The first BMW i4 Convertible has been spied testing, and like the current petrol-powered 4 Series Convertible it'll feature a two-plus-two layout and a folding soft-top. The i4 Convertible will have essentially no competition, with electric convertibles being extremely rare. These will continue to be produced alongside Neue Klasse electric models as BMW somewhat hedges its bets on customer demand for electric and petrol powertrains. Autocar has reported the i4 Convertible will also be joined by a coupe version, also wearing the i4 nameplate. MORE: Explore the BMW i4 showroom
