what does the car have a divorced wastegate right behind the side window. i am under the impression that this car has an n/a engine, and wastegates are used to remove excess boost pressure that is caused by a turbocharger. so someone please explain what that is, or what's is function. secondly, why are the exhaust placed in the center of the back. how is this more efficient? i believe that teh pagani zonda c-12 S uses this as well. i was wondering why more cars dont use this type of design and in what way (technical explanation) of why it is better.
