Dude you just made it all come together for me and it makes sense. Elon said on Joe rogan that roadster is desert and just so happens to have a 200kwh battery. Cybertruck comes first as it will be the drive train in roadster so cybertruck will sell in mass so the investment on the plant gets returns faster than the roadster would

Excellent use of physics to estimate the Tesla Cybertruck battery sizes. That's been an ongoing mystery, but I think your figures are very reasonable and likely to bracket the range, from 86 to 200 kWh.

It would be really cool to be part of the network of Tesla's that replace Uber and Lyft! We could have a little reality show which would be a type of advertising through our channels that could inevitably lead to more people buying Tesla's!

Of course this channel will talk about Nikola Tesla, Energy generation, Health and well-being, Tesla motors, Elon Musk, SpaceX, etc. I live just outside of Toronto Canada and could really use some advice on how to get my channel off the ground. I've sent several messages to Elon Musk on Twitter but he gets so many messages in a day or mine probably get overlooked. I think I could be doing a lot more to help people get a Tesla in their driveways faster. I also believe that if you're going to have an EV you might want to have solar generation and battery storage which I also have a business plan to implement. If you like these ideas or have some of your own to offer, I would really like to know. I do appreciate all of you and your comments.

Great content, but I don't quite understand the focus on tire resistance. There is always an expected loss of efficiency with aggressive tire size/type, but the utility resulting from this is one of the many reasons the CT is so appealing. Street radials would diminish off road performance and general aesthetics. Beside the point, tires can be easily swapped if efficiency is your main concern in a utility vehicle. Just my 2 cents. Cheers.

Nah its fine, just change playback speed to suit.

Bad assumption that the Cyber Truck drivetrain will be more efficient than either the Model S or Model X. Just look at pickup trucks vs sedans and SUV and you see their mileage is far worse, even when using the same engine and transmission. Look at city/highway MPG for the F-150 5.0L (16/22) vs a Mustang (21/31) or Silverado Trail Boss (15/20) vs a Camaro SS (22/30). All of the trucks get at least 30% worse mileage due to their larger and heavier tires, greater air resistance and shorter gearing needed for towing and moving a far heavier vehicle. The bigger the tire, the more energy required to spin it at speed. You also left off side mirrors for the frontal area of the CT, which are required and must be oversized to allow for towing in trucks. The Cyber Truck will not be lighter than the Model X if it is to have any off road driving capability. The Model X has a car's suspension, that would be destroyed in no time trying to handle the punishment of off road driving. Everything underneath must be far beefier to handle the impacts expected. In addition, Elon stated a payload of 3,500 lbs, which requires a massively stronger bed than an F-150, which is rated at less than half that and its bed is made of aluminum, not stainless steel. Finally, the structural battery pack must be far stronger and heavier than those of the Model S and X since it is doing double duty. The pack must handle the massive torsional loads of the truck as it rock crawls and pounds over rough roads. It must also be resistant to puncture from rocks and debris expected to be encountered off-road. That will take a lot of steel and Kevlar. The lightest CT will outweigh the Model X. The tri-motor big battery CT will be far heavier. I understand you love Tesla, but you shouldn't let that tint your scientific judgement. The requirements for an off road truck are far different than a car or a small CUV like the Crosstrek. The CT will have a tough time beating the 87% efficiency of the model X. You should also remember every BEV has been heavier than it's equivalent ICE competition and the Cyber Truck would be quite the magic trick if it beats that trend.

I will be so impressed if the Cybertruck gets anywhere around 200 wh/mile. I average 150/180 in my model 3. That would be incredible. I’ll have to do some tests when I get my Tri motor.

That was interesting.

i dont know why people think europe only uses metric its literally entire earth except usa and not just europe. yes i am aware one or two more companies use imperial but u get the point

Cybertruck weight is going to be nearly impossible to calculate, we don't have any current vehicles with the structural battery to compare with for a scaling factor... I need to stop commenting halfway through a video. You did as good as possible i think.

