Top Gear features Tesla Semi in factory tour and test drive
Tesla's electric Semi achieves 1.7 kWh/mile efficiency, using roughly 7× the energy of a Model Y at 20× the weight.

Tesla's official Semi account shared footage of Top Gear's factory tour and test drive featuring the production Semi, with host Dan Priestley calling it "maybe the most significant Tesla since the Model 3."
The segment highlights the Semi's efficiency metrics: at 1.7 kWh per mile, the vehicle consumes only about seven times as much energy as a Model Y despite weighing approximately 20 times as much. By comparison, a diesel equivalent uses roughly three times as much energy as the Semi.
The video demonstrates Tesla's focus on real-world validation of the Semi's commercial viability through established media coverage. The efficiency numbers underscore the company's claims about the economics of electric trucking, where energy consumption per ton-mile represents a key competitive advantage.
