MINI CEO Stefanie Wurst has stepped down just two weeks after revealing the new Aceman EV.
Wurst launched new Mini Cooper and Countryman models in two brief but eventful years in the role.
She recently announced a new Mini five-door hatchback, completing her overhaul of the British brand.
The reasons for Wurst's shock departure remain unknown - but she will stay with parent company BMW Group in a new job.
Wurst will stay on until the start of August while new Mini CEO Stefan Richmann beds in.
It comes just two weeks after Wurst revealed Mini's first EV-only model Aceman in China's capital Beijing.
