For 2002, the EX257s were offered to customers for the first time. Two American teams, KnightHawk Racing and Intersport Racing, would seize the opportunity and purchase one chassis each, for competition throughout the American Le Mans Series season. Improvements to the EX257 allowed for greater durability, and it was shown at Sebring with Intersport taking the LMP675 win and seventh overall, while KnightHawk took third in LMP675. Over the rest of the season, the pair of EX257s dominated the series, taking four more wins total. KnightHawk took the LMP675 championship by a single point over Intersport. Also, for the final four races of the season, a third EX257 would join the series, in the hands of Dyson Racing, who managed fifth in the championship, even with running a handful of races.
