10 of the World's best engines is an annual list of the ten "best" automobile engines available in the U.S. market, that are selected by Ward's AutoWorld magazine. The list was started in 1994 for Model Year 1995, and has been drawn every year since then, published at the end of the preceding year. For the 2020 competition, the name will be changed to Worlds 10 Best Engines and Propulsion Systems.
