Tesla continues rapid innovation with new seat patent
In February of 2019, Tesla filed a patent for a “Vehicle seat with an integrated temperature-control system,” and now it seems the company has just updated the patent.
The new system will heat or cool the seats as needed with the use of coolant, which will ultimately lead to increased comfort and reduced power usage.
The new system will be much more efficient and comfortable than current heated seat technology. Traditionally, car seats get heated by an electric current that flows through resistors and get cooled by a fan under the seat.
The difference between electric resistor-based seat heaters and these new refrigerant-based seats could be compared to Tesla vehicles with electric heaters and those with a heat pump.
A model with a heat pump extracts heat from a refrigerant that is run through the system instead of generating heat using electricity directly. Heat pumps are much more efficient at generating heat when compared to electric heaters. We’d expect a similar efficiency gain from Tesla switching to these new temperature controlled seat heaters.
Most seat heating and cooling systems have 3 heat/cool settings that must be manually adjusted. These types of seat heaters are basically on/off switches and can not control the temperature of the seat well.
Tesla recently added automatic seat heater functionality to Teslas to help address this issue. The new auto setting will automatically turn on seat heaters then gradually lower their temperature as the cabin warms. However, it appears that Tesla is aiming to provide an even better solution with this patent.
Precise Temperature Control
These new seats would be able to precisely control their temperature so that you can set an exact temperature for your seat just like you do for the cabin temperature.
The new seats would be much more efficient than using electric seat heaters and would provide better cooling than running cold air through vented seats.
Better Cooled Seats
Ventilating air through the seat is rarely enough to remove excess heat for the comfort of the passenger.
Instead of blowing cold air into the seat, these new seats would work like an air conditioning system, by removing heat from the seat. This would be much more effective at cooling down the passenger.
Additionally, traditional seat heating systems take up a lot of space and are ineffective because heat typically has to travel through multiple layers of fabric and other materials.
The same way fluid is used to heat/cool batteries, the new system will more effectively transfer heat with the circulation of fluid in between layers of the seats.
The new patent includes multiple layers inside the seat. Under the outermost layer of the seat, there will be a layer of heating/cooling fluid. The fluid will circulate under this layer through the entire seat to ensure that all parts are evenly heated/cooled.
This invention shows how Tesla is innovating and paying great attention to detail in every possible way to make their vehicles more efficient, comfortable and enjoyable for the user.

There has been extensive reporting on what the long-anticipated affordable EV option would become, and we’ve seen numerous news stories mentioning that it was delayed or even arriving on time. The executive team revealed the near-term and long-term plans for Tesla’s upcoming vehicles, and there’s definitely good news to share here.
Updated Timeline
The most important piece of news is that despite all the talk of delays from supposed inside sources, Tesla has confirmed that the plan for its more affordable model remains on schedule for production to begin in the first half of 2025. Tesla’s executive team narrowed that timeline down further - and said that they expect production to kick off as soon as June and that the new model will be in the market shortly thereafter.
While the production timeline itself is on track, Tesla did note that the subsequent ramping process will likely be slower than initially hoped, citing global tariff and financial impacts as challenges to overcome to prepare its production lines.
Hybrid Production Approach
Tesla has once again confirmed that this will not be their next-generation vehicle, built using new production methods. Instead, they outlined a relatively more pragmatic approach for this new model.
Tesla will utilize aspects of both the next-generation platform as well as some parts of its current platforms (namely the Model 3 and Model Y). This means that Tesla will produce this new vehicle on the same manufacturing lines as the Model 3 and Model Y.
This strategy allows Tesla to bring the vehicle to the market more quickly, while also managing capital expenditures more efficiently by using existing infrastructure. However, Tesla’s executive team also noted that this approach, while faster, will result in fewer cost reductions than what might have been achieved with an entirely new platform and dedicated manufacturing process.
Vehicle Design
Using these existing production lines means that Tesla’s new vehicle will likely share some considerable similarities with either the existing Model 3 or Model Y. Rather than being a radically different and smaller vehicle, this new model will resemble the overall form factor and shape of Tesla’s current core offerings, while being optimized for a lower cost.
This doesn’t mean that Tesla is forgetting the overall goal here. Their ultimate goal is to reduce the initial cost of ownership and lower monthly payments for customers while maintaining a standard of excellence and safety.
Not Unboxed
Both at this Earnings Call and previous ones, Tesla has indicated that this new vehicle will not be using the innovative unboxed assembly method, at least for the time being. That relatively unique method will be developed and implemented specifically for the purpose-built Cybercab and for future vehicles on the next-generation platform.
We’re just a few days away from May, so it won’t be long before we see more about this upcoming vehicle. Stay tuned.
In a follow-up move to the current US administration’s goals to introduce a federal framework for autonomous vehicles, the US Department of Transportation (USDOT) is loosening autonomy restrictions following an announcement from Secretary Sean Duffy on X. This new initiative helps streamline complex regulatory processes and foster home-grown innovation.
From the Wright Brothers to the first astronauts on the moon, our nation has always been at the forefront of transportation technology.
That’s why today we're unveiling a new Automated Vehicle Framework from @USDOT’s Innovation Agenda ⬇️ ⬇️ pic.twitter.com/W3kbMUwQSn
As part of the broader upcoming USDOT Innovation Agenda, the newly unveiled AV Framework is designed to promote American innovation and strengthen domestic engineering while maintaining existing safety standards. The framework centers around three key principles:
Prioritize Safety
Unleash Innovation
Enable Commercial Deployment
To kickstart this AV framework, USDOT announced two initial steps focused on streamlining processes and expanding opportunities.
Crash Reporting Requirements
Under the first principle to Prioritize Safety, the National Highway Traffic and Safety Administration (NHTSA) will maintain its Standing General Order requiring crash reporting on Advanced and Automated Driver Assistance Systems (ADAS and ADS).
However, the reporting process will be streamlined following feedback from AV innovators, likely including Tesla. The goal here is to focus on collecting critical safety information while removing unnecessary or duplicative items from the reporting process, thereby reducing the burden without compromising safety.
Cutting Red Tape
Directly tied to the second principle of Unleash Innovation, the framework also seeks to slash red tape. The first step here is the expansion of the Automated Vehicle Exemption Program, or AVEP. This program allows manufacturers to petition for temporary exemptions from certain federal motor vehicle safety standards (FMVSS) for testing or deployment purposes.
Previously, the standard excluded domestically produced vehicles. Now, domestically produced AVs will not need to meet FMVSS, which will broaden the scope for manufacturers to test more innovative and unique designs and technologies.
Single National Standard for AVs
Finally, tied to the third principle of Enable Commerical Development, USDOT intends to move the United States closer to a single national standard for autonomous vehicles. This aims to prevent a confusing and inefficient patchwork of state-level or city-level laws and regulations, which can create hurdles for companies attempting to innovate, deploy, and scale their technology.
A unified standard across the United States also means that Canada and Mexico will likely be able to follow, as they share homologization standards across North America, including for vehicle crash safety and some autonomy regulations.
What This Means for Tesla
These framework changes will likely have a substantial impact on Tesla. The move towards a national standard is potentially the most impactful change, as Tesla identified regulatory hurdles as one of the most significant challenges it will face with the deployment of both Unsupervised FSD and its Robotaxi network.
The reduction of FMVSS requirements and streamlined reporting will likely play a role in the future as well. The FMVSS requirements are probably already being worked on, if not already met, by the Cybercab and other vehicles in Tesla’s lineup.
Meanwhile, the streamlined reporting will be helpful once Tesla officially launches its Robotaxi network in June.
