Quote from MB USA website:

New-generation 3.5L Direct Injection V-6 engine
A new 248-hp 3.5-liter V-6 combines numerous advances to deliver more torque over a wider range of rpm. Its rapid-multispark ignition fires up to four times per millisecond, while new high-pressure Direct Injection microscopically tunes the fuel spray, reducing emissions, fuel consumption and noise. A lightweight diecast-alloy block, quicker and more widely variable valve timing, reduced friction, and clever "on-demand" ancillary components like the alternator further boost efficiency.

And only gets 20/27 MPG.

Is this true?

That looks like the detuned version of the DI 3.5 replacing the 3-liter for the 4-matic cars. Every word after "V-6" can be ignored as nothing new.

Yep that's it. The 3.5L in the C350 will remain at 302HP.

for some reason....looking at those numbers makes me sad as I'm planning on a C350 coupe for my next car. 3.5L and only 248hp? maybe ill go with the BMW 335i coupe.

Read again... the C350 will remain 302HP. The C300 is 248.

there has to be something you can do to get the 300's 3.5 to produce the same as the 350's 3.5, I'm sure an ECU tune is involved and perhaps some more mods.

MDMercedesGuy

There are a couple of other threads on here talking about this. I want to say that someone found that the differences were not insignificant (cams, etc).

the C350 coupe will have 300+ hp, so you should be good
