Overview
- Spy photos published July 28–29 show a BMW prototype codenamed NA3 that adopts Neue Klasse styling and is clearly an i4 two-door convertible in active road testing.
- The car appears to sit on BMW’s 800‑volt Neue Klasse architecture and observers say exterior bits match the i4 50 xDrive dual‑motor specification, though BMW has not confirmed powertrain or battery figures.
- The prototype uses a folding cloth soft top and a noticeably shorter two‑plus‑two layout than the i3 sedan, raising questions about rear‑seat space and whether the full 108.7 kWh battery can fit under the reinforced floor.
- BMW plans to sell the electric convertible alongside visually similar combustion 4 Series drop‑tops and to develop electric M coupe and convertible variants as part of a mixed powertrain strategy.
- BMW is targeting a European launch around 2028 and reports say U.S. deliveries could follow later depending on Neue Klasse production and market allocations.
