The Cybertruck’s revolutionary steer-by-wire mechanism has been a hot topic among Tesla enthusiasts and critics alike. While supporters of the technology have been eagerly anticipating this breakthrough, skeptics have predictably expressed doubts. Tesla claims to have utilized a high-speed communication protocol to transmit signals from the steering wheel to the front and rear axle steering motors. This ensures an instantaneous response, sometimes even surpassing the speed of a traditional mechanical linkage.
Although this may seem counterintuitive, there is a logical explanation. When the right medium is employed, electricity can travel at a remarkable speed. While a conventional steering rod-and-rack system may appear to provide a direct connection, there are rubber interconnects and play between components that result in the loss of some steering movements and a slight delay.
Initial test drivers of the Cybertruck have reported no discernible difference between the steer-by-wire system and traditional mechanical steering. However, what may be perfectly acceptable for an inexperienced driver could prove to be a nightmare for a professional race car driver. Renowned driver Craig Coker recently put the Cybertruck to the test both on the racetrack and off-road, confirming that the steer-by-wire system is finely calibrated for even the most demanding scenarios.
For those unfamiliar with Craig, he is a seasoned pilot who competes for the Unplugged Performance race team in various competitions. He has also set numerous track records with the team’s modified Tesla Model S, known as “The Dark Helmet.” In addition to his racing endeavors, Craig Coker frequently conducts tests for the Unplugged Performance team, making him the ideal candidate to evaluate the Cybertruck’s performance under racing conditions.
Craig had the opportunity to race the Cybertruck at the Buttonwillow racetrack and described the experience as exhilarating. Due to its substantial weight and soft suspension, the electric pickup does not handle like a sports car, more closely resembling a boat. However, it still provides an enjoyable driving experience. Craig also tested the Cybertruck off-road at the Kings of the Hammers event and shared his insights on the vehicle’s steer-by-wire system.
Initially skeptical of the absence of a physical connection between the steering wheel and the wheels, Craig admits that losing the mechanical feedback makes it challenging to trust the car when pushing it to its limits, particularly for a race driver. However, after extensive testing in various terrains, he was impressed with what Tesla has achieved.
“The steering ratio is exceptional in both everyday driving and extreme situations,” Craig shared on X. “You can truly feel the road! The connection between the driver and the vehicle is crucial to me. When I slam on the brakes and the ABS engages, I want to feel that vibration all the way to the tires. If you can sense the tires, you can effectively manage traction!”
Craig was also surprised by the impressive performance of the Cybertruck even without functional differential locks. These locks are beneficial in situations where three or even two wheels lose traction, and they are particularly important on a racetrack, as they enhance grip during cornering. Hopefully, Tesla will soon address this issue through a software update, transforming the Cybertruck into a formidable off-road vehicle.
Now, let’s delve into the concept of Steer By Wire!
Initially, I had reservations about this feature on the Cybertruck. In fact, I was apprehensive about it. I was concerned that I would lose the tactile sensation and the feedback from the vehicle that instills confidence when pushing its limits. However, Tesla has incorporated something remarkable…
