This is impressive. It's interesting to see how different trucks are used - some of the eCascadia's with their small day cabs put in fewer miles but make many more stops (I saw one made 26 deliveries in a day). Range aside, the Tesla with its larger cab seems more suitable for OTR use.

As an interesting aside, WattEV has at least one Nikola truck. I didn't know those actually made it to production!

These stats are meaningless without load data.

Yes, from what I read load data will be released at the end of the event, eg:

https://www.nextbigfuture.com/2023/09/tesla-semi-shows-real-...

"The daily online results are not showing the total payload weights. The final reports will include data on the payloads."

For Tesla semi they are to be long range trips with heavy load, but we'll see in a few days.

From the charts:

constant/max speed 60 mp/h 96 km/h

charging from soC 14.12% at 11h07m10s to 77.76% at 11h56m10s so +63.64% in 49mn

Is anyone working on a system where the battery is stored on the trailer? You could have chargers at the loading bays, and the drivers would just swap trailers for the return trip. I could see it being a great option for warehouse to warehouse runs like Costco, FedEx, and the like.

Note the tweet is from the 11th and the graph on TFA is from yesterday and today.

How big is the battery? To do this by pulling it has to be hundreds of kilowatt hours.

Estimates range between 800 kWh to 1 MWh of battery.

From tesla web site: "With less than 2 kWh per mile of energy consumption, Semi can travel up to 500 miles on a single charge"

The title is misleading. It's 822 miles spread across 3 vehicles.

Edit: I see where I went wrong. Apologies.

That's not what I'm seeing here. I see the truck recharging and making 3 deliveries.

Manipulating the controls on the page, it looks like on Day 9 that Truck 1 did 0 miles, Truck 2 did 583 miles, and Truck 3 did 822 miles.

I do think that plotting "distance by speed" (rather than "time by speed") seems slightly suspect to me in terms of information content value, but the HN title seems correct.

There is separate data for each semi which can be changed via dropdown. Telsa 1 did 0 miles, Telsa 2 did 583mi, and Telsa 3 did the advertised 822mi.

There are also different teams, should you be interested in seeing how the competition performed.
