- BMW is planning an all-electric i4 Convertible for 2028, internally codenamed NA3 and riding on the Neue Klasse platform that underpins the new i3 sedan, per BMWBLOG sources.
- BMW is also building an i4 Coupe (codename NA2) on the same architecture around the same time, with the i4 Gran Coupe ending production next year and leaving the badge idle for roughly a year.
- The Maserati GranCabrio Folgore is currently the only new EV convertible on sale in the US at $206,095 with 229 miles of EPA range, and Maserati has been telling dealers to cut up to $85,000 off electric Folgore models.
- Neue Klasse architecture gives the i3 sedan a 440-mile EPA range on an 800-volt system with 400 kW charging and a native NACS port — enough headroom that a convertible version would still clear 350 miles.
- BMW's existing customer base already supports the body style: the 4 Series family sold 39,379 units in the US last year and the i4 added another 20,114, giving the i4 Convertible a built-in dealer and buyer pipeline.
- Competing electric roadsters have stalled: Polestar pushed the 6 back behind the Polestar 7, Tesla has been promising a new Roadster since 2017 and just delayed demos again, and Audi scrapped its electric sports car plans outright.
Why it matters: Convertibles are a structurally tough EV segment, and the only current US option costs $206,095 — BMW gets around the low-volume problem because the Neue Klasse platform is already funded across its lineup and it already sells 4 Series convertibles at scale. That math is why a $200K Maserati is the only alternative and why every startup roadster program has slipped.
