I was very surprised to find out the recommended tire pressure as stated on the door sill placard was 61psi. Thanks for paying attention to the details.
The coefficient of aerodynamic drag squares @ about 55-MPH. After that threshold the drag increase is exponential. If you have a 10-mph headwind that means the CD squares @ 45-mph. If you are doing 70-mph into a 20-mph headwind you are aerodynamically doing 90-mph and sucking amps or fuel @ a prodigious rate. I would like too see range tests @ 55-mph. I bet we would find that the range of EV's would be a lot higher. A friend drives his Chevy Bolt on about 1,000 mile trips and can average nearly 5-miles per KW @ an average 55-mph.
I really don't understand why people are wanting to see tests at 55-mph. That is simply not real world. No one drives long distance at 55-mph. At least not in these un-Uninted States!
@@LarryRichelli Lol. That's called the Bolt and Leaf mentality. Thank God for Tesla who refused to settle for that. Now the race is to keep topping each other every year. The fact that large, heavy trucks now get over 300 miles so easily on a single charge doing 70mph really scares big oil and the Murdock's of the world. The diesel heads ain't happy.
That truck has Tire problems at speed - vibration out outa round tossed a wheel weight - well sinec GM is shutting down production in the USA - its will be something w a sombreros on it !!! And at 12:01 u run a stop sign ..!!!
???? GM is not shutting down production in the US. The Silverado EV production is ramping up at GM's Detroit Hamtramck facility (Factory Zero) and should be at full capacity this year. GM's second EV truck assembly line at Lake Orion is delayed to 2025.
@@ilovepinktacos because my half ton takes $200 to fill and only gives me 450 miles. And if I were to charge at home at .09/kwh it would cost me $16 for 180kw.
@@ilovepinktacos charging at home for 9 cents a KW or8f you have solar like me it’s mostly free. I travel over 45000 miles a year and I saved over $9000.00. From gas to electric. I’ve always tracked it
I’d really love an excel spreadsheet or something at the end of these range test videos that shows the average temp, range in miles, charging time, etc. like Bjorn Nyland does on all of his videos.
thats some good range for highway speeds. the model x is supposedto get 320 miles, but even in city driving it never get that high. i wonder what the real world unloaded range of the 4wt is, considering that one is estimated at 450 epa
I really dont care about a truck that even isnt available to buy to the average person...Maybe in a year?? edit* still entertaining. love the mobile charger
With such a big battery, you guys should do a hypermile test and see how much range you can get out of it. I remember when the model 3 first came out they were able to get close to 600 miles at the optimal speed of something like 25 mph. And that was with only 75kwh battery pack. It would be interesting to see if not totally relevant to anyone in the real world.
180KWh woah. my whole house only uses like 90-110 kWh per whole month. because I can run my house for 2 months if I connect this truck to my house. damn.
yea, seems low. Average American household uses 10.5k kWh per year or just under 29 kWh per day. Now, that said, the average american doesn't care much about efficiency and has some pretty old leaky stuff. If you limited your HVAC costs (space blankets and sleeping in the car...? lol) and power down major appliances for an emergency, you could probably cut that down significantly. A fridge may be 4kWh/day, but they don't have to be. The federal standards that were just enacted a few months ago dictate that a full size fridge use under 2 kWh per day. The most efficient fridges today are around 1.5 kWh/day. At that rate, you could even spare some energy to do some meal prep and cooking (with an electric range/oven) for a week or two. Store it all in the fridge you leave running. Power your phones and laptops.. Living for a couple weeks seems well within possibility. An extreme efficiency nut might even feasibly squeeze out an acceptably comfortable month out of the car.
well guys I m from Sri Lanka. so we don't need AC or heating at all. perfect tropical weather through all year. and i only 3 in my family and our fridge only takes like 125-200W i think. it s a double door fridge. freezer on top. normal cooling bottom. not a big one like US people use. we have washing machine, no dish washer. 42inch TV, house has kitchen, dinning room, living room, 2 sleeping rooms and verandah. all bulbs are LED. and it s really hot. i use an standing fan. and I run a 750W computer with 2 monitors for like 14h per day. average it will take 350W at normal working. so my electricity bill is like max $20 per month. with less than 120KWh for sure. and it s honestly too much here. gov increased the prices massively last year.
I’m curious, was this truck returned to Hertz at DIA? There was one and the same configuration there and despite my every effort, they would not rent it to me and said that there were issues with them that prevented renting to customers currently.
this is what AAA and probably other towing service company should have. it would be nice and if you have membership, you are allowed to be charge XXX miles or % for free. if not, charge for a fee.
Really think GM could have a hit on their hands..........if they can just make these bad boys in quantity enough to hit economies of scale so they don't have to charge so much.
@@danharold3087 First they didn't push production back a year. They pushed the second assembly line (at Lake Orion) back a year because they couldn't build enough modules to feed the second assembly line in 2024. The first assembly line at Factory Zero (DHAM). Will be humming at full capacity this year.
