2010 Mercedes-Benz S400 Hybrid – Click above for high-res image gallery

Mercedes-Benz has confirmed to Autoblog that the S400 hybrid won't remain the only efficiency-minded member of the S-Class family for long. The S350 Bluetec will be coming to the U.S. market for 2011 as the first diesel S-Class since the mid-1990s. The S350 will use the same 3.5-liter turbodiesel V6 already used in Mercedes' ML, GL and R-Class SUVs. That engine is rated at 210 horsepower and 400 pound-feet and includes a urea injection system to treat the NOx emissions in the exhaust.

We expect the S350 to at least match – if not beat – the 22 mpg real-world results we achieved with the S400 gas-electric earlier this year, and it will probably have similar performance thanks to its exceptional torque. There is no word on pricing, but we anticipate it will sticker at or below the S400's $87,950 base price for 2010.

      It would make more sense to put this diesel engine in a C-Class than in the S-Class. Imagine a C350 Bluetec with 400 lbs/ft of torque and much better gas mileage as the C-Class weights much less than a S-Class.

      BMW already offers a 335d. How well is that selling?
        • 4 Years Ago
        The 335d sells poorly.

        But I agree this engine makes more sense in the C class than in this car. Unfortunately, in the C class it'll suffer the same problem the M-B GL350 does or to a lesser extent the 335d does. Who buys a Diesel to get mediocre gas mileage? And this engine is too large to get truly good gas mileage in the C-class. This would be a good engine for the GLK or the E-class. In the C-class they should be offering a 2-2.5L 4-banger turbo Diesel.

      I think this is a good move for Mercedes. In years past, Mercedes used to have a gas V6 and a smaller gas V8 as their "fuel efficient" options in the S-Class sedans. These new engines (Hybrid and Diesel) essentially replace those that are now missing from their lineup.

      I mean, sure, the main options are the S550 and S600, which are great and all, but not everyone needs 390+ hp in their Mercedes. For the people that want a more fuel efficient/greener alternative, you have a choice between a Hybrid and a Diesel. This makes a lot of sense, as you can tailor your purchase to the type of driving you do. Spend a lot of time on the highway, go with the diesel. Spend a lot of time in the city, the Hybrid should shine.

      I could also see the diesel becoming a popular vehicle with affluent livery and car rental companies if it proves to be reliable in the long term and better on fuel.

      Where is the mb 3.5 litre diesel v6?
      • 4 Years Ago
      I have a 2005 E320 CDI and love it. Its been wonderful for 180,000 miles and doesn't seem to want to quit. I've maintained it by the book and have had only typical problems with it.

      If I had the cash flow and needed another car, I would consider the S350 Bluetec in a minute for its long distance prowess, comfort, and safety. Would keep it a long time so overall costs would be OK.

      If European pricing is any indication, it should be priced significantly below the hybrid.

      Current base prices, without VAT:

      - Diesel: Euro 61.950
      - Hybrid: Euro 72.300

      All these whiners complaining that this model can't go from zero to sixty in 2 seconds flat miss the whole point. There's a LOT more to drivability than just zero to sixty times.

      With fuel economy's influence on design, most cars are chugging along at maybe 2,000RPM when you are cruising at a steady speed, often even less. Multi-gear transmissions are set up to ensure this. With an engine like this that produces its maximum torque consistently from 1,600 to 2,400RPM (see for example http://www2.mercedes-benz.co.uk/content/unitedkingdom/mpc/mpc_unitedkingdom_website/en/home_mpc/passengercars/home/new_cars/models/s-class/w221/tech_data.html, where this model has been available already, along with several other engines), you have ready access to all the passing or merging power without even requiring a downshift or three to reach high RPM ranges.

      Like Paul mentioned, the different drivetrains are most appropriate for different driving styles. If you do mostly city driving, that plays to the strengths of most hybrids. Highway miles play to the strength of diesels. A 7.8 second 0-100km/h factory rating (see the previously mentioned link) will certainly not leave you at risk, unless you spend all of your S-Class time on the dragstrip, and the power curve I referenced above will make ordinary driving (as opposed to S-Class autocrossing) feel like the car is rated even higher.

      The original diesel S-Class was the 1979 300SD W116, which was offered ONLY in the United States. For those that appreciate automotive engineering and its history, which would include fans of other makes like Porsche and Ferrari, a diesel S-Class is close to a perfect vehicle.

      Klatta-klatta forever, baby.

      Jesus, Mercedes! all I want is a SWB S class in America again (and no more R classes) is that so much to ask for?

      I've got a 2010 VW Jetta SportWagen TDI and am loving all aspects of what it provides.
      VW is already on their next step with turbodiesel/electric motor/battery hybrid development but one would expect at least the same from Benz earlier and sooner? BMW's turbodiesel motors are today's best tho imho but VW across all it's brands probably outsells everyone else. Why haven't US, Japanese and Koreans cought on to diesels yet?

