1. Subaru BRZ 2.0L Flat-Four
Lastly – and keep in mind this list is in no particular order – is the 2.0-liter flat-four engine powering the Subaru BRZ, Scion FR-S, and Toyota GT86. The vehicle that has garnered more than enough attention since its release now has another accolade to go along with it. Though the vehicle was jointly developed between both automakers, Subaru gets credit for the engine despite Toyota aiding in the unique fuel system that powers it. Some have complained that on paper, the 2.0-liter with 200 hp is underpowered for a sports car like the BRZ, but those that have gotten behind the wheel realize why it succeeds in the car.
