2022 GMC Hummer EV SUT: What We Know So Far

In an amazing twist of fate, General Motors' gas-guzzling middle-finger-flying Hummer brand, discontinued in 2010, is poised to make a comeback for 2022 as an all-electric sub-brand of GMC. We know very little about the GMC Hummer EV SUT pickup truck so far. But we do know that it will offer 1000 horsepower and GMC claims it's capable of blasting from zero to 60 mph in just 3.0 seconds. Pickup trucks are clearly the next frontier for electric vehicles, as potential rivals from upstarts such as Rivian, Bollinger, and Tesla—as well as entrenched truckmakers such as Ford—are preparing their own entries in this emerging segment. We'll know more soon, as GMC plans to unveil the Hummer EV SUT and it's novel "crab mode" on October 20th.

We aren't even sure yet what kind of standard or optional features will be available or what price the Hummer EV SUT will command. We'll find out much more about the new pickup truck as it inches closer to production.

Engine, Transmission, and Performance We've heard that the Hummer EV SUT will be available with one, two, or three electric motors. The single unit suggests a rear-drive model while the two- and three-motor setups indicate two different all-wheel-drive potencies—and punchy acceleration. So punchy, in fact, that GMC is claiming a 3.0-second zero-to-60-mph time for the truck. Every additional electric motor should provide increasing payload or towing capacities. GMC claims that the Hummer EV SUT will make 1000 horsepower and a whopping 11,500 lb-ft of torque. While we take issue with how that misleading torque number is calculated, it should have massive pulling power regardless.

Only 23% of the entire grid is coal. In states such as Texas we get well over 50% from clean burning natural gas and another 18% from clean nuclear and there are times where the entire Texas grid is 100% wind powered it happens a few times a year when the wind kicks up in west Texas all other power plants shut down and curtail for wind and solar by law except for the two nuclear plants they ramp down slowly or steam dump while maintaining the frequency control of the ERCOT grid. I’m an energy consultant. More than 75% of the US grid power has an emissions output per Gigajoule an order of magnitude less than an internal combustion engine. This says nothing of the fact that a electric vehicle is three to four times more efficient with using those joules to move mass over distance. A Tesla model S uses 250 watt hours to go one mile that is the equivalent of 137.6 miles per gallon on a higher heating value of 34.4 kilowatts per gallon of octane. E10 has less so I already gave the gasoline an advantage. No internal combustion engine powered vehicle of comparable size can touch 130+ mpge. 250 watt hours is also the round trip energy useage after being stored in the battery packs. Physics favors a second law process such as electricity and chemical storage over a third law heat driven process cannot cheat Isaac Newton. Natural gas combined cycle plants have a net carnot efficiency of over 60% and the grid loss are 3_5% the gas well to the wheels emissions of Nox, Sox, particulates, and carbon soot for a GTCC plant vs the tail pipe of a car is a joke to even compare them the scrubbers on the gas turbines are again much more effective. Nuclear releases none of those emissions nor does hydro, wind, or solar.

One KG of uranium fuel will generate 45 megawatt days of power...45MwD*24hr*1000kw=1,080,000 kWh in a EV that means 1,080,000×4 miles per kWh = 4,320,000 miles from ONE kg of uranium fuel. Or 432 miles for 10000 electric vehicles which works out to 62 miles per day over 7 days. Only few people commute more than 50 miles round trip per day. In fact 85% of all Americans commute less than 40 miles round trip per day. Food for thought one KG of 4.5% low enrichment uranium costs $1200 in 2020 dollars. In btu equivalent of the higher heating value to octane its the equivalent of 3.82 CENTS per gallon of gasoline.

$1200 kgLeu / (45MwD kg * 24hr * 1000Kw ) * 34.4 kWh gallon gas equivalent HHV = $ 0.0382222222 x 100 to convert to cents = 3.82 cents per gallon.

Nuclear energy plus electric vehicles means gasoline at a raw energy cost of 4 cents a gallon there’s 42 US gallon to an international barrel of oil so nuclear power is equal to oil at $1.62 Bbl nothing can touch that cost wise in raw fuel costs alone. Adding in waste disposal by federal law the fee at 0.1 US cent per kWh doesn’t change it much.

Electric vehicles and nuclear power are the future that much is certain as soon as battery technology hits $100kWh in storage costs the total cost per mile over the 200000 mile lifespan of the vehicle is 3 cents per mile in pack costs with access to energy at retail of 8 cents per kWh is 2 cents per mile in energy costs. 5 cent per mile in energy plus storage is equal to $1.5 gal of octane at 30 mpg which a large 4 door sedan equal in size and weight to a model S should average.

Analysis shows Tesla has crossed $127 $/kwh and is heading to $100 soon. They warranty their packs for 8 years unlimited miles and commercial Teslas have already gone 500,000 miles plus on their current pack technology. The 2022 model S and 3 both will have million mile packs targeted specifically at commercial ride share vehicles and transport.
