Overview
The BMW i4 (model code G26) is a battery electric compact executive car produced by BMW since 2021. It has a five-door liftback body style and is marketed as a four-door coupé. The initial concept version, named BMW i Vision Dynamics, debuted at the 2017 Frankfurt Motor Show.

As a rule, each extra 1J of width wants roughly +8–10 ET to keep the wheel tucked. The exact offset and any spacer are confirmed by the fit-check.
Development began in 2018 with an investment of €200 million to convert Munich's assembly line for series production. The i4 was revealed fully production-ready in March 2021 and went on sale as a 2022 model in November 2021.
