The brakes on BMW’s new 3-Series feature a host of life-saving tricks packed for the first time into one vehicle. They anticipate an emergency stop and cinch the pads closer to the rotors, so they engage faster. And because they resist fading during long descents, you can stop quickly at the bottom. They also squeeze the calipers intermittently in the rain to keep the pads and rotors dry and, when stopped on hills, hold the car while you move to the accelerator.
