Published

on

Tesla recently shared a short video clip of the silver Semi stealthily gliding over the Golden Gate Bridge while hauling a trailer on the way to Santa Rosa, CA.

The video clip of the silver Semi, with trailer in tow, was shared on Twitter, where it caused quite a conversation among Tesla’s followers on the platform. Some remarked that the vehicle was unearthly in its silence despite seemingly traveling at near-highway speed. Others jested that the way the Semi glided over the Golden Gate Bridge almost made the vehicle look like a computer-generated image, prompting a lighthearted response from Tesla’s Twitter account assuring that the footage was indeed real

In a follow-up clip featuring the electric truck heading to the Golden Gate Bridge, the logo of Xtra Lease Trailers was visible on the Semi’s cargo, suggesting that Tesla could be a client of the leasing company. Xtra Lease Trailers, a Berkshire Hathaway Company based on St. Louis, MO, is among the United States’ most prolific trailer lease providers, with a fleet of 85,000 trailers to date. 

A Tesla fan has also shared an image of the Semi on Twitter just as it was about to enter the Golden Gate Bridge. Just like in recent sightings, such as the one near the LA Service Center — a place that holds historical significance to the company.

While the Elon Musk-led company did not specify the purpose of the Semi’s trip to Santa Rosa on its Twitter video, Tesla’s VP of Truck Programs Jerome Guillen noted in his LinkedIn profile that the footage was taken last week, and that the trip was conducted to visit “some great local customers.”

Guillen and the team currently testing the Tesla Semi have been spotted in several areas of the United States, especially in the route between the company’s Fremont, CA factory and the Sparks, NV Gigafactory. As stated by Elon Musk earlier this year, Tesla is now using the two electric trucks as part of its fleet tasked with transporting Model 3 battery packs from Gigafactory 1 to Fremont. The two massive electric vehicles have also been spotted in the route between Tesla’s headquarters in Palo Alto, CA and the Fremont.

The Tesla Semi has been well-received by several prolific transport and trucking companies, both in the United States and abroad. During the company’s Q1 2018 earnings call, Tesla CEO Elon Musk and CTO JB Straubel noted that there are roughly 2,000 reservations for the electric long-hauler to date. So far, companies that have publicly announced their orders for the vehicle include companies such as PepsiCo, FedEx, and UPS in the United States and Bee’ah from the United Arab Emirates.

Over the past few months, the Tesla Semi has also been spotted visiting the site of several key reservation holders, such as Anheuser-Busch in St. Louis, MO. The electric truck was also demoed for PepsiCo employees in Dallas, TX. The black Tesla Semi, speculated to be the short-range variant of the vehicle, was also spotted being transported at a highway near Des Moines, IA, close to the headquarters of Ruan Transportation Management Systems, another one of the Semi’s reservation holders.

Some companies with reservations for the Tesla Semi are currently working with Tesla to set up a charging network for the massive long-haulers. Dubbed as the Megachargers, the Tesla Semi charging stations will be installed at key locations that are frequently traveled by fleet operators. This would enable truck drivers to travel between facilities without having to recharge each time they load and unload cargo.

Tesla has confirmed that the larger six-seat Model Y L will launch in Australia and New Zealand in 2026. 

The confirmation was shared by techAU through a media release from Tesla Australia and New Zealand.

The Model Y L expands the Model Y lineup by offering additional seating capacity for customers seeking a larger electric SUV. Compared with the standard five-seat Model Y, the Model Y L features a longer body and extended wheelbase to accommodate an additional row of seating.

The Model Y L is already being produced at Tesla’s Gigafactory Shanghai for the Chinese market, though the vehicle will be manufactured in right-hand-drive configuration for markets such as Australia and New Zealand.

Tesla Australia and New Zealand confirmed the vehicle will feature seating for six passengers.

“As shown in pictures from its launch in China, Model Y L will have a new seating configuration providing room for 6 occupants,” Tesla Australia and New Zealand said in comments shared with techAU.

Instead of a traditional seven-seat arrangement, the Model Y L uses a 2-2-2 layout. The middle row features two individual seats, allowing easier access to the third row while providing additional space for passengers.

Tesla Australia and New Zealand also confirmed that the Model Y L will be covered by the company’s updated warranty structure beginning in 2026.

“As with all new Tesla Vehicles from the start of 2026, the Model Y L will come with a 5-year unlimited km vehicle warranty and 8 years for the battery,” the company said.

The updated policy increases Tesla’s vehicle warranty from the previous four-year or 80,000-kilometer coverage.

Battery and drive unit warranties remain unchanged depending on the variant. Rear-wheel-drive models carry an eight-year or 160,000-kilometer warranty, while Long Range and Performance variants are covered for eight years or 192,000 kilometers.

Tesla has not yet announced official pricing or range figures for the Model Y L in Australia.

Tesla Roadster patent hints at radical seat redesign ahead of reveal

Published

on

By

A newly published Tesla patent could offer one of the clearest signals yet that the long-awaited next-generation Roadster is nearly ready for its public debut.

Patent No. US 20260061898 A1, published on March 5, 2026, describes a “vehicle seat system” built around a single continuous composite frame – a dramatic departure from the dozens of metal brackets, recliner mechanisms, and rivets that make up a traditional car seat. Tesla is calling it a monolithic structure, with the seat portion, backrest, headrest, and bolsters all thermoformed as one unified piece.

The approach mirrors Tesla’s broader manufacturing philosophy. The same company that pioneered massive aluminum castings to eliminate hundreds of body components is now applying that logic to the cabin. Fewer parts means fewer potential failure points, less weight, and a cleaner assembly process overall.

