Agreed, so isn't the lowest range ("D") model Y only sold with a single motor?A "D" in the 8th position would be for a Single Motor - Standard or Performance Model Y; "E" is for a Dual Motor - Standard Model Y; F is for a Dual Motor - Performance Model Y.
As the eight digit in the VIN is an "E" that means OP has dual motors -> I thought the dual motor was only available on the MYLR and MYP...
