Tesla is making a big change by adding 5G modems to its cars. Until now, vehicles like the new Model Y, Cybertruck, and updated Model 3 used LTE (4G) modems. The shift to 5G is a first for Tesla.
The new modem, called “Telematics Control Unit (TCU) – GEN II ” was spotted in Tesla’s parts catalog by Green, a well-known Tesla hacker on X. It’s expected to be installed in new vehicles as supplies become available.
What 5G Means for Tesla Owners
5G is faster than LTE. It can reach speeds up to 1000 Mbps (1 Gbps). LTE speeds range from 20 Mbps to 100 Mbps.
But 5G coverage isn’t everywhere yet. Cities will see the biggest improvement. Rural and suburban areas might still use LTE or even 3G in some cases.
Model Y Buyers Might Get LTE or 5G
The new Model Y could come with either the older LTE modem (Gen I) or the new 5G modem (Gen II).
Buyers won’t know which one they’re getting until the car arrives. Green confirmed on X that both options are valid for the Model Y.
Can Owners Upgrade to 5G Later?
Tesla now sells parts directly to customers, but the 5G modem isn’t listed with a price. Installing it requires programming by Tesla Service or a trained technician. Owners can’t do it themselves.
Tesla might offer a retrofit service in the future, but parts are still limited. If 5G becomes essential, owners might be able to request an upgrade through Tesla Service as availability improves.
In the past, Tesla offered a paid upgrade from 3G to LTE when AT&T shut down its 3G network. This ensured older vehicles stayed connected.
The move to 5G shows Tesla’s focus on cellular connectivity for now. Direct satellite support through Starlink isn’t available yet, but it could come later. For now, using a Starlink Mini on the car’s roof is a workaround for faster internet.
This upgrade keeps Tesla vehicles connected and ready for faster networks as 5G expands.
