The description of what the "sports handling" mode does is rather vague in the owners manual. I understand that it somewhat mutes the ESP nannies. In other AMGs I've had, this was my preferred mode to track the car in. I seem to remember reading somewhere that, among other things, in the GLA 45 it locks the torque split between front and rear at 50/50. I hope this is true but can't confirm this. does anyone know?
