The channel itself has a number of other videos released at the same time for the BRZ. This includes the safety/crash testing, further interviews with the people involved with its development, modelling showing the working parts in action etc.
I have to say Subaru know how to market this, and provide an outlet for nerds seeking every bit of information on what really went on in their heads/considerations/challenges when making the BRZ. Can't help but feel the infection of their enthusiasm, but at the same time some sadness knowing they believe (and I agree) this is the best and last of it's kind for ICE sports cars.
