In an automotive gas turbine power plant including at least one power turbine rotor and a further turbine rotor driving the compressor of the plant, the latter rotor is undersized with respect to the power consumption by the compressor during normal operation and is augmented from the power turbine rotor. The auxiliaries of the power plant are driven from the power turbine rotor, which is connected to the power output shaft, as well as to the compressor turbine rotor by means of a planetary gearing permitting a braking of the output shaft to standstill without the speed of the power turbine rotor being reduced to below that necessary for operating the auxiliaries.
