I for one am disappointed they've ditched the SBC. They should've at least tried to fix/improve it instead of ditching it. Yes it was problematic, but that's the case with all new technology. You learn from your mistakes and try your best to iron out all bugs, not just give up.

Knowing MB, I know they've got something up their sleeves to replace it, otherwise it's a step backward for Mercedes-Benz.

The oval exhausts are for the 350's and the rectangular are the 550's.
