Can you believe we’re living in a day and age where U.S. customers of the 86 prefer the automatic transmission over the short-throw manual? Even though these people don’t get that the torque-converter automatic makes the boxer-engined sports car worse, there’s still hope going forward with the Gen 2.
Subaru is understood to prepare a concept previewing the second generation of the BRZ for the 2019 Tokyo Motor Show in October, then the real deal would follow in the first half of 2021. A report from a Japanese publication is certain that “a new platform” is in the cards, and Toyota is also involved in the project.

“The engine will be changed from the horizontally-opposed FA20 to the FA24” according to Best Car, thus improving the output to 220 PS and 24.5 kg-m. That’s 217 horsepower and 240 Nm of torque, translating to 177 pound-feet. The current generation with the 2.0-liter boxer is rated at 205 horsepower and 156 pound-feet (212 Nm), an upgrade dating back to 2016 for the 2017 model year.

But here’s the thing. The FA24 mentioned by Best Car is a 2.4-liter boxer introduced in 2018 with the 2019 Subaru Ascent mid-size crossover. In this application, the FA24F combines direct injection with turbocharging for an output of 264 PS (260 horsepower) and 277 pound-feet (376 Nm) of torque.

There’s no N/A version of the FA24 so far, but knowing Subaru, it should be easy for them to make the switch from forced induction to natural aspiration. This change also implies hotter cams and a variety of other modifications meant to make the engine more rev-happy, potent, but also reliable for sporty driving.

The FA20D in the BRZ and 86 utilizes D-4S injection from Toyota and AVCS variable valve timing from Subaru, a combination that requires 0W-20 low-friction oil. Even though that sounds exotic, it’s worthy of highlighting that even regular cars such as the Honda Civic and Accord run on 0W-20 motor oil.

As we wait for Subaru and Toyota to reveal more information about the Gen 2 boxer brothers, don’t forget this isn’t the first time we’ve heard about the upgrade from 2.0 to 2.4 liters. The Japan Times reported such as possibility in April 2018, and production is expected to be handled by the Gunma plant in Japan.
