The Tesla Semi’s 500 kWh battery and Convoy Mode are grossly underestimated
The Tesla Semi may be delayed for quite some time now, but it appears that Elon Musk’s all-electric Class 8 truck will be well worth the wait. And as the upcoming truck gets closer to mass production, it is becoming more and more evident that the Semi’s potential—particularly with regards to its batteries and FSD features—remains grossly underestimated.
During a recent appearance at the Joe Rogan Experience podcast, Elon Musk revealed that the Semi would be equipped with a 500 kWh battery pack. The Tesla CEO did not specify which variant of the Semi will be fitted with a 500 kWh pack, though speculations from the electric vehicle community suggest that the battery would be for the truck’s 300-mile variant. However, even if this were the case, such an update provides a glimpse at just how far Tesla has come when it comes to its battery technology.
“You want something in the order of probably a 500 kWh pack. What we have in the Model S and X is a 100 kWh pack and probably something like a 500 kWh pack in the Tesla Semi,” Musk said.
When the Semi was unveiled in late 2017, Tesla noted that the vehicle would consume less than 2 kWh per mile. Considering that the Tesla Semi’s two variants are listed with 300 and 500 miles of range, estimates pointed to the vehicle having a battery pack that’s likely around 600 kWh to 1,000 kWh. Musk’s recent update suggests that Tesla has improved its batteries to such a degree that the Semi now needs a smaller battery pack to accomplish its 300-mile range target. This may seem like a minor change, but a smaller battery pack presents numerous advantages, such as lower weight and significant production cost savings. These all contribute to make the 300-mile Tesla Semi a viable and competitive vehicle, especially considering its estimated $150,000 base price.
Of course, these advantages only become more prominent if one considers the benefits of Tesla’s structural 4680 battery packs. With structural batteries in place, the Semi could save weight and production costs even further. A structural battery could also make the Semi more rigid, allowing it to be even safer than its initial iterations. This goes hand in hand with another update on the vehicle that was mentioned by Tesla, and one that is also widely ignored or at most underestimated today.
During Tesla’s Q4 FY 2020 earnings call, Elon Musk confirmed that the Semi might very well be the first vehicle in the company’s lineup that would receive full autonomy features. This was a point highlighted by both Elon Musk and Automotive President Jerome Guillen, who noted that the FSD hardware on the Semi would be the same one used in Tesla’s other vehicles. Musk, for his part, pointed out that the Semi’s FSD features will require Tesla to modify the FSD software’s parameters according to the Semi’s large size.
Perhaps one thing that is rarely mentioned is that when the Semi was unveiled in 2017, Elon Musk remarked that the vehicle was already capable of utilizing a feature called “Convoy Mode,” which optimizes efficiency while allowing several uncrewed trucks to follow a lead, crewed vehicle. If Musk’s statements were accurate and Convoy Mode was already feasible with Enhanced Autopilot’s capabilities in late 2017, then such a function would likely be extremely plausible today with the Full Self-Driving Beta. This should make the Semi safer to use than traditional long-haulers, most of whom are still manually driven. Couple this with the Semi’s functions like its four electric motors, which help prevent incidents like jackknifing, and the upcoming all-electric Class 8 truck has a shot at becoming one of the safest large vehicles on the road today.

Electric vehicle maker Lucid Group has denied rumors of an imminent bankruptcy after a report from this morning sent the stock on a dramatic drop on Wall Street, seeing losses of more than 40 percent during trading hours.
Lucid’s Director of Communications, Nick Twork, responded to the report from Eletric-Vehicles.com, which stated the company’s restructuring advisor, AlixPartners, was asked to review two decisions: taking Lucid shares private or filing for Chapter 11 bankruptcy protection.
The report also claims AlixPartners told the Lucid board to “concentrate on Gravity production while improving its quality, and to temporarily hold back the Lucid Air, the sedan that has defined the company since its launch.”
Twork said:
$LCID The rumors are completely false. The company has sufficient liquidity to carry its operations well into next year, as recently published in its last quarterly filings, and it has not formed any special Board committee to explore the scenarios reported today. Our focus is…

Shares rebounded after the response to the report, halving its losses as the trading day neared 3 p.m. Eastern.
Lucid has struggled to get its sales off the ground and into more respectable numbers, but the company is in its early years, when things are hard to begin with. It is also backed by several notable investors, including the Saudi Public Investment Fund (PIF), which has nearly limitless money and likely would not ditch an investment of this size so soon.
Lucid shares were down just 14 percent at the time of publication, a far cry from the 55 percent its losses topped out at during the day.
A Tesla owner who purchased a Model S Signature Edition, one of the final 250 units of the all-electric flagship vehicle that the company discontinued earlier this year, is attempting to sell the car despite a no-resale clause that prohibits reselling for the first year.
The car is being sold by J&S Autohaus in Ewing, New Jersey, and is priced at $260,490, well above the $159,420 that Tesla sold it for earlier this year.

