TOKYO, May 28 (Reuters) - Toyota Motor and smaller Japanese automakers Subaru and Mazda Motor have each committed to developing new engines tailored to electrification, they said in a joint statement on Tuesday.

"With these engines, each of the three companies will aim to optimize integration with motors, batteries, and other electric drive units," they said in the statement, pledging to make more compact engines that will allow for lower hoods. (Reporting by Daniel Leussink; Editing by Jamie Freed)
