All the german marques sell a mid size lwb in china, 5-series, A6, E-class...even the STS had one.
This just looks like a push for the trend in a narrower vehicle. The 5 grew quite a bit so there may have been need for a car with rear legroom that wasn't so wide. I know in European cities vehicle width is a huge concern as it would exclude you from some streets.
