I do not know if it is better looking, it is a very successful evolution in the design, because also in the pre LCI it was perhaps very conservative, but everything has its moment so the design is evolving towards this, gradually returning to the straight lines as in the 7 series, for BMW after 25 years of smooth cornering, this fits perfectly.
Here there was room to improve, but for example in the Mercedes E there was not so much because it was already very good in itself and the LCI does not improve it, it just changes it
The progression will be to continue this trend towards the rest of the car body of future models, on the next 5, 7, as seen in the 4GC, 4 coupe and others to come.
