Welcome to the Tesla Space newsletter, our 115th issue.
We’ve got another great week with updates behind us.
Before we kick it off — in case you missed it, I published a deep report on Tesla vs Robotaxi Industry, part II for all our Tesla Space Insiders. We’d love to have you with us!
Here’s what’s on the Tesla Space menu today:
MACROHARD gets more real, Digital Optimus coming to cars and Superchargers
Terafab Project launches in 7 days
Roadster unveil in late April
Cybercab showcased in Austin, a few more bells and whistles, including braille buttons, ambient light, and light.up robotaxi decals.
Tesla Supercharging for Business explained;

Before we kick off, here’s our latest Tesla Space video: Elon Musk Reveals New SpaceX Starship Update!
Done? Let’s get on with the Tesla Space news this week ↓
X OF THE WEEK

There’s a lot to unpack here and to be frank, it (currently) even goes over my own head a bit.
Elon also dropped the casual follow-up: ”Oh, and it works in all AI4-equipped cars, so your car can do office work for you when not driving. We’re also deploying millions of dedicated Digital Optimus units in the field at Superchargers where we have ~7 gigawatts of available power."
Max de Zegher from Tesla Charging expanded on this plan:
"Tesla Charging teams will be helping to get Digital Optimus units energized.
Especially at long-distance Superchargers, we have large interconnections built for dependable travel on peak days, but sit mostly idle outside of holidays. We’re going to need a lot of compute and make efficient use of the grid through distributed compute."
… 7 GIGAWATTS?! Now we’ve know the build-out for the ~80k Superchargers have been large, but still, wow.
We’ve seen Elon play the compute play better than nearly all of the industry. He has talked of the cars being interference nodes before. So interesting to see Superchargers coming into play!
We’ll keep an eye on MACROHARD. And once I understand more, perhaps I’ll drop a deep dive on it if you guys want (let me know).
TESLA NEWS
Elon says:
"Terafab Project launches in 7 days"

Related, likely: Joe Tegtmeyer shows a large plot of land next to Giga Texas and writes:
"So … am I going to need to get a more powerful drone? Massive construction site prep just north of the factory off Giga Texas property and now Elon hints at the start of the Terafab project in addition to a 10M/year Optimus factory & supporting facilities?
The scale of the area under development rivals that of the original site for the main factory building … something big seems to be underway here!”
Quick takes:
Video: Elon live interview at Abundance Summit.
Tesla has sued its former supplier Matthews International in California federal court for allegedly stealing trade secrets related to Tesla's battery-manufacturing process and sharing them with its competitors. Bonne Eggleston (lead of 4680 cell program) writes a longer post starting with: "
Buyer beware: Matthews International stole Tesla's DBE technology and is now subject to an injunction and liable for damages."2026 Model Y's are getting a software update feature "Comfort Braking": "Your Tesla now provides a smoother feel as you come to a complete stop during routine braking."
Elon: “New Roadster unveil probably in late April”. Interestingly, the next earnings call will take place on April 22nd… I also saw an interesting comment from Travis Kalanick, the founder and former CEO of Uber:
“When I’ve run into people who are in the know, I inquire, they tell me nothing, but their eyebrows raise and their eyes widen in a way that can only mean something of sorcery and magic is coming…”

ROBOTAXI, FSD
Tesla Cybercab was shown in Austin for the SXSW event, along with Optimus. Tesla drove the Cybercab in (or …around?) in that glass box we've seen before, pulled by Cybertruck:

We learned a couple of new small details about the Cybecab, like Eric Earley, the lead engineer of Cybercab saying:

He also said elsewhere that "This combined with the door kinematics, a wheelchair can park parallel to the seat with plenty of room unlike traditional doors."
Cybercab will also have braille on both the interior door releases as well as the hazards button for blind/visually impaired people. The hazard button is also an emergency STOP button for the vehicle.

There were also new Robotaxi decals on the body which lit up, seen well in evening pics here:


yes, the puddle light shows the logo too
Video: Tesla Cybercab new lights were powered, you can see team open frunk & flip the switch to power off the car in this video (while hiding what's under the hood).
Oh, and there’s an ambient lighting strip also running all across under the seats:

Tesla was reportedly using a phone to control the Cybercab when it was being put into position.
Here’s how the Cybercab charge port looks like now. I would not be at all surprised if a charge port does make it to production version of Cybercabs for the time being despite Elon saying it won’t have one (due to wireless charging), even if for a backup solution.

