As with past years, forced-induction reigns supreme, with seven of the ten engines featuring a turbo or supercharger. This year is slightly different, though, as two of the seven blown engines are turbocharged three-cylinder mills, from the Ford Fiesta and Mini Cooper. They're joined by the 2.0-liter turbo four from the Volvo S60, the 1.8-liter turbo four from the Volkswagen Jetta and the 2.0-liter boxer from the Subaru WRX.
BMW and Chrysler were the only marques to be named to this year's list twice, with the electric motor from the i3 joining the Mini's three-pot, and the 3.0-liter turbodiesel V6 in the Ram 1500 and Jeep Grand Cherokee repping the diesel crowd, alongside a certain supercharged monster. Hyundai also took a prize with a zero-emissions powertrain, with the Tucson FCV's 100-kilowatt fuel cell making the list (apparently Ward's is quite generous with what it deems an "engine").
Rounding out the list are two Autoblog favorites, each displacing 6.2 liters, but producing their power very differently. On the one hand, Chevrolet's overhead-valve, 455-horsepower V8, found in the Corvette, makes its power the old fashioned way. And in the other corner, we have one of the most exciting engines of the year – the 707-hp, 6.2-liter, supercharged Hellcat V8, featured so prominently in the Dodge Challenger and Charger SRT Hellcat.
"We spend a lot of time reading the powertrain tea leaves throughout the auto industry, and we're proud that this year's list is a microcosm of all the latest innovation coming from automakers," said Ward's Editor-in-Chief Drew Winter in a statement. "It's not just a list for enthusiasts or for environmentalists," he says.
"There's something for every vehicle shopper and every budget. All the powertrains on this list deliver a first-rate driving experience," Winter added.
