By Tom Berg
The StarShip tractor-trailer will get mpg that's "better than anyone else," but the former owner-operator, whose work with aerodynamics goes back to the 80s, is not announcing a target number.
The diesel and original manual transmission are replaced by a Power Control and Accessory Subsystem and a pair of inverter-charger units.

Motors use as much as 150 kilowatts to make up to 400 peak hp and 880 lb-ft.
