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.

A probe into a popular Tesla self-driving feature has been closed by the National Highway Traffic Safety Administration (NHTSA) after over a year of scrutiny from the government agency.

The NHTSA has officially closed its investigation into Tesla’s Actually Smart Summon (ASS) feature, marking a regulatory win for the electric vehicle maker after more than a year of scrutiny.

Here’s our coverage on the launch of the probe:

The preliminary investigation, opened last January, examined roughly 2.59 million Tesla vehicles equipped with the feature across the Model S, Model X, Model 3, and Model Y lineups. ASS is not available for Cybertruck currently.

Actually Smart Summon allows owners to move their parked Tesla via a smartphone app remotely, directing the vehicle short distances in parking lots or private property while the driver supervises from the phone.

Here’s a clip of us using it:

Introduced as an upgrade to the original Smart Summon, the feature was designed to enhance convenience but drew attention after reports of low-speed incidents where vehicles bumped into stationary objects like posts, parked cars, or garage doors.

The NHTSA’s Office of Defects Investigation reviewed 159 incidents, including one formal Vehicle Owner’s Questionnaire complaint and media reports.

Notably, all events occurred at very low speeds, resulted only in minor property damage, and involved zero injuries or fatalities. The agency determined that the incidents were “extremely rare”, a fraction of one percent across millions of Summon sessions, and did not indicate a systemic safety-related defect.

A key factor in the closure was Tesla’s proactive response through over-the-air (OTA) software updates.

During the probe, Tesla deployed at least six updates that improved camera-based object detection, enhanced neural network performance for obstacle recognition, and refined the system’s response to potential hazards. These iterative improvements, delivered wirelessly to the entire fleet, addressed the primary concerns around detection reliability and operator reaction time.

Critics of Tesla’s autonomous features had initially pointed to the crashes as evidence of rushed deployment, especially given the feature’s reliance on the company’s vision-only Full Self-Driving (FSD) stack. However, NHTSA’s decision to close the case without seeking a recall underscores the low-severity nature of the events and the effectiveness of software-based fixes in modern vehicles.

It definitely has its flaws. I used ASS yesterday unsuccessfully:

However, improvements will come, and I’m confident in that.

The closure comes as Tesla continues to push boundaries with its autonomous driving ambitions, including unsupervised FSD rollouts and robotaxi initiatives. For owners, the ruling reinforces confidence in Actually Smart Summon as a convenient, low-risk tool rather than a hazardous experiment.

While broader NHTSA reviews of Tesla’s higher-speed FSD capabilities remain ongoing, this outcome highlights how data-driven analysis and rapid OTA remediation can satisfy regulators in the evolving landscape of automated driving technology.

Tesla has not issued an official statement on the closure, but the move is widely viewed as bullish for the company’s autonomy roadmap, reducing one layer of regulatory overhang and allowing focus on further refinements.

Tesla uses Model S and X ‘sentimental’ value to enforce massive pricing move

By slashing production and creating immediate scarcity, the company has transformed these remaining vehicles into limited-edition relics. The price hike is not driven by rising material costs or new features.

Tesla is using the “sentimental” value that CEO Elon Musk talked about with the Model S and Model X to enforce one of the most massive pricing moves it has ever applied as it begins to phase out the flagship vehicles.

Tesla quietly executed one of its most calculated pricing plays yet. After officially ending production of the Model S and Model X, the company raised prices on every remaining new and demo unit by roughly $15,000.

The refreshed starting prices now sit at:

  • $109,990 for the Model S AWD
  • $124,900 for the Model S Plaid
  • $114,900 for the Model X AWD
  • $129,900 for the Model X Plaid

Every vehicle comes fully loaded with the Luxe Package, Full Self-Driving Supervised, four years of premium connectivity and service, and lifetime free Supercharging. What looks like a simple inventory adjustment is, in reality, a masterclass in monetizing nostalgia.

These are not ordinary cars. For many owners, the Model S and Model X represent the purest expression of Tesla’s original promise—the sleek, over-engineered flagships that proved electric vehicles could be faster, quieter, and more desirable than their gasoline counterparts.

