2011 Infiniti M56S – Click above for high-res image gallery

Renault-Nissan and Daimler recently announced a strategic alliance that promised technology and facility sharing that could result in the saving of over $1 billion per year. We'll have to wait a while before we can see any parts or factory sharing, but that isn't stopping the rumormill from running rampant.

The latest tease comes courtesy of Japanese enthusiast rag Best Car, which claims that the Infiniti M and G will share a common platform architecture with the Mercedes E-Class. The move would make sense from a money-saving perspective, as Infiniti could save hundreds of millions of dollars in development costs. Daimler could reap huge sums of savings through increased economies of scale, while likely receiving funding from Renault-Nissan to help pay for the costs of developing the architecture. The two companies are reportedly also looking into sharing engines, factory space in the U.S. and possibly even commercial vans.

But while it makes sense for Daimler to share the E-Class platform with Infiniti from a cash standpoint, we're taking this bit of news with a healthy dose of skepticism. Infiniti already has an excellent rear-wheel drive platform and there's a good chance that it's cheaper to build. But then again, if Daimler and Renault-Nissan are truly serious about saving over $1 billion per year, these are exactly the kinds of parts-sharing agreements that will help them reach their cost-saving goals.

      Not going to happen people. Not only does the new 420HP M56 sedan out perform the MB M Class in acceleration, braking,handling,slalom,etc. its also a cheaper platform to build upon.

      More likely to happen is the E Class will switch to the Superior Infiniti FM platform, Nissan/Infiniti Sell more FM platform vehicles each year then MB sales total for all its vehicles.

      Again just like the MB engine swap rumor this is just a rumor and will not happen. What this joint venture is all about is MB wants in on Nissans new commercial vans and industry leading battery technology. Nissans engines > MB engines in both power/efficiency/reliability.

      Infiniti VQ > MB V6
      Infiniti VK > MB V8

        Just to make it more clear for you:
        E350 - 3.5L 268hp @ 6000RPM 258ft-lb @ 2400RPM
        SLK350 - 3.5L 300hp @ 6500RPM 265ft-lb @ 4900RPM
        M37 - 3.7L 330hp @ 7000RPM 270ft-lb @ 5200RPM
        See a pattern? It's all a matter of tuning for the application at hand... MB tunes it's engines for the specific car it will be used in, while Nissan just shoves the same engine into everything from the 370Z to the M37. Never mind that one is like 800lbs heavier than the other and is a luxury cruiser as opposed to a screaming sports-car.

        "Infiniti VQ > MB V6"
        In power output? Sure, but just a bit. Similar torque output with MB V6 having more of it lower in the power band, very important for 4,000lbs vehicles. The extra power from the VQ comes in above 7000RPM...
        In terms of quite/smoothness? lol... the VQ slots above the original odd-fire Buick V6s... but that's about it.

        "Infiniti VK > MB V8"
        Remains to be seen...

        I dunno about you but acceleration is only one factor that comes into play when talking about engines, the other is reliability. I dunno about the MB V6 in the 3-3.9l class, but I know the Nissan VQ motor in some form was on Wards 10 best list for 9+ years, something no other manufacture could claim. That has to say something about how good the VQ was, and potentially still is.

      I know that these sort of arrangements occur all the time, but Mercedes and Daimler-Nissan? Anyone else struck with the sudden fear that in fifty years the only car that will be available anywhere is the Mercedes-Daimler-Nissan-Ford-Volkswagen-Chrysler-Fiat-Toyota-BMW-Honda POS 3000?

      • 5 Years Ago
      "Daimler could reap huge sums of savings through increased economies of scale, while likely -
      over charging Renault-Nissan for consulting, engineering, and parts just like they did to Chrysler
      - to help pay for the costs of developing the architecture."

      There. Fixed it for ya.
      • 5 Years Ago
      Curses, I liked that Inifnti was a great mix of reliable and fun.

      Unlike Acura (save for the NSX) and Lexus.

      If I wanted an MB, I'd buy an MB.

