WardsAuto praised the Bolt EV's powertrain for its "abundant" torque and "thrilling" acceleration.
It happens to also achieve more than 230 miles of range on a single charge, which was unheard of at the time (the Model 3 was not out at that point).
The Pacifica Hybrid is one of just two returning entries on this year's list.
Wards called the plug-in hybrid system "a stroke of genius" when mated to this minivan.
Wards praised its vibration-free idle and a stop-start system that's "nearly imperceptible."
It's the first time in five years that a truck's gas engine made the list.
Due to an injection of new technology, some of which came from the GT350's 5.2-liter flat-crank V8, Ford's venerable Coyote is on this year's list.
Ford doesn't have a recent picture of its 5.0, so here's an example of what it can do in the right hands.
Wards gave the Civic Type R a spot on the list due to the engine's mix of economy and outright hustle.
This is Honda's 18th appearance on the 10 Best Engines list.
Wards gave props to the Clarity Fuel Cell's "Acura-level driving dynamics and delightfully silent operation."
There are still plenty of limits -- infrastructure, namely -- but the Clarity is still worthy of its spot on the list, even if you can't buy one yet.
Wards gave this 400-horsepower V6 a spot on the list because it's smooth as butter and puts down a buttload of power.
You wouldn't expect this unassuming luxury sedan could hustle, but it does.
Wards only tested the less-powerful variant of this engine, but it still made the list, thanks to its blend of efficiency and power. You hear that a lot on this list, don't you?
It doesn't help that the XF is quite the handsome car, and soon, there'll be a wagon variant available in the US!
Kia built a sports car that's actually very, very good, as is its engine. Of course it's on the list.
This is Kia's first time on the Wards list, and it definitely deserves it.
Wards gave the new Camry Hybrid a spot on the list after the car returned 40 mpg during "aggressive" driving.
Any car where you can drive like a jerk and get 40 mpg sounds pretty swell, indeed.
