The problem is that the E320 CDI (diesel), is faster, cheaper and more
economical than the petrol E320. Which means in Europe sales of the E320 are
This is what killed off the S320 and it was replaced with the S350 in order
to offer a product superior to the S320 CDI.
Merc diesels are getting too good for their own good. And it is amusing
their refusal to export the V8 diesels.
Yes, but if you really want a diesel V8, there is one in the Audi A8,
although it isn't quite flashy enough for British tastes, the A8 does better
in Germany where people are less keen to flash their cash.
Also there is the diesel V10 in the new VW Phaeton.
So Merc had better start offering its V8 diesel to us soon!
Apparently there are AMG variants of diesels too now!
Going on technical merits & ignoring the effects of any tax disincentives
on diesel cars, i'll certainly prefer the diesel version of the E 320 or S 320
to the inferior petrol version !
I don't seem too impressed with the so-called S 350 petrol model
as it's a 3.7 litre & performance expectations etc. to be seen in the context
of a 3.7 litre engine. Also, in all consistency they ought to label it as S 370
instead to reduce confusion !
Anycase, i'll still prefer the (diesel of course !) S 400 over the 'S 350' or
more appropriately what which should be known as S 370, unless they reduce the
engine size to 3.5 litres in order for the S 350 label to have its real meaning
With few exceptions, their diesel models are nowadays the better models over
their petrol models ! Especially in fuel efficientcy, economy, torque
performance & possibly even (non-idling i.e. crusing or accelerating) noise
levels in that it's quieter !! Exhaust particulate emissions are relatively
insignificant minor 'irritants' with the latest diesel cDi charge-cooled
technologies. Therfore overall, the prefered choice remains diesel over
petrol or electric or fuel-cell etc. least for the time being.

Yes. They are a problem. The issue has split the world.
Japan is very anti-diesel, all diesels in cities must be scrapped after 7
Europe is very pro-diesel, looking at the fuel economy and CO2 benefits,
while other emmisions are rapidly being brought under control.
Meanwhile the USA just doesn't care :)
Aside from fuel costs there's a good reason for US consumers shunning
diesels. The USA had a flirt with diesels 25 years ago, which began with VWs
introduction of the Rabbit (Golf 1) diesel in 1977, a conversion of their
standard gasoline inline 4 cylinder. Money-see-monkey-do GM followed shortly
thereafter with their own range of hastily converted, poorly engineered
Aside from poor performance, these proved to be hopelessly unreliable, to
the point where GM was replacing engines at a rate of nearly 50% of
production at one point (Rumor from GM service types was that the other 50%
just went off into the woods & died!) GM faced massive consumer litigation
and thus would pop for free replacement engines on theses vehicles at
ridiculously high mileage. Hundreds of thousands of consumers bought these
bogus products in good faith and not only never bought another diesel, many
dumped GM forever, leaving the door wide open for the Japanese to conquest
As for VWs cool little diesel, while the initial (77-79) run of these cars
was in hot demand, by 1980 fuel supply fears eased in the US and VW diesel
sales cooled. VW then had big problems with internal block casting cracks on
the 80 and later models which filled the cooling systems with oil. Other
problems arose with the fuel system, premature ring failure due to high
sulphur fuels in some parts of the US (usually people running across the
border into Mexico to by $.15 /gal. fuel.), broken crankshafts, etc.To VWs
credit these problems were addressed rather quickly, and turbo versions were
introduced that mitigated performance complaints, albeit at the risk of even
more reliability problems. This actually triggered VWs sad 15+ year slide
into oblivion here in the USA, which didn't turn around until the
introduction of the New Beetle in the late '90's. Many a former VW devote
ran to Honda, Toyota, etc. and has never returned.
As far as i'm concerned, i consider that both petrol & diesel each have their
different types of pollutants or 'toxins' etc. & there's no clear cut objective
determinant as to which is overall the more 'unhealthy' fuel to use !!
Therefore, i prefer to regard petrol & diesel as on the same level of
preference, to say the least, with their different pros & cons considered.
But i'll still utimately prefer a (modern cDi charge-cooled, not a primitive !)
diesel over even the latest Kompressor or turbo petrol engines etc. as from
the area of specific fuel efficientcy, fuel economy, long driving range &
good torque performance (which i prefer over 'high' power outputs as
i find high torque more practically useful than high power in a stop-start
driving envirnoment etc.) the latest M-B diesels especially do appear
as superior alternatives to theirs or for that matter, almost any other
petrol engines around !
Even IF the 'toxicity' of pollutant discharge from a diesel vehicle is more
than a petrol model, due to the far superior fuel efficientcy in a diesel,
less volume / weight of diesel would be used to generate the same level
of output performance compared to a petrol model i.e. the petrol engine
would have to burn up more weight / volume of petrol fuel to match the
same performance output as the diesel model, thereby that can effectively
'negate' any advantages of perceived lower levels of 'toxicity' with petrol !
I find the Japanese diesel vehicles especially their cars & vans inferior
in performance, noise vibration harshness levels compared to European
diesel vans & cars. Nothing outstanding about Japanese diesel vehicle
emission levels as well. So if the Japanese are 'anti-diesel', due to the
lousiness of their own diesel vehicles, that's then no surprise to me !
The Europeans are very much into further improvements in diesel technology
compared to others so it's nothing surprising if they end up making the best
diesels around that can remove much of the 'anti-diesel' sentiment around
which tends to be based on inferior & outdated diesel technology, as that's
about all the rest of the world knows when it comes to diesels !
I find USA diesels 'so-so' in appeal so that can explain their 'lacklustre'
interest in diesel cars & vans especially. I figure they need to try out the
modern European diesel models much more to fire up greater interest in
preference for diesel models !

In the UK diesel fuel costs the same as petrol, yet diesel-car sales are
rising. It's not just the lower fuel costs that drive this, though I don't
doubt it's a factor, perhaps especially with fleet operators.
