Update: Pre-2024 Model 3 trunk specs added on 9/16/23.
The Tesla Model 3 Highland has been making headlines in the past several weeks, as many have been able to take their first looks at the refreshed vehicle. Ahead of initial deliveries, some specifications for the refreshed Model 3 have surfaced — most recently including measurements for the frunk and trunk.
X user @DerCaspar shared photos of the Model 3 Highland on display at the Mall of Berlin on Friday, along with measurements for the newly redesigned vehicle’s frunk and trunk. Additionally, Caspar shared details about the sub-trunk, the small space beneath the floor of the trunk.
Check out the trunk, sub-trunk and frunk measurements below, according to Caspar:
Tesla Model 3 Highland trunk
– back row up 107 cm (~42.1 inches)
– back row down till seat 187 cm (~73.6 inches)
– back row down till seat moved 210 cm (~82.7 inches)
– back row down till front screen 270 cm (~106.3 inches)
– width between wheel covers 94 cm (~37 inches)
– width between back row hand bars 129.5 cm (~51 inches)
– height trunk opening 46 cm (~18.1 inches)
Tesla Model 3 Highland sub-trunk
– height till sub-trunk cover 29 cm (~11.4 inches)
– narrowest width 63 cm (~24.8 inches)
– narrowest depth 32 cm (~12.6 inches)
Tesla Model 3 Highland frunk
– frunk height 23 cm (~9.1 inches)
– frunk width 72 cm (~28.3 inches)
– frunk depth 35 cm (~13.8 inches)
You can see Caspar’s full thread on X below, where he details his initial impressions of the Model 3 Highland.

Caspar also updated the thread with a German forum showing the pre-Highland Model 3’s trunk, sub-trunk and frunk dimensions. It’s worth noting that the measurements aren’t all taken the exact same way. As one example, Caspar measured the sub-trunk width and depth at its narrowest points, while the forum user measured the old Model 3’s depth at its deepest point.
Still, comparing the two sets of dimensions can provide a pretty good comparison point for the refreshed Highland Model 3.
You can head to the forum to see pictures showing how each dimension was measured.
Pre-2024 Tesla Model 3 (non-Highland) trunk
– back row up 107 cm (~42.1 inches)
– back row down till seat 190 cm (~74.8 inches)
– back row down till seat moved completely forward 206 cm (~81.1 inches)
– width between wheel covers 94 cm (~37 inches)
– height trunk opening 46 cm (~18.1 inches)
Pre-2024 Tesla Model 3 (non-Highland) sub-trunk
– height 30 cm (~11.8 inches)
– deepest depth 46 cm (~18.1 inches)
– width 61 cm (~24 inches)
Pre-2024 Tesla Model 3 (non-Highland) frunk
– frunk height 20 cm (~7.9 inches)
– frunk depth 38 cm (~15 inches)
– frunk width at 71 cm (~28 inches)
Other features in the Tesla Model 3 Highland
In addition to providing measurements for the trunk, sub-trunk and frunk spaces, Caspar later noted a few of his favorite features in the Model 3 Highland. These included the infotainment screen in the back row, the updated headlights and general Model S-like exterior appearance, and the car’s upgraded sound dampening.
He also notes the ability to control climate and seat heating separately for the right and left rear passengers and the customizable ambient lighting strip across the front interior of the car as impressive updates. Later in the thread, a few users also pointed out that the rear fog lights flash when the trunk is opened, which is another new feature for the refreshed Model 3. When asked if he was able to try the new ventilated seats, Caspar said he hasn’t, though he plans to.
In recent weeks, users have also pointed out the Model 3 Highland’s new features, such as Auto-Shift out of Park, updated airbag placement, a blindspot indicator and several other upgrades. Earlier this week, the Model 3 Highland’s size was also revealed after the vehicle was officially registered with the China Ministry of Industry and Information Technology.

Tesla VP explains latest updates in trade secret theft case
Tesla reportedly caught Matthews copying the tech into machines that were sold to competitors, claiming they lied about doing so for three years, and continued to ship it. That is when Tesla chose to sue Matthews in July 2024 in Federal court, demanding over $1 billion in damages due to trade secret theft.
Tesla Vice President Bonne Eggleston explained the latest updates in a trade secret theft case the company has against a former manufacturing equipment supplier, Matthews International.
Back in 2024, Tesla had filed a lawsuit against Matthews International, alleging that the firm stole trade secrets about battery manufacturing and shared those details with some of Tesla’s competitors.
Early last year, a U.S. District Court Judge denied Tesla’s request to block Matthews International from selling its dry battery electrode (DBE) technology across the world. The judge, Edward Davila, said that the patent for the tech was due to Matthews’ “extensive research and development.”
The two companies’ relationship began back in 2019, as Tesla hired Matthews to help build the equipment for its 4680 battery cell. Tesla shared confidential software, designs, and know-how under strict secrecy rules.
Fast forward a few years, and Tesla reportedly caught Matthews copying the tech into machines that were sold to competitors, claiming they lied about doing so for three years, and continued to ship it. That is when Tesla chose to sue Matthews in July 2024 in Federal court, demanding over $1 billion in damages due to trade secret theft.
Now, the latest twist, as this month, a Judge issued a permanent injunction—a court order banning Matthews from using certain stolen Tesla parts or designs in their machines. Matthews is also officially “liable” for damages. The exact amount would still to be calculated later.
Bonne Eggleston, a VP for Tesla, said on X today that Matthews is a supplier who “exploited customer IP through theft or deception,” and has no place in Tesla’s ecosystem:
Buyer beware: Matthews International stole Tesla’s DBE technology and is now subject to an injunction and liable for damages.
During our work with Matthews, we caught them red-handed copying our technology—including proprietary software and sensitive mechanical designs—into… https://t.co/Toc8ilakeM
— Bonne Eggleston (@BonneEggleston) March 10, 2026
Tesla calls this a big win and warns other companies: “Buyer beware—don’t buy from thieves.”
Matthews hit back with a press release claiming victory. They say an arbitrator ruled they can keep selling their own DBE equipment to anyone and rejected Tesla’s request for a total sales ban. They call Tesla’s claims “nonsense” and insist their 20-year-old tech is independent. Both sides are spinning the same narrow ruling: Matthews can sell their version, but they’re blocked from using Tesla’s specific secrets.
What are Tesla’s Current Legal Options
The case isn’t over—it’s moving to the damages phase. Tesla can:
- Push forward in court or arbitration to calculate and collect huge financial penalties (potentially $1 billion+ if willful theft is proven).
- Enforce the permanent injunction with contempt charges, fines, or even jail time if Matthews violates it.
- Challenge Matthews’ new patents that allegedly copy Tesla’s work, asking courts to invalidate them or add Tesla as co-inventor.
- Seek extra damages, lawyer fees, and possibly punitive awards under the federal Defend Trade Secrets Act and California law.
Tesla could also refer evidence to federal prosecutors for possible criminal trade-secret charges (rare but serious). Settlement is always possible, but Tesla’s fiery public response suggests they want full accountability.
This isn’t just corporate drama. It shows why trade secrets matter even when Tesla open-sources some patents, confidential know-how shared in trust must stay protected. For the EV industry, it’s a reminder: steal from your biggest customer, and you risk losing everything.

