From its first introduction the ZG348 very quickly proved to be an outright winner. During its first season it qualified on pole position in the LMP2 class at Le Mans, and went on to finish second in class.

The engine also finished second in the Le Mans Series (LMS) championship powering a Gibson ‘Zytek’ 04S LMP2 chassis and it also achieved success in the American Le Mans Series (ALMS), taking an outright win at Laguna Seca, whilst breaking the track’s lap record in 2005 by over 1.7 seconds.
