Yard Dog Meets Highway King: Why Tesla Semi + Kalmar AutoTT Might Never Shake Hands
The Tesla Semi dominates the open highway with 500-mile range, megawatt charging, and a 25 kW e-PTO for electrified trailers. The Kalmar AutoTT owns the yard — fully autonomous, cab-less, built for 15–25 mph trailer shuffling in mixed-traffic terminals. Both are electric. Both target logistics. But the Semi is a Class 8 highway tractor (82,000 lbs GCWR, Cd 0.36, MCS V4 charging), while the AutoTT is a terminal tractor with zero disclosed specs — no battery capacity, no lift rating, no charging standard, no weight data. They operate in sequential, not overlapping, segments: Tesla delivers to the gate; Kalmar takes over inside. No shared charging protocol, no data bridge, no physical coupling. The Semi’s e-PTO could power a reefer trailer the AutoTT moves, but that’s speculative without AutoTT specs. Until Kalmar reveals battery voltage, charging interface, and tow capacity, this is two silent ships passing in the night — adjacent in the supply chain, disconnected in engineering.
