What kind of drive train can take that? Things going to need huge ( heavy) gears,oil coolers and pumps to pump the oil to the coolers. I wonder how heavy the truck will be.With several times the torque of a diesel - it can maintain speed going up the steepest mountain grades, and when coming back down, recharge the battery.
^This. Subtract the weight of the Diesel engine, transmission, fuel weight, etc then add the required components for EV operation , batteries, motors, etc and it’s more than likely a wash as far as an 80,000 lb legal gross weight is concerned.I wonder how heavy the truck will be.
The SEMI is expected to be less than 1 ton heavier than a similar deisel truck. If it were substantially heavier than a diesel, it would further cut into the payload capacity.What kind of drive train can take that?

It could be really light.What kind of drive train can take that? Things going to need huge ( heavy) gears,oil coolers and pumps to pump the oil to the coolers. I wonder how heavy the truck will be.
We're talking about an absolutely massive amount of power needed to charge 20+ trucks parked overnight.The range is more than a driver can legally drive in a day, so overnight charging is efficient - no wasted time charging during the driving day.
I believe the SEMI will use the Model 3 motors.It could be really light.
4 individual direct drive motors on the rear axles, for example.
No gears. No pumps. No coolers. No extra weight.
Just like the Model S Plaid, which has about 1,000 lbft of torque in a car.
Upsize the motors a bit, put in four, and yeah, thousands of foot pounds of torque.
Definitely part of an overall solution. Companies have to get this right as truck deliveries have tight schedules.We're talking about an absolutely massive amount of power needed to charge 20+ trucks parked overnight.
What if the stop is full at the end of a shift?
let's be real, the timing of the announcement has nothing to do with the actual truck production, and everything to do w/the current status of Tesla. Not a Tesla hater here, but that's reality. Between Tesla stock prices, twitter funding and crytpo prices, Elon wants a boost. This is it.Tesla has started taking SEMI orders. Got a spare $20K?
Deliveries are believed to commence sometime in 2023, but of course that's Elon time...
The reason Tesla opened its preorders is to use the funds to start its production and begin manufacturing the vehicle for its soon owners.let's be real, the timing of the announcement has nothing to do with the actual truck production, and everything to do w/the current status of Tesla.

An acquaintance of mine has a roadster on order. He has a Model 3. I think it was a 200K deposit. He paid the deposit something like 4 or 5 years ago, and was mentioning to me that he has yet to get a single follow up email telling him the status of his massive deposit! Of course, he's not exactly hurting for cash, but still...
I think the deposit is now 50K. He put it in years ago, when they first announced it, and I think he had to actually pay the entire amount upfront. It was some 'founder's edition' thing, so he'll be among the first to get it. And obviously it goes without saying, but if you can afford to plunk down 200K or so on something that will be built "sometime in the future", then you have enough money that floating that sorta deposit is NBD.The reason Tesla opened its preorders is to use the funds to start its production and begin manufacturing the vehicle for its soon owners.
Of course, we are all free to speculate on why Tesla or any company makes announcements.
The Roadster deposit is $50K; the price is $200K. You use a credit card on line for $5K and have 10 days to pony up $45K more.
Your friend is getting an incredible car. It will be built in the Fremont plant, right up the road. Tesla has learned al lot through experience; the Roadster is supposed to be the culmination of their learned experience. I can't wait to see one! But I am not holding my breath.
Tesla is not in kickstarter mode! If they're relying on these deposits to start production, then they have some serious structural issues....The reason Tesla opened its preorders is to use the funds to start its production and begin manufacturing the vehicle for its soon owners.

The Founders Edition Roadster is a limited run of 1,000 cars; they are sold out. The differences between the $200K (estimated) Roadster and $250K Founders Edition have not been stated. This sell out alone indicates $250 million in revenue for the company.I think the deposit is now 50K.

I'm looking forward to checking it out when he gets it.
The semi is obviously a very different beast though. The Roadster is a toy for rich guys and rich enthusiasts, the semi is something people are using to make money. So I have to think the tolerance for delays will be a lot different.
Ahh. I didn't realize that they would do it that way. I assumed the motor would drive a regular set of axles.It could be really light.
4 individual direct drive motors on the rear axles, for example.
No gears. No pumps. No coolers. No extra weight.

I believe that is correct. The 4680 really is not significantly different than 18650's or 2170's with regard to WH/Kg. It's advantage is lower internal resistance, which allows faster power drain and charge. Along with a well engineered thermal path to manage temperatures.The truck needed the 4680's to hit its range under load target.
Is it able to go at least 700 miles without inducing range anxiety?The range is more than a driver can legally drive in a day
Agreed, Tesla is no longer in start up mode, they are in rapid growth mode. The deposits are for materials and, more importantly, to secure the order. The deposits are probably not returnable, not sure. The SEMI is build to order vs build to stock.Tesla is not in kickstarter mode! If they're relying on these deposits to start production, then they have some serious structural issues....
Of course no on "knows" except upper management at Tesla, but I would find it hard (read: impossible) to believe that they're dependent upon deposits to start production, or that it's even much of a factor in the decision.
