While undergoing its commissioning process in late September, a fire broke out in one of the Tesla Megapacks at the Bouldercombe big battery in Queensland, Australia. The fire triggered debates about the viability of renewable energy solutions, as well as the safety of battery storage systems. 

The fire was not severe, with Genex Power, the owner of the battery storage system, stating that the fire did not even necessitate the use of water at all. Genex CEO Craig Francis also noted that the isolated nature of the fire suggests that the incident would not have any significant impact on the Bouldercombe big battery. 

And as per an announcement from Genex Power, the fire actually did not start at the Megapack’s battery modules. Instead, the fault initially occurred on the AC side of the impacted Megapack unit. The fault then propagated to the battery modules within the Megapack. This was determined following an analysis of the incident by Tesla, Genex, and other stakeholders.

Genex described the findings of the Megapack battery fire analysis in its announcement

“The preliminary RCA indicates that a fault occurred on the AC side of the Megapack unit. The fault then propagated to the battery modules within the Megapack. The burn of the Megapack followed design and certification testing expectations under UL9540A, with no external water required, and no propagation of the active fire to adjacent Megapack units or balance of plant.

“The failure has been isolated to the power electronics interface with the AC bus bar in the individual Megapack unit itself and not the broader installation of Megapack units. In order to mitigate against a further event, Tesla will be undertaking replacement of two identified power electronics units and out of caution, physical inspection of the power electronics within the remainder of units at the Project site. Genex will also be implementing upgrades to breaker control setting response times to further mitigate against a potential future event,” Genex wrote.

While the minor fire affected one Megapack battery in the Bouldercombe site, the Megapack adjacent to the impacted unit also suffered minor thermal damage to its electrical insulation. Thus, Tesla would be providing two Megapacks to replace the two units that were damaged by the fire. The Megapacks are already en route to the site, and are expected to arrive in early December 2023, as noted in a PV Magazine Australia report.

Xpeng CEO He Xiaopeng has offered fresh praise for Tesla’s Full Self-Driving (FSD) system after revisiting Silicon Valley more than a year after his first hands-on experience. 

Following extended test drives of Tesla vehicles running the latest FSD software, He stated that the system has made major strides, reinforcing his view that Tesla’s approach to autonomy is indeed the proper path towards autonomy.

Tesla FSD closing in on Level 4 driving

During his visit, He test-drove a Tesla equipped with FSD V14.2. He also rode in a Tesla Robotaxi. Over roughly five hours of driving across Silicon Valley and San Francisco, He said both vehicles delivered consistent and reassuring performance, a notable improvement from his experience a year earlier.

According to He, Tesla’s FSD has evolved from a smooth Level 2 advanced driver assistance system into what he described as a “near-Level 4” experience in terms of capabilities. While acknowledging that imperfections remain, the Xpeng CEO said FSD’s current iteration significantly surpasses last year’s capabilities. He also reiterated his belief that Tesla’s strategy of using the same autonomous software and hardware architecture across private vehicles and robotaxis is the right long-term approach, allowing users to bypass intermediate autonomy stages and move closer to Level 4 functionality.

He previously tested Tesla’s FSD V12.3.6 and Waymo vehicles in California in mid-2024, noting at the time that Waymo performed better in dense urban environments like San Francisco, while Tesla excelled in Silicon Valley and on highways.

Xpeng’s ambitious autonomy roadmap and internal challenge

The Silicon Valley visit also served as a benchmark for Xpeng’s own autonomy ambitions. He stated that Xpeng is looking to improve its VLA autonomous driving system to match the performance of Tesla’s FSD V14.2 within China by August 30, 2026. Xpeng is poised to release its VLA 2.0 smart driving software next quarter, though He cautioned that the initial version will not be able to match FSD V14.2’s capabilities, as noted in a CNEV Post report.

