The Tesla Semi program is arguably one of the most intriguing within the scope of the company in recent memory. But it’s only getting started.
During the IAA Transport Show in Germany today, the Semi’s Head of Engineering, Dan Priestley, unloaded tons of new details on the vehicle, including plans to leverage several different variants of the electric truck, how its efficiency stacks up, and various Easter eggs that the company has discovered through its fleet operation thus far.

Tesla Semi Configurations
Priestly said Tesla will develop several configurations of the Semi so that they can be purchased according to the buyer’s needs.
Thanks to Tesla’s vertical integration, manufacturing will be simple.
Mass production at the new Semi factory near Giga Nevada will scale to 50,000 units annually.
Priestley said:
“We aim to be as competitive at an upfront price with diesel as possible, in order to accelerate the adoption of electric trucks as quickly as we can. Again, this is on lock for Tesla’s deep vertical integration, and we will plan to leverage this into multiple variants…We will be taking on a wide variety of applications and vehicle types.”
Tesla Semi Efficiency
Tesla, along with the companies that have been operating the vehicle in their pilot programs, have routinely flexed the efficiency of the Semi.

But Priestley said today at the conference that common industry numbers are approaching 100 kWh per 100 kilometers traveled.
The Semi has already achieved this.
It will only get better when Tesla comes back with a high-volume version of the Semi. Higher efficiency means lower battery mass and cost, meaning a less expensive product and more advantages for the customer.
Fleet Data
Despite the Tesla Semi being a vehicle that is relatively new and only has operated on a very controlled basis, only being delivered to a handful of companies.
Here are some of the stats Tesla has logged so far for the fleet:
- Over 4.65 million miles have been driven since the Tesla Semi pilot test fleet started operation
- One Tesla Semi unit has over 248,000 miles driven — it took only 18 months to get to this point
- The fleet has a 95 percent uptime — this includes scheduled and unscheduled maintenance

Elon Musk confirms Tesla FSD V14.2 will see widespread rollout
Musk shared the news in a post on social media platform X.

Elon Musk has confirmed that Tesla will be implementing a wide rollout of Full Self-Driving (FSD) V14 with the system’s V14.2 update. Musk shared the news in a post on social media platform X.
FSD V14.1.2 earns strong praise from testers
Musk’s comment came as a response to Tesla owner and longtime FSD tester AI DRIVR, who noted that it might be time to release Full Self-Driving to the fleet because V14.1.2 has already become very refined.
“95% of the indecisive lane changes and braking have been fixed in FSD 14.1.2. I haven’t touched my steering wheel in two days. I think it’s time, Tesla AI,” the longtime FSD tester wrote.
AI DRIVR’s comment received quite a bit of support from fellow Tesla drivers, some of whom noted that the improvements that were implemented in V14.1.2 are substantial. Others also agreed that it’s time for FSD to see a wide release.
In his reply to the FSD tester, CEO Elon Musk noted that FSD V14’s wide release would happen with V14.2. “14.2 for widespread use,” Musk wrote in his reply.
Mad Max mode makes headlines
One of the key features that was introduced with FSD’s current iteration is Mad Max mode, which allows for higher speeds and more frequent lane changes than the previous “Hurry” mode. Videos and social media posts from FSD testers have shown the system deftly handling complex traffic, merging seamlessly, and maintaining an assertive but safe driving behavior with Mad Max mode engaged.
Tesla AI head Ashok Elluswamy recently noted in a post on X that Mad Max mode was built to handle congested daytime traffic, making it extremely useful for drivers who tend to find themselves in heavy roads during their daily commutes. With Musk now hinting that FSD V14.2 will go on wide release, it might only be a matter of time before the larger Tesla fleet gets to experience the notable improvements of FSD’s V14 update.

Multiple Tesla Cybercab units spotted at Giga Texas crash test facility
The vehicles were covered, but one could easily recognize the Cybercab’s sleek lines and compact size.

It appears that Tesla is ramping up its activities surrounding the development and likely initial production of the Cybercab at Giga Texas. This was, at least, hinted at in a recent drone flyover of the massive electric vehicle production facility in Austin.
Cybercab sightings fuel speculations
As observed by longtime Giga Texas drone operator Joe Tegtmeyer, Tesla had several covered Cybercab units outside the facility’s crash testing facility at the time of his recent flyover. The vehicles were covered, but one could easily recognize the Cybercab’s sleek lines and compact size. Tegtmeyer also observed during his flyover that production of the Model Y Standard seems to be hitting its pace.
The drone operator noted that the seven covered Cybercabs might be older prototypes being decommissioned or new units awaiting crash tests. Either scenario points to a ramp-up in Cybercab activity at Giga Texas, however. “In either case, this is another datapoint indicating production is getting closer to happening,” Tegtmeyer wrote on X, highlighting that the autonomous two-seaters were quite exciting to see.
Cybercab production targets
This latest sighting follows reports of renewed Cybercab appearances at both the Fremont Factory and Giga Texas. A test unit was recently spotted driving on Giga Texas’ South River Road. Another Cybercab, seen at Tesla’s Fremont Factory, appeared to be manually driven, suggesting that the vehicle’s current prototypes may still be produced with temporary steering controls.
The Tesla Cybercab is designed to be the company’s highest-volume vehicle, with CEO Elon Musk estimating that the autonomous two-seater should see an annual production rate of about 2 million units per year. To accomplish this, Tesla will be building the Cybercab using its “Unboxed” process, which should help the vehicle’s production line achieve outputs that are more akin to consumer electronics production lines.

Teslas in the Boring Co. Vegas Loop are about to get a big change
Elon Musk has a big update for Teslas that operate within the Boring Company’s Vegas Loop.

Tesla vehicles operating in the Boring Company’s Vegas Loop are about to get a big change, CEO Elon Musk said.
In Las Vegas, the Boring Company operates the Vegas Loop, an underground tunnel system that uses Teslas to drop people off at various hotspots on the strip. It’s been active for a few years now and is expanding to other resorts, hotels, and destinations.
Currently, there are stops at three resorts: Westgate, the Encore, and Resorts World. However, there will eventually be “over 100 stations and span over 68 miles of tunnel,” the Vegas Loop website says.
The Loop utilizes Tesla Model 3 and Model Y vehicles to send passengers to their desired destinations. They are currently driven using the Full Self-Driving suite, but they also have safety drivers in each vehicle to ensure safety.
Tesla Cybertruck rides are crucial for Vegas Loop expansion to airport
Tesla and the Boring Company have been working to remove drivers from the vehicles used in the Loop, but now, it appears there is a set timeline to have them out, according to CEO Elon Musk:
The Tesla cars operating in The Boring Company tunnels under Las Vegas will be driverless in a month or two https://t.co/mX4nNrJui9

Musk says the Boring Co. will no longer rely on safety drivers within the Teslas for operation. Instead, Tesla will look to remove the safety drivers from the cars within the next month or two, a similar timeline for what Musk believes the Robotaxi platform will look like in Austin.
In Texas, as Robotaxi continues to operate as it has since June, there are still safety monitors within the car who sit in the passenger’s seat. They are there to ensure a safe experience for riders.
When the route takes the vehicle on the highway, safety monitors move into the driver’s seat.
However, Tesla wants to be able to remove safety monitors from its vehicles in Austin by the end of the year, Musk has said recently.
In early September, Musk said that the safety monitors are “just there for the first few months to be extra safe.” He then added that there “should be no safety driver by end of year.”
The safety driver is just there for the first few months to be extra safe.
Should be no safety driver by end of year.