Tesla Cybercab includes this small but significant feature
The Cybercab is Tesla’s big plan to introduce fully autonomous ride-sharing in a seamless fashion. In fact, the Full Self-Driving suite was geared toward alleviating the need to manually drive vehicles.
Tesla Cybercab manufacturing is strikingly close, as the company is still aiming for an April start date. But small and significant features are still being identified for the first time as production units appear all over the country for testing and for regulatory events, like one yesterday in Washington, D.C.
The Cybercab is Tesla’s big plan to introduce fully autonomous ride-sharing in a seamless fashion. In fact, the Full Self-Driving suite was geared toward alleviating the need to manually drive vehicles.
This was for everyone, including the disabled, who are widely reliant on ride-sharing platforms, family members, and medical shuttles for transportation of any kind. Cybercab aims to change that, and Tesla evidently put a focus on those riders while developing the vehicle, evident in a small but significant feature revealed during its appearance in the Nation’s Capital.

Tesla has implemented Braille within the Cybercab to make it easier for blind passengers to utilize the vehicle. On both the ‘Stop/Hazard Lights’ button and the Door Releases, Tesla has placed Braille so that blind passengers can navigate their way through the vehicle:

We have braille on the interior door releases as well

This is a great addition to the Cybercab, especially as Full Self-Driving has been partially pointed at as a solution for those with disabilities that would keep them from driving themselves from place to place.
It truly is a great addition and just another way that Tesla is showing they are making this massive product inclusive for everyone out there, including those who have not been able to drive due to not having vision.
The Cybercab is set to enter mass production sometime in April, and it will be responsible for launching Tesla’s massive plans for an autonomous ride-sharing program.

Tesla and xAI team up on massive new project
It is the latest move by a Musk company to automate, streamline, and reduce the manual, monotonous, and tedious work currently performed by humans through AI and robotics development. Digital Optimus will be capable of processing and actioning the past five seconds of a real-time computer screen video and keyboard and mouse actions.
Elon Musk teased a massive new project, to be developed jointly by Tesla and xAI, called “Digital Optimus” or “Macrohard,” the first development under Tesla’s investment agreement with xAI.
Musk announced on X that Digital Optimus will “be capable of emulating the function of entire companies.”
Macrohard or Digital Optimus is a joint xAI-Tesla project, coming as part of Tesla’s investment agreement with xAI.

It is the latest move by a Musk company to automate, streamline, and reduce the manual, monotonous, and tedious work currently performed by humans through AI and robotics development. Digital Optimus will be capable of processing and actioning the past five seconds of a real-time computer screen video and keyboard and mouse actions.
Essentially, it will be an AI version of a desk worker in many capacities, including accounting, HR tasks, and others.
Musk said:
“Grok is the master conductor/navigator with deep understanding of the world to direct digital Optimus, which is processing and actioning the past 5 secs of real-time computer screen video and keyboard/mouse actions. Grok is like a much more advanced and sophisticated version of turn-by-turn navigation software. You can think of it as Digital Optimus AI being System 1 (instinctive part of the mind) and Grok being System 2. (thinking part of the mind).”
Its key applications would be used for enterprise automation, simulating entire companies, high-volume repetitive tasks, and potentially, future hybrid use with the Optimus robot, which would handle physical tasks, while Digital Optimus would handle the clerical work.
The creation of a digital AI suite like Digital Optimus would help companies save time and money, as well as become more efficient in their operations through massive scalability. However, there will undoubtedly be concerns from people who are skeptical of a fully-integrated AI workhorse like this one.
From an energy consumption perspective and just a general concern for the human workforce, these types of AI projects are polarizing in nature.
However, Digital Optimus would be a great digital counterpart to Tesla’s physical Optimus robot, as it would be a hyper-efficient addition to any company that is looking for more production for less cost.
Musk maintains that there is no other company on Earth that will be able to do this.
