Wards revealed its 2014 ten best engines winners and, interestingly, the list includes one electric motor, three engines fueled by diesel and various using turbocharging. Eight of the winning engines use direct fuel injection.

Tom Murphy of WardsAuto said this illustrates “the importance of fuel economy as automakers develop and market advanced new powertrains.”

WardsAuto revealed the list of winners in a lengthy December 12 post on their website.

This year’s winners are listed as follow:

  • 3.0L TFSI Supercharged DOHC V-6 (Audi S5)
  • 3.0L Turbodiesel DOHC I-6 (BMW 535d)
  • 3.0L Turbodiesel DOHC V-6 (Ram 1500 EcoDiesel)
  • 83 kilowatt Electric Motor (Fiat 500e)
  • 1.0L EcoBoost DOHC I-3 (Ford Fiesta)
  • 2.0L Turbodiesel DOHC I-4 (Chevrolet Cruze Diesel)
  • 6.2L OHV V-8 (Chevrolet Corvette Stingray)
  • 3.5L SOHC V-6 (Honda Accord)
  • 2.7L DOHC H-6 boxer (Porsche Cayman)
  • 1.8L Turbocharged DOHC I-4 (Volkswagen Jetta)

“The arrival of six advanced diesel engines in multiple vehicle segments shook up the competition as all six scored well in the evaluations,” wrote Murphy. “This is the first time more than two diesels have made the list in a single year. The biggest decline this year comes in 4-cyl. engines, as only two make the cut. Last year, there were five.”

Chrysler, with its Fiat 500e’s electric powertrain, is the only EV that made the list.

“We are very gratified with this year’s Chrysler Group selections because they demonstrate the depth of our engineering talent and shine a spotlight on the wide range of Chrysler Group products,” said Bob Lee, Chrysler Group Vice President and Head of Engine and Electrified Propulsion Engineering.

The all-electric system that powers the Fiat 500e A-segment hatchback was engineered from the ground up at Chrysler Group’s headquarters. This Michigan-based headquarter is home to global electrified propulsion development for Chrysler Group and its Italy-based alliance partner, Fiat S.p.A. Meanwhile, Chrysler Group engineers adapted the EcoDiesel for the NAFTA market following the engine’s debut in Europe.

Aside from the electric motor, the smallest engine on the list is Ford’s 1.0-liter EcoBoost, currently making its U.S. debut in the 2014 Ford Fiesta.
