DACIA Spring battery pack benchmarking: I live and work in Romania. Its my second home. Recently I have seen so many Dacia Spring in town. Electric revolution is coming to Romania. Dacia Spring was in the Top 10 Best Selling BEV Models in Europe in 2022. Sales Volume was 48535. It is though manufactured in China at a Plant jointly owned by Renault, Nissan and Dongfeng Motors.
