Tesla has achieved a 7% improvement on the aero efficiency of the Semi since its debut.

The new Tesla Semi is the long-range 500-mile model.

Tesla recommends a specific set of tires for the Semi to extend its range due to rolling resistance.

When the Tesla Semi reaches highway speed, the torque axle completely disengages to avoid efficiency penalties.

Mile Tesla Semi has transitioned from a hydraulic assist steering system to a fully electric assist system.

Tesla put the driver in the middle of the cab to allow for a rounder front face and narrower upper portion, making the Tesla Semi slicker through the air.
