In general, yes. But I wanted to point out technical aspects.

More will be said at NAIAS, and then featured on bmw-web.tv

nitty-gritty

Great pictures.
They have just changed the inlet an exhaust port.
the inlet is at the black box and the exhaust is in the middle.
because before the black box there is a intercooler.

The very short path from the exhaust ports to the turbos should help reduce lag.

OMG, those two exhaust manifolds are almost touching each other. I'm really interested how the cooling problem is solved.

I suppose enormous heat is developed right under the engine cover - which is made of plastic, btw. I just hope the plastic is heat-resistant.

These engine & engine bay must have hell of a cooling system to manage all that heat.



PS: now the "secret" of the engine in new 7er (from the spy pic) can be revealed: it's a twin-turbo 4.4L V8 with turbochargers and catalytic converters positioned in the V-section between the two rows of cylinders, and with a new configuration of the intake and exhaust ducts.

^^

i think that the turbos under the hood are cooler then the normal ones.
because the wind wil get in from the front from the car and will get out from the whipers.
I made a photo to explain it.

This could be 1 of the reasons why future BMWs will have massive grille's like those shown on Concept CS.

not really but of course, efficient aerodynamics ( airflow )
