The Tesla Semi has now been tested by a few different companies, and recent client DHL has just shared its results from a two-week trial period with the Class 8 truck, noting that it significantly outperformed the company’s expectations.

On its website, DHL has posted initial results from a two-week testing period with the Tesla Semi, in which it drove the electric Class 8 truck over 3,000 miles of its normal operating routes based in Livermore, California. Part of the trial included a 390-mile haul with the Semi fully loaded with a gross combined weight of 75,000 pounds, which the company says confirmed the electric vehicle’s (EV’s) ability to haul “typical DHL payloads over a long distance on a single charge.”

Impressively, DHL says that, for more than half the time the crew drove the Semi, it averaged 1.72 kWh per mile when operating at speeds exceeding 50 mph (80 km/h). As the company notes, this went way beyond DHL’s expectations as well as Tesla’s own rating for the Semi.

On its website, Tesla says the Semi can achieve a driving efficiency of “under 2 kWh” of energy consumption per mile with a total full-load range of 300 or 500 miles. The Semi also has a battery pack of around 900 kWh.

“Maximizing range and efficiency is crucial to proving that long-haul electric vehicles can perform equivalent work to diesel,” writes Graham Caroll, DHL’s Head of Business Development for semi-trucks. “We’re excited to see DHL confirm the benefits of the Semi’s advanced technology and driver-centric features in live commercial operations.”

Following the trial, DHL says it’s now evaluating how to integrate the Semis into its fleet when Tesla begins volume production of the Semi at an upcoming Gigafactory Nevada facility in 2026.

The trial also comes as the latest in a series of companies sharing early testing results for the Semi. The first company to get access to Tesla’s Semis was PepsiCo, and it’s currently operating the vehicles out of hubs in Modesto, Sacramento, and Fresno, California. PepsiCo’s early performance results with the Semi also showed promising efficiency results.

During the IAA trucking conference in Münich, Germany last month, Tesla Semi Engineering Head Dan Priestley also shared a few additional details about the Semi’s early fleet data. One of the highlights from his presentation was that the Semi pilot fleet so far has a 95-percent uptime including scheduled and unscheduled maintenance.

Additionally, Priestley said that more than 4.65 million miles have been driven since the Semi pilot programs began, while one single Semi unit alone has driven over 248,000 miles after just 18 months.

Tesla Cybercab undergoes winter testing as Elon Musk reiterates production start date

CEO Elon Musk confirmed the timeline in a recent post on X, while Tesla’s official social media accounts separately revealed that Cybercab prototypes are now undergoing winter testing in Alaska.

Tesla has reiterated that production of its fully autonomous Cybercab is set to begin in April, even as the company continues expanding real-world testing of the vehicle. 

CEO Elon Musk confirmed the timeline in a recent post on X, while Tesla’s official social media accounts separately revealed that Cybercab prototypes are now undergoing winter testing in Alaska.

Musk confirms April Cybercab initial production

In a post on X, Musk reiterated that Cybercab production is scheduled to begin in April, reiterating his guidance about the vehicle’s manufacturing timeline. Around the same time, Tesla shared images showing the Cybercab undergoing cold-weather testing in Alaska. Interestingly enough, the Cybercab prototypes being tested in Alaska seemed to be equipped with snow tires. 

Winter testing in Alaska suggests Tesla is preparing the Cybercab for deployment across a wide range of climates in the United States. Cold temperatures, snow, ice, and reduced traction present some of the most demanding scenarios for autonomous systems, making Alaska a logical proving ground for a vehicle designed to operate without a human driver.

Taken together, Musk’s production update and Tesla’s testing post indicate that while the Cybercab is nearing the start of manufacturing, validation efforts are still actively ramping to ensure reliability in real-world environments.

What early Cybercab production might look like

Musk has previously cautioned that the start of Cybercab manufacturing will be slow, reflecting the challenges of launching an all-new vehicle platform. In a recent comment, Musk said initial production typically follows an S-curve, with early output constrained by how many new parts and processes are involved.

