Elon has teased the next Boring Company merch: Uranium in Uranus.

I won’t mention it here that I have three unopened bottles of Burnt Hair at home…


TESLA SEMI

Important note: the Semi Rollout Event at Tesla's new Semi factory in Sparks, Nevada is today, September 24, and Tesla is livestreaming it at 6 PM PT (9 PM ET)!

Tesla named primary truckmaker on a 2,500-truck order

ZET SCALE announcement naming Tesla as primary manufacturer for 2,500 electric Class 8 trucks

via Catalyst Mobility

A group of the world's largest shippers has made the largest electric truck order in US history, ordering 2,500 battery-electric Class 8 trucks in one go to hit the US roads. Tesla was picked as the only primary manufacturer, with Kenworth, RIDE and Volvo named as secondary OEMs that carriers can pick instead.

The order runs through ZET SCALE, a new private-sector alliance jointly operated by Catalyst Mobility (the nonprofit formerly called CALSTART) and the Smart Freight Centre. The Alliance's ambition runs to 10,000 trucks and beyond.

❝

"The Tesla Semi is designed for lower cost per mile operations than diesel. ZET SCALE's goals are exciting because they take the operational cost advantage and predictability that electricity provides and amplifies it at scale. We are proud to have been the primary selection in this RFP and look forward to giving shippers and carriers a new competitive edge."

— Dan Priestley, Director, Tesla Semi Program

No split between the four truckmakers has been published anywhere, so treat any Tesla-specific count you see as somebody's guess.

🇨🇦 Canada's first Megachargers

R.R. Plett Trucking is preparing to install Canada's first Tesla Megawatt Charging System chargers, with two 1.2-megawatt sites planned for Langley and Kamloops, British Columbia.

The company expects to receive 12 Tesla Semi trucks in June 2027 and says the new chargers will allow the trucks to move toward double-shift operations.

Grok Bot moves into the car

Grok Bot is now live in Tesla vehicles.

It sits inside the existing Grok voice interface, not as a separate app. You can check your email, manage your calendar or order something online just by talking to the car.

For now it is limited to SuperGrok Heavy subscribers, with other tiers to follow. Connectors, which link services like Gmail to Grok, are open to all users and get set up in the Grok app. I already found that Spencer was able to get his FSD to pull over through just the voice on Grok in his Tesla, through a connector he made.

That’s something I’m sure that we’ll see Tesla develop sometime soon as a native integration too.

Roadster reservations are open again

The unveil event is on October 1st

Ahead of the October 1 reveal, Tesla has reopened Roadster reservations. It takes a $5,000 card payment up front, then a $45,000 wire transfer within 10 days. Same as before. And the price is still not set:

“The estimated purchase price of the vehicle, if provided, is only an estimate. We are still working on what options, features and hardware the vehicle will have and so cannot confirm the exact price just yet."

The FAA has also placed a temporary flight restriction over SpaceX's McGregor test site near Waco from September 18 to October 2, covering a 1.5 nautical mile (2.8 km) radius from the ground up to 10,000 feet (3,048 m).

The first Cybercab with Texas-made cathode

Tesla has built its first Cybercab powered by cathode material made in-house, folding one of the most expensive and most Asia-dependent steps in battery manufacturing into the same Texas complex that builds the car.

Tesla's official Robotaxi account announced the milestone on X, crediting the car to what it called the first large-scale cathode plant in the Americas. Bonne Eggleston, Tesla's VP for its 4680 battery program, highlighted that this is just the first of many:

Quick rounds:

  • The Model 3 RWD and the Model Y L Launch Series are sold out for 2026 for new US orders, going by the delivery estimates on Tesla's order page.

  • 🇩🇰 There are now 100,000 Teslas on the road in Denmark.

  • Tesla app 4.61 adds passkey logins, and the Supercharger site maps with stall layouts and live occupancy now cover nearly every US Supercharger.


ROBOTAXI, FSD & CHIPS

First off — there’s a 1-min video from the new Cybercab’s tour from Australia that seems to show the privately owned Cybercab user interface.

🇨🇿 Czechia makes it seven in Europe!

Tesla's FSD Supervised is now cleared for Czech roads,

making Czechia the seventh European Union country to approve the advanced driver-assist system.

The approval lands about two weeks before the EU's Technical Committee on Motor Vehicles votes on bloc-wide authorization on October 6, which could open all 27 member states to FSD Supervised.

Tesla Europe confirmed the approval on X, noting that rollout to Czech customers will begin soon:

Czechia joins the Netherlands, Lithuania, Estonia, Denmark, Belgium, and Slovenia on the list of EU countries that have individually cleared FSD Supervised.

Just for the memes

The Texas DMV registry now lists 69 Cybercabs in Tesla's robotaxi fleet, up from 58 on September 19.

This is how they announced reaching 67:

Well, here’s something they didn’t announce but certainly did for the same reasons. Today, the whole Austin fleet official count from the Texas DMV is:

TESLA ENERGY

Today is the Supercharging network’s 14th birthday.

In the 14 years, it has expanded globally to ~85,000 Supercharger stalls at ~9,000 locations. 🤯

I dug up Elon’s first announcement video of the Supercharging network from 24th of September, 2012 — see it by clicking on this:

I don’t know if there was anyone who truly realized the size this thing will grow into. Oh, and the official @TeslaCharging account on X just reposted my other post linked to this:

Also, anyone remember the earliest renders from Tesla? Here’s one:

Electric Son's first Houston Supercharger for Business site (the ones where the third party buys the Superchargers to deploy on their grounds) pairs 325 kW charging with an all-electric coffee truck. The Coffee Fellows’ coffee truck will be there every weekday from 7am to 2pm!

We had some direct input from Matt Simpson, Founder of Electric Son, for this article.

A 580 MW power plant made of Powerwalls

Sunrun and Tesla sent 580 MW from home batteries to California's grid during the September 9 heat wave, over a three-hour evening window. Around 110,000 Tesla Powerwalls supplied 517 MW of it, and other batteries the remaining 63 MW.

Quick rounds:

  • Powerwall 2 owners in North America and Australia can now add a Powerwall 3 to expand their storage.

  • Cybertruck Powershare with Powerwall 3 is now in update 2026.27.10, which Tesla says extends home backup by over three days. Powerwall 2+ support comes later this year.


MUSKONOMY

SpaceX

SpaceX is now targeting as early as Monday, September 28 for Starship Flight 14, pending regulatory approval. It is meant to be the first Starship to reach orbit and the first to deploy satellites: 26 next-generation Starlink V3s.

Booster 21 and Ship 41 have both rolled out to the pad at Starbase:

NASA has also ordered three more crew flights from SpaceX for $946 million, Crew-15 to Crew-17, which takes SpaceX to 17 missions under the contract.

And United says it has flown more than 31 million passengers on Starlink-equipped aircraft across more than 464,000 flights, with NFL games now on the seatback screens.

The Boring Company — the Hyperloop is back!

As you saw in our video this week, Elon says the Boring Company is working on a precursor Hyperloop tunnel between Austin and San Antonio, at over 200 mph (320 km/h):

Earlier this month, the company also raised $3 billion at a $23 billion valuation in a round led by the UAE, and says it now plans more than 150 km (93 miles) of tunnels there, on top of the Dubai Loop.

Great read Canberra Australia"
