New Engines
The new E-Coupe comes with the new BlueEfficiency engine. Amongst other new technological breakthroughs, it has direct injection and stop-start function.
Although all good stuffs, are you concerned about the "newest" of this engine? Should I wait a year for the bugs to go ironed out?

E250 Cabriolet
What size is it? And, im not a fan of Start-Stop, got driven back from the Merc garage the other day in one, its incredibly quick response is good, but i like to hear the engine at all times. And I ABSOLUTELY hate hybrids, electric cars etc. Because you cant hear the engine when starting it up, or sometime when driving

2004 CLK320
Actually, in Canada the 2012 E-Coupes are not released yet. I went to their website and I could only "build" the 2011 models.
I learnt from the salesman that the 2012 E350 coupe will come with the new engine. With the gas prices now and since this will be my daily commute, I will get the smaller engine. According to the official mileage numbers, the new engine will give better mileage than my CLK320.
Going from a CLK320, the E350 with 302 HP will be great. I am also considering the C-Coupes but I am concerned about the potential bugs of a new engine.

2012 E350 Coupe
I don't know about the Canadian version, but the U.S. version of the new 302hp V6 does not have start-stop. MB had to modify the planned efficiency upgrades here due to poor fuel quality in the U.S.
It does have direct injection and other items designed to improve fuel efficiency.
This engine is sweet! It is extremely smooth and much more responsive compared to the previous 268hp V6. Some of that is also due to the upgraded 7g Plus trans. You feel nothing at idle. The car has the great quality of feeling "instantly ready to do what you want" most of the time in typical everyday driving ranges. My previous Benz did not feel that way. Never could be sure how it would react to requests for quick acceleration.
The only "negative" I can cite is that it does have an audible drone to it when accelerating. Maybe that was intentional for a sporty effect. Don't know and it's of no concern to me.
I also had a CLK320 prior to this car (2000 version). A great car, but this one has it beat by far. Bigger, heavier car and the drivetrain is much more powerful, yet I seem to be getting approx. the same fuel mileage as the old CLK and the new one is not even broken in yet. Only a little less than 1,000 miles.
There is always a concern with new technology, but I was willing to take that chance for the great performance and comparative efficiency. Also, this technology is not really new at all. It has been used on Euro delivered MB's for a few years now and seems to be doing fine there.

There aren't any issues I've heard of regarding the BE petrol engines anyway only the BE diesels - and the earliest ones at that, the A/C207 E-Class production was held back slightly in and amongst the problems with the diesel engines to make sure there were no issues.
The 350 CGI is a silky smooth engine as is the 7G+ 'box, would recommend if you have poor quality fuel to use some sort of cleaner/octane booster.
There's a quick shot of a C-Coupe I snapped the other day at my dealer.

I went to the dealership the other day and I saw all the new C-Coupes have the tag "BlueEfficency" on the front side panel. I googled and found this srart/stop feature. So, I thought this BE designation refer to direct-injection + start/stop.
Do the US models have this BE tag?

The start/stop feature has nothing to do with US fuel quality.
The difference between the euro M276 and US M276 is that the euro version uses stratified charge injection and has EGR, and the US version uses homogeneous charge injection and no EGR. This is due to the poor US fuel quality.
Both the S and CL AMG's have Eco start/stop, and within the next year or two expect other models to follow. MB had to due this with those cars right away to meet CAFE emissions requirements.

2012 E550 Coupe
I'm probably going to have one of the first production E550 coupes for 2012. I've been wondering about the brand new engine as well. I'm just hoping that MB did their homework on the new twin-turbo before putting it into production. I dunno...I trust them. If it was a GM engine, then I wouldn't touch it for a couple years!

It's interesting that my 302 D.I. seems to be virtually "shut off" at idle, even without start-stop. There is absolutely no sensation whatsoever that the engine is running (from inside the car) when paused at a red light, etc.
Do you think such smooth idling may be due to the absence of a balance shaft because of the 60 degree angle pistons? Or are there other considerations as well?

It looks really nice Ryan, got to say every time I see one I like them more and more. I'll take some more shots of it if it's still there in the next week; if you look in the picture there's a C63 in the background - going to look at that 
only problem is it has a very basic spec - which compared to a standard model W204 is high but I'd want extra kit on it (PPP, carbon etc)

Thanks for clarifying that. I did know that, but did a miserable job muddying the explanation.

2012 E350 Coupe
Almost bought a 2010 E350 coupe in April, 2010, then heard about the engine and trans. changes coming for 2012. Very glad I waited.
