Wards Auto's annual list of the top engines includes three electrified powertrains and one diesel for the 2016 model year.

The Wards 10 Best Engines list for 2016 also includes two naturally aspirated V-6s, a muscle-car V-8, a turbocharged/supercharged four cylinder, and a turbocharged inline six cylinder.

The 3.0L turbodiesel V-6 that powers the Ram 1500 EcoDiesel was again named to the list for the third year in a row. The 1500 EcoDiesel is the most fuel efficient large pickup with an EPA-rated fuel economy of 29 mpg on the highway. The engine is also available with the Jeep Grand Cherokee.

"The 3.0-liter from FCA was one of three diesels in pickup trucks we tested this year for Wards 10 Best Engines, and we expected a tough fight among them all," said Tom Murphy, executive editor of WardsAuto World. "But the Ram 1500 proved superior and continues to impress us with ideal measures of power, torque, refinement and luxury-car smoothness."

The list also included the 3.0L Turbocharged DOHC I-6 (BMW 340i); 3.6L DOHC V-6 (Chevrolet Camaro/Cadillac ATS); 1.5L DOHC 4-cyl./120-kW Drive Motor (Chevrolet Volt EREV); 5.2L DOHC V-8 (Ford Shelby GT350 Mustang); 2.0L DOHC 4-cyl./50-kW Drive Motor (Hyundai Sonata PHEV); 3.5L DOHC V-6 (Nissan Maxima); 2.0L Turbocharged DOHC 4-cyl. Boxer (Subaru WRX); 1.8L DOHC 4-cyl./53-kW Drive Motor (Toyota Prius HEV); and 2.0L Turbo/Supercharged DOHC 4-cyl. (Volvo XC90).
