YGK, based in Yamagata Prefecture, said that in its joint project with a team of engineers led by Yoshimasa Hayashi, professor of engineering at Tokai University, it succeeded in developing a 4000 cc sports car engine and a 2000 cc passenger car engine that are quite fuel efficient.
YGK, which put up about 1.5 billion yen for the project, said it plans to manufacture about 10 vehicles a month with the new engines in conjunction with Japanese and British car-body manufacturers.
