Take that a step further, my S350 isn't badged Bluetec at all, only 4-matic on the boot, and blue efficiency on the front fender.

I don't entirely understand all I know about that process, but in kind of fits with the dicked up mess that has ensued since the engine displacement was no longer represented by the number on the boot. E300 used to be a 3.0L in the good ol days, today its just a penis sizing tool to confuse even the most nitnoid of us!
