Guys,,, whats the highest speed u have recorded till now with your W204 C280 or C300 ( I have heard it cant pass the 245 km/h )

P.S: I wont even dara and cross the 220,,, but i wana know its capabilities !

Yes the last generation w203 C280 had the same engine as the w204 C300. Its identification is M272, a 3.0 liter 228 horse power v6. As for top speed, in the United States it's governor limited to 130 mph.

Drivetrains are the same. As noted above, in the NA market, speed is governed at 130 mph [210 kph] because pf the use of H-rated tires in our market on the C300 [aka C280 everywhere else in the world].

So... if its the same engine i could put W203 engine mods into a W204? Or is there something that i just dont understand about the whole "same engine"?

I believe the OP was referring to the W204 C280, not the W203. I believe the W203 C230 has the same engine as this model's C300, but not sure about this model's C280 since it is only available overseas (meaning not in NA).

Which means I'm definately not sure when the governor kicks in for that model.

I can't completely follow the post above, but the most recent W203s ['07 model year] and W204s indeed have the same V6 drivetrains [engine / trans combination]. And notwithstanding the insistence on fooling with the badging in different markets, the 2.5 and 3.0 and 3.5 versions of the current V6 do not vary significantly around the world - there are detail differences due to emission regulations, but last year's USA C280 and this year's C300 and this year's EU C280 all have the same engines. Don't be confused by the badging - a visit to the German MB website should clear up the confusion - the specs are there for all to see.

I long for the time when the marketing people didn't have the power to mess with the naming and badging conventions the way they do now.

Speed governing is another issue - that varies by market and the choice of tires and regulations in each market - it's easy to do with the engine computer, so there can be an almost infinite number of variations at little cost to DBAG.

Yes,,, U r right same engines.. C280 = C300 except for the emissions. Egypt follows Germany & europe i think... USA cars are a bit different due to certain regulations.

However,, it is claimed to have the same acceleration to 100 km/h (7.2s) however,, in Egypt they claim a topspeed of 250 km/h though Germany claims only 244!

On the mods for the c300 w204, I had the same idea that since the engine was the same the mods should be simple, if not direct swap-overs from the w203. But no one here seemed to know the answer. So I got to thinking that while the same engine, lots of other stuff has changed. First, the 4matic is supposed to be the new generation. And I think the 7 speed auto is new as well to the c-class. These may not affect the engine, but may affect how the engine applies it power, engine mapping, etc. These I rate as minor. Next up, the intake is supposed to new - an AMG intake system of sorts. So, anything pre-engine block will have changed. This may be moderate for intake mods, etc. Also, with emissions always getting tighter, I suspect the engine mapping may be different, or the o2 sensor(s)/egr valves (if present) may have been tweaked/relocated, resulting in a different smog system. If true, this would impact engine modding to still work within the smog system. Again, moderate impact. Finally, much aftermarket engine modding would be in the exhaust end of things, in terms of the header, cat(s) and exhaust itself. Since this is physically a new car, the whole exhuast itself is not likely a swap-over fromt the w203 due to changes in flex pipe, mounting locations, physical dimensions, etc. Also, they have changed the location of the cat(s) (not sure if car has one or two). And the header at the engine has likely changed dimensions to reflect new engine-bay design. All of these may be minor changes from a manufactiruing point of view, but are major in terms of using w203 parts (not likely to bolt-up with any amount of finesse). In the end I figured its the same engine, sure, but little things would be different enough to prevent a direct swap-over from the w203. With that said, why the tuners are taking so long to port the w203 stuff over into the w204 platform is beyond me, but maybe they need a long testing/break-in/real world experience phase?

Why won't you cross 220? don't feel save in your merc'? Oh just saw you are from egypt!

but still hittin' 220 ha??

Highways here r a shame... very often you find a truck coming outta nowhere crossing the highway while u r cruising with ur fancy merc .... believe me,,, u have to have real guts to cross the 150 in here... otherwise,,, u will end up under one of those big footers !!

To the extent that the question is about engine mods, I pass....you need expert help from a factory mechanic to tell you what you want to know.

Both the engine and the transmissiion [yes, the 7-spd] first appeared on the 2006 W203 in our market, and have been carried over without major changes. I came very close to buying an '06 C280 just to get this drivetrain, but in the end, decided to wait for the W204....and glad I did. But I certainly wouldn't recommend buying "modding" parts for the W204 without some expert advice...the details under the covers and under the car could indeed be deal-breakers, depending on what you want to do.

I know what twinspark is talking about.. I'm in Egypt too. not only the cross traffic is a problem but the actual roads. We're talking roller coster rides here. Yalla Twinspark, i'm joining the w204 club this week!

Waiting for you Mr. Rollercoaster

Yalla Yalla, Kaifa Haluk!!!!

any one use w-203 parts on there w-204 yet?

and yes holy dead revival batman..