Tesla ramps hiring for Roadster as latest unveiling approaches

The timing of the filing is difficult to ignore. Elon Musk has publicly targeted April 1, 2026 as the date for an “unforgettable” Roadster design reveal, and two new Roadster trademarks were filed just last month. A patent describing a seat architecture suited for a hypercar, and one that Tesla has promised will hit 60 mph in under two seconds.

The Roadster, originally unveiled in 2017, has been one of Tesla’s most anticipated yet most delayed products. With a target price around $200,000 and engineering ambitions to match, it is being positioned as the ultimate showcase for what Tesla’s technology can do.

Tesla Roadster Monolithic Seat: Feature Highlights via US Patent 20260061898 A1

  1. Single Continuous Frame (Monolithic Construction). The core invention is a seat assembly built from one continuous frame that integrates the seat portion, backrest portion, and hinge into a single component — eliminating the need for separate structural parts and mechanical joints typical in conventional seats.
  2. Integrated Flexible Hinge. Rather than a traditional mechanical recliner, the hinge is built directly into the continuous frame and is designed to flex, and allowing the backrest to move relative to the seat portion. The hinge can be implemented as a fiber composite leaf spring or an assembly of rigid linkages.
  3. Thermoformed Anisotropic Composite Material. The continuous frame is manufactured via thermoforming from anisotropic composite materials, including fiberglass-nylon, fiberglass-polymer, nylon carbon composite, Kevlar-nylon, or Kevlar-polymer composites, enabling a molded-to-shape monolithic structure.
  4. Regionally Tuned Stiffness Zones. The frame is engineered with up to six distinct stiffness regions (R1–R6) across the seat, backrest, hinge, headrest, and bolsters. Each zone can have a different stiffness, allowing precise ergonomic and structural tuning without adding separate components.
  5. Linkage Assembly Hinge Mechanism. The hinge incorporates one or more linkage assemblies consisting of multiple interlocking links with gears, connected by rods. When driven by motors or actuators, these linkages act as a flexible member to control backrest movement along a precise, ergonomically optimized trajectory.
  6. Multi-Actuator Six-Degree-of-Freedom Positioning System. The seat uses four distinct actuator pairs, all controlled by a central controller. These actuators work in coordinated combinations to achieve fore/aft, height, cushion tilt, and backrest rotation adjustments simultaneously.
  7. ECU-Based Controller Architecture. An Electronic Control Unit (ECU) and programmable controller manage all seat actuators, receive user input via a user interface (touchscreen, buttons, or switches), and incorporate sensor feedback to confirm and maintain desired seat positions, essentially making this a software-driven seat system.
  8. Airbag-Integrated Bolster Deployment System. The backrest bolsters (216) are geometrically shaped and sized to guide airbag deployment along a specific, pre-configured trajectory. Left and right bolsters can have different shapes so that each guides its respective airbag along a distinct trajectory, improving occupant protection.
  9. Ventilation Holes Formed into the Backrest. The continuous frame includes one or more ventilation holes formed directly into the backrest portion, configured to either receive airflow into or deliver airflow from the seat frame — enabling passive or active thermal comfort without requiring separate ventilation components.
  10. Soft Trim Recess for Tool-Free Integration. The headrest and backrest portions together define a molded recess, specifically designed to receive and secure a soft trim component (foam, fabric, or cushioning) directly into the continuous frame, eliminating the need for separate attachment hardware and simplifying final assembly.

Elon Musk’s artificial intelligence company xAI has filed a permit to construct a new building at its growing data center complex outside Memphis, Tennessee. 

As per a report from Data Center Dynamics, xAI plans to spend about $659 million on a new facility adjacent to its Colossus 2 data center. Permit documents submitted to the Memphis and Shelby County Division of Planning and Development show the proposed structure would be a four-story building totaling about 312,000 square feet.

The new building is planned for a 79-acre parcel located at 5414 Tulane Road, next to xAI’s Colossus 2 data center site. Permit filings indicate the structure would reach roughly 75 feet high, though the specific function of the building has not been disclosed.

The filing was first reported by the Memphis Business Journal.

xAI uses its Memphis data centers to power Grok, the company’s flagship large language model. The company entered the Memphis area in 2024, launching its Colossus supercomputer in a repurposed Electrolux factory located in the Boxtown district.

The company later acquired land for the Colossus 2 data center in March last year. That facility came online in January.

A third data center is also planned for the cluster across the Tennessee–Mississippi border. Musk has stated that the broader campus could eventually provide access to about 2 gigawatts of compute power.

The Memphis cluster is also tied to new power infrastructure commitments announced by SpaceX President Gwynne Shotwell. During a White House event with United States President Donald Trump, Shotwell stated that xAI would develop 1.2 gigawatts of power for its supercomputer facility as part of the administration’s “Ratepayer Protection Pledge.”

“As you know, xAI builds huge supercomputers and data centers and we build them fast. Currently, we’re building one on the Tennessee-Mississippi state line… xAI will therefore commit to develop 1.2 GW of power as our supercomputer’s primary power source. That will be for every additional data center as well… 

“The installation will provide enough backup power to power the city of Memphis, and more than sufficient energy to power the town of Southaven, Mississippi where the data center resides. We will build new substations and invest in electrical infrastructure to provide stability to the area’s grid,” Shotwell said.

Shotwell also stated that xAI plans to support the region’s water supply through new infrastructure tied to the project. “We will build state-of-the-art water recycling plants that will protect approximately 4.7 billion gallons of water from the Memphis aquifer each year. And we will employ thousands of American workers from around the city of Memphis on both sides of the TN-MS border,” she said.