Optimus was there too. Here is a close-up video of Optimus’ hands when handing out water. The dexterity is crazy.
Video: Just like a human would. “Full Self Driving goes around huge wrecked tour bus, FSD handled it amazing! Went around completely off the road and through super bumpy grass / dirt”
Also just in, we get a little breadcrumb on the Cybercabs we’ve seen testing on the roads:

TESLA ENERGY
Tesla has released a new blog post, a deep dive with all you need to know, really, about Supercharger for Business. Here’s my favorite bit from there, detailing exactly what the business, whether it’s a gas station, real estate owner or even another charging network (as we’ve seen) gets or needs to handle:

U.S. Government has officially announced that Tesla and LG Energy have signed an agreement to build a $4.3 billion lithium iron phosphate (LFP) prismatic battery cell factory in Lansing, Michigan, with a 2027 start of production.
Tesla Charging says: “Gigafactory New York built their last V3 Supercharger cabinet, marking the end to 15k+ V3 cabinets over 7 years. V4 cabinet line is ramping up!”

Tesla has enabled free Supercharging at these locations in the UAE, Doha and Saudi Arabia due to the ongoing conflict in the region.


Tesla Energy: Tesla can soon start supplying British homes with electricity after it was granted a licence on Thursday.
The country's energy regulator Ofgem said Tesla Energy Ventures, a unit of Tesla, had now been approved as an electricity supplier after a process which began last July.
MUSKONOMY

xAI (now part of SpaceX)
Elon says: "xAI will catch up this year and then exceed them all by such a long distance in 3 years that you will need the James Webb telescope to see who is in second place"
For anyone interested, I calculated that this means the second place to xAI will be roughly 930,000 miles (1.5 million kilometers or ~0.01 AU) away in 2029.
He seems to mean it, too:

Elon also: "xAI was not built right first time around, so is being rebuilt from the foundations up. Same thing happened with Tesla.”
“Many talented people over the past few years were declined an offer or even an interview at xAI. My apologies, @BarisAkis and I are going through the company interview history and reaching back out to promising candidates."
xAI is also clearly going back into bulding it's coding features out, which Elon has admitted they are behind on, has SpaceX/xAI has just hired Jason Ginsberg and Andrew Milich, two senior leaders from Cursor.
Elon said on future builds: “By this weekend, xAI will have three Grok Build models in training simultaneously”
Elon on the OpenAI lawsuit: “Btw, the proceeds of any legal victory in the OpenAI case will be donated to charity. I will in no way enrich myself.”
SpaceX
SpaceX has officially crossed 10,000 active Starlink satellites in orbit tonight. Over two-thirds (66%) of all satellites currently in orbit are now SpaceX satellites.
Remember how I shared that Amazon has filed a formal petition calling on the FCC to deny SpaceX’s 1 million-satellite proposal for orbiting data centers, going as far to claim the project would "take centuries to deploy”?
Well, the FCC just officially fired back at the nonsense:


COMMUNITY CORNER
We’re done for today! We strive to be the most value-packed and concise Tesla-related newsletter out there. How did we do?
FEEDBACK: What do you think of today's issue?
Great feedback last week, another 100% thumbs up. Actually, I took a look at the brief history of this poll - I’m not sure how long I’ve run this particular version, but the 97.73% thumbs up over 3,695 votes from you… humbles me. Thank you 🙏

Let’s keep going! Here are some of the comments you left me this week:
Glen said:
“Musk is my HERO--what a brain!”
— a hero to many and a nemesis to maybe even more. Can not say he hasn’t made an impact on the world either way!
E said:
“Nice job guys ”
Bill said:
“OK. Meets my needs. Maybe less semi, but that is because I am not a trucker.”
— ☑
(I think most of us are truckers here, just geeks ;))
M said:
“Love all your works - keep it coming!!!”
J said:
“More links to in-depth sources”
W is
“Lovin'it!”
K said:
“It’s nice to know how all companies are rocking it”
T said:
“Loved the piece on the Semi.....looking awesome. Maybe go into a little depth on one Tesla product in each issue”
— That’s a great idea. I’ve kept the real Tesla vs Industry deep dives mostly to the Tesla Space Insider members, but we can perhaps create some version here as well from time to time!
See you next week for more,
