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.

Elon Musk reveals date of Tesla Full Self-Driving’s next massive release
Initially planned for a January or February release, v14.3 aims to add some reasoning and logic to the decisions that Full Self-Driving makes, which could improve a lot of things, including Navigation, which is a major complaint of many owners currently.
Tesla CEO Elon Musk revealed the date of Full Self-Driving’s next massive release: v14.3.
For months, Tesla owners with Hardware 4 have been utilizing Full Self-Driving v14.2 and subsequent releases. Currently, the most up-to-date FSD version is v14.2.2.5, which has definitely brought out mixed reviews. With releases, some things get better, and other things might regress slightly.
For the most part, things are better in terms of overall behavior.
However, many owners have been looking forward to the next release, which is v14.3, about which Musk has said many great things. Back in November, Musk said that v14.3 “is where the last big piece of the puzzle lands.”
He added:
“We’re gonna add a lot of reasoning and RL (reinforcement learning). To get to serious scale, Tesla will probably need to build a giant chip fab. To have a few hundred gigawatts of AI chips per year, I don’t see that capability coming online fast enough, so we will probably have to build a fab.”

Tesla Full Self-Driving v14.2 is a considerable improvement from early versions of the suite, but we have written about the somewhat confusing updates that have come with recent versions.
Tesla Full Self-Driving v14.2.2.5 might be the most confusing release ever
They’ve been incredibly difficult to gauge in terms of progress because some things have gotten better, but there seems to be some real regression on a handful of things, especially with confidence and assertiveness.
Musk confirmed today on X that Tesla is already testing v14.3 internally right now. It will hit a wide release “in a few weeks,” so we should probably expect it by late April.
It’s in testing right now. Wide release in a few weeks.

Overall, there are high hopes that v14.3 could be a true game changer for Tesla Full Self-Driving, as many believe it could be the version that Robotaxis in Austin, Texas, some of which are driverless and unsupervised, are running.
It could also include some major additions, including “Banish,” also referred to as “Reverse Summon,” which would go find a parking spot after dropping occupants off at their destination.
What Tesla will roll out, and when exactly it arrives, all remain to be seen, but fans have been ready for a new version as v14.2.2.5 has definitely run its course. We have had a lot of readers tell us their biggest request is to fix Navigation errors, which seem to be one of the most universal complaints among daily FSD users.

Tesla Full Self-Driving gets latest bit of scrutiny from NHTSA
The analysis impacts roughly 3.2 million vehicles across the company’s entire lineup, and aims to identify how the suite’s degradation detection systems work and how effective they are when the cars encounter difficult visibility conditions.
The National Highway Traffic Safety Administration (NHTSA) has elevated its probe into Tesla’s Full Self-Driving (Supervised) suite to an Engineering Analysis.
The analysis impacts roughly 3.2 million vehicles across the company’s entire lineup, and aims to identify how the suite’s degradation detection systems work and how effective they are when the cars encounter difficult visibility conditions.
The step up into an Engineering Analysis is often required before the NHTSA will tell an automaker to issue a recall. However, this is not a guarantee that a recall will be issued.

The NTHSA wants to examine Tesla FSD’s ability to assess road conditions that have reduced visibility, as well as detect degradation to alert the driver with sufficient time to respond.
The Office of Defects Investigation (ODI) will evaluate the performance of FSD in degraded roadway conditions and the updates or modifications Tesla makes to the degradation detection system, including the timing, purpose, and capabilities of the updates.
Tesla routinely ships software updates to improve the capabilities of the FSD suite, so it will be interesting to see if various versions of FSD are tested. Interestingly, you can find many examples from real-world users of FSD handling snow-covered roads, heavy rain, and single-lane backroads.
However, there are incidents that the NHTSA has used to determine the need for this probe, at least for now. The agency said:
“Available incident data raise concerns that Tesla’s degradation detection system, both as originally deployed and later updated, fails to detect and/or warn the driver appropriately under degraded visibility conditions such as glare and airborne obscurants. In the crashes that ODI has reviewed, the system did not detect common roadway conditions that impaired camera visibility and/or provide alerts when camera performance had deteriorated until immediately before the crash occurred.”
It continues to say in its report that a review of Tesla’s responses revealed additional crashes that occurred in similar environments showed FSD “did not detect a degraded state, and/or it did not present the driver with an alert with adequate time for the driver to react. In each of these crashes, FSD also lost track of or never detected a lead vehicle in its path.”
The next steps of the NHTSA Engineering Analysis require the agency to gather further information on Tesla’s attempts to upgrade the degradation detection system. It will also analyze six recent potentially related incidents.
The investigation is listed as EA26002.
