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.

Tesla tinkering with Speed Profiles on FSD v14.2.1 has gone too far
Tesla recently released Full Self-Driving (FSD) v14.2.1, its latest version, but the tinkering with Speed Profiles has perhaps gone too far.
We try to keep it as real as possible with Full Self-Driving operation, and we are well aware that with the new versions, some things get better, but others get worse. It is all part of the process with FSD, and refinements are usually available within a week or so.
However, the latest v14.2.1 update has brought out some major complaints with Speed Profiles, at least on my end. It seems the adjustments have gone a tad too far, and there is a sizeable gap between Profiles that are next to one another.
Tesla FSD v14.2.1 first impressions:
✅ Smooth, stress-free highway operation
✅ Speed Profiles are refined — Hurry seems to be limited to 10 MPH over on highways. Switching from Mad Max to Hurry results in an abrupt braking pattern. Nothing of concern but do feel as if Speed…— TESLARATI (@Teslarati) November 29, 2025
The gap is so large that changing between them presents a bit of an unwelcome and drastic reduction in speed, which is perhaps a tad too fast for my liking. Additionally, Speed Profiles seem to have a set Speed Limit offset, which makes it less functional in live traffic situations.
Before I go any further, I’d like to remind everyone reading this that what I am about to write is purely my opinion; it is not right or wrong, or how everyone might feel. I am well aware that driving behaviors are widely subjective; what is acceptable to one might be unacceptable to another.
Speed Profiles are ‘Set’ to a Speed
From what I’ve experienced on v14.2.1, Tesla has chosen to go with somewhat of a preset max speed for each Speed Profile. With ‘Hurry,’ it appears to be 10 MPH over the speed limit, and it will not go even a single MPH faster than that. In a 55 MPH zone, it will only travel 65 MPH. Meanwhile, ‘Standard’ seems to be fixed at between 4-5 MPH over.
This is sort of a tough thing to have fixed, in my opinion. The speed at which the car travels should not be fixed; it should be more dependent on how traffic around it is traveling.
It almost seems as if the Speed Profile chosen should be more of a Behavior Profile. Standard should perform passes only to traffic that is slower than the traffic. If traffic is traveling at 75 MPH in a 65 MPH zone, the car should travel at 75 MPH. It should pass traffic that travels slower than this.
Hurry should be more willing to overtake cars, travel more than 10 MPH over the limit, and act as if someone is in a hurry to get somewhere, hence the name. Setting strict limits on how fast it will travel seems to be a real damper on its capabilities. It did much better in previous versions.
Some Speed Profiles are Too Distant from Others
This is specifically about Hurry and Mad Max, which are neighbors in the Speed Profiles menu. Hurry will only go 10 MPH over the limit, but Mad Max will travel similarly to traffic around it. I’ve seen some people say Mad Max is too slow, but I have not had that opinion when using it.
In a 55 MPH zone during Black Friday and Small Business Saturday, it is not unusual for traffic around me to travel in the low to mid-80s. Mad Max was very suitable for some traffic situations yesterday, especially as cars were traveling very fast. However, sometimes it required me to “gear down” into Hurry, especially as, at times, it would try to pass slower traffic in the right lane, a move I’m not super fond of.
We had some readers also mention this to us:
The abrupt speed reduction when switching to a slower speed profile is definitely an issue that should be improved upon.

After switching from Mad Max to Hurry, there is a very abrupt drop in speed. It is not violent by any means, but it does shift your body forward, and it seems as if it is a tad drastic and could be refined further.

Tesla’s most affordable car is coming to the Netherlands
The trim is expected to launch at €36,990, making it the most affordable Model 3 the Dutch market has seen in years.
Tesla is preparing to introduce the Model 3 Standard to the Netherlands this December, as per information obtained by AutoWeek. The trim is expected to launch at €36,990, making it the most affordable Model 3 the Dutch market has seen in years.
While Tesla has not formally confirmed the vehicle’s arrival, pricing reportedly comes from a reliable source, the publication noted.
Model 3 Standard lands in NL
The U.S. version of the Model 3 Standard provides a clear preview of what Dutch buyers can expect, such as a no-frills configuration that maintains the recognizable Model 3 look without stripping the car down to a bare interior. The panoramic glass roof is still there, the exterior design is unchanged, and Tesla’s central touchscreen-driven cabin layout stays intact.
Cost reductions come from targeted equipment cuts. The American variant uses fewer speakers, lacks ventilated front seats and heated rear seats, and swaps premium materials for cloth and textile-heavy surfaces. Performance is modest compared with the Premium models, with a 0–100 km/h sprint of about six seconds and an estimated WLTP range near 550 kilometers.
Despite the smaller battery and simpler suspension, the Standard maintains the long-distance capability drivers have come to expect in a Tesla.
Pricing strategy aligns with Dutch EV demand and taxation shifts
At €36,990, the Model 3 Standard fits neatly into Tesla’s ongoing lineup reshuffle. The current Model 3 RWD has crept toward €42,000, creating space for a more competitive entry-level option, and positioning the new Model 3 Standard comfortably below the €39,990 Model Y Standard.
The timing aligns with rising Dutch demand for affordable EVs as subsidies like SEPP fade and tax advantages for electric cars continue to wind down, EVUpdate noted. Buyers seeking a no-frills EV with solid range are then likely to see the new trim as a compelling alternative.
With the U.S. variant long established and the Model Y Standard already available in the Netherlands, the appearance of an entry-level Model 3 in the Dutch configurator seems like a logical next step.

Tesla Model Y is still China’s best-selling premium EV through October
The premium-priced SUV outpaced rivals despite a competitive field, while the Model 3 also secured an impressive position.
The Tesla Model Y led China’s top-selling pure electric vehicles in the 200,000–300,000 RMB segment through October 2025, as per Yiche data compiled from China Passenger Car Association (CPCA) figures.
The premium-priced SUV outpaced rivals despite a competitive field, while the Model 3 also secured an impressive position.
The Model Y is still unrivaled
The Model Y’s dominance shines in Yiche’s October report, topping the chart for vehicles priced between 200,000 and 300,000 RMB. With 312,331 units retailed from January through October, the all-electric crossover was China’s best-selling EV in the 200,000–300,000 RMB segment.
The Xiaomi SU7 is a strong challenger at No. 2 with 234,521 units, followed by the Tesla Model 3, which achieved 146,379 retail sales through October. The Model Y’s potentially biggest rival, the Xiaomi YU7, is currently at No. 4 with 80,855 retail units sold.


Efficiency kings
The Model 3 and Model Y recently claimed the top two spots in Autohome’s latest real-world energy-consumption test, outperforming a broad field of Chinese-market EVs under identical 120 km/h cruising conditions with 375 kg payload and fixed 24 °C cabin temperature. The Model 3 achieved 20.8 kWh/100 km while the Model Y recorded 21.8 kWh/100 km, reaffirming Tesla’s efficiency lead.
The results drew immediate attention from Xiaomi CEO Lei Jun, who publicly recognized Tesla’s advantage while pledging continued refinement for his brand’s lineup.
“The Xiaomi SU7’s energy consumption performance is also very good; you can take a closer look. The fact that its test results are weaker than Tesla’s is partly due to objective reasons: the Xiaomi SU7 is a C-segment car, larger and with higher specifications, making it heavier and naturally increasing energy consumption. Of course, we will continue to learn from Tesla and further optimize its energy consumption performance!” Lei Jun wrote in a post on Weibo.
