Tesla Semi rival Daimler on electric trucks: ‘The best battery solution is going to win’
Amidst the emergence of all-electric long-haulers like the Tesla Semi, an established brand is adopting an optimistic stance about the trucking industry’s upcoming electrification. During a recent media roundtable at the American Trucking Associations’ annual Management Conference & Exhibition, CEO of Daimler Trucks North America Roger Nielsen stated that the industry’s transition towards electrification is happening at a “greater speed than expected.”
Daimler is no stranger to the idea of using electric trucks as a viable alternative to diesel-powered vehicles. Last June, Daimler took the wraps off the all-electric Freightliner eCascadia heavy-duty, which has a range of 250 miles per charge and the capability to be charged to 80% in 90 minutes. The company also unveiled the mid-duty Freightliner eM2, which offers a 230-mile range and the ability to recharge 80% of its battery in 60 minutes.
Tesla has not released the actual specs of its battery for the Semi, though Elon Musk noted that the company would be launching two versions of the vehicle — a 500-mile long range variant and a 300-mile short range version. Musk’s later statements teased improvements to the Semi’s range as well, with the CEO stating that the vehicle would likely have closer to 600 miles of range per charge. When asked by reporters about his stance on the Tesla Semi, Nielsen noted that battery quality and energy consumption would be the determining factor in the emerging electric truck market.
“The best battery solution is going to win. It’s all about energy consumption,” he said, according to Fleet Owner.
That said, the Daimler executive remains optimistic about the German legacy carmaker’s chances in the electric truck industry. Nielsen, for one, noted that he believes Daimler would have the highest number of electric trucks in the commercial trucking segment by 2020. Apart from this, Nielsen also stated that Daimler’s offerings could have an edge against the Tesla Semi, since customers would likely opt for electric vehicles that are similar to trucks they are already familiar with. With this in mind, Nielsen believes that the Freightliner eCascadia and the eM2 would probably perform very well.
“That helps create a smooth transition from a diesel-powered truck to an electric-powered truck,” Nielsen said.
While the Tesla Semi is yet to enter production, the all-electric long-hauler has the potential to be a serious disruptor in the trucking industry. The vehicle’s range and performance, coupled with the support of the upcoming Megacharger Network, would allow the vehicle to be competitive even against diesel-powered semi-trailers. Tesla is also in the process of improving the Semi, as noted by the company’s President of Automotive Jerome Guillen during the second quarter earnings call.
“Obviously, it’s going to be better than what we showed last year. There is a lot of improvements,” he said.

Tesla has so far been tight-lipped about the Semi’s improvements since its launch last year, though recently published patents have teased a number of compelling features that might make it to the vehicle. Last month, for example, a patent for an automatic tire inflation system for the Semi was published. While the ATIS would likely be used initially for the Semi, the feature could pave the way for the off-road capabilities of Tesla’s other vehicles, such as the Tesla pickup truck, the Model Y, and the Model X.
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.
