Future high-performance models from Mercedes-Benz will not have more than eight cylinders, if recent rumors out of Germany are to be believed. The company will apparently ditch its V12 motors in favor of smaller, more efficient turbocharged V8s.
The move mirrors BMW’s recent decision to drop its naturally aspirated V10 in favor of a twin-turbo V8. According to Germany’s Autobild, Mercedes has already begun developing future models without sufficient space for a V12, so the decision is seemingly long-term and permanent.
Models currently featuring the company’s 6.0-liter V12 include the S600, CL600, SL600, S65, CL65, and SL65.
The rumors seem to echo a report from April about AMG’s future engine offerings. The U.K.’s Car magazine reported the performance division’s 6.2-liter V8 would be replaced by a twin-turbo 5.0-liter V8. It went on to say the 6.0-liter V12 would be replaced by an even more powerful version of the turbo V8, possibly with as much as 700 horsepower.
The report indicated Mercedes might also be working on non-AMG V8s, including a 355 horsepower 4.0-liter, a 435 horsepower 4.6-liter, and a 544 horsepower 5.5-liter.
All of this can be viewed as a stepping stone to even more efficient technologies. AMG is rumored to be working on a plug-in hybrid powertrain that will hit the market in 2012. A traditional hybrid system, dubbed BluePower, could arrive even sooner.

V-12 is too much. Bugatti though could use an extra 4 cylinders.

the 600 series uses a 5.5 V12, not a 6.0.

I have no trouble hearing that they will ditch the V12. The sound is better in a V8. i do not like supercharged engines. N/A engines is # 1. High Performance N/A engines are usually high RPM, and turbo engines are not. High RPM is fun, like the RS4 or M3 engines. Look at the RPM on the BMW 335, it is low.

if they can make twin turbo V8 more powerful than twin turbo V12, what the hell are they waiting for ?

screw turbos/superchargers! make a N/A engine with that much power and it will help mercedes in two ways: 1, people like n/a engines. 2. it would be more advanced than just dropping in a sc/turbo to make the same power. I actually liked the v12 in a 2006 sl600 i drove once. it was very smoooooth and had a butt load of power.

or they can put turbos in the back and a supercharger in the front! that would be sweet for the new amg engines imo!

I remember on Top Gear they featured a Brabus SL 6.5 with a Twin Turbo V12 with 900hp, and it still had a warranty, a buddy on mine, a general sales manager at a high-end Exotic dealer has the current SL 6.5 AMG, and it spanks his own Gallardo, and his brother F430, down grading motor for Benz just may hurt them, besides if you have the cash for a 600hp V12, I think “fuel efficiency” is the last thing on your mind…

It is unbelievable that Mercedes Benz would throw their experience with V 12s away. There is an aspirational value to the 4 extra cylinders over a V 8 which no figures can match. A wrong decision but being Mercedes they will build good cars anyway. I guess those who want V 12s will move over to BMW instead.

I dunno, it seems like everyone is following suit on this. So, I think Mercedes should be OK
I wonder what it means for Maybach, though. Surely they can’t downsize the Maybach to a V8 as long as Rolls-Royce and Bentley are putting 12 cylinder cars on the market. I figure they’ve either got to kill the car or make a genuinely new model.

Well, if future models from Mercedes are not gonna have 12 cylinders, and are not going to be designed with one in mind, I doubt Maybachs will be as well, since Maybach still doesn’t have it’s own model.
I wouldn’t doubt it if Mercedes just dropped Maybach in the current crunch. Really doesn’t matter to me, not much more than loaded Mercedes with a few neat features. If only they looked good as well, and had some publicity behind them (i.e., government officials, famous people, etc.).

This move by MB is good for the environment, bad for motoring. Car magazine said it best: turbo’s are crap.

that is a good point about maybach, what will happen when this goes through, do they die off or convert to V8, personally i think they maybach could use a V16, kinda of a tribute to the pre war coach-built cars

This means no more 738 ft lb ttV12 for the SL65 AMG Black series..bummer that was one sweet car. But I can’t complain about a 700 horse V8. So one way or the other, AMG will still have ridiculously powerful engines.
I didn’t think Maybach had much of a life beyond the current model anyway, and this just sealed the deal.

They shouldn’t ditch the V12’s. They need Flagship models that separates them from the rest of the Line-Up. There needs to be Leaders in the Automobile Market and Mercedes-Benz with their V12 Engines are Leaders in this Market! Keep them going! Don’t give up the V12.. They can try make it more efficient!

I don’t think this would spell the doom for Maybach (at least not this by itself). The Maybach was never about the powertrain–ultra luxury, ultra customization, that was always Maybach’s allure. But sales have always disappointed, mostly because few people want to spend an extra 300 large for a gussied up S-class. It looked too much like an S-class, to boot.
AMG’s been proving Pagani with NA V-12 since day one. If the Zonda replacement ends up having a forced induction 8 cylinder, now THAT would get me bummed.

Congrats, mercedes. You might actually meet CAFE requirements.
Yeah it sucks to see the v12 dissapear. It’s like two inline 6’s at an angle, yeah? that’s gotta be the smoothest configuration you can get.
v12 power can be had with a v8, especially with up to date engine technologies like VVT and direct injection. With shorter gearing and a high compression motor, you can effectively replicate the acceleration of a v12. the only caveat is the exhaust tone since it would run at a higher rpm.
Honda does this with 4 cylinders, even with the disadvantage of engine vibration and noise. It is certainly possible with a v8. This is where the future is headed. Get used to it.

yarddog has it right, if you’re ponying up for a V12 Merc fuel mileage is right up there with the number of cupholders on your priority list. You can now get a V8 in a Hyundai for piston’s sake, so why purposely narrow the gap that much more without making the other guy work for it?

AMG’s move to a V12 isn’t so much about efficiency, it’s because their future designs are getting smaller, and the V12 block is too large.

I like when ricers with japanese sounding names (usually end in bu, bi, ki, ku, ka, etc) (you can pick them off right away) always throw their two cents in when it comes to TURBOEZ, “N/A”, what works best, etc etc cause they’re used to ricespeak.
You can usually find tons of them in posts relating to turbos etc. Just because the word TURBO is used it doesn’t mean we’re talking about little crotch rocket civics. We’re talking legitimate german torque bruising monsters. Not little ricebags!
