Really..... that's very interesting if confirmed. Every recorded test drive I saw, the driver didn't know anything about the car at all. If one actually knew it was a D, that would be excellent. On two I saw, they couldn't even tell the size of the display or such standard basic answers to questions.I believe at least one of the two cars used at the first reveal were dual motor, according to one of the drivers. One of the live-streamed passengers asked.
But seriously, I would think all 50 cars they made in the last month were the same configuration, and the 20 extra ones were for the test drives, engineering analysis, Quality Control teardown, etc. (Trevor of Model3Owners mentioned this.) Unless there's more definitive data, I doubt they are making any other combinations right now besides 'Long Range' battery, RWD, and PUP.
