Why doesn't Mercedes-Benz use straight six engines?

What advantage is there to wafting by using an I6?

From doing all the maths calcs at uni (engineering course) about piston balancing and imaninary cranks etc etc (its some tricky ****), an I6 is the best balancing you can get from an engine.

iirc the primary (real) crank and secondary crank (imaginary) cannot both balance - The vector diagrams do not close on the MR (mass radius) or MRD (mass radius diameter) diagrams. Howeber the I6 is the closest to perfect you can balance.

Whether this is of any help I don't know:p

Because in reality it doesnt make any difference, and V6's are a smaller package enabling them to fit into less space, less engine bay space means more cabin space.

Or at least thats the official version, in reality its probably to do with manufacturing costs or something.
 
Surely the main disadvantage of a I6 compared to a V6 is its length, so most cars tend to go the way of a V? That's my understanding of it anyway :p
 
they used to
iirc all the diesels in the old E were Inline; I4, I5 and the 3.0 and 3.2 were I6

the first W210 E280 and E320 were also I6s, before they were replaced with V6s, probably in the W211 facelift.

all the engines in the new E are either I4s or V6s..
 
1JZ and 2JZ engines are legendary in their capability, I thought every knew that. They are used in loads of cars across the Toyota/Lexus range. You'd be wise not to try and catch me out on technicalities of Japanese cars ;)