He also added a personal twist to the goal, publicly challenging Xpeng’s autonomous driving team. If the performance target is met by the 2026 deadline, the CEO stated that he will approve the creation of a Chinese-style cafeteria for Xpeng’s Silicon Valley team. If not, Liu Xianming, head of Xpeng’s autonomous driving unit, has pledged to run naked across the Golden Gate Bridge, He noted.

Another Tesla Model 3 variant in China appears to have sold out for January 2026, with the vehicle now showing an estimated delivery date of February 2026 for new orders. This bodes well for the all-electric sedan, which has maintained notable sales despite more affordable rivals like the Xiaomi SU7 and its crossover sibling, the Model Y. 

Model 3 LR RWD joins February 2026 queue

A look at Tesla China’s order page for the all-electric sedan shows that new Model 3 Long Range Rear Wheel Drive orders now have an estimated delivery date of February 2026. Priced from RMB 259,500 ($36,810), the LR RWD sits as the second-lowest-priced trim in Tesla China’s four-variant Model 3 lineup. The move follows a similar delivery timeframe for the Model 3 Performance, which remains the most expensive option for the vehicle, as noted in a CNEV Post report.

The estimated delivery dates of the two remaining Model 3 variants remain unchanged for now. The base RWD version, starting at RMB 235,500, and the LR AWD variant, priced from RMB 285,500, both continue to list estimated delivery times of 4-6 weeks. Tesla China, for its part, has continued to list in-stock Model 3 vehicles and is actively encouraging buyers to select inventory units for delivery before the end of the year.

Model Y delays and policy shifts

Delivery timelines for the Model Y in China are also stretching into 2026. All customized Model Y variants now show February 2026 as their estimated delivery date, except for the entry-level version, which still lists January 2026. Tesla has been urging customers since November to prioritize purchasing inventory vehicles, a push aimed at maximizing year-end deliveries.

Timing matters for Chinese buyers due to upcoming changes in government incentives. China’s new energy vehicle purchase tax exemption will be scaled back in 2026, which means customers who take delivery next year could face higher tax costs compared to those who are able to receive vehicles before the end of the year.

Wedbush analyst Dan Ives is doubling down on Tesla’s (NASDAQ:TSLA) long-term upside. In a post on X, the analyst stated that the electric vehicle maker could hit a $3 trillion market cap by the end of 2026 in a bullish scenario, thanks to the company’s efforts to develop and push its artificial intelligence programs. 

An aggressive valuation upside

Ives, Wedbush’s global head of tech research, stated in his post that Tesla is entering a pivotal period as its autonomy and robotics ambitions move closer to commercialization. He expects Tesla’s market cap to reach $2 trillion in 2026, representing roughly 33% upside from current levels, with a bull case up to a $3 trillion market cap by year-end.

Overall, Ives noted that 2026 could become a “monster year” for TSLA. “Heading into 2026, this marks a monster year ahead for Tesla/Musk as the autonomous and robotics chapter begins.  We believe Tesla hits a $2 trillion market cap in 2026 and in a bull case scenario $3 trillion by end of 2026… as the AI chapter takes hold at TSLA,” the analyst wrote

Ives also reiterated his “Outperform” rating on TSLA stock, as well as his $600 per share price target.

Unsupervised Full-Self Driving tests

Fueling optimism is Tesla’s recent autonomous vehicle testing in Austin, Texas. Over the weekend, at least two Tesla Model Ys were spotted driving on public roads without a safety monitor or any other occupants. CEO Elon Musk later confirmed the footage of one of the vehicles on X, writing in a post that “testing is underway with no occupant in the car.”

It remains unclear whether the vehicle was supported by chase cars or remote monitoring, and Tesla has not disclosed how many vehicles are involved. That being said, Elon Musk stated a week ago that Tesla would be removing its Safety Monitors from its vehicles “within the next three weeks.” Based on the driverless vehicles’ sightings so far, it appears that Musk’s estimate may be right on the mark, at least for now.
