For more than 60 years we've been answering the objective questions—How fast? How quick? How much grip?—comprehensively, and with an authority based in experience that our readers have come to rely on. Our testing started back in 1955, a year before the interstate highway system even existed. At that time we went by the name Sports Cars Illustrated, and we tested the old-fashioned way: with a handheld stopwatch and not the high-precision GPS test gear we use today.
