Wait for an engine tune for the 2013. The M276 engine in the C300 is identical to the engine in the C350 for the 2013 MY (From the limited information I was able to find). C350 tunes are getting 330HP, So I would assume that if the engines are indeed the same, performance around that mark would be achievable by the C300.

There is quite a few vendors who do ECU tunes Kleemann, for example. Basically a reprogram of engine control software. It voids the warranty, but generally you can flash back to stock engine software if you ever need to bring your vehicle in for warranty work. Shouldn't have any adverse affects on the trans.

I'm in the same boat. I haven't driven in Sport, or past 4k RPM for that matter, but I know the power is there. Trying to baby it until I've hit 1000 km or so. I do like that fact that I will be able to achieve ~300HP in the future If I want to.

Unfortunately no, they began putting a detuned M276 engine in the C300 in 2013. Further still, I'm not certain if a tune will get MY 2013 C300's up to C350 power, It's just speculation I've heard, that the engines are mechanically the same. I do know that the C350 has bigger brakes, and a second air intake, but I believe in Canadian models, the only difference is the second air intake.

Jared, since my C350 had about 11,000 U.S. miles on it when I acquired it about three weeks ago, I didn't have to worry about break in. Let me assure you that when you are in S mode and you hammer the throttle, this thing will take off like a sailor in the wrong part of town, on shore leave, being chased by the Shore Patrol! You will be very pleased!
Various reviews I read on this engine/tranny combo in the C class report that, although the official factory 0-60mph time is 5.9 sec, some reviewers swear it's faster or actually measured quicker times.....I didn't save all the reports, but I know one guy got 5.7. The coupe is actually slightly heavier than the four door so it might be a tick slower. Anyway, the engine/tranny combo (7 spd auto) is superb in this car for my money.

From the 2013 C class brochure the dealer gave me, the C350 coupe has a curb weight of 3,693 lbs, and the C350 sedan's curb weight is 3,616. So, the coupe is 77 lbs heavier. That's not an enormous difference but there it is. Frankly I probably would have bought a coupe if I had found a 2012 C350 coupe, used, before I found my sedan.
I think the coupes are typically heavier because they need more beef in the structure for rigidity.
The heavyweight of the C class is the C300 4Matic, which is 3,726 lbs. That's 110 lbs heavier than the C350 sedan. I would think any handling advantage with all wheel drive would be somewhat offset by that extra weight, but maybe I'm splitting hairs.

I own a C300 4matic with the new 3.5L engine and would like to know where/when an ecu tune can be possible. Kleeman should start offering some tuning solutions to the new blueefficiency engines. I cant imagine how beastly the car would become with an ecu remap and a supercharger.

Yes I own the same vehicle, I contacted Eurocharged awhile ago about a tune, they said they would have more information in the coming months, but absolutely no information now.

My 2012 C350 is a Bluefficiency engine, too, so I will follow this topic with great interest.
Mercifully, my 2012 does not have the irritating, "save the planet" ECO-Stop feature. I wonder if the black box tuners can turn that bit off, for those of you who have it. (Yes, I'm aware there's a button on the dash to turn it off, but it defaults to on when you get back in the car again, because the Nanny state knows best. )
Maybe Eco-Stop has been gifted only to Americans, since we are told to feel guilty about everything. I could probably live with it, but I really don't like the concept.

I have the ECO feature, and it is not as bad as I thought. It only "turns on" when the engine is up to temperature, and major heating/air conditioning isn't being used. I can't even notice it happening, the engine is back on before I can move my foot from the brake to the gas. Even if you need power assist steering, the engine will light back up to assist in fractions of a second. I do question how much the constant on/off actually saves me in fuel, however.

Well, I sent them an email awhile ago about the C300... This is what they sent back. Maybe someone can translate for me, but it doesn't look too good.
Hello,
I was wondering if the Mercedes-Benz C300 is compatible with the tune for the M276 engine. I've heard that they share the same 3.5L direct injection V6, only separated by an ECU tune.
Thanks,
Jared

A C350 is a 3,5L a C300 is a 3,0L that's a very big difference!
