Tesla Semi truck unveil set for September.
The busiest man in tech already faces looming deadlines for getting a battery factory up to speed, the Model 3 out the door, and a secret payload (probably a spy satellite) into orbit.
Turns out he’s got a team working on a battery-powered truck he will reveal in September, as part of his master plan to shift the world to sustainable energy.
Plans for such a truck, if they truly exist, almost certainly call for batteries alone, because Musk disdains hybrids and range-extended electrics like the Chevrolet Volt.
The frame of a semi is essentially a pair of long steel rails, which could easily support a battery pack (which also could go behind the cab).
Ditching the internal combustion engine saves more space, and lets you use smaller motors on each axle or even each wheel.
