Tesla says that deliveries of its all-electric Semi will begin this year. The news that Tesla delivered in its Q1 2021 Update Letter seems to hint that the battery constraint issues that put the Semi’s initial delivery dates into question could be coming to an end once-and-for-all.
Earlier today, Tesla released its Q1 2021 Shareholder Deck, an Update Letter that brings shareholders and enthusiasts up to date on some of the lesser-known details surrounding the world’s most-discussed car company. In its Product Outlook section, the automaker revealed that the Tesla Semi is now set to begin deliveries later this year, positive news for the many pre-orderers of the all-electric commercial truck.
The news effectively can put an end to talks of battery constraints, an issue that has plagued automakers who manufacture electric vehicles for years. Tesla CEO Elon Musk has said in the past that battery constraints have been the main bottleneck affecting Semi production. As recently as March 2021, Musk said, “Demand is no problem, but near-term cell supply makes it hard to scale Semi. This limitation will be less onerous next year.” Still, it is not a new issue. During the Q3 Earnings Call in 2020, Musk said, “We need to solve the cell constraint before ramping Semi to significant volume. That’s the only real constraint on Semi’s progress.”
The Semi, due to its large size, increased range, and need for excessive power output requires a significant number of battery cells. The Semi could have been produced earlier, but it could have affected the production processes of Tesla’s mass-market vehicles, like the Model 3 and Model Y. Ultimately, the widespread consumer vehicles take priority, and the Semi project simply had to wait.
Tesla is not dealing with any issues in terms of Semi demand, however. Earlier this year, it was announced that PepsiCo. would be receiving 15 Semis from Tesla, making it one of the first companies to accept delivery of the all-electric 18-wheeler. PepsiCo. said that it expected to take delivery by the end of 2021, and Tesla’s new estimates align with these predictions.
The hype surrounding the Semi has been especially loud this year. Tesla has been building out a Semi technician team in multiple locations. The vehicle was also spotted on the Fremont Test Track earlier this year in a video released by Tesla on Twitter.

Along with the Semi, Tesla plans to continue building out Model Y capacity at both Giga Berlin and Giga Texas, both remaining on schedule with production and deliveries set to begin “in each location in 2021.” Additionally, the automaker said that Tesla’s China-located production plant in Shanghai is also set to continue expanding.
Tesla reported its seventh-straight quarter of profitability along with a revenue of $10.389 billion for the first quarter, non-GAAP earnings per share of $0.93, and non-GAAP net income surpassed $1B for the first time in the company’s history.
Tesla has started to deploy the 2026 Summer Update to owners across its fleet, and among the biggest changes are improvements to Navigation, a new startup animation for the Model 3 and Model Y, Caraoke scoring, and new capabilities for Grok.
As the update has started making its way to some cars, we can now see a few of the features operating in real-time. We will show you what some of the new features look like in this article, along with some additional details on what changed.
Not all of the new features in the 2026 Summer Update have quite made an appearance, but some of them have, so we’ll show those here:
New Animation Screen for 3/Y
Tesla is rolling out a new startup animation for Tesla Model 3 and Model Y owners. This is present in Launch Edition and Performance Model 3 and Model Y, but other trim levels do not have anything like this.

Owners can adjust the color associated with the startup animation to suit their preferences. It is a surprise that more automakers do not focus on this animation for their vehicles; it can be a great first impression piece and make the car immediately feel more luxurious.
Tesla has included this on more premium trims, but it is nice to see it on the Model 3 and Model Y.
Grok Improvements
Grok can now adjust more things in the car outside of the Navigation system. Now, drivers can adjust anything from climate to driving settings by simply speaking to the AI assistant in the car:

You don’t even have to push a button, either. Instead, you can just say “Hey, Grok,” if you have it enabled. That feature rolled out with the 2026 Spring Update just a few months back.
-
This is a great feature, especially pertinent for the Robotaxi platform, as there will be no buttons inside the Cybercab when it eventually starts giving rides to the public. It also broadens Grok’s capabilities, which were relatively limited in terms of vehicle setting adjustments beforehand.
Tesla briefly offered one Robotaxi part in its Parts Catalog for your personal car, only to remove it just a short time after it was first noticed.
Tesla’s Robotaxi camera washer apparatus was briefly available for purchase on the company’s Online Parts Catalog. The camera washer was first noticed on Model Y Robotaxi vehicles about six months ago in Austin.

First noticed by Not a Tesla App, the Camera Washer entries appeared for the new “Juniper” Model Y under a category called “Halo,” which has also now disappeared. Interestingly, Halo probably is related to Tesla’s internal “Project Halo,” which was a project that aimed to retrofit customer-owned Model Ys into functional Robotaxis.
This hardware addition would likely be required for the vehicle to operate as a Robotaxi, as the Camera Washer seems to be a non-negotiable part of the vision-based system Tesla utilizes for self-driving efforts.
However, this part has since been removed and is no longer visible on the EPC.
-
Now the true question lingers: Why would Tesla add this Camera Washer to the Model Y parts catalog? Is it planning to make it available for owners to utilize on their own cars for personal use, or will it become a prerequisite for Robotaxi operation in customer-owned cars?
While discussing the upgrade options for Hardware 3 vehicles during the Q1 Earnings Call, Tesla CEO Elon Musk had said that the company could establish small, satellite shops that would upgrade cameras and self-driving computers. Perhaps this same strategy could be utilized for vehicles that want to be included in Robotaxi but do not have the correct hardware.
AI4 is currently represented as capable of unsupervised self-driving, and the same was said about HW3 at one point, only for Tesla to admit last quarter that it would, unfortunately, not be possible. Perhaps AI4 vehicles might need this camera washer as a prerequisite, just as HW3 cars will need that camera and computer upgrade.
This could be the first hint of that’s where we are headed.
Tesla has started rolling out a broader change to the ride experience for its Robotaxi fleet by silencing turn signals, but the change is certainly polarizing.
Tesla has generally made it clear that its purpose-built ride-hailing platform, Robotaxi, will cater to the rider in nearly every way possible. This includes having climate preferences, music, and other personal settings loaded up in the car as the rider enters.
But Tesla is taking it a step further by muting turn signal chimes altogether, a change that appears to be a way to make the ride more peaceful:
Tesla has finally turned off the blinker/turn signal noises in their Model Y Robotaxis.
This is a small update, but will definitely be noticeable for riders. It didn’t really make much sense to leave the turn signal sound on when it’s Unsupervised. pic.twitter.com/ITwx60PAMO

However, there are a handful of people who are not thrilled about this change. Turn signals are a conditioned part of the human mind for those who ride in a car regularly.
-
Taking a turn without one feels strange and odd, and not hearing it click while activated could set off some alarms for riders, who might use the noise as confirmation that other drivers know of their intention to turn.
I kind of like it being on, threw me off when riding with Zoox who has had it disabled

Turn signal noises are still audible in customer cars, so if you use FSD in your personal vehicle, you will still hear the turn signal.
The move is certainly one that is unique, but not one that separates it from other ride-sharing services. In a normal car, the clicking sound confirms to the driver that the blinker is active. In a fully driverless Robotaxi, that feedback serves no purpose for passengers, other than peace of mind.
