Tesla Semi features a central driving position and advanced electric powertrain for heavy-duty hauling

The Tesla Semi is a Class 8 electric day-cab tractor designed for efficient, long-haul freight transport. It features a central driving position, similar to the McLaren F1, which provides the operator with enhanced visibility and eliminates the need for large, traditional side-view mirrors. The vehicle utilizes a 6x4 drivetrain with four powered wheels, and its electric motors are built in-house by Tesla. The truck incorporates a sophisticated thermal management system that shares components with the Cybertruck, allowing for efficient heat scavenging between the cabin, battery, and drive units. Charging is supported by a 1.2 MW peak capacity system, which can charge the vehicle from 5% to 80% in approximately 40 minutes. The truck uses pneumatic brakes with a brake-by-wire system, and it is equipped with a proprietary communication and plug type for trailer integration, including support for electric transport refrigeration units (ePTO). The vehicle's design prioritizes aerodynamics and driver ergonomics, with a focus on reducing driver fatigue and operational costs through high uptime and simplified maintenance.
