Hi Guy's,
I just came back from the IAA in Frankfurt, Germany.
When I arrived, obviously the first thing I did was rush to the ///M zone on the BMW stand to check out the new BMW M5.
It's GREAT!!!, the car is put together so incredibly nice!!
Below is an explanation of the underhood of the F10 M5.
Here's an even more detailed explanation of the F10 M5 engine:

As luck would have it, I ran into a BMW buddy of mine I know from racing in Europe.
He showed me around the car, kicked some kids out of it so could finally get behind the wheel LOL! And he answered all the questions I had.
First of all the engine bay looks unfamiliar....You cant really see the engine block itself, its covered by two strange looking boxes in front of it and by inlets, tubes and the plastic ///M cover on top.
With all this stuff in front and on top of the engine it strikes me that the engine its self is set really far back and low in the engine bay.
Here are the questions and answers I asked my BMW friend:
Question: What is underneath the ///M cover?
My BMW guy did not want to take it off...for obvious reasons in the middle of the ///M stand with all these people around.
But after asking 5 times, he took it off, under one condition:
That I wouldn't take pictures....
The ///M cover covers two turbos that you can't see because of the heat shielding and some strange looking piping.
Question: What is this strange piping running 2 the turbos?
Question: What are the two strange looking boxes in front of the engine
Answer: These are the Air/Water Heat exchangers, cooling the compressed air coming from FROM the turbos on it's way to the cylinders.
Question: How does the airflow travel from the inlet to the cylinders
Traditionally the air is cooled by an intercooler before it reaches the turbo and enters the engine 'hot', this brilliant design by BMW get cool compressed air to the engine to maximize performance.
Further:
Love the Head up Display!!
I'm missing the carbon/plastic reinforced roof....Nothing a nice carbon look rap can't fix.
Don't like the black crossbars you can see through the front kidneys. I'm gonna spray paint the silver or gray.
