I guess I'm late to realize this, but it just occurred to me that Mercedes
no longer has a straight six. I guess it ended with the 124 cars. What is
the reason for this switch? Is it a good thing or a bad thing?
Will the v's run forever as the Benz straight 4 & 6's always have? My
inkling would be yes, as the v-8's they made in the 70's & 80's were some of
the best engines ever built (excluding the 380). But I've always loved the
power delivery from a straight six. From the 1967 230 I had until a few
years ago, to the 1986 300e I have now.
It seems to me Benz should always make a straight six....
Reason is production cost: V6, V8 and V12 can be
produced on the very same production line.
Another aspect is the shorter length, allowing
shorter hoods resp. more crumple space in crashes.
Juergen - loved his 1972 230 6-banger straight
Merc still make a straight six turbo diesel 3.2 litre and its available in
the the new e320cdi and s320cdi. Before you scoff these engines produce as
much torque as the larger v8s. unfortunately they are not available in all
US states for emission reasons.
The 3,2-litre straight six diesel returns to USA this autumn as 2004
E320 CDI. If it is selling well, we might see E320 CDI estate as well as
possibly 4-litre V8 diesel motor.
You are correct in a part about the emission reasons. California is not
too kind to the diesel motors because of NOX output. The cleaner fuel
mandate in 2006 will perhaps change the perception of diesel motors.

The V-6 were introduced in the second year of the W210. The first
year had the straight six.
The reason, like Juergen says, was cost, even though a 90 degree V-6
is not the best for balance (a 60 degree V6 is better balanced). But
because a 90 V8 is better, Mercedes just used the same 90 block.
This matches the remarks made by german motor journalist.
The swap from inline to V-six was made by Mercedes out of the following
* lighter and shorter engine, helps to save space and fuel
* Many parts are interchangeable between V6 and V8, so they have advantages
at the engine assembly line
IMHO Mercedes gave away a big advantage to BMW, who ever refused to make a
V6 engine and brag around with their smooth inline sixes (they are really

Agreed, the switch from Straight 6 to V6 was (IMHO) a bad move from
And I think one of the reasons was that the C-class needed a 6 cylinder
engine, and the "old" inline just wouldnt fit.
Nowadays if you want a real six you have to go BMW.
And a V6 is so damn _Audi_............
I think I agree. Stright sixes just have a better power delivery. And agreed
on the bmw comment as well... I used to have a '91 735 that was smooth as
I think benz has made a mistake....Hopefully they'll at least bring the
diesels back to the US....
Actually it's more like so damn _Alfa_ ;-) Which, I hasten to add, isn't
a bad thing necessarily. The howl of my GTV6's V6 still tingles my spine.
Actually Lancia produced the world's first V6, but they're the under the
same group of comanies today, so I used poetic license...
