The BMW i4 Convertible will wear Neue Klasse styling, though it won't copy the new i3 sedan's look exactly, these spy photos show. Despite a camouflage wrap, we can spot a more upright front end, with flatter headlights and a taller grille than the i3 sedan. Despite sharing its name with the outgoing i4, the new convertible, expected for the 2029 model year, is more of an electric evolution of the current 4-series.
