Tesla: EPA’s proposal does not go far enough in electrifying heavy-duty vehicles

Tesla is urging the Biden administration to adopt stricter heavy-duty emission limits than those that were proposed by the Environmental Protection Agency (EPA) back in April. While the EPA’s proposal outlined a path towards the electrification of the US’ heavy-duty transportation sector, Tesla has argued that the agency’s suggestions do not go far enough. 

Tesla reportedly noted that the emission limits for heavy-duty trucks should be as stringent as the truck emissions regulations of California. The EV maker also called for the elimination of credits that would make it easier for truckmakers to comply with emissions regulations. Without tighter standards, the company stated that the rule would “not meet the legal benchmark of the Clean Air Act to protect the nation’s public health and welfare.”

As per the EPA’s proposal, 50% of new vocational vehicles, such as garbage trucks and buses, could be EVs by 2032. The proposal also suggested that 35% of new short-haul freight tractors and 25% of new long-haul freight tractors could be electric at the same time timeframe. Medium-duty vehicle rules are also expected to cut emissions by 44% over 2026 requirements, as noted in a Reuters report.

As part of its comments, Tesla pointed to its own Class 8 all-electric truck, the Semi, which started customer deliveries last December. The Semi is only being produced in small numbers today, but its real-world performance seems promising. Tesla noted that it is expected to hit a production rate of about 50,000 Semis per year. Significant volumes of the all-electric truck are also expected starting around late 2024, the EV maker stated.

Tesla also reportedly submitted the Semi’s production plans through 2030 to the EPA. The plans, however, were not made public. “Reaching the 50,000 annual production level would amount to 20% of all annual sales in (model year) 2027. This means Tesla’s production goal alone would far exceed the 5% EV sales deployment EPA anticipates in 2027,” Tesla wrote.

Tesla’s stance is understandable considering the presence of the Semi in its lineup of vehicles. Tesla is also the undisputed leader in EVs in the United States, so an aggressive shift towards electric mobility in the heavy-duty sector would be beneficial for the company. Interestingly enough, industry group American Trucking Associations has adopted the complete opposite stance as Tesla. The group argued that the EPA’s proposal is simply too aggressive, and it also “relies on technology that is at early-stage and lacks the real-world demonstrated maturity compared to proven internal combustion engine vehicle (ICEV) technologies.”

Tesla makes latest move to remove Model S and Model X from its lineup

Tesla’s latest decisive step toward phasing out its flagship sedan and SUV was quietly removing the Model S and Model X from its U.S. referral program earlier this week.

Tesla has made its latest move that indicates the Model S and Model X are being removed from the company’s lineup, an action that was confirmed by the company earlier this quarter, that the two flagship vehicles would no longer be produced.

Tesla has ultimately started phasing out the Model S and Model X in several ways, as it recently indicated it had sold out of a paint color for the two vehicles.

Now, the company is making even more moves that show its plans for the two vehicles are being eliminated slowly but surely.

Tesla’s latest decisive step toward phasing out its flagship sedan and SUV was quietly removing the Model S and Model X from its U.S. referral program earlier this week.

The change eliminates the $1,000 referral discount previously available to new buyers of these vehicles. Existing Tesla owners purchasing a new Model S or Model X will now only receive a halved loyalty discount of $500, down from $1,000.

The updates extend beyond the two flagship vehicles. New Cybertruck buyers using a referral code on Premium AWD or Cyberbeast configurations will no longer get $1,000 off. Instead, both referrer and buyer receive three months of Full Self-Driving (Supervised).

The loyalty discount for Cybertruck purchases, excluding the new Dual Motor AWD trim level, has also been cut to $500.

These adjustments apply only in the United States, and reflect Tesla’s broader strategy to optimize margins while boosting adoption of its autonomous driving software.

The timing is no coincidence. Tesla confirmed earlier this year that Model S and Model X production will end in the second quarter of 2026, roughly June, as the company reallocates factory capacity toward its Optimus humanoid robot and next-generation vehicles.

With annual sales of the low-volume flagships already declining (just 53,900 units in 2025), incentives are no longer needed to drive demand. Production is winding down, and Tesla expects strong remaining interest without subsidies.

Industry observers see this as the clearest sign yet of an “end-of-life” phase for the vehicles that once defined Tesla’s luxury segment. Community reactions on X range from nostalgia, “Rest in power S and X”, to frustration among long-time owners who feel perks are eroding just as the models approach discontinuation.

Some buyers are rushing orders to lock in final discounts before they vanish entirely.

For Tesla, the move prioritizes efficiency: fewer discounts on outgoing models, a stronger push for FSD subscriptions, and a focus on high-margin Cybertruck trims amid surging orders.

Loyalists still have a narrow window to purchase a refreshed Plaid or Long Range model with remaining incentives, but the message is clear: Tesla’s lineup is evolving, and the era of the original flagships is drawing to a close.

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.
