    CyberLandr Camper / Overlander Concept for Cybertruck

    No one would overland in this thing. It is a weekend camper at best. R value of 2? This thing will have tons of gaps and allow bugs in. Where do all the mechanicals go? What about the water tanks? Plumbing? I see no practically, reliability, or effectiveness in this design.

    Independent Cybertruck Drag Coefficient Analysis Yields 0.34 Cd

    Not on pavement. Any reduction of rolling friction would be countered by more aerodynamic drag from the lift. If you were on gravel or dirt, I suspect you would see a significant benefit.

    Elon Reconfirms Production Cybertruck Will be Around 3% Smaller. Factory Delivery / Pick Up Will Be Available!

    Maybe the majority of forest service trucks in Santa Cruz are 2 wheel drive, but I have never seen a 2 wheel drive forest service truck in the mountains of Colorado.

    Elon Reconfirms Production Cybertruck Will be Around 3% Smaller. Factory Delivery / Pick Up Will Be Available!

    Maybe in Santa Cruz, but in places with snow, the majority of fleet trucks are 4x4.

    Engineering Explained: If Gas cars are banned, Can The Grid Handle Electric Cars?

    The US currently has the capability to produce 1.2 terawatts of power. If all of that was running, we could produce 10.5 petawatt/hours of energy per year. That is more than 2.5 times our current consumption. Power generation isn't the issue, it is delivery. And that isn't an issue if home...

    In weight, not rolling resistance.

    Tesla Cybertruck is Really Efficient! [Nxt Garage Analysis]

    You are assuming that a heavier tire is stiffer than a lighter tire, and that isn't the case. They claim kevlar tires are tougher, so they may actually be stiffer. Yes reducing unsprung weight will reduce rolling resistance, but again, it is going to be relatively insignificant.

    Tesla Cybertruck is Really Efficient! [Nxt Garage Analysis]

    We aren't talking about race cars where you don't care about tread life and you will sacrifice it for grip. We are talking pickup trucks in which you can swap tires out with different brands of the same size and the pressure required doesn't change. Truck manufacturers recommend a tire pressure...

    Tesla Cybertruck is Really Efficient! [Nxt Garage Analysis]

    Here is some advice. Don't reference marketing materials as your evidence. A 20% weight reduction in tires will mean a total of 40 pounds in at least a 5,000 pounds vehicle. That is 0.8% difference. That will not impact rolling resistance in any significant way. Tire pressure has zero to do...

    Tesla Cybertruck is Really Efficient! [Nxt Garage Analysis]

    Sure, maybe the smallest battery backCT will weigh the same as an F150. I based my numbers off a tri-motor. Kevlar doesn't change the rolling resistance. Tire pressure is based on the tire size and load the tire is carrying. Having a higher pressure in the same size wire will reduce the rolling...

    Tesla Cybertruck is Really Efficient! [Nxt Garage Analysis]

    7,000 pounds is a more realistic weight knowing what we know on the weight of other Teslas. A CoD closer to 0.4 is more realistic based on the evaluations that some other have already made. A CRR of 1.5 is more realistic for an off road tire. I think we are closer to 500W/mi than 400W/mi.

    Tesla WON | CAN’T be copied or caught, and are speeding up !!!! GAME OVER

    If it isn't a moneyless, classless, and stateless society, it isn't communism. Just because a party with the name communist is in power doesn't make a state communist. It is like saying that the US is a democracy when the democrats are in power and a republic when the republicans are in power...

    Tesla WON | CAN’T be copied or caught, and are speeding up !!!! GAME OVER

    Communism is a stateless, moneyless, and classless society. Neither USSR, nor China are communist. They are state capitalist.

    The US is not a democracy and you are subjugated by a controlling authority. Also, Joe Biden is extreme right, not the radical left.

    I am done arguing with you. You can educate yourself if you want, or you can just keep playing the fanboi. You can't change physics with wishful thinking.

    SPECIAL EDITION QUAD-MOTOR Cybertruck rumor

    You can be at 5,000 feet and still be pretty flat. But there are ALWAYS changes in grade. They may be imperceivable at times, but they are there. You can drive from Chicago to Denver and gain over 4,500 feet, and it is flat as hell. You single data points don't provide any such information...

    SPECIAL EDITION QUAD-MOTOR Cybertruck rumor

    Physics and the stock market are not comparable. One is quantifiable, the other is speculative. The parameters that are contained in the spreadsheet give a baseline, nothing more, nothing less.
