Tesla’s latest Summer 2026 software update, version 2026.26.6.5, gives Grok a much bigger role inside the car.
What started as an AI assistant mainly used for casual questions and conversation can now control a wide range of everyday vehicle functions, allowing drivers to rely less on the central touchscreen.
The upgrade is a major step forward for Tesla’s in-car voice experience, but it also comes with an important limitation. A large number of older Tesla owners will not get access to the full set of new features because of the processor fitted to their vehicles.
Grok Can Now Handle Far More Than Simple Voice Requests
Drive Tesla Canada tested 170 different voice commands and found that Grok successfully completed 116 of them, giving it a success rate of around 68 percent without requiring driver intervention.
The new system can handle several climate and cabin functions, including temperature adjustments, fan speed, windshield defogging, and seat heating.
Drivers can also use voice commands to fold the side mirrors, open the glovebox, and adjust the windshield wipers.
Navigation and security controls are part of the upgrade as well. Grok can search for nearby Tesla Superchargers, turn Sentry Mode on or off, and save Dashcam footage through a simple voice request.
One of the most useful additions is the ability to understand several instructions in the same sentence. A driver can ask Grok to fold the mirrors, turn on the wipers, and lower the cabin temperature, and the system can carry out all three actions in one go.
This is cool, you can now give Grok a ton of commands at once in your Tesla and it’ll do them all together.

• Fold mirrors
• Turn on wipers to fastest setting
• Change temp to 65°
• Open self-driving app

Older Intel Atom Teslas Miss Out
The downside is that Tesla is limiting the full voice control experience to vehicles equipped with AMD Ryzen processors.
Older cars running Intel Atom hardware may still receive the software update, but they will not gain access to the same expanded set of Grok commands.
For owners of compatible vehicles, Grok can be activated in three ways: by saying “Hey Grok,” by pressing and holding the voice control button on the steering wheel, or by opening it from the app launcher on the center display.
ArabGT Opinion
Grok’s evolution from a conversational feature into a useful in-car control tool feels like a natural direction for Tesla.
Voice control can reduce the need to dig through menus on the touchscreen, which is especially useful for simple tasks such as changing the temperature, adjusting the wipers, or finding a charging station.
The bigger issue is what this update says about the lifespan of modern car hardware. As vehicles become more dependent on software and computing power, the processor inside the car can directly determine which features owners receive in the future.
That could make onboard computing hardware an increasingly important consideration when buying a used EV, especially as newer software features begin to rely on more powerful processors.
What Do You Think?
Would you trust voice control to replace more physical buttons inside a car, or do traditional controls still feel safer and easier to use while driving?
