GM's new 5.3L V8 EcoTec engine, left, boosts fuel efficiency by using cylinder deactivation to act as a four-cylinder engine at light loads. Ford's 3.5L EcoBoost engine, right, boosts performance by using twin-turbocharger technology to create a more dense mix of air and fuel in each cylinder. (Source: GMC, left; Ford Motor Co., right)
So your response is that our dysfunctional, known to be narcissistic, government, run by "greenies." Chooses to force the military to buy tech that doesn't work? I refer you to history and again facts. How many of these "trucks" are deployed into and or functioning as, actual battle support? Huh? Answer...NONE! Have you read your own numbers? These are not even the minimum sustained requirements for daily use on any farm! And you don't even address the fact that you'll have to own at least two or three of these. Why? Because they take so long to charge that you'llneed the extras in order to have ONE ready to use. The suggestion that any current battery powered truck can be used for logistical military ops us patently insanity! On the others....how many of these are actually in use? Not many. Why? Because they don't even meet the conservative specs that they publish!
Electric vehicles may be the future, but they are not quite ready for general use. Electric motors deliver plenty of torque and are more compact that ICEs. With computer control, we can manage the torque output and mimic the output of virtually any ICE. Power isn't the problem. Where electric vehicles lag behind ICEs is in working range and refuel/recharge time. Battery weight is also a factor, but that is becoming less of an issue due to new lighter weight materials and new batteries with higher power densities. Limited range confines current electric vehicles to relatively small areas. EVs may be suitable for urban commutes and short-range delivery runs, but most buyers need flexible vehicles that can travel more than 150 to 300 miles in a day. Battery recharge time has improved greatly, but still lags behind refueling time for ICEs. That will likely never change, but perhaps the gap can be closed enough that the difference is not significant enough to matter. Until then, EVs will remain a very small part of total vehicles sales and will continue to require subsidies to reduce manufacturing losses.
The only "blabbing nonsense" and "biased emotionally based posts" are coming from your brain. Stop your single boiling neuron and find the facts, Read...

The Newton all-electric truck delivers a top speed of 55 mph (88km/h), offers a range of 50 to 150 miles (65-190km) on a single charge and a payload of over 16,000 pounds (7,250kg). It operates at peak effectiveness in urban applications that demand heavy 'stop-and-go' driving. A single overnight charge provides more than enough range for most urban delivery routes. Smith vehicles feature the latest in Lithium-ion battery cell technology, power management and direct drive trains.
Being the U.S. Marines Corps one of their users... ..." The U.S. Marines Corps has deployed Smith Newton all-electric trucks at Camp Pendleton, California, the Corps' largest West Coast training facility and home of the First Marine Expeditionary Force.
The U.S. Marines Corps is the first military organization to incorporate Newton into its fleet – and the first to purchase Newton trucks through the Government Services Administration (GSA) schedule. GSA Automotive is responsible for procuring more than $1 billion in vehicles and automotive services each year.

So what about the Tesla EV's? and the tricks pulled by a few guys with some brains like this guy that made the Wrightspeed 150 mi range and it beats the crap out of Ferraris, Porsches and NASCAR ICE's
And what about an average guy thinkering in his garage and getting an old Datsun to beat the X%^@#$ og some "powerful" Corvettes and BMW's gas cars

All this makes me think that there is something OBSCURELY WRONG with the Detroit car industry and BIG OIL when a few garage tinkering guys can pull this kinds of EV tricks on their own budgets, I keep what I said; what about you?
The only thing I find embarrassing here is someone who passes themselves off a an engineer while blabbing nonsense. Not one of the current numbers for ANY electric vehicle work. FACT.
Performance and usability both are far below ICE levels. To date, even with massive subsidies, these CARS cost far more and perform far worse than their ICE versions. We are in fact years away from a practical battery powered car, much less a truck....at least one that's used to do work.
What's worse is that they (electric cars), are actually worse polluters due to the combined excessive carbon footprint they make. Between the labor and materials used to both build and buy the car, and the electric power produced to operate it they produce nearly double the effective pollution. And we haven't even talked yet about the disposal of used batteries!
Don't pass yourself off as an engineer until you know the basic truths about the real world physics! I could throw mounds of math at you, but based on your biased emotionally based posts....I seriously doubt that you would comprehend it!
I did not think that flaming was allowed on these discussion boards, and it certainly is not worthy of engineering professionals. If one believes another to be wrong, even totally screaming wrong and clearly biased wrong, the best response is a rebuttal with facts rather than a flaming criticism, if valid or not. Likewise, pointing out errors in an assertion is valid, while calling names is a poor choice.
IN OTHER WORDS, IF YOU MUST FIGHT, DO IT IN A MUCH MORE INTELLECTUAL MANNER, OK???
@rdelaplaza I am certain from your uninformed and pedantic soliloquy that you are a tower dwelling, metrosexual, wussie. Who has never done a minutes worth of real work in your life!
US rednecks actually USE our trucks every day for REAL work. We make sure your ignorant vegan backside gets supplied with all the kale, carrots, and cabbage you consume. We also provide the beef and pork and chicken you eat, when you think no one else will ever know.
Battery powered cars are still a losing, non-starter, and will be for years to come. Useable, working trucks.....may NEVER be viable!
Trucks are too heavy and have been for 30 years or more. It takes 300 HP just to go up a mountain pass when they are empty and they still lose speed. With all the weight they need 400 HP to be used as a towing vehicle. A smaller/lighter truck with 300 HP makes sense to me, but then a standard makes sense to me. Has anyone tried to pickup an automatic from any of the top selling trucks? Just another one of the overweight problems.
With a better understanding of materials’ response to load and temperature, researchers could potentially use the knowledge to improve design. The research could even help geologists studying plate tectonics.
