A NIOAs of December 1, NIO has sold 80,940 vehicles in 2021 in China. Their battery swap is an option, not an issue, however a poor option IMHO. Tesla only surpassed 100,000 sales per year in 2017 and was selling in Europe and Canada well before then. NIO selling their vehicles in other Countries to take advantage of local incentive programs, and to gain recognition outside China would spur further demand inside China. Does NIO need to expand outside of China, the World's biggest auto market by a wide margin? No. Will they? Yes.
Disclaimer, I do not own NIO, and this deserves another thread here on TMC, so I'll pause the NIO talk.
