When it's time to put pen to paper (or fingers to keyboard) and use the word "engine-powered," it can be helpful to remember that there are other ways to describe a power source. Some synonyms to consider include machine-operated, motor-driven, mechanically-fueled, or mechanical-energy-driven. These alternatives can make your writing sound fresher and more varied. For example, instead of saying "The car was engine-powered," try "The car was mechanically-fueled." Using different words can help engage the reader and keep their attention. So next time you need to describe a machine with an engine, think outside of the box and try reaching for one of these alternative phrases.
