The performance of the vehicular split compressor differential gas turbine (SCDGT) engine is compared to that of the variable geometry free power turbine (FPT) engine. Fuel consumption, engine braking, acceleration, and starting are considered, and it is concluded that the SCDGT has several important advantages. The SCDGT engine needs no speed-changing gearbox for forward drive, its part-load fuel consumption is at least as good as that of the FPT engine, and its acceleration and ease of starting are better.
