The Masurao (even in its original Ahead based form) also doubled as a test machine for the Trans-Am System, which at that time, was only usable by the original GN Drive-equipped Gundams. Installation of a Trans-Am System usable by GN Drive Tau-equipped mobile suit was possible due to Billy's analysis of the late Professor Eifman's notes on the GN Drive. The Masurao then became the first GN Drive Tau-equipped mobile suit to have and utilize the Trans-Am System, which caused it to glow red and its output to be increased by three-fold for a brief period of time. Furthermore, the Masurao's Trans-Am System was designed to make full use of the mobile suit's two GN Drive Taus, giving it overwhelming output that cannot be achieved with a single GN Drive Tau. While the Masurao has two GN Drive Taus, one installed in each waist-mounted side binder, this is not a Twin Drive System because the two drives are not synchronized.
