A lot’s been made of the new Subaru BRZ and its naturally aspirated 2.4-liter four-cylinder boxer engine. The good news that came with the bigger engine — the first-gen BRZ was powered by a 2.0-liter four-cylinder boxer engine — was that it came with 23 more horsepower and 28 more pound-feet of torque. For power-starved fans of the BRZ, the new Subie’s output of 228 horsepower and 184 pound-feet of torque was a step in the right direction. Unfortunately, there is a caveat to the second-generation BRZ’s boxer engine. It’s still naturally aspirated, effectively squashing any and all dreams of seeing a turbocharged BRZ.

The Japanese automaker already explained that a turbocharged engine would come with a lot of complications, but for those who remain skeptical of Subie’s reasoning, this episode of Engineering Explained is must-see YouTube viewing. Host Jason Fenske is known for his deep dives on anything and everything related to automotive engineering. All the numbers might make your head spin as it did ours, but if you’re interested in understanding why the second-generation Subaru BRZ does not need a turbocharger, take some time out of your schedule and watch Fenske explain it in a way that we can (sort of) understand.
