So confidence inspiring is the Porsche Boxster that we felt comfortable switching off the electronic wizardry of Porsche’s Stability Management, which uses ABS (antilock brakes), ASC (anti-slip, or stability, control), EDC (engine drag control), and ABD (automatic brake differential) to help keep the car from sliding and going off-course. At first we were fearful, because on a road like the Cherohola, bad things can happen quickly. But we found the level of control and confidence the Boxster provides compensated for the lack of electronic intervention.
