Wards releases it's annual 10 best engines list, and while most are not as sexy as the sheetmetal that surrounds them, we should point out that engines often represent 30 percent or more of the cost of new vehicles.

Wards 10 Best Engines awards

Twenty-two years and counting

The 2016 list from Wards marks the 21st year of the magazine's 10 Best Engines list. Not only is this the only award of its kind in North American it is, Wards once pointed out, "considered by many to be the ‘Oscars' for automotive engines," an opinion we prefer to let slide.

This year, the list of 31 ten best nominees included all of last year's 10 winners, with the exception of Volkswagen. The company was also barred from this year's competition due to the fallout from its diesel emissions scandal. Like 2014 only two previous winners returned to the list from 2015, one from Fiat Chrysler and the other from Subaru.

In order to qualify, each engine must be available in a regular-production U.S.-specification model scheduled to be on-sale no later than the end of the first quarter of 2015. Vehicles the engines are available in must have a base price of no more than $61,000 (last year's cap was $60,000).
