Like 90% of trucks and SUVs, most Cybertruck will never leave the pavement. But Tesla is setting the stage for a significant upgrade that promises to elevate its off-road performance for the small group of owners that may actually get the Cybertruck a little dirty. The feature will be in an upcoming software update, confirmed by the lead Tesla Cybertruck engineer.
Upcoming Update
Traditionally, the acquisition of a vehicle came with a fixed set of features, with any upgrades necessitating physical modifications or replacements. However, Tesla has redefined this paradigm by implementing software-defined vehicles.
Yes, we have dual and tri and testing out both the mechanical lockers as well as E-Locker for Tri rear. Coming via OTA soon

Tesla's Cybertruck is undergoing rigorous testing to perfect the integration of locking differentials. Wes Morrill, Cybertruck Lead Engineer, revealed that the team is experimenting with both mechanical and electronic locking systems for the rear axles and will enable them in an upcoming software update. The fact that Tesla is already testing the feature in the Cybertruck means that it could be released imminently. at least if testing goes well.
The Mechanics of Locking Differentials
In vehicles, a differential allows wheels on an axle to rotate at different speeds, which is crucial for turning. However, in off-road scenarios, this can lead to a wheel spinning freely if it loses traction, limiting forward movement. Locking differentials solve this by forcing both wheels on an axle to move at the same speed, ensuring that power is efficiently directed to the wheel with better grip, enhancing off-road capability.
The driver can engage Locking differentials manually or automatically, adapting to changes in traction on the fly. Tesla's Cybertruck is poised to feature electronic locking differentials, utilizing electromagnets or solenoids controlled by the vehicle's software. This enables precise, dynamic adjustment to driving conditions, ensuring optimal traction across diverse terrains.
This technology represents a significant advancement in vehicle design, merging mechanical robustness with digital intelligence. By automatically detecting and responding to traction needs, the Cybertruck's locking differentials will offer drivers a superior off-road experience, showcasing the potential of integrating software solutions with traditional automotive mechanisms for improved performance.
