Previously, we have reported that BMW plans to officially release i4 and i4 m in the summer of 2021, but now there is not much exposure to the detailed information about these two cars. A few days ago, foreign media took the road test spy photos of BMW I4 M prototypes on the street.
From the viewpoint of exposure, the appearance of BMW I4 M is not much different from the previously exposed I4 spy photos, but Some details can be disconnected to the M-style identity of the car. For example, you will find the rear view mirror style of the BMW M model, a larger brake caliper, and a wider rear tire size. However, the rest of this car is not obvious. 
According to the presently known news, the relationship between BMW I4 and I4 M does not differ as much as the fuel model. In the BMW fuel model, if there is a M-target model, it usually has a significant change in appearance, interior, and configuration. However, from the currently known information, BMW i4 m is more like a high version of the i4 model, and the appearance changes are not obvious. (Message Source: Motor1)
