Tesla Model Y L might never come to North America, says Elon Musk

Tesla (TSLA) CEO Elon Musk took to his social media platform X to comment on the launch of the new Model Y L midsize electric SUV in China.

According to Musk, the best chance of starting production of the new Tesla Model Y L (extra length and 6-seat interior) in the United States is at the end of next year (2026). However, he further pressed that this version of the Model Y might never come to North America.

The reason for not launching it for North America is the altered dimensions of the Model Y L. With the advent of self-driving robotaxis and Tesla Full Self-Driving (FSD), Elon Musk sees the Model Y L as unfit for this market.

With self-driving cars and robotaxis going mainstream in America, Elon Musk thinks there won’t be a need for a larger Model Y L in the US and Canada.

Musk posted on X:

This variant of the Model Y doesn’t start production in the US until the end of next year.

Might not ever, given the advent of self-driving in America.

Musk’s reason for not bringing the Model Y L to the US/North America is both surprising and revealing. The basic purpose of launching this Model Y variant is to capture the Chinese/Asian market segment that travels with 2 or 3 generations.

These extended families like to travel together, and an SUV that seats six people and still has space for some luggage satisfies their requirements. In the foreseeable future, this customer base in China and Asian countries is not going to be experiencing Tesla FSD or even need it — just the Autopilot safety features are good enough for these customers.

Interestingly, the regular Model Y Juniper is Tesla’s preferred choice for FSD (Supervised) testing. The tech & AI-based automaker is only using the new Model Y Juniper vehicles for Robotaxi service in Austin and the SF Bay Area.

In the same discussion thread, a large majority of Tesla owners, enthusiasts, and Elon Musk fans disagree with the company’s CEO. Potential Tesla customers with three kids or a group of friends travelling together would prefer a 6-seat configuration.

A 6-seat Model Y makes more sense because of its affordability, as the Model X SUV is way too expensive for the common American family.

The sales of the luxury segment Model S and Model X have declined significantly in the last few quarters. Tesla Model Y L can be a good replacement for the Model X for a customer base that’s not willing to pay upwards of $100K for a family car.

Tesla has ample time to decide whether to launch the new Model Y L in the US and Canada. If the data suggests that there is a sizable market in North America, Elon Musk might change his mind and decide to start production at a US factory.

Moon Five receives .4 million grant to deploy over 450 EV chargers in California apartments

Moon Five Technologies has announced plans to install more than 450 EV charging units at multifamily properties in Los Angeles and San Francisco, following a $3.4 million grant from the California Energy Commission under the REACH 3.0 program. This initiative is focused on providing EV charging access to underserved communities, particularly renters in disadvantaged areas, and will be supported by partnerships with local nonprofit housing providers.

Moon Five Technologies’ plug-and-play units connect directly downstream of a tenant’s existing electric meter and monitor available power, allowing tenants to charge EVs without requiring utility-driven infrastructure upgrades. This model bypasses the need for building-wide electrical upgrades or landlord involvement, with installation times claimed to be as short as two weeks from initial coordination through permitting and final installation.

The company’s solution uses a proprietary energy management system and bidirectional-ready charger. By creating a dedicated circuit downstream of each tenant’s meter, Moon Five enables apartment-level load balancing to avoid overloads and optimize energy use. Technical features include capacity for load shedding and bidirectional energy resiliency, which are intended to support eventual grid integration and offer tenants more control over energy usage.

The deployment will prioritize buildings and neighborhoods most impacted by limited infrastructure investment, air pollution and climate vulnerability, as listed by the California Energy Commission’s REACH 3.0 program requirements.

“EV charging has never really been built for renters until now,” said Stephan Ng, CEO of Moon Five Technologies. “Our unique model puts renters first, making it possible to install reliable, affordable charging without costly upgrades or utility delays. This grant allows us to bring that vision to life in communities that have historically been excluded from clean transportation infrastructure, while delivering on our mission to make equitable, resilient EV charging a reality for every renter.”

Installations are scheduled to begin in early 2026.

