So I've heard rumors among numerous news outlets that Tesla is working on a new electric "supertruck". If this is true, Tesla Motors is straying far away from its original master plan. They are supposed to be scaling down in favor of more affordable vehicles and NOT expanding their variety of toys for the very rich.
Tesla's secret plan is to scale down with each successive model to make electric cars affordable as quickly as possible. R&D is paid for by success of preceding models, and each successive model would become significantly cheaper. Based on the introduction of the Model X and the supposed creation of this "supertruck", it appears they are moving instead toward a plan of making an electric supercar for every category of vehicle.
I just hope they don't make another Roadster; the electric sportscar stuff should be handled by Detroit Electric until Tesla starts selling a car that the American public can afford.