To those who do not know, the Model S Signature was a highly exclusive, limited-run farewell variant of the Model S Plaid that was produced this year to mark the end of production of both the Model S and Model X, Tesla’s two flagship vehicles.
Limited to just 250 units with invite-only sales, it serves as a collector’s item celebrating the legacy of the Model S, which helped pioneer Tesla’s electric vehicle success since its 2012 launch.
It bundles top-tier performance with bespoke cosmetic and luxury upgrades, plus Tesla’s Luxe Package. Here’s what the Model S Signature has over the typical Model S Plaid:
- Exclusive Exterior – Unique Garnet Red Paint, matching door handles, gold Tesla “T” badges upfront, gold Plaid and Signature badging at the rear.
- Premium Interior – White Alcantara upholstery with gold piping/accents, gold Plaid seat badges, Signature-marked door sills, individually numbered dashboard plaque, gold puddle lights, special interior lighting sequence, and a custom Signature key fob.
- Performance Upgrades – Carbon-ceramic brakes with gold calipers
- Bundled Luxe Package – Full Self-Driving (Supervised), four years of Premium Connectivity, free lifetime Supercharging
- Performance Metrics – ~1,020 horsepower, sub-2-second 0-60 MPH, ~390-mile range
Tesla quickly introduced a No Resale Agreement for the Signature Editions of the Model S and Model X, which would penalize the seller for “the amount of $50,000 or the value received as consideration for the sale or transfer, whichever is greater.”
The company continues:
“If you sell or otherwise transfer the ownership of your Model S or Model X, the remainder of the Recommended Maintenance, Wheel and Tire Protection Plan, and Windshield Protection Plan will transfer automatically to the buyer. The Full Self-Driving (Supervised), Free Supercharging and Premium Connectivity will not transfer with the vehicle and will terminate once the ownership of the Model S or Model X is transferred.”
Tesla will likely come after the seller, especially as it has been about two months since Tesla launched deliveries.
Tesla rolled out Full Self-Driving (Supervised) v14.3.5 yesterday, and about fifty miles of driving on the new version has given me enough time to highlight what seems to be strong about the release and what is not.
Additionally, Tesla has added a few new features with this specific update, which we’ll highlight as well.
Tesla Full Self-Driving v14.3.5 Performance
The new update is business as usual. Things seem to be running completely normal and necessary, but there are a few things that we’ve seemed to pick up on based on our own experience with v14.3.5, as well as what other users are seeing.
Initially, it seems to be more aware of its surroundings, making moves that are incredibly courteous to other drives and operating just a tad more reserved than what the suite might have done previously.
We had two instances where it showed this, the first being FSD needing to pass a Flagger Force vehicle that was placing down signage for the day. Their work truck was right at the front corner of a right-hand turn; typically where most cars travel when they take that turn.
FSD v14.3.5 recognized this, slowed down, and took the turn wide with no issues:

Additionally, v14.3.5 backed up for a semi truck that was making a wide turn onto a road my car was on. This is not new, but it seemed to be backing up for courtesy; it didn’t seem completely necessary, but it might have put some peace of mind in the truck driver’s head:

X user Mike P, also a Pennsylvania native like myself, shared three clips of his Tesla running v14.3.5 performing similar maneuvers. He said:
“FSD turns right into a small alley that only fits one car at a time, sees oncoming car, reverses out of alley to make space, realizes oncoming car is actually parking, re-enters alley.”

It seems like Speed Profiles are still in need of some tweaking; I am adjusting what Speed Profile I’m in frequently, constantly changing it to get it to travel at the correct speed. This was an issue for me on v14.3.4. It seems like they’re just a little inconsistent.
Terrible Parking
Parking attempts on v14.3.5 were not good. There are quite a few people who have said this:
Yeah it seems like FSD v14.3.5 is having some issues with parking early on https://t.co/Bw5ULfVmDq pic.twitter.com/RHdpjOEpIo

David Moss, the Tesla owner who has taken multiple coast-to-coast drives without any interventions, also has had some issues with parking early on with v14.3.5:

New Features
Tesla has added the ability to open Camera Preview at any time. Previously, it was only available in Park. Here’s what that feature looks like in action:
