Certainly it wonít be a good fit for everyone. The range looks to be good though with an estimated 400 miles. That would work for me as it wouldnít be our road-trip vehicle. Which brings up the major point of consideration; if youíre looking at an EV purchase, I suggest you really educate yourself on the charging infrastructure in the part of the country where you live, and know that infrastructure's capabilities and shortcomings. If youíre just running the kids around town or driving to work and back, that is one thing. I mean, our Tesla charges at home while I'm sleeping, and I wake up every day with 300 miles of range for the daily commute; more than adequate. On a long road trip though, charge time will make or break your experience and there is a method to getting the most efficient charging session. Our Model 3 has a range of 328 miles on a full charge and we drive it all over, but I'm not sure I would want to do that if I didn't have access to Tesla's Supercharging network. I would not want to drive a 900 mile round-trip relying solely on commercial EV charging stations. That would be painful. Their charge rate is just too slow, and that is what you would be dealing with if you purchased a Hummer EV and was not charging at home. Right now, our long distance trips average 15 minutes charging for every 200 miles driven, so we would get a 15 minute pee/drink/snack/stretch break about every 3 hours of driving. With kids in the car, we can't make it more than 3 hours without stopping anyway, so it works. Charging time would be nearly double using commercial charging stations, and there are not that many of them. You could find yourself having to sit there and get a full charge, however long it took, just to be able to make it to the next one. The Supercharging network makes EV possible regardless of your vehicleís role, and the Supercharging network is only available to Tesla owners (currently). Just food for thought.

    However, letís say you have a Hummer EV and you pull your camper to the beach for a week vaca. Itís a 300 mile trip, so plenty of range to get there. Once your there and setup, just plug-up your Hummer to your campsiteís 30amp RV plug and enjoy the free gasÖ.I mean free juice. Good to go. There is always a way to make it work that is not as much an inconvenience as you would think.
