The Lexus LFA is an entirely new pursuit, both for supercars and for Lexus. How much potential does the LFA have? To find out we brought it to the Edmunds.com 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.