According to Musk, both Cybercab and Optimus fall into this category, as “almost everything is new.” As a result, early production rates are expected to be very deliberate before eventually accelerating rapidly as manufacturing processes mature.

“Initial production is always very slow and follows an S-curve. The speed of production ramp is inversely proportionate to how many new parts and steps there are. For Cybercab and Optimus, almost everything is new, so the early production rate will be agonizingly slow, but eventually end up being insanely fast,” Musk wrote in a post on X.

Tesla to increase Full Self-Driving subscription price: here’s when

Published

Tesla will increase its Full Self-Driving subscription price, meaning it will eventually be more than the current $99 per month price tag it has right now.

Already stating that the ability to purchase the suite outright will be removed, Tesla CEO Elon Musk said earlier this week that the Full Self-Driving subscription price would increase when its capabilities improve:

“I should also mention that the $99/month for supervised FSD will rise as FSD’s capabilities improve. The massive value jump is when you can be on your phone or sleeping for the entire ride (unsupervised FSD).”

This was an expected change, especially as Tesla has been hinting for some time that it is approaching a feature-complete version of Full Self-Driving that will no longer require driver supervision. However, with the increase, some are concerned that they may be priced out.

$99 per month is already a tough ask for some. While Full Self-Driving is definitely worth it just due to the capabilities, not every driver is ready to add potentially 50 percent to their car payment each month to have it.

While Tesla has not revealed any target price for FSD, it does seem that it will go up to at least $150.

Additionally, the ability to purchase the suite outright is also being eliminated on February 14, which gives owners another reason to be slightly concerned about whether they will be able to afford to continue paying for Full Self-Driving in any capacity.

Some owners have requested a tiered program, which would allow people to pay for the capabilities they want at a discounted price.

Unsupervised FSD would be the most expensive, and although the company started removing Autopilot from some vehicles, it seems a Supervised FSD suite would still attract people to pay between $49 and $99 per month, as it is very useful.

Tesla will likely release pricing for the Unsupervised suite when it is available, but price increases could still come to the Supervised version as things improve.

This is not the first time Musk has hinted that the price would change with capability improvements, either. He’s been saying it for some time. In 2020, he even said the value of FSD would “probably be somewhere in excess of $100,000.”

Tesla starts removing outright Full Self-Driving purchase option at time of order

Published

Tesla has chosen to axe the ability to purchase Full Self-Driving outright from a select group of cars just days after CEO Elon Musk announced the company had plans to eliminate that option in February.

The company is making a clear-cut stand that it will fully transition away from the ability to purchase the Full Self-Driving suite outright, a move that has brought differing opinions throughout the Tesla community.

Earlier this week, the company also announced that it will no longer allow buyers to purchase Full Self-Driving outright when ordering a pre-owned vehicle from inventory. Instead, that will be available for $99 per month, the same price that it costs for everyone else.

The ability to buy the suite for $8,000 for a one-time fee at the time of order has been removed:

This is a major move because it is the first time Tesla is eliminating the ability to purchase FSD outright for one flat fee to any of its vehicles, at least at the time of purchase.

It is trying to phase out the outright purchase option as much as it can, preparing people for the subscription-based service it will exclusively offer starting on February 14.

In less than a month, it won’t be available on any vehicle, which has truly driven some serious conversation from Tesla owners throughout the community.

There’s a conflict, because many believe that they will now lose the ability to buy FSD and not pay for it monthly, which is an attractive offer. However, others believe, despite paying $8,000 for FSD, that they will have to pay more money on top of that cost to get the unsupervised suite.

Additionally, CEO Elon Musk said that the FSD suite’s subscription price would increase over time as capabilities increase, which is understandable, but is also quite a conflict for those who spent thousands to have what was once promised to them, and now they may have to pay even more money.
