I though the $200 US coupon for the Mobile Connector was only for Tesla customers who ordered a new Tesla vehicle prior to a specific cutoff date in 2021.Nah, they’re just cheap and the coupon is damage control.

These efficiency numbers are for the car only. Wiring to the car resistance is additional loss.To be fair though, the efficiency depends on the resistance of the wiring used as well as its length. My WC is connected to the panel with about 25-30' of 4 gauge NM-B. If they used 100' of 6 gauge THWN in their test setup, they're going to see much higher resistive losses.
That was my understanding as well, hence the damage control comment.I though the $200 US coupon for the Mobile Connector was only for Tesla customers who ordered a new Tesla vehicle prior to a specific cutoff date in 2021.

Yeah... people maybe don't care, but car companies should care. This is not an easy equation how was with gas-powered trucks: just add few more cylinders, bigger tank - truck is ready. GM decided to do the same way... "hey we just install 220kWh battery, all done". But that truck became super heavy and even with this giant battery, struggling to make 350 miles or range. Because it's very heavy and and inefficient. And keep increasing the battery size will not solve the problem.People buying giant trucks don't really care about efficiency any more than people buying pickups care about gas mileage. It might be considered but it's not the first priority or you wouldn't be buying a giant truck in the first place. The market for trucks is different than the market for sedans.
Increasing the size of the battery is really the only solution to the problem. You're discussing the energy density of the battery itself and this is why there's so much research going into making batteries that can store more energy in less mass.Yeah... people maybe don't care, but car companies should care.

The latter isn't going to happen because you can't fight physics. Pushing through the atmosphere requires a certain amount of energy, even if the truck and batteries themselves were somehow magically made massless. Drag force=0.5*(density of fluid)*(velocity of object through fluid)^2*(drag coefficient)*(cross sectional area). Best drag coefficients are in the range of about 0.2-0.25 and even if you could somehow make a truck with a drag coefficient this low (you really can't but let's ignore this for now), the cross sectional area of a useful truck is still high and that contributes to the drag force. (Work required to move an object)=Force*displacement.So what customer going to care about is this: Cybertruck which can be charged from the electrical dryer outlet or RV outlet overnight and have almost full battery which will be enough for day of driving, or GM EV which can be charged only to 50% overnight and it will be enough only for 100 miles of range. Which vehicle customer going to choose? Super heavy truck with a big battery or super efficient truck that serves needs?
Increasing the battery size is a stupid way to try to increase range.Increasing the size of the battery is really the only solution to the problem.

... or you can just charge the battery more often.you're going to need 200-300+ kWh worth of energy in that battery.
But this very thing is the awful, annoying, inconvenient, infuriating factor that makes people detest electric pickup trucks and find them to be unusable. Having to find a place to drop and unhook your trailer and then charge the vehicle and then go back and re hook up your trailer every pathetic 100 miles is going to incredibly hinder the uptake of electric pickup trucks.... or you can just charge the battery more often.
Tesla clearly making a bet on efficiency and charging infrastructure. If you have a megacharger, to charge battery in 10-15 min, every 100 miles of range, then you can tow the trailer without a need of carrying heavy battery with 200-300kWh.
Yeah but the Model Y isn't a workhorse truck, it's a crossover and passenger vehicle. It's not suited for hauling heavy items from one farm/warehouse to another or for towing a trailer. Sure, it can tow, but it can only tow small objects (it only has a class 2 tow hitch). Try redesigning it with a class 4 or class 5 tow hitch like you'd find on a Ford F-350 and towing an object, like a large RV, that is only suitable for those classes (12,000 to 20,000 pounds) and I think you'll find the range extremely lacking without a bigger battery.Increasing the battery size is a stupid way to try to increase range.
The Tesla Model Y has a much smaller battery than the Ford Mustang EV but has a much greater range.
Tesla has done a much better job of engineering the efficiency of its cars so they can go the distance on a smaller battery.
Legacy auto is 10 years behind Tesla in engineering EVs.
Not practical or desirable on a long road trip.... or you can just charge the battery more often.
The only things I've ever seen people tow with Teslas are small trailers, not the really large stuff (due to limitations of the class 2 tow hitches). Something like this will bring you WAY below 100 miles of range: 6.7 MPG while Towing - Ford Truck Enthusiasts Forums It saps the range of ICE vehicles too, which is why extended range fuel tanks on large trucks are a thing, and there's a reason why people buy them. People have pickups that can take more than 50 gallons of fuel so they don't have to stop every 100 miles and fill up.Tesla clearly making a bet on efficiency and charging infrastructure.

Cmon! How do you roadtripping now on your Tesla? Or you don't?Not practical or desirable on a long road trip.

I have done many multi-thousand mile road trips over the past 8+ years in my Teslas.Cmon! How do you roadtripping now on your Tesla? Or you don't?
I stop for supercharging every 120-150 miles, and don't see anything wrong with it ))
I do too! Over 50 Tesla Superchargers along I 95 between NJ and West Palm Beach Florida.Cmon! How do you roadtripping now on your Tesla? Or you don't?

I charge to 100% so I roll out of my garage with the maximum range, and I drive it until I either run out of juice or want to stop for a meal.Cmon! How do you roadtripping now on your Tesla? Or you don't?
In the San Joaquin Valley on I-5 (speeds of 85-95 mph), 120-150 miles is only about 75-90 minutes. Last road trip I did well southbound because I stopped for a meal at Kettleman City and charged to 100% in 45 minutes while I was eating (and this is where I would have stopped anyway in an ICE car) and went all the way to my destination from there without stopping. But northbound things didn't work out so well. The meal was much earlier in the trip so I had to stop at Kettleman City to use the restroom but gained only about 15-20% SoC there, and had to stop again near Firebaugh because the computer said I had insufficient charge to make it to Casa de Fruta/Hollister and this was despite rolling out of the hotel with near 100% SoC. So yeah, bigger battery would be super helpful.I stop for supercharging every 120-150 miles, and don't see anything wrong with it ))
