FYI: Tesla’s Cybertruck pulls ahead in off-road performance after critical software update
Tesla Cybertruck’s Rocky Start with Dual-Motor Setup
At the end of 2023, Tesla began deliveries of their much-anticipated Cybertruck, but the introduction was not without its challenges. Right off the bat, the electric pickup faced criticism as its advanced Full Self-Driving system was not functional, and mechanical differential lockers were inactive. This left the Cybertruck lagging in off-road capabilities, primarily relying on traction control to navigate tricky terrains.
Software Update to the Rescue – Enter Off-Road Mode
Tesla remedied these issues during the summer by rolling out a software update, elevating the Cybertruck’s off-road prowess significantly. Central to this upgrade was the activation of the factory-installed mechanical differential locks, previously dormant. These mechanical assets are critical, with dual-motor versions sporting both front and rear diff locks, while the tri-motor Cyberbeast features a single mechanical locker at the front and a virtual lock at the rear.
Putting Cybertruck to the Test: Roller Simulations
Numerous Cybertruck owners have shared footage demonstrating the vehicle’s enhanced traction under various scenarios, thanks in part to the Off-Road Mode. A compelling test involved placing the vehicle on rollers to assess its electronic decision-making. Initially, with two wheels on solid ground and the other two on rollers, the Cybertruck easily propelled forward in Comfort mode, which doesn’t engage diff locks.
A sterner test emerged with just one wheel having traction, yet the vehicle managed to escape the rollers with impressive agility. When Off-Road Mode was engaged, utilizing both diff locks, the Cybertruck effortlessly maneuvered off the apparatus without delay.
Understanding the Role of Diff Lockers
Mechanical diff lockers enable both wheels on an axle to rotate simultaneously at the same speed, providing crucial traction even if one wheel is airborne. These have been indispensable for off-roading vehicles for decades. With the rise of electric vehicles, companies like Tesla, Ford with its F-150 Lightning, and GMC’s Hummer EV, continue to integrate these vital components, ensuring superior performance in challenging environments.
Conclusion
Tesla’s Cybertruck has made significant strides in recovering from its initial shortcomings, demonstrating that with strategic software updates, electric vehicles can retain and even enhance traditional off-road capabilities. The rapid activation of mechanical differential locks underscores Tesla’s ability to adapt and upgrade its offerings, placing the Cybertruck firmly in the contender seat for innovative electric off-road vehicles.
