There is usually a happy medium in life, which is the case with the Chevrolet Corvette Grand Sport. It's more exclusive than a base model Corvette, yet not as expensive as a Z06. How well does it perform? We brought it to the Edmunds test track to find out. Acceleration was tested with 0-60 and quarter-mile tests, while braking was calculated using 60-0. Handling tests included a timed slalom and two trips around a skid pad to generate a lateral acceleration calculation.
