Boxer Rally spec Z - How did we get here?

There are two things that Subaru has told us the BRZ will never get from the day that the design was revealed.1. It will never get a turbocharged engine2. It will never be All Wheel DriveBut now they have built the Boxer Rally spec.Z which is both.How did we get to this point?When we thought that this AWD BRZ Rally Car was just going to be a clone of the Toyota Celica that we have seen testing for the 2027 WRC season, it seemed like this was at least going to be part of Subaru's return to the WRC. But it seemed like it was going to be using Toyota's engine and drivetrain.Now we know that the Boxer Rally spec.Z is at least using a Subaru engine (A turbocharged BRZ FA24 from the looks of it), but that also makes it seem like this may not have nearly as much to do with a return to the WRC as we thought.So why is Subaru building this car? What are they testing and what do they hope to learn?After going through a number of videos from the launch of the car, I have a couple of guesses.Thanks for watching and Stay Tuned!
