My Dual Motor Long Range Y, built August 15, 2020 (VIN: 36000, 8th character E) definitely has the 990 rear motor. The Performance has the 980. The original batch of LRs had the 980. They also had the Performance VIN (8th character is F while in my LR the 8th character is E). Details on the early LRs here: Model Y Performance Rear Motor Debate *rages* whether there is a performance/efficiency difference. Personally I'd bet there is a performance benefit of the 980 (maybe at the cost of efficiency?).