Toshiba launches 650 V SiC MOSFETs in TOLL packages for EV charging and power electronics

Toshiba Electronic Devices & Storage Corporation has introduced three 650 V silicon carbide (SiC) metal–oxide–semiconductor field-effect transistors (MOSFETs) that use its third-generation SiC technology in surface-mount TOLL packages. These new devices, part numbers TW027U65C, TW048U65C, and TW083U65C, are designed for industrial power electronics with initial volume shipments beginning August 2025.

The company reports that these third-generation SiC MOSFETs are housed in general-purpose TOLL surface-mount packages, which reduce device volume by more than 80 percent compared to through-hole packages such as TO-247 and TO-247-4L(X). This enables increased equipment power density and supports automated manufacturing.

Toshiba says the TOLL package offers lower parasitic impedance—resistance and inductance—than through-hole packages, resulting in decreased switching losses. As a four-terminal package, TOLL allows for a Kelvin connection signal source, which minimizes the impact of source wire inductance on gate driving performance. This design leads to higher switching speeds; for example, the TW048U65C reportedly achieves approximately 55 percent lower turn-on loss and 25 percent lower turn-off loss compared to previous Toshiba 650 V SiC MOSFETs in a TO-247 package without Kelvin connection.

The new MOSFET lineup features optimized drift and channel resistance ratios for improved temperature dependence of drain-source on-resistance. Additional technical specifications include low drain-source on-resistance times gate-drain charge and a typical diode forward voltage (VDSF) of -1.35 V at VGS = -5 V.

While suitable for various industrial power electronics, Toshiba identifies EV charging stations and photovoltaic inverters as specific target applications. The devices are also intended for switched-mode power supplies in data centers, servers, communications equipment, and uninterruptible power supplies.

Tesla’s Master Plan Part 4: Big Vision, Bigger Questions

When Elon Musk drops a new “Master Plan,” Tesla fans tend to pay attention. The first plan back in 2006 was simple: build a sports car, use the profits to make more affordable cars, and eventually move into clean energy. That roadmap gave us the Roadster, Model S, Model 3, and the solar and energy business Tesla runs today.

Fast-forward almost two decades, and Master Plan Part 4 is here. This one is different. Instead of a roadmap built on cars, batteries, and charging networks, the focus is on artificial intelligence and robotics. Tesla calls it the path to “sustainable abundance.”

So what does that actually mean? At its core, Tesla is saying it wants to build technology that solves problems at scale. The company believes that AI, combined with its manufacturing power, can unlock new levels of efficiency, safety, and convenience.

“We are unifying our hardware and software at scale, and in doing so, we are creating a safer, cleaner and more enjoyable world,” the plan states.

Tesla lays out a few guiding principles. Growth, it argues, doesn’t have to mean trade-offs. Shortages can be solved with innovation, much like Tesla pushed batteries from niche tech into mainstream automotive use. The plan also leans heavily on the idea that autonomy and robotics, especially Tesla’s humanoid robot, Optimus could take on dangerous or repetitive jobs, freeing up time for people to focus on what matters most to them.

There’s also a push for accessibility. Tesla insists that advanced products need to be affordable and widely available to drive real change. That’s a theme we’ve seen before, the company moved from a high-end Roadster to mass-market cars like the Model 3 and Model Y. Master Plan 4 suggests that same philosophy could apply to future AI and robotics products.

For Tesla drivers today, the plan doesn’t set new car targets or immediate EV milestones. Instead, it positions the company as more than an automaker. Tesla wants to be seen as a builder of tools that could shape everything from mobility to energy to labor itself. That’s a big shift, and while some of it may sound far-off, Tesla has a track record of turning ambitious visions into real products, sometimes late, sometimes imperfect, but often industry-changing.

The takeaway? Master Plan 4 won’t affect your daily drive in a Model Y or your next charging stop at a Supercharger. But it does show where Tesla sees itself heading in the long run: toward a world where AI and robotics are as central to the brand as electric vehicles.

