The Infiniti M56 S offers consumers the best of both worlds: sportiness and luxury. To find out just how well it does in these categories, we took it to the Edmunds test track. 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.
