The official EPA range and efficiency ratings for Tesla’s Model 3 “refresh” have been posted, and they are quite impressive. Apart from the expected range upgrades listed by Tesla in the vehicle’s online configurator, it appears that the Model 3’s efficiency has also seen some improvements.

As per data from FuelEconomy.gov, The Model 3 Long Range AWD variant really does have a range of 353 miles per charge, a significant boost from its previous 322 miles. The Model 3 Performance received a slight boost, too, from 299 miles to 315 miles of range in a single charge.

InsideEVs broke down the efficiency numbers for the “refreshed” Model 3, which was labeled in FuelEconomy.gov as the 2021 Tesla Model 3. According to the site, the Tesla Model 3 Long Range AWD’s range went up by 9.6% to 353 miles while its energy consumption decreased by about 11%, from 121 MPGe in the 2020 variant to 134 MPGe after the refresh. For additional perspective, the 2021 Model 3 LR AWD’s energy consumption is equivalent to 251 Wh/mi (156 Wh/km).

Tesla improved the range of its 2021 Model 3 Performance by 5.4% to 315 miles when compared to its 2020 counterpart fitted with 20″ Sport wheels. Unlike the Long Range AWD, the Model 3 Performance’s efficiency remained the same after the refresh at 113 MPGe or 298 Wh/mi (185 Wh/km).

The improved range of Tesla’s Model 3 refresh caught the interest of the EV community when news about its release first came out. Many people in the Tesla community wondered and speculated on the changes the company implemented to improve the Model 3’s efficiency. Among them was the addition of a heat pump to the all-electric sedan, which is used in the Model Y to optimize the vehicle’s range and efficiency in cold weather.

Tesla VP of Powertrain and Energy Engineering Drew Baglino confirmed the addition of a heat pump system in the Model 3 refresh during the recent Q3 earnings call.

“I was just going to say, I mean, I think one of the things we focused on with the Model Y and now Model 3 heat pump system was learning how to build a tightly integrated system capable of moving heat to and from anywhere really, powertrain, battery, cabin, the environment, outside ambient temperatures, all the way down to like negative 20 C, so 30 C,” Baglino said, answering a question about Tesla’s HVAC tech applied to home systems.

“I think like the heat — for heat pump in the car, being able to use the batteries both as a thermal and an electric energy reservoir is very significant,” Elon Musk elaborated.

Sandy Munro explained the significance of Tesla’s heat pump during his Model Y teardown. He noted that the heat pump system simplified the car’s climate control structure and provided Tesla a way to maximize the all-electric crossover’s efficiency. This bodes well for the vehicle’s performance in cold weather, possibly allowing the Model Y to maintain more of its estimated range even when operating in frigid temperatures.

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.
