When the Tesla Semi was unveiled back in late 2017, many were skeptical. A Daimler executive even went so far as to sarcastically comment that the massive all-electric vehicle defies the laws of physics. Doubts were abounding about whether the Semi would be able to haul any meaningful cargo since its batteries would be extremely heavy, or if the truck could achieve its target 500-mile range.
These questions were addressed during Tesla’s Q3 2022 earnings call. While discussing the Semi, Elon Musk clarified that the Class 8 all-electric truck’s 500-mile range estimate refers to the truck when it’s traveling with cargo. This suggests that Tesla has already been able to optimize the Semi’s weight to a point where it could carry close to the same amount of cargo as traditional diesel tractor-trailers.
“We will begin ramping up production of the Tesla Semi. No sacrifice to cargo capacity, 500-mile range. Just to be clear, 500 miles with the cargo on level ground,” Musk said, though he also noted that the vehicle should achieve this range if it was traveling on level ground. If the Semi is traveling up inclines, then its range would likely be adjusted.
Musk also addressed the skepticism that has surrounded the Semi. Musk mentioned that he had encountered people who believe it’s impossible to make long-range battery-electric trucks, but when asked for details, the CEO noted that he had not encountered a legitimate argument about how battery-electric trucks are not viable. Musk also poked fun at hydrogen trucks, which he noted are not really needed.
“But the point is, it’s a long-range truck and even with heavy cargo. And the number of times people tell, ‘No, you can’t — it’s impossible to make a long-range heavy-duty Class 8 truck.’
“And then, I’ll ask, well, what are your assumptions about what… hours per mile, and they look at me with a blank stare and then say hydrogen. I’m like, ‘No, that’s not the answer.’ I was looking for numbers, literally. It’s not a number. You obviously don’t need hydrogen for a heavy truck.”
The Tesla Semi is expected to start deliveries on December 1, 2022. Initial production of the Tesla Semi units will be delivered to Pepsi, which has already been setting up some of its facilities, such as its Modesto, California site, with Megachargers that will be capable of charging the all-electric Class 8 truck in a rapid manner.

Analyst consensus for Q4 has Tesla earnings per share falling 38% to $0.45 with revenue declining 4% to $24.74 billion, as per estimates from FactSet. In comparison, the consensus compiled by Tesla last week forecasted $0.44 per share on sales totaling $24.49 billion.
For FY 2025, Tesla posted GAAP EPS of $1.08 and non-GAAP EPS of $1.66 per share. Tesla also posted total revenues of $94.827 billion, which include $69.526 billion from automotive and $12.771 billion from the battery storage business. GAAP net income is also listed at $3.794 billion in FY 2025.
xAI Investment
On January 16, 2026, Tesla agreed to invest approximately $2 billion to acquire Series E preferred shares in xAI as part of the company’s recently disclosed financing round. Tesla said the investment was made on market terms consistent with those agreed to by other participants in the round.
The investment aligns with Tesla’s strategy under Master Plan Part IV, which centers on bringing artificial intelligence into the physical world through products and services. While Tesla focuses on real-world AI applications, xAI is developing digital AI platforms, including its Grok large language model.

TSLA-Q4-2025-Update by Simon Alvarez
Tesla has rolled out a new Supercharging safety feature in the United States, one that will answer concerns that some owners may have if they need to leave in a pinch.
It is also a suitable alternative for non-Tesla chargers, like third-party options that feature J1772 or CCS to NACS adapters.
The feature has been available in Europe for some time, but it is now rolling out to Model 3 and Model Y owners in the U.S.
With Software Update 2026.2.3, Tesla is launching the Unlatching Charge Cable function, which will now utilize the left rear door handle to release the charging cable from the port. The release notes state:
“Charging can now be stopped and the charge cable released by pulling and holding the rear left door handle for three seconds, provided the vehicle is unlocked, and a recognized key is nearby. This is especially useful when the charge cable doesn’t have an unlatch button. You can still release the cable using the vehicle touchscreen or the Tesla app.”
The feature was first spotted by Not a Tesla App.
This is an especially nice feature for those who commonly charge at third-party locations that utilize plugs that are not NACS, which is the Tesla standard.
For example, after plugging into a J1772 charger, you will still be required to unlock the port through the touchscreen, which is a minor inconvenience, but an inconvenience nonetheless.
Additionally, it could be viewed as a safety feature, especially if you’re in need of unlocking the charger from your car in a pinch. Simply holding open the handle on the rear driver’s door will now unhatch the port from the car, allowing you to pull it out and place it back in its housing.
This feature is currently only available on the Model 3 and Model Y, so Model S, Model X, and Cybertruck owners will have to wait for a different solution to this particular feature.

LG Energy Solution pursuing battery deal for Tesla Optimus, other humanoid robots: report
Optimus is expected to be one of Tesla’s most ambitious projects, with Elon Musk estimating that the humanoid robot could be the company’s most important product.
A recent report has suggested that LG Energy Solution is in discussions to supply batteries for Tesla’s Optimus humanoid robot.
Optimus is expected to be one of Tesla’s most ambitious projects, with Elon Musk estimating that the humanoid robot could be the company’s most important product.
Humanoid robot battery deals
LG Energy Solution shares jumped more than 11% on the 28th after a report from the Korea Economic Daily claimed that the company is pursuing battery supply and joint development agreements with several humanoid robot makers. These reportedly include Tesla, which is developing Optimus, as well as multiple Chinese robotics companies.
China is already home to several leading battery manufacturers, such as CATL and BYD, making the robot makers’ reported interest in LG Energy Solution quite interesting. Market participants interpreted the reported outreach as a signal that performance requirements for humanoid robots may favor battery chemistries developed by companies like LG.
LF Energy Solution vs rivals
According to the report, energy density is believed to be the primary reason humanoid robot developers are evaluating LG Energy Solution’s batteries. Unlike electric vehicles, humanoid robots have significantly less space available for battery packs while requiring substantial power to operate dozens of joint motors and onboard artificial intelligence processors.
LG Energy Solution’s ternary lithium batteries offer higher energy density compared with rivals’ lithium iron phosphate (LFP) batteries, which are widely used by Chinese EV manufacturers. That advantage could prove critical for humanoid robots, where runtime, weight, and compact packaging are key design constraints.
