Overview
- Multiple outlets citing BMWBLOG report that BMW plans an i4 Convertible, internal codename NA3, for a 2028 debut but BMW has not confirmed the plan.
- The reported design is a two‑door, 2+2 fabric soft‑top built on the Neue Klasse platform and BMW is said to be developing an i4 Coupe (NA2) on the same architecture.
- BMWBLOG published spy photos showing a prototype with near‑final body panels and heavy camouflage, which the site says supports a 2028 testing timeline.
- Coverage notes Neue Klasse’s 800‑volt, long‑range architecture—reported for the i3 at about 440 EPA miles—could offset the weight and range penalties that usually hurt EV convertibles.
- The move would enter a tiny global market for electric convertibles, create roughly a year of overlap with the gas 4 Series convertible (G23) through mid‑2029, and could give dealers a mainstream EV drop‑top to sell.