@@erikstephens34 I am happy to see GM has an advocate here. Yes GM has problems with manufacturing ultium modules. The official unveiling of the Ultium battery and platform technologies by General Motors happened during a week-long event in March 2020. Do you see a problem here. Yeah they are slow walking production because they lose money on every vehicle they sell. I hope they are using this time to design vehicles they can make and make money selling. The last thing GM should be doing is putting +220 KWh of batteries into unprofitable trucks. Better to build 3 cars with the batteries and attempt to ramp them to profitability. Cars may ramp where as the trucks are unlikely to and bleed about 3 times the money in the process.
@@danharold3087 GM 'HAD' problems with the automation company that developed the system to manufacture Ultium cells. It appears this has been recently resolved. If GM is loosing money on every EV they are making (which is false by GM's own statements) then why would they be intentionally increasing their costs by slowing production? The huge advantage of Ultium was lower costs through production scale across multiple vehicles. Yes a large 200+KWh battery pack is excessive for most people. But for some who need that capability it's a great option. But if you watched the video Kyle makes it clear why that this battery options (one of three that will be available on the Silverado EV) will likely be the least popular. The only thing GM needs to do to turn big profits on these vehicles is make more of them to amortize the overhead and capital expenditures.
Even if the wind stays steady throughout the test, a loop style route will still require more energy if there is any wind vs. no wind because aerodynamic drag increases on the square, and side winds also require more energy. Loop style pretty well negates elevation changes but not wind. I feel like this kind of gets glossed over whenever they tell us they run a loop style test. I realize there's nothing you can do about this, but acknowledge that wind always makes a difference even if you go both directions.
The coefficient of aerodynamic drag squares @ about 55-MPH. After that threshold the drag increase is exponential. If you have a 10-mph headwind that means the CD squares @ 45-mph. If you are doing 70-mph into a 20-mph headwind you are aerodynamically doing 90-mph and sucking amps or fuel @ a prodigious rate. I would like too see range tests @ 55-mph. I bet we would find that the range of EV's would be a lot higher. A friend drives his Chevy Bolt on about 1,000 mile trips and can average nearly 5-miles per KW @ an average 55-mph.
My biggest concern about calling this a loop style test is that it isn't. It's a downstream upstream test. A true loop style would be a loop giving headwind, downwind, and side wind. Changing those things would give a better overall representation for range to give an even amount of wind to every direction (as reasonably possible). You also have the issue this video really demonstrated, when you're doing a total range of 300+ miles like this you're spending 2+ hours driving in 1 direction and then 2+ hours driving back. 4 hours is a LONG time for weather to change so while you may get a bit of wind helping at one point in the test you could be getting a LOT of wind hurting you on the way back. That really throws off range in this full range test. It would be better if they had a 50-100 mile true loop to do these tests on as it would help mitigate these issues. It might make getting back to the charger every time a bit more difficult but something that could still be done with the amount of work they put into the tests.
Can we get range at different percent battery charge? 10% remaining for example. 300 miles probably. So plan for maximum range of 300 miles. Or the 4WT at 360 miles. Please don't end a video with "dangerous truck" comment. You need to stipulate what dangerous items you found. Many of us fast forward to the end.
i reckon chevy has really moved in the right direction with how they are configuring there electron powered utes . the big big big pack in a familiar chassis format should prove more realistric n useful than the other makers. the other manufacturers focusing on making n confiiguring the traybacks so they are like lifestyle vehicles either to bump profit margins or limit caniballisation of the exisiting traditioally powered options in ther fleet or miserly limiting cell size below what anyone would realistically call adequate n comnpromising genuine capability. i think when people realise the significant real advantage in work capability this vehicle has due to the power 'onboard and the ability to onbord more power efficiently is seeming a step above and aproaching comparability to a gas powered chassis. it cant be understated as to how significant the benifits of heading straigfht to the 800v backbone to the system is in leading to workable charge times. i think this platform will or should become a standout winner for the mass market , over and rather than other brands that are seeming focused on attracting and stallled at appealing to mostly tech drivers n early adopters
I bet you would have had at least 20 more miles without the winds. A headwind is not balanced by a tailwind. Drag is V^2 so say you had a 20mi/hr wind at 70mph gain would be 49% from tail wind but hit by headwind would be 65%.
That would drive up the cost. I think the silverado is 18K more. Teslas 4680 cells are also costing more to produce than originally planned, so that raises cost too. Thanks to bidenomics.
@@sprockkets 4680 cells aren't specific to tesla, they are better than using 18650 or 21700 in terms of cost, and Teslas packs are known to be some of the best packs on earth. You being so stup!d must be bidenomics fault.
So based of 1.7 mi/kwh it seems it has 193.5kWh available to use (329 miles). But I assume it is rounded. If we assume 1.75mi/kWh it is still 188. More than expected 180.
