Porsche 919

Just got back from holiday, not directly relevant to this design, but – on the plane I was reading the latest copy of GT Porsche.  It had an in-depth article on Porsche’s return to Le Mans this year with the new 919 Hybrid racer.  The car is unbelievably technical and clever, but I’m worried it’s not going to be shouty and fire-breathing enough.  Shallow aren’t I?
