The Tesla Semi will shake the trucking industry to its roots
Elon Musk’s new Master Plan calls for an expansion of its vehicles into other categories, including buses and heavy duty trucks, both of which will unveiled in about a year. Undoubtedly, carbon emissions worldwide would fall precipitously if the general automobile consumer transitioned to a tailpipe-free electric Tesla, but that’s not what Elon Musk is after. His goal is a full frontal assault on carbon emissions of all kinds including a Tesla Semi. His objective is for nothing less than a world that no longer uses fossil fuels to power its transportation system, even on a commercial scale.
Looking back at the Volkswagen diesel scandal and why it was significant, beyond morality, diesel engines especially heavy-duty diesel trucks spew emissions on another level. To make the problem worse, passenger cars normally have a useful life of around 200,000 miles. Diesel powered tractors can be on the road for a decade or more, spewing out toxins for millions of miles before they are replaced. The pollution control systems on older trucks are rudimentary at best.
In Southern California, the pollution from drayage trucks that haul shipping containers from ports to inland distribution centers is so bad, it has sparked a number of plans to replace them with electric versions. One solution proposed by Siemens calls for equipping trucks with pantographs so they can draw electricity from overhead wires along their routes.
Former Tesla executive Ian Wright sold his stock in Tesla Motors when Elon Musk came on board. Wright wanted to attack the challenges of truck pollution rather than build some silly sports car. He has since created his own company called Wrightspeed that focuses on cleaning up the emissions from heavy duty garbage trucks. He has invented a new form of hybrid powertrain that uses a small gas turbine to recharge the batteries. The turbine is so clean, it doesn’t even need a catalytic converter to meet California’s stringent emissions rules.
The problem with electric trucks today is that the batteries need to be so large and heavy they would take up much of the space available for hauling freight. Not only that, they would be prohibitively expensive. The Wrightspeed system is a compromise that attempts to strike a balance between cost and range. It has attracted international attention and the company has recently signed a contract to re-power a fleet of diesel buses in New Zealand.
The allure of electric trucks has created an opportunity for hucksters and charlatans. Earlier this year, a Florida company calling itself Oakridge Global Energy Solutions said it had developed a battery for Freedom Trucking of Minneapolis that would haul an 80,000 lb. load 400 miles. That claim turned out to be vaporware.
Another entrant into the heavy truck sweepstakes is a company calling itself Nikola Motors — a rather obvious attempt to somehow conflate what it is doing with the work of Tesla Motors. It says its Nikola One tractor will have 2,000 horsepower. 3,700 lb-ft of torque, a 325 kWh battery, 6 wheel drive with torque vectoring and 1,200 miles of range. It relies on an onboard natural gas turbine to keep the battery charged while driving.

The design concept for the Nikola One is visually appealing and the company says it has 7,000 pre-orders for the truck worth a total of $2.3 billion. Of course, it currently has no factory, no battery factory, and little corporate infrastructure other than its website.
We can assume the Tesla Semi will not have a range extender engine of any type. How Tesla will make an electric tractor that can haul heavy loads long distances that is cost competitive remains unclear. But if Elon says that’s what Tesla will do, we can be pretty sure it will — eventually.
JB Straubel says he and Elon talked about electric airplanes long before they decided to build automobiles. And ocean going cargo vessels are some of the worst polluters on the face of the planet. Musk probably has a plan for them, too. Look for those ideas to be part of Master Plan Numero Tres.
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.
