Black Test Car (黒の試走車, Kuro no shisō-sha) is a 1962 Japanese crime thriller film directed by Yasuzo Masumura, co-written by Kazuo Funahashi and Yoshihiro Ishimatsu, and based on the novel of the same name by Toshiyuki Kajiyama.
Asahina, a member of the Tiger's planning department, has his girlfriend Masako entertain Mawatari, head of Yamato's planning department and former colonel in the Manchukuo Imperial Army, in order to get information about Yamato's car model.
Mori agrees and gives Onoda the specs of the design of Yamato's new car model Mypet.
Nevertheless, director Oguri orders Tiger to start production on more Pioneer car models.
Hiraki reveals that he was forced into becoming a spy for Yamato Motors because Mawatari and Motoba, a Yamato spy who delivered information to Tiger, threatened to reveal to the public his affair with Katsuko, another Yamato spy, that he had the nurse spy for Yamato by bugging the hospital room of his father-in-law, the President of Tiger Motors, and that he delivered the first Pioneer to a man called Yoshino (who served in the Manchukuo Imperial Army under Mawatari's command), who intentionally wrecked the car by having it collide with the train and slander Tiger by claiming that it had broken after eighteen miles.
