NEW V6 & V8 CDI and V6 Engines

V6 CDI and V6 fuel engines will be available with the 7G-Tronic:

C 280 CDI with 190 HP and 3.0 liters of V6-CDI (OM642) approx.. February/March 05
C 320 CDI with 231 HP and 3.0 liters of V6-CDI (OM642) ca. February/March 05

C 230, 2.3 liters of V6 M272 with 204 HP starting from June 2005
C 280, 2.8 liters of V6 M272 with 231 HP starting from June 2005
C 350, 3.5 liters of V6 M272 with 272 HP starting from June 2005

E 350, 3.5 liters of V6 M272 with 272 HP starting from December 2004
E 280 CDI with 190 HP of 3.0 liters of V6-CDI (OM642) approx. June 2005
E 320 CDI with 231 HP of 3.0 liters of V6-CDI (OM642) approx. June 2005
E 280 V6 M272 with 231 HP of 2.8 liters of June 2005
E 400 CDI V8 OM629 with 300 HP off approx. September 2005
E 320 CDI 4matic V6-CDI of 3.0 liters of 231 HP off approx. September 2005

Both CDI's 280 CDI and 320 CDI will come beside C and e-class also into the CLK as well as into the new m-class.
The s-class and the CLS get only the large 320 CDI.
Current CDI of models like 270 CDI and 400 CDI those not yet the European Union 4 fulfills, can until January 06 be further-built. Only new models must fulfill 05 European Union 4 starting from January. Thus takes place the conversion new 400 CDI in September 05 and 280 CDI for 270 CDI still in time.

Welcome to approx 4 hours ago.

great info!! Will the C230, C280, and E280 be coming to the states? I'm taking it the 280 would replace the 2.6 liter V6 in the C240, and the C230 replace the supercharged I-4 in the C230 kompressor?

dewuser

Here is what is known:

CURRENT V6
2.6L 18 - valve V6 - 168 hp
3.2L 18 - valve V6 - 215 hp

NEW V6
3.5L 24 – valve V6 - 268 hp (currently available on the SLK350)
2.3L ?? – valve V6 - 204 hp
2.8L ?? – valve V6 - 231 hp

Here is where we need more info:
How many valves for the 2.3L and 2.8L engines?

So theoretically the following could happen:

2.3 V6 replaces the 1.8L I4

2.8 V6 replaces the 2.6L V6

3.5 V6 replaces the 3.2L V6

akbro93704

Given that the 2.3 and 2.8 have a high amount of horsepower per liter, the 2.3 and 2.8 would mostly likely be 24-valve DOHC as well, just smaller versions of the new 3.5 with the same high tech design...
PS- I think this 2.3 liter V6 has just become the smallest V6 car engine ever built,lol

Does that mean that all the M272 V6 engines will have the same new technology, just different bore sizes -- 2.3L, 2.8L and 3.5L?

akbro93704

ya im pretty sure, i just posted that lol

dewuser

It may be that the B-CLASS will get the 1.8L I4 to be cost effective!
Well at this point, it’s all speculations!

prodigy1387

so BMW's 2.3 liter I-6 in the 323i is the smallest I-6 ever built then?

anal

I'm wondering if this new family of 4 valve V6s will even physically fit in the engine bay of a W203...the current 2.6/3.2 is already huge (width-wise) and a 4 cam/4 valve based on this engine will be even wider...

CHATMANR

The Mazda MX-3, 1992 - 1996 had the smallest production V6 [1.8l] almost 10 years ago. The V6 available in the top-of-the-line MX-3 was unusual for two major reasons. First, it made the MX-3 the first vehicle in its class to offer a V6 engine. And second, the 1.8-litre was at the time the smallest displacement V6 in mass production.

[180]

Maybe the new 2.8 Liter engine will replace the 3.2?

The old W202 line up used to be:
C180
C200
C220 (Later replaced by C230, then C230K)
C280
C36 (Later replaced by C43)

And it evolved into W203:
C180K
C200K
C230K
C240
C320
C32K (Replaced by C55)

Maybe with the new generation, the 2.8 will be at the top of the non-AMG C-Classes, and at the bottom of the E-Class.

prodigy1387

that is possible, but i'm not so sure they'd do that for marketing reasons. the c32 was replaced by the c55 only because all of the competition were offering v-8's in their supercars, so MB had to keep up. BMW is going to have a larger displacement v-6 in it's new 3 series, so i'm not sure sure if MB would go down to a 2.8. i think the 3.5 is most likely going to be the top end C-class.

EDIT: I-6 in the BMW, not v-6 sorry.

Jon200

I am sure they will, Benz engineers are smart and they wouldn't have made the engine if they couldn't be fitted into the C class.

Personally, I am looking forward to the new range of V6s, valve timingm variable induction length, DOHC...etc etc , great marketing boost for Benz to the very least

mctwin2kman

Also to add if they are not 90 degree V-6's they will actually be smaller width wise than the curent ones. A 60 degree six with 24 valves should fit just fine in there.

trench

If Mercedes holds to past trends the bore size will probably be the same - they'll shorten the stoke to reduce displacement.

Saprissa

I can already see it !! a 350 to replace my 320 engine... and then add a pulley kit, and then supercharge it, and then....

dewuser

Trench - Thanks for correcting me and I agree! MB will shorten the stroke and you know what that means... Higher RPMs.
I would not mind a High revving V6 on a C-Class

Saprissa - The 3.5L will certainly replace the 3.2L. Just like the:
SLK320 was replaced by the SLK350
SLK32 was replaced by the SLK55

davis449

If those facts are correct, it's good to see they're gonna bring back the 2.8 w/ more horsepower and replace the wimpy 2.4 in the C 240 (no offense to those in here who drive a C 240, this is just one man's opinion).

AndrewK

BTW prodigy, the 323i had a 2.5 liter 170 hp engine. It was badged 323i to make it seem like there was more seperation between the 323 (actually 325) and the 328. Even the Z3 was badged Z3 2.3 despite being a 2.5! Gotta love the marketing guys...

amdeutsch

The C240 has a 2.6.

pookie

wow. glad to see diesel coming to the US in a C. then probably wouldn't have to make so many trips to the gas station (of course, this is assuming that if i had my car and actually driving it around)

marc32

Well, I'm not too sure if they will even bring in a diesel in the c class.

It would be nice to see a diesel in all model ranges in mercedes line up here in the states. I wonder if anyone can clarify that.

dewuser

I don’t know about the DIESEL Mercedes Benz coming to the US in masses, because according to the new CALIFORNIA emissions law you can’t even sell a new DIESEL vehicle, unless it’s used.
Well since CALIFORNIA accounts for a great percentage of Mercedes Benz sales in US, I wouldn’t count on them bringing DIESEL powered cars