One problem here is the drivetrain can be much different between a car and a truck. For instance, my truck has a conservative torque multiplier of 40, making 16000 torque which will waste energy but allow for crawling over obstacles. The cybertruck may have extra gearing for the same thing

For the battery sizing don't forget that the depth of discharge of the battery is never 100%. That is, when model S battery nameplate energy is 62 kWh, in reality you will never actually discharge this amount of energy in one cycle.

As long as the pump shuts off and the readout stops moving it shouldn’t matter if you put in 10 or 11 gallons as long as you record the readout right??

@chargeeverywhere

3 жыл бұрын

Correct. However, the mechanism that shuts the pump off is a mechanical system that is dependent on several operating pressures within the dispenser. It's my understanding (and experience) that different pumps behave differently due to either differences in construction, flow rates, etc. Sometimes when I fill up the car the gauge will not move from full for say 50 miles, while other times it begins to fall immediately. In the past when I was trying to get really accurate mileage numbers I would fill right up to the gas cap, but that isn't recommended for several reasons.

I'm a noob, but isn't the equation at 6:58 supposed to be written Crr = 0,005+1/(2,6 bar)*(0,01+9,5*10^-7*(104,6 km/hr)^2)

A very interesting analysis, but when you measure the front area of a vehicle you don't take in account the shape/aerodynamics, a car is not a flat wall pushing thru air, its designed to push the air on the side and reduce turbulence on the back giving this famous CX index. The Cybertruck with its recessing back slope has certainty a better CX than a standard pickup truck. Electricity in the US is created at 80%+ from steam turbines, powered either by natural gas, nuclear or coal, those turbines have an efficiency of about 35%, its not because those turbines are hidden miles away that it make an electric car 90% efficient, you have to take in account the thermal to electric power loss in you calculation. Otherwise it would be like saying a diesel electric locomotive is 90% efficient as the electric motors are very efficient but the diesel engine is not so much. The 3 motors 800km range truck will be at least 600kg heavier than the single motor 400km truck, requiring more batteries and will have a worst km/kw, something to consider in your chart.

I Have view this video twice and reviewed selected parts of it numerous times. I clearly see that the Subaru's work efficiency is around 23% but I cannot find a corresponding percentage number for the Cybertruck. I only see "really efficient". On the percentage scale between 0-100, I do not know where really falls. Someone, a little hep please?

Thank you very much that you used practical/useful units in your calculations and not these stupid “freedom units”. The US should switch initially to the metric it’s just a habituation and makes way more sense!

Here is the problem. Elon has said several times that cybertruck numbers are going to exceed the ones stated. He also said the new standard minimum mileage for evs is 300 miles. I can guarantee that that base model will be 300 miles minimum.

we already know that gasoline engines are max. about 1/3rd as efficient as electrical motors. There should not be huge differences in drag (because it scales so much with velocity) and because most car shapes are similar and similar in their drag coeffcient.

That was a mouthful but thanks for using the international standard of units “Metric”. I still wonder why when the Americans stuck with the British system when they got out from under their rule. I wonder why they made their gallon smaller too! So glad that over a hundred years ago they the U.S.adopted metric, even if the average person still uses imperial units, all foreign trade is done in Metric. So why not just convert to metric for everything else? Other countries have, Australia for example.

Freaking awesome. My brain hurts. That was amazing math. I’m so curious now to see how your predictions do when the CT hits Sandy Munros shop. Once again I’m in awe of the quality of your production. Epic.

Ironic that the SAE is EXACTLY 10 times harder, thats the only time SAE is an even multiple of anything...

The Cybertruck is so efficient because it just uses the electricity necessary to power the computers with which it was designed. The Cybertruck doesn’t yet exist. Talking about it’s efficiency is like talking about how great a water powered car is.

One critique I have. It seems that you compare the Tesla weight to a Subaru wagon, or there about. This might be true, but the reason a Ford F150 (or whatever) is heavy has more to do with it's hauling and towing ratings and general utility, than your car. Given that logic, the Tesla should be at least a little heavier than the F150 (unless the Tesla isn't expected to really be a truck). Generally, batteries are stiil heavier than fuel. Trucks get terrible mileage simply because they are required to have a certain level of utilitary capacity.

OMG! There is so much technology on the Cybertruck to make it efficient. No wonder Sandy Munro is crazy about it.

So efficient, it's not even here yet.
