Don’t confuse gross profit with net profit. Every person on that 100 person skunkworks team plus the entire T3 design, engineering and testing team plus all the folks working on next gen batteries and platforms and future vehicles are an expense without a revenue stream.
You're looking at a division that is staffed for and working on 8-10 vehicles (more counting Europe) but only selling 3 and developing new platforms, technologies and processes and building new plants (construction is capital but there is still a lot of expense).
All of those costs go against net profit and it’s virtually impossible to turn a net profit more new EVs are on the street generating revenue and profits.
