Mike Spinelli of DRIVE sat down with Albert Biermann, BMW M Chief Engineer, to chat on the new 2015 BMW M4 Coupe.

Biermann takes about how they approached the car, why it’s so good, and why it’s all about steering. The electric steering that is. Earlier this year, we also spent some time with the M engineer at the M Training Facility in Nurburgring where, underneath an M4 Coupe, he shared with us the technology and tuning that went into the development of what some called the best M3 (well, M4) to date.

As always, Spinelli asks some interesting questions so it’s a well spent 21 minutes.

Let’s have a look.
