Siemens should have spent some of those billions of dollars on fuel pump R&D

Siemens reports another $5 billion phase of the project to start next year on how well the new fuel pumps will hold up with U.S. fuel blends

Great article! But this piqued my interest...

"BMW took the radical step of adopting a true dual-exhaust system for the N54 when launched in the 335i Coupe, the first time any 3-Series has employed such a layout. Engineers decided that because the turbocharger layout specified a small, low-inertia turbo driven by the exhaust from half the engine's cylinders, it was undesirable to attempt to combine such complicated hardware into a single-manifold design. Thus, each set of three cylinders exhausts through a turbocharger and a dedicated system running the length of the vehicle."

Does this mean that in the 335i Sedan, the exhaust is not a true dual exhaust?

it is a true dual system - each bank does not cross paths with the other. others vehicles with similar setups will collect all the exhaust from the headers thru collectors, and dump all the exhaust into a single turbo and exhaust (i.e. supra).

I wonder why BMW didnt give the new M3 direct injection? Anyone know or any speculations?