They are the vehicles that carried Elon Musk’s vision from Silicon Valley startup to global automaker.

The final units rolling off the line carry an emotional weight that numbers alone cannot capture. Buyers are not simply purchasing transportation; they are acquiring a piece of Tesla history, the last examples of the very models that defined the brand’s first decade.

Tesla, with this move, understands this sentiment deeply.

By slashing production and creating immediate scarcity, the company has transformed these remaining vehicles into limited-edition relics. The price hike is not driven by rising material costs or new features.

It is driven by the knowledge that a certain segment of buyers, loyalists, collectors, and enthusiasts, will pay a premium precisely because these cars are about to disappear. The strategy converts emotional attachment into margin.

Where other automakers might discount outgoing models to clear lots, Tesla is betting that sentiment is worth more than volume.

The move also quietly rewards existing owners. Scarcity instantly boosts resale values for the hundreds of thousands of Model S and X already on the road, reinforcing brand loyalty among the very people who helped build Tesla’s reputation.

In the end, Tesla’s pricing decision reveals a sophisticated understanding of its audience. As the company pivots toward next-generation platforms, it has found a way to extract one final, lucrative chapter from its heritage.

For buyers willing to pay the new prices, the premium is not just for the car; it is for the feeling of owning the last true originals. Tesla has turned sentiment into strategy, and in the process, reminded everyone that even in the EV era, emotion remains a powerful line on the balance sheet.

Tesla has broadened the availability of the most-wanted Model Y trim to eight new Asian markets, expanding the footprint of what is one of the most highly requested vehicle configurations in the U.S.

Tesla has officially launched ordering for the Model Y L, its long-wheelbase six-seater electric SUV, across eight key Asian territories: Japan, South Korea, Hong Kong, Macau, Singapore, Thailand, Malaysia, and the Philippines.

The announcement signals a major expansion for the family-oriented variant first introduced in China in August 2025. In Thailand, Malaysia, and the Philippines, the vehicle had already been previewed at several motor shows, so fans in the area were familiar with the Model Y L and its distinct differences to the standard-sized trims.

Local pricing reflects taxes, incentives, and import duties. Malaysia estimates RM260,000 with Q2 2026 deliveries; Singapore lists S$248,999 (including COE); Macau prices at 398,750 patacas. Similar competitive positioning is expected in Japan, South Korea, Hong Kong, Thailand, and the Philippines, where the Model Y L undercuts many traditional three-row SUVs while offering full EV benefits.

Notably, the Model Y L remains unavailable in the U.S. market, where demand for a stretched Model Y has been high. Although CEO Elon Musk said that something “way cooler than a minivan” is on the way in the U.S., the dimensions of the Model Y L simply fit the needs of many American families.

Elon Musk says Tesla is developing a new vehicle: ‘Way cooler than a minivan’

The Model Y L stands out with its stretched dimensions: 4,976 mm long and a 3,040 mm wheelbase—179 mm and 150 mm longer, respectively, than the standard Model Y. Height increases slightly to 1,668 mm, creating a true three-row, 2+2+2 layout with individual captain’s chairs in the second row for easier third-row access.

Maximum cargo capacity reaches 2,539 liters with seats folded, making it ideal for growing families or those needing versatile space in dense urban environments. But it’s not just a grocery-getter or a kid-hauler: The performance matches Tesla’s reputation.

Dual-motor all-wheel drive delivers 0-100 km/h acceleration in about 5.0 seconds (or 4.5 seconds in some market specs), with a top speed of 201 km/h. The vehicle boasts a WLTP-rated range of up to 681 km, supported by an approximately 88-97 kWh battery pack (market-dependent) and 250 kW DC fast charging.

With deliveries slated for Q2 2026 and strong early interest mirroring China’s rapid pre-orders, the Model Y L could become a bestseller in these dynamic markets. Tesla’s targeted expansion essentially generalizes its commitment to tailoring vehicles to regional needs while advancing sustainable mobility across Asia.