Kempower, a Finnish manufacturer of DC fast charging systems, has approved Formula Space’s CableGuard anti-theft solution for use with its EV charging stations after conducting eight weeks of in-house testing. According to Kempower, it is the first to validate a third-party solution that uses DNA traceability to deter cable theft.

CableGuard includes a cut-resistant sleeve that does not require steel reinforcement, aiming to minimize impact on end-user experience and charger operation. A core feature is its forensic traceability: if a protected cable is tampered with, the system releases a transparent, high-pressure fluid embedding a unique DNA code specific to the charging site. The coding, visible only under ultraviolet light, is linked to a police-accessible database, allowing for site-specific identification of offenders—an approach Formula Space says is unique within the industry.

Kempower says that supported cable configurations include CCS2 cables up to 300 A and five-meter length, and CHAdeMO cables up to five-meter length. The approval covers applications in the UK, Ireland and continental Europe. CableGuard must be applied by Kempower Certified Service Partners in line with its application guidance.

Australian mining firm International Graphite has partnered with Arctic Graphite, a subsidiary of Norwegian construction giant Leonhard Nilsen & Sonner (LNS), and Graphite Investment Partners (GIP) to establish a new expandable graphite production facility in Germany.

The new plant is scheduled to start operations in 2027, and is expected to produce around 3,000 tons annually. Expandable graphite is used as a flame retardant in construction materials and insulation in electronics, as well as in batteries and green steel electrodes.

GIP has committed to arranging funding for at least 50% of the estimated €5-million ($5.86-million) capital cost of the facility, and has issued a non-binding letter of interest to arrange up to $10 million in total funding.

International Graphite and Arctic Graphite plan to form a 50/50 joint venture to finance, build and operate the plant.

The plant will be International Graphite’s second processing facility. The company has been piloting downstream graphite processing in Australia for the past six years and is currently building a commercial graphite micronizing plant in Collie, Western Australia.

The company aims to establish an international network of processing facilities that will produce a range of graphite products, from micronized and expandable to advanced battery anode material, using natural graphite from a mine at the company’s Springdale graphite resource, which is also in Western Australia.

“Graphite is subject to supply disruption more than any other commodity. The demand fundamentals for expandable graphite are compelling. There is little or no production of this product in the EU, which accounts for approximately 30 per cent of global consumption outside of China,” said Aidan Nania, Principal at Graphite Investment Partners.

Eaton has announced that its Mobility Group will supply its High-Power Lock Box (HPLB) SQ8 connector system to a major global OEM for a new PHEV platform. This agreement is the first application of the SQ8 variant in a PHEV.

The SQ8 configuration of the HPLB connector features a patented, inverted terminal contact design that combines a stainless-steel spring to maintain consistent contact force—especially after repeated thermal cycling—with a copper current carrier to maximize conductivity. Eaton says this design addresses common failure modes like mechanical relaxation found in high-vibration electric vehicle environments.

The HPLB SQ8 terminal has been internally tested and benchmarked against publicly available competitor data, reportedly delivering a 25 to 35 percent improvement in current-carrying capability for a given wire size, and 30 to 60 percent higher current per unit volume, which can support lighter and more efficient vehicle platforms.

The HPLB SQ8 connector is designed for demanding applications such as battery disconnect units (BDUs), high-voltage heaters and propulsion systems in EVs, PHEVs and heavy-duty commercial vehicles. The system supports up to 270 amps of current with minimal resistance loss and operates at temperatures up to 125 degrees Celsius. It offers a tool-free push-click-pull mating process that requires only 70 newtons of force, intended to reduce operator fatigue and eliminate the need for mechanical levers.

Technical highlights include a two-piece terminal compatible with 25 to 70 mm² wire gauges, flexible 90-degree and 180-degree terminal orientations for demanding packaging constraints, eight spring-loaded contact points, and compliance with USCAR-2 T3/V2/S3 and ISO standards. The connector is finger-proof, validated for up to 10 mating cycles, and features QR code-enabled part traceability for logistics and quality control.

Eaton notes that its HPLB family of connectors, including the previously released SQ4 variant, has already been deployed in commercial truck platforms, select electric vehicle applications, and high-current heating systems.
