Here are the 10 best engines in the world

On Monday, Wards Automotive released the latest edition of its annual list of best engines in the world. This is the 23rd time the publication has conducted the competition to find the best engine in the world. Eight of the 10 are new to the list for 2017, with two being holdovers from last year.

For 2017, the 10 winners offer a glimpse at the changing trends of modern automotive powertrains. There are four- and six-cylinder engines, along with several types of hybrid drive systems. Six of the 10 engines are turbocharged while another one is both turbocharged and supercharged. First the first time in the history of the competition, no eight-cylinder engines made the list.

"Automakers see downsizing, turbocharging, and electrification as key strategies for delivering no-compromise powertrains that also are fuel efficient, and this year's list clearly affirms that strategy," WardsAuto Senior Content Director Drew Winter said in the publication's post announcing the winners.

A total of 40 candidates were evaluated by the publication's editors in real-life, on-road driving conditions in October and November. Wards scored each engine based on horsepower, torque, comparative specs, noise attenuation, fuel economy, and application of new technology.

According to Wards, only new or significantly reengineered engines or electric propulsion systems that are available for sale in the US and are installed in cars having a base price of less than $62,000 are eligible for the top 10. In addition, the winners from the previous year are also eligible to defend their crowns. Last year, Wards banned VW Group products from consideration, as a result of the company's emissions scandal. This year, VW Group engines returned to the competition with the 2.0 liter powerplant from the Audi A4 and the new four-cylinder from Porsche's 718 sports car.
