The 10 Best Engines In The World

Ward's Automotive just released its annual list of the world's 10 best engines - and it's the most diverse selection of powerplants in the 21-year history of the award.

Six of the ten engines on the list use turbocharging technology to boost horsepower, while another uses supercharging to create ridiculous amounts of power.

There's only one naturally aspirated internal combustion engine, one fuel cell, and one electric motor on this year's list. Of the 10 best engines,four are holdovers from last year's list, while six others make their debut.

According to Ward's, only new or significantly re-engineered engines or propulsion systems that are available for sale in the U.S. and are installed in cars having a base price of less than $60,000 are eligible for the top 10 list.

A total of 37 entries - 10 returning winners from last year and 27 new contenders - were evaluated by Ward's team of eight editors. All of the cars were put through their paces under normal daily commutes by the editors over the past two months in Detroit. Ward's Auto editors then scored each engine based on power, torque, technology, fuel economy, and relative competitiveness, while taking noise, vibrations, and refinement into account