        "The idea that a majority of their grown is from Diesel seems pretty tough to me since you listed 3 cars that don't really sell well. EVERY A3 could be a Diesel in the US and it wouldn't amount to much for them."

        What's your problem? Seriously. You're not stupid, I know that, you're actually pretty smart, but on this issue you just keep being a tool. Audi's press release says the A3 TDi's are once again 60% of sales and that the model's selling better than it has before. Those numbers relate to AUDI not to the entire market. Whether or not it 'amount to much' doesn't matter. The discussion is growth of diesel and american acceptance. if 60% of a model sold is diesel, that's significant, especially for audi who wasn't selling a3's so hot.

        When we discuss growth in ANY sector do we relegate it to pure numbers or do we look at how an automaker specifically has done. I guess where you're getting confused is the position that vw and audi diesel sales are a small hard number in the market. I don't care, I'm talking % of sales. VW and Audi sales in pure numbers have been low because the US isn't their primary market, or secondary market. The reason I advocate americans have no issue with diesel is VW and Audi have the greatest variety of diesel amongst their brands, so no, we're not seeing toyota numbers of sales because, at a very elementary level, NO ONE ELSE IS SELLING DIESELS IN THIS MANY MODELS.

        Following your logic, I'm guessing because mercedes sells so few hybrids there just isn't any interest in the US because mercedes hybrids account for such a small portion of total vehicles sold. americans also, apparently, just don't care for sports and supercars priced above $100,000. The camaro is a flop because really, no matter how awesome it's selling for chevy and how much that segment's % of sales haven't increase, it's irrelevant because they're a small drop in the overall market.

        Let's not bs, let's be consistent. When discussing how an automaker is doing in a various field we compare their sales to what they've been before. If we want to see if the new malibu is a success, we compare it to previous sales. if we want to see if the new fusion is a success we compare it to previous sales. THAT, quite bluntly, IS how the automotive press measures the success of a model.

        zamafir:
        Back those figures up please.

        That math is unworkable. The idea that a majority of their grown is from Diesel seems pretty tough to me since you listed 3 cars that don't really sell well. EVERY A3 could be a Diesel in the US and it wouldn't amount to much for them. Jetta wagons do better but are still a relative rarity.

        Nissans been building diesels over seas for decades, in fact Nissans new V9X diesel is a a little smaller at 3.0L and makes 238HP/406TQ and averages 28MPG. Thats more HP/TQ and better fuel economy then MB bigger 3.5L diesel. Nissan/Infiniti just focus their diesels on the japanese/european markets. Hopefully we will be seeing the new V9X engine here in the US soon...

        @Liscia - caught on? 84% of jetta wagons, 60% of A3s, 36% of Q7s, the majority of VAG's avg 38+% unrelenting growth purely a result of diesel sales? yeah, man, if only diesel would 'catch on', they maybe we could see something impressive like 100% growth. Amongst automakers who never retreated from diesel and who have the biggest lineups of diesel, there's nothing but significant and in some cases exceptional demand.

        Liscia : Why haven't US, Japanese and Koreans cought on to diesels yet?


        Because they opted for hybrid technology which yields far better results.

        Jetta TDI diesel does 35 - 40 mpg (if you're careful) but Toyota Prius does 50 mpg.

        40 mpg is what you achieve in a Ford Fusion or soon to be released Hyundai Sonata hybrid, both cars being much larger and more powerful than Jetta diesel.

        Lexus RX450h hybrid with its 28 mpg is way beyond what BMW X5 or Benz diesel are capable of.


        If you consider that it takes less oil (so less Iraqi war) to produce a gallon of gasoline, the difference becomes even more pronounced.

        So sorry, like it or not, hybrids do better. German car makers know it very well, that's why they came up with S-class hybrid. It offers diesel mpg and carbon footprint while being much more powerful and faster. Now it's time for them to make the affordable version of this system, maybe in some C class, and to go for small plug-in systems as soon as possible.

        @apex

        My dad has an 08 ML320 CDI and while it is rated at 18mpg city, I can say without a doubt that he averages 22-25mpg on average in the city without any trouble at all. In comparison to my car which is also rated at 18mpg in the city, my car doesn't even achieve that mileage sometimes when I drive it in the city (Boston).

        The EPA mileage doesn't accurately affect the benefits that diesels have over gasoline engines, but they are definitely worth the money.
      • 4 Years Ago
      Makes sense for this big boat to have a diesel - all that torque for low-end grunt, better mpg's and skips all the battery/tech in current hybrid systems. The Germans have this whole diesel thing figured out pretty darn well...
      • 4 Years Ago
      Yawn, the mil's federalized and already in a few models, put it in the c class already
