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.

SpaceX set to launch astronauts and a classified Falcon Heavy mission on the same day
SpaceX plans three launches Thursday, including Crew-13 astronauts and Falcon Heavy’s first classified NRO mission.
SpaceX is lining up one of the busiest single days in its history, and the company offered a preview on Wednesday morning with a simple post on X: “Sunrise at pad 40.” The video and photos show Falcon 9 standing at Space Launch Complex 40 at Cape Canaveral, roughly a day before it is scheduled to carry four astronauts to the International Space Station.
That launch is only the first of three SpaceX missions planned for Thursday, October 1, across both coasts.

Crew-13 is targeting liftoff at 11:10 a.m. ET, with a backup opportunity Friday at 10:47 a.m. ET. NASA astronaut Jessica Watkins will command the mission, with NASA’s Luke Delaney as pilot and Canadian Space Agency astronaut Joshua Kutryk and Roscosmos cosmonaut Sergey Teteryatnikov serving as mission specialists. According to NASA, Dragon is set to dock with the forward port of the station’s Harmony module around 8 p.m. ET, less than nine hours after launch. Watkins is the only member of the crew who has flown before, and Kutryk will become the first Canadian to reach orbit through NASA’s Commercial Crew Program.
The Falcon 9 booster is flying for the third time after supporting Crew-12 and a Starlink mission, and it will attempt a landing at Landing Zone 40 beside the pad. That site made its debut in February when the Crew-12 booster touched down there, as Teslarati reported at the time. Crew-13 will relieve the Crew-12 astronauts, who have been aboard the station since the middle of February.
On the West Coast, another Falcon 9 is scheduled to lift off from Vandenberg Space Force Base in a window running from 2:18 to 3:16 p.m. ET, a flight NASASpaceflight lists as a Transporter rideshare mission.
The day is set to close at 11:53 p.m. ET, when Falcon Heavy launches from Launch Complex 39A with NROL-97, the first National Reconnaissance Office payload ever to fly on the rocket. SpaceX rolled the vehicle out to the pad Tuesday night. Its two side boosters, which previously flew GOES-U, ViaSat-3 F3 and NASA’s Roman Space Telescope, will return to Landing Zones 1 and 2, while a new center core will be expended in the Atlantic. The Roman launch took place on August 30, so NROL-97 will come barely a month later as Falcon Heavy’s third flight of 2026 and 14th overall.
NASA taps SpaceX to launch the telescope that could unlock new worlds
If all three Florida boosters land as planned, it would be the first time the Space Coast has seen landings at LZ-40, LZ-1 and LZ-2 on the same day, according to the Orlando Sentinel, which has warned residents in Brevard, Orange and Volusia counties that more than one sonic boom is possible.
The schedule arrives just three days after Starship reached orbit for the first time on Flight 14 from Starbase, Texas, deploying 26 Starlink V3 satellites. If Thursday’s missions stay on time, SpaceX will have flown Starship, Falcon 9 and Falcon Heavy from four different pads in about four days.
Crew-13 is also the start of a longer run for Dragon. NASA recently added Crew-15, Crew-16 and Crew-17 to SpaceX’s contract in a $946 million modification, keeping Dragon as the agency’s only operational ride to the station while Boeing’s Starliner remains grounded.

