6AYEM-GT

The 6AYEM-GT is the higher-output common-rail variant of the 6-cylinder, 155x180 mm, 20.38 L AY-family engine, offered under an IMO Tier II rating banner reaching up to 749 kW/1018 mhp at 2000 rpm. The catalogue presents the rated-output row jointly for the GT and ET variants without a per-model split, so individual power figures are not stated here.
