V12s are on the way out for AMG, a 700hp turbo V8 has been rumored the replacement for quite some time. V12 will remain in 600 and Maybach cars so they say.

I wonder what are they going to do with the V12, Mercedes has always lead on this niche, and now BMW is going to have the best V12 engine in history, the most efficient. The 600 engine is a dinossaur.

I doubt Mercedes will be completely phasing out their V12 engine. It just doesn't seem right letting the competition have one. My best guess is that this was a PR move that seemed appropriate at the time it was released.

The sale of Mercedes cars with V12 engines is so minor that it really makes no difference what these engines do to the environment. In my opinion they can afford to keep a V12 in the lineup. All they need to do is focus on making it more efficient. That's the top priority. This can be done with modernizing the engine and of course trying to minimize the weight of the vehicle as well as some transmission gear ratio modification.

A 700hp bi-turbo V8 would make up for the loss of the extra four cylinders. Potency seems not to be lacking, and this type of engine has exceptional smoothness as judged on feedback to current BMW engines.
A 700hp TT V8 with DI and 8sp MCT and KERS would sound way to good. The next top-line SL would be a killer with a lower curb weight (close to today's US spec Black Series or 4.200 lbs)

This should be 5,5-liter BiTurbo V8.

Don't worry, Mercedes will not allow BMW to upstage them in the engine stakes. They will have a V12 engine as long as the Bavarians have theirs. We have not seen the last of the great Mercedes V12.

Well, it may well be true we will still see a V12 on the ranks of MB, but it may be an "update" of the current one. Kind of how the same 5-speed transmission made it this long, only in the top spec models. While the current V12 is fine, it would still remain wanting, if only from an enthusiast's perspective, for 4-valve and other tech goodies of the downline engines.

I think Mercedes will continue to make a V12 for their top of the line SL, S, and CL models only because of the luxury refinement and the prestige. I don't expect AMG to consider tinkering with it because they've somewhat altered their ways in takling performance cars these days by citing more performance oriented cars with higher efficiency. So it seems like a smaller displacement and lighter V8 is the way to go...For now.

Right. V12s will remain in the 600 cars and maybe the Maybachs, but AMG will go lighter with super-potent V8s.

The supercars insider of carspyshots, McLaren P10, says that 4.6 engine will have 476 hp, and is due to replace the AMG engines in C-Class and SLK range, the one that will replace the AMG engines in the E-Class and the rest of cars that use the 63 AMG is a 5.0 V8 Biturbo, with aparently 600 hp (or even more, because McLaren tells it will be between 570 and 700 hp).

Then it´s the top range AMGs with the 700 hp V8 engine having the KERS on them. Also, he says that the 500 engine wont have twin turbo, so it should be a CGI engine, it will be a smaller engine that todays one (so 4.6 sounds very possible) and will have a similar power than the one Toni says.

The V6 engines won´t stay with us so much time more, because on the next CLS will debute the new one (I expect them to compete with the 3.0 TT that BMW uses on the 740i).

Promising times for Mercedes engines.