Cells are rated for discharge to 2.5v. Truck pulled it down to 2.4v. These NCMA cells can operate down to about 2.2v. Its completely fine given they're recharging it right after it dies. Same principal with SLA. Discharge it to its min, but if you recharge after you're done using it then no harm done.
Excellent stuff - a tow charge would also have been an interesting finish to the video. For your 48A L2 charger, what volts is that? Likely 208V from 3 phase industrial, but I'm curious about an episode on 277 volt charging for apartments and businesses - how many cars can take 277? It's cheaper to provide that voltage than 208 as I understand it. EV Buyers guide did an interesting dive on it in video CYiq3pen9TQ - would like to see Out of Spec's take (if you have not covered it already)
Could just use the Cybertruck as the rescue vehicle next time, right? No need for the generator! Pretty entertaining, and granted that the diesel generator provides higher rate of charge than the NEMA 14-50 240V outlet in the Cybertruck!
Cynamon roll is all you need when you screwed up. Good video, poor execution. I expect people who do this kind of tests know when to turn around and make it to the charging station.
My former long bed (larger tank) crew cab F350 diesel would get almost 700 miles range. Using expensive diesel. What is the point? Sounds impressive. Until one realizes it was just over 20mpg. Same with this Chevy. 188kw, or 225+ is the only reason for the range. However, based on cost of electrons, instead of over 100mpg-e, Chevy got less than half.
I've watched plenty of your EV content and yall have always done a phenomenal job keep it up! Super informative content as I look to purchase my first EV. One ask, I do wish the range test was more realistic with at least 75-80 mph. Most highways in Texas are at the lowest 75 and some even go to 85. 70 Mph does not provide an accurate representation for true highway driving.
Hauling that entire diesel generator trailer with the DC fast charger on it, and running it to 13% charge on the truck netted an equivalent energy of ... 2/3 a gallon of gasoline! Well done! Next time just tow-charge with the Rivian?
All this range testing is fun but I have to say that taking a road trip in my Lightning extended range is so easy, especially now with Tesla chargers that I don't even think about it. What more do I need than a Cadillac comfortable vehicle with good air condoning and good music system.
587Wh/mi for the Silverado compares to 488Wh/mi for Cybertruck. So the CT is 20% more efficient than the Silverado on the same test basis. If CT has a 180 kWh battery it would have traveled 368 miles.
@@mattc6854 look at the weight for pack level though 2,400# or more for the Silverado(220kwh version is over 2,800# per munro live so I'm est 400# less for the smaller 180kwh pack vs just 1,500# for the ct structural pack with seats&floor pan! So the ct would still be lighter. 😎
They will only sell well if GM can keep themselves out of bankruptcy or needing another government bailout. I will be really surprised if these Silverados actually come to market.
@@LarryRichelli Lots of folks said the same thing about the Cybertruck. In fact, the Silverado is on the market now. There are fleet customer trucks on the road now, and private customer orders are being accepted by dealers. What is in question is GMs commitment and ability to make them in quantity. We'll see how that goes.
The car is not actually fully dead. The battery protection system ensures there is bottom buffer and there is room for safety critical systems like the hazards.
All this running it until it dies is just perpetuating the myth of EVs dying on the side of the road. It makes no meaningful difference to arrive with 1% and extrapolate the remaining range. Still love Out of Spec! Thank you for all the hard work!
@officialyasir. I agree that a test until 1% is decent, but 2 reasons for testing until dead is to test whether a car has a buffer, and whether it gives adequate warnings and is predictable before it stops running. That's actually fairly important. Teslas are known to have a ~5-10 mile buffer below zero, but not all EVs do. In the past some EVs cut power or died ABOVE 0% SoC, which would be good to uncover.
@@KyleConner Fair enough. Can you clarify what all is getting tested by driving past 0%? It's good to know the buffer for sure but then I have also heard that the buffer is not consistent. I guess we get to see how to jump the LV battery if that ends up dying too. Let me know if I'm missing anything else. Thx!
Just show that they had to have a diesel powered generator to charge a pice of crap EV truck if you had been pulling a camper that was heavy you would have gotten about 1/3 the range
Anyone else find this absurd? Talking about tail and head winds WHILE DRIVING TRUCKS! Should put a sail on them. And an electric truck carrying a diesel generator, to be able to charge itself.
Jesus, a battery exactly 3 times the size of the one in my Model 3 standard range, and it only managed 60 more miles in the 70 mph range test. 200% more battery = 23% more range.
@@glennorcutt5835Maybe, but it doesn’t have to be this bad. The CyberTruck somehow managed 305 miles in the 70 mph range test with a MUCH smaller battery than the Silverado. Not saying I like the CyberTruck, but it’s crazy that it has a 32% smaller battery, yet only got 7% less range than the Silverado WT3. A little bit can maybe be explained by the wind, but still, the Silverado is very inefficient, even by truck standards.
