According to some rumors there is a very big chance to see in the future a Touring version of the BMW M3 E91. Developing a Touring version of the M model which is of course not designed for the circuit but fits best a family driver is not that spectacular mainly considering that the Germans from BMW are not doing very well in this case and I will explain you why shortly.
The main reason I state this is that the eternal German rivals from Audi and Mercedes are already a step ahead in this segment, considering the Avant version of the current RS4 but also the Estate version of Mercedes’ C63 AMG.
Thus, it seems that the high performance wagon models are not something new and I can’t find a good reason for why not to develop the BMW M3 Touring. In the past, the Germans tried to give birth to a Wagon version of the M5 but lastly, the German model wasn’t given the green light for production mainly due to some discrepancies in terms of performance.
