The AGT 100 is an advanced gas turbine designed for passenger car application. The most significant of its advanced features is the use of structural ceramic components for the hot section of the engine’s flow path. The engine was expressly designed for ceramic components; previously, ceramic materials were simply substituted for metal components. Early experimental builds of the AGT 100 contained many ceramic components and metal substitutes for the more complex ceramic components that were not yet fabricated.

Engine testing has continued to accumulate operating time on the ceramic components that have always been engine-worthy (combustor, regenerator, vanes, rings and spacers, piston ring). Recent engine tests have included both a ceramic turbine rotor and static structure (scroll, vanes, backplates, coupling). Each type and shape of ceramic component has now been engine tested. Development is continuing to improve them even further.
