Tesla Semi proves ice stability in Alaska testing

Tesla released footage showing its all-electric Class 8 Semi truck undergoing rigorous winter testing on frozen roads in Alaska. The truck features an in-house Vehicle Dynamics Control (VDC) system and a tri-motor drivetrain on the rear axles that adjusts torque to individual wheels within milliseconds. This rapid torque modulation enhances traction and stability on slippery surfaces, outperforming traditional diesel trucks with slower mechanical systems. The tests included a loaded trailer with concrete blocks and steel bars to simulate real-world hauling conditions and a low center of gravit
