The 51 kWh is all based on what InsideEVs published right after the Model T Moment announcement last year. At the time, no one else said anything about. Every other news source that was there (including us), heard Jim Farley, Doug Field, and Alan Clarke defer all questions about battery size. I do think the battery is going to be small but not that small. I'm guessing maybe 60 kWh for standard range and 230 miles of range. But that is definitely just a guess.51 kWh and 200-220 miles of range are disappointing