Tesla Cybercab and Semi have more in common than you might think
Although the two vehicles are built for completely different use cases, Tesla utilized engineering expertise while developing both the Cybercab and Semi to build a thermal architecture that would fit both vehicles. Of course, with some slight revisions.
The development was noted by Lars Moravy and Dan Priestley last week at Tesla’s Semi Handover event in Sparks, Nevada, where the company showed off its dedicated production facility for the Class 8 truck.
🚨 Tesla designed the integrated thermal systems for Cybercab and Semi at the same time as the vehicles were both in development
Tesla wanted to build one thermal system that worked with both vehicles, apart from small modifications.
Semi and Cybercab share parts 🤯 pic.twitter.com/KmzSsUbrcg
— TESLARATI (@Teslarati) September 25, 2026
Tesla’s decision to develop one thermal architecture for both the Cybercab and Semi is one of the more revealing engineering choices in the company’s 2026 lineup:
“We designed it at the same time we designed the Cybercab and we said okay we’re going to take our most efficient vehicle and our biggest vehicle and we’re going to take one thermal system and make it work for both.”
Core parts, meaning the compressor, pumps, and heat exchangers, are shared, with only modest changes to cooling-loop sizing and a larger radiator on the truck. The result, they said, is a compressor and thermal stack already proven across millions of miles, delivering “reliability from day one.”
Priestley also highlighted a practical payoff of the indirect design:
“There’s no AC lines, there’s no refrigerant lines…It comes from the factory fully charged, sealed with refrigerant, and it just exchanges coolant. It doesn’t actually run refrigerant up to the front of the vehicle.”
This eliminates potentially leak-prone plumbing that would otherwise require hands-on service, reducing overall uptime and potentially cutting into business margins. The megamanifold runs cabin HVAC and every powertrain heating and cooling loop at once, recapturing waste heat from motors and the battery instead of dumping it the way a diesel engine does.
The approach is just the latest chapter in a continuing story of stretching thermal solutions across wildly different vehicles. Model Y’s Octovalve evolved into the Super Manifold used on Cybertruck, and later Model S/X refreshes. Cybercab then introduced Supermanifold V3, which Tesla says is 80 percent automated to build and 38 percent more efficient than typical automotive thermal systems.
This thermal system is also shared with Cybercab – one thermal system for both our most efficient vehicle & our biggest vehicle
— Tesla Semi (@tesla_semi) September 25, 2026
Tesla has done the same with the 4680 cells, both being utilized in the Cybertruck and Semi, and with heat-pump compressors that Priestley noted were already common across the passenger-car fleet.
Concurrent development of crucial vehicle elements buys scale and reliability that a truck-only thermal system could not match. High-volume passenger car parts are cheaper and more accessible, which can give fleets a sealed, low-maintenance loop of operation from their first day of operation.
For owners and operators, that translates into less energy spent on cabin heat in the colder months, fewer refrigerant-related repairs, and a thermal architecture already stress-tested at passenger-car volumes before the first high-volume Semi left the lines in Nevada.

Elon Musk weather update tips Tesla Roadster speculation into Plaid Mode
Tesla CEO Elon Musk certainly tipped off some details of the Tesla Roadster event with a broadening of information regarding the company’s decision to delay the unveiling for two weeks.
For years, people have speculated about what the Roadster will be capable of. While there have been plenty of things said about what it *could* do, we have not seen or been told by Tesla what it will actually be capable of.
However, over the past few days, Tesla’s weather updates have truly pushed the speculation into Plaid Mode, basically all but confirming the car will have some sort of aerial capability — whether that would be hovering or fully flying remains to be seen — but it definitely seems that it will be able to leave the ground intentionally.
“Because this event can only be held outdoors…”
Tesla posted on Monday that it would delay the Roadster event until October 15, and it indicated that it had to do this because the event “can only be held outdoors.”
With the potential SpaceX collaboration to develop cold-gas thrusters that will help the vehicle go airborne, doing this indoors is probably not a safe, or even plausible, possibility.
Roadster event update
We’ve been tracking the weather closely with local meteorologists, but given the severe conditions predicted & because this event can only be held outdoors, we’ve made the difficult decision to reschedule.
New date is October 15. Additional details to…

FAA Airspace Restriction
The FAA gave Tesla a Temporary Flight Restriction (TFR) for 10,000 feet above ground level, much higher than the typical 2,000-foot restrictions that are usually placed at SpaceX’s McGregor, Texas site.
Tesla Roadster event requires restricted airspace, and the FAA obliges
Some have said that this massive increase is due to Tesla’s need to restrict unauthorized drone use for spying on the event.
Elon Admits High Winds
“Due to high winds, the new Roadster demo is postponed by 2 weeks,” Musk said in a post on X yesterday.

A reply reading, “What’s strong wind got to do with a car demo with four grounded wheels?” was directly below Musk’s post, satirically and sarcastically probing for more details.
All signs are pointing toward an aerial demonstration for the Roadster.
