Twin turbo V8 in S550/S500

Is Germany getting the 4.7l V8 TT in the S500 in 2011? Select S500 to see technical data, 320kW and 700nM.

http://www.mercedes-benz.de/content/...ical_data.html

What engine is in the US 2011 s550? Or are we getting the new engine as an early release 2012 model?

This has been discussed here many times. The new TT for Europe, the old NA engine for US in MY2011.

Once again, not on the S550. Why check third party sites if the information is on www.mbusa.com?

Guys, this is not freakin hard. Go to the website, a dealership, your local K mart. They all list the same 382hp motor for the US in the current 2011 model year. This is not rocket science, the cars are on the road for Pete's sake...

2011 S550 are already in stock at most US dealers.
No changes in powertrain until 2012 model year.

Here's a S500 V8 TT road test in Europe.

http://www.youtube.com/watch?v=mC7VxFJE128

Let's see when MB brings it over to the US in 2011. Timing is great as the lease on our 08 S550 runs out in 2011.

That new engine is a great piece of engineering to be sure, even if the mandates requiring its production (CO2 reductions) are nonsense. Hopefully some of the other euro enviro features like start/stop, and this on/off oil pump - don't make the US market. Between this new engine, and the crashing US dollar, the 2012 S has got to go significantly up in price.

Crashing US dollar? I take it you don't follow the currencies much.

I doubt the price will go up significantly, if at all; the new engine is a must to compete with the other brands, it is not something that commands an additional premium.

Start/stop is coming and US $ is about 20% up vs last year.

Really awesome. That type of power makes me finally truly prefer a 550 4MATIC over a 600.

Also, anyone know if it will still be called the 550 here in the US?

I hope not, I would prefer the classic 500.

I doubt they would go back to 500. Lately the numbers on the trunk have nothing to do with the engine anyways....

I guarantee you that start/stop will be able to be turned off on US cars, because its not credited as part of the EPA mpg test anyway. US buyers don't want a car that stops at a light, too many of them will panic and think the car has stalled.

We are talking about the 2012 model here, still won't come out for a year, the dollar will be weaker by then because of the Fed QE2.

Really, they need a model below the S550 now (not the hybrid, no one wants those either). This 2012 car has too much HP for the typical US buyers of the S. They need a biturbo V6 making around 350HP, providing a lower cost entry point for the S and a higher MPG car as well. Similar to what Porsche has done with the Panamera.

How can you guarantee that? It is much easier for Mercedes to test just one configuration; I'm sure there are reasons beyond just the mileage.

Dollar will be weaker than what? I would actually expect euro to be much weaker than the dollar due to a whole myriad of socioeconomic factors and fiscal pressures. QE2 is a drop in the ocean compared to the chain of European "bailouts," mainly smoke and mirrors; think of the balance sheet that will need to be to unwound and what effects that will have.

Update from Edmunds Inside Line:

"2011 Mercedes-Benz S-Class: There will be a few minor changes to the S-Class lineup for the 2011 model year. In November, the S63 AMG model will switch over to a new 5.5-liter, twin-turbo V8 that develops 563 hp. The V12 S65 AMG model will also get upgraded to produce 621 hp. Later in 2011, an all-wheel-drive S350 Bluetec diesel model will join the lineup. It will be powered by a V6 producing 241 hp and 469 pound-feet of torque.

2014 Mercedes-Benz S-Class: The next-generation S-Class is scheduled to arrive in 2013. In addition to the expected styling changes, Mercedes is considering an all-hybrid lineup. The idea was floated to dealers recently to a lukewarm response, so Mercedes may scale back the plan to include some traditional engines as well."

Porsche allows disabling of start/stop, its meaningless for the US market. Hopefully MB knows their US buyers well enough to understand - although when I read about ideas for an "all hybrid lineup" for the S, I wonder about that. If MB ever did that for the S, 7 series/Panamera/even the Jag XJ sales - would go way up.

They can't be this crazy - don't they see that the S400 doesn't sell? Buyers in this segment do not want hybrids, period. They would be far better off putting a biturbo 6 cylinder in the S in the 350-375HP range, price it a little lower then the S550, it would sell well enough and provide better mileage towards the fleet average.

This might have something to do with the fact that the S400 can't be had with 4MATIC. I for one would not consider a car that turns into a pumpkin whenever it snows. If you look at the 550s the majority are sold with 4MATIC so the S400 lacking this feature should affect sales.

At least in Los Angeles the market has spoken on the S400 and they are very rare. It doesn't help that the cars are only 2k apart. For that you get 8%-20% better fuel economy (and much lower emissions). You also get a car thats 25% slower to 60mph; more so slower at highway speeds. It doesn't help that the MB 3.5L is a non competitive engine. For example the Lexus V6 produces 306hp vs. 268hp for the MB while returning 2 more mpg on the highway (IS vs. C-Class).

So for the S400 to make more sense they need to start by delivering a competitive V6 and then either move it down in price or achieve better MPG gains versus the V8 at the current price. Start-Stop technology would be a good start. Perhaps a full hybrid system instead of this mild system which was co-developed with GM (,Chrysler and BMW) of all companies. It's the 2-mode system we see in GM cars hooked up to Li-Ion batteries. It's also received some poor reviews for being too jarring in its mode switches.

I would opt for a diesel before I ever punished myself with an S400. BMW is making some diesel cars that are nearly as fast as the turbo 6 yet get 35+ mpg. MB has to go a little further with their tech, but I would accept driving one over the 400 any day...

Start/Stop works only with transmission in "C" mode,put it in "S" and it's off.
At least that's the way in the new S63 and I doubt they would make it different for the S550.
As far as $ is concerned only time will show and with Euro Union bailout of Ireland Banks (and soon Spain,Portugal,Italy),all bets are off....

Agreed that the diesel would be more attractive or even a diesel hybrid. Friend of mine is getting the a bluetec diesel E. Looking forward to seeing how that drives.
