Until you know what the weight is that they are hauling, your you dont have a clue. Your missing the most important data!!

Interesting data. It's too bad that the companies are not giving real world data. I am retired but worked for Pepsi (Tulsa) Several trucks (OTR) did daily runs to the Dallas warehouse (250 miles). Their return trip were never empty. Deadheading is loss of revenue. Anyway, good reporting. Cost analysis would be nice info too. EV cost per mile vs ICE.

Being "maxed out" at 82K lbs still doesn't tell us how heavy the payload is. Without this, we're not learning anything. And a company that wont provide this most important of information in specking out a truck, they're hiding vital information. Go spec a transport truck. I don't think you're going to find a transport company that will purchase a truck that doesn't provide all the specs. No jumping to conclusions necessary if they aren't giving you all the specs. They're hiding something vital.

The charging limits have nuances. It's not charging above 80% and depleting below 20% that is the problem. It's leaving the battery outside of that over time. So for regular driving you can use the whole range, just charge all the way and go and then charge above 20 when finished.
-
Having half the battery capacity of the Tesla means that the Freightliner and Volvo can take higher payload since the battery is lighter. So they are moving more freight using the same amount of energy.
-
Charging to 100% is not that big a deal provided you don't leave them at 100% - I'd say they've sorted out their charging so it finishes charging just before it begins the next route.
-
Seems like they are better than I thought they would be. I thought they would be fine especially for local deliveries. Once they get the megachargers in place it will be easy for them to go across the country. Not sure what the charge times are.

In the mean time, Deisel trucks can travel up to 4 times the distance before needing to refuel. On average of 1500 to 2000 miles of range.
-
Not really a fan of the fact that one Tesla Semi requires 16 or 17 car EVs worth of batteries. It's really just a tech demo.

The Internet says a trucker can average 605-650 miles a day over 11 hours. Throw in a team of drivers and it's limited to the range of the truck, maybe 1200 miles+ with the right setup. Granted this isn't what a beer or soda guy would do. The Tesla semi weighs, 20-27k pounds while a common Kenworth t680 weighs 14,2000. That's a lot of lost freight and miles. Marketing stunt it would seem.

Will be interesting to see how Tesla adapt to different markets. In some EU markets like Finland and Sweden some highways allows 34.5 m and 74 metric tons. While other use and in many cities, they have to be able to drive in narrow streets. Also, there are regulations how long a driver is allowed to drive, and charging can be done during resting period.

I only see a brief moment of regen braking, right after summiting Donner Pass on the way up Actually, there's more on the way back. There's some significant regen braking just after topping Donner Summit on the return leg, including picking up almost 2% SOC starting at 9:55.

Great information 😊
-
Lithium ION batteries are limited to 80% as Lithium metal precipitates on the electrodes at high charge levels. Lithium Iron Phosphate batteries are recommended to be charged to 100% at least weekly on the other hand. (Tesla manual data).
-
This does not seem to be a fair comparison. Tesla Semi is obviously using 2 drivers per day and charging 3 times per day. With 1 driver and charging twice, a realistic range could be 500 to 600 miles in fast traffic.
-
Awesome 😎
-
Can we have comparison at diesel truck to same route?
-
Does anyone know how much it costs to replace the battery on these trucks? Also, how long will these trucks last? Thanks

Toronto to Montreal , Canada is about 500 miles, and the speed limit on the 401 highway is 100kph(62mph)Walmart and Loblaws and Pride group logistics have ordered the Tesla Semi.

My BS meter blew the main breaker......
