There’s the Smart EQ fortwo and forfour That could fit into your requirements. However they ony have around 78mile electric range, whitch if your only tootling around town itwould probably be ok.
You say you already have a Picanto, is that auto? If so you will be acustomed to the auto box and its pitfals that would aso be in the i10.
Unfortunately even city cars these days are getting larger, so there isn’t really alot to choose from unfortunately.
