I think “figured it out” is a strong statement.If its being delayed to shoehorn an EREV option, please don’t put the engine in the frunk. Scout Terra has it figured out!
T3 has always been planned as a smaller truck.It really wouldn't make sense for Ford to have a Gen-2 Lightning and the "T3" electric truck that will be the same size. They would steal sales away from each other and they are already facing an issue of potential low volume. Sure, some buyers may prefer one over the other, but I doubt Ford will spend the money to develop, produce, and market both.
It may be that Ford is spending some resources developing a Gen-2 Lighting just to keep the possibility open as a contingency plan in case they axe the T3 or the market shifts drastically.