      LX was 100% home grown, FYI - the Merc trans & prop failed Chrysler testing, a decision was made to accept it as is by Germany, basically saying they were not changing,. As for the Pacifica - It was based on a minivan and nothing to do with the Germans.

      Grand Cherokee scenario:
      Mercedes and Nissan will design the platform, Nissan will pay for the platform, Mercedes will divorce Nissan, claim the platform is theirs, then withhold parts from Nissan so they can't build their cars.

      Chrysler LX scenario:
      Nissan will ask for help with final tuning of the suspension on the next gen FM, Mercedes lets them reverse engineer the suspension on the current E-class as the new one's about to come out.

      Crossfire scenario:
      Nissan asks for help building the next generation M-class, Mercedes shoves the old E-class down their throats, which Nissan's then forced to wrap an expensive (and ugly) new Euro-designed body around and try to sell for $50k here in the States. And to top it off, the interior is spray bombed in cheesy silver paint.

      Carlos, I hope you know exactly what you're doing there. I don't know if Chrysler's blameless, but it still feels like a case of domestic battery.

      So, what does this mean to the Nissan Z, and Infiniti FX as they also are on the FM platform of the G line and similar to FM platform on the M line. The 370z is already a very good car, and moving it to the E-class platform to me sounds like it some how gonna gain some weight, and some how take some of its fun/charm away. Unless, they use the C or the SLK platform for the Z?
        • 5 Years Ago
        Somehow I'm very skeptical that Diamler is willing to give the most technologically advanced platform in it's class to any of it's competitors... or use any Nissan parts. I'm not a MB fanboi, quite the opposite... but if you ever drove any variation of the new E (especially the E63), you know what I mean.
        • 5 Years Ago
        I'm wondering if it's backwards. Why would Infiniti move their vehicles to the Daimler platform if the Daimler platform is costlier to build? If this rumor is true, I expect Daimler to be the one doing the moving, not Nissan.
        • 5 Years Ago
        Especially because Nissan already have decent economies of scale with their widely-used (and highly acclaimed) FM platform as well as their ubiquitous VQ-series engines.

        I would understand Infiniti collaborating on a next-gen E-class platform upon which to reintroduce their previous Q flagship, or moving the M upscale... but using the E class platform to underpin the G especially makes no sense.

        Aside from range-topper luxo-barges and SUVs, I don't see what Infiniti has to gain from using E-class architecture on their G, which already has DNA (90% match, almost) from the Z car as well as the optional AWD system derived from the GT-R. I don't see any sense in diluting that pedigree.

      The last time the Germans,French and the Japanese got together was during World War 2.
        • 5 Years Ago
        Uhh, that would be the Germans, Italians, and Japanese.

      Chrysler's LX platform is all-Chrysler and American engineering, it is not a rebodied E-Class as widely thought. Chrysler copied some of the engineering after the merger with Daimler but it is purely their own work. Nobody will ever mistake an LX for anything remotely German behind the wheel.

      The Crossfire was a Chrysler-styled Mercedes SLK and built in Europe. Aside from that the only other vehicle Mercedes and Chrysler will ever share is the current ML and upcoming Grand Cherokee which were jointly engineered before the divorce.

      I've already read that the next gen V6 in the G and M will be coming from MB
      Possibly even the V8 for the next gen M will be MB one - let's make that the 6.2L NA engine w/ 500HP +

      maybe that'll fit well with the IPL that Inifiniti is looking to bring out

      too bad though about the reliability - the cost of ownershif for Infiniti is going up and I don't like it

      maybei'll grab a 2011 G37 and keep that for at leat 10 years - my current G35 is on the 7th year now and boy has it been good to me.
        • 5 Years Ago
        the new IPL line probably wont feature MB engines in G or M series. G and M series will have twin turbo or single turbos put into the stock engine. Give it about a 100bhp increase or some. The only thing that make sense in the merger is that MB will use inifiniti's chassis. and Inifinti will use MB's big size chassis for possibly new cars that is bigger than the M like the old Q. infiniti will end up most likely be using MB's v8 for their SUV. The G and M are great sedans/coupes the way they are, and i think inifniti is smart enough to know that.
        • 5 Years Ago
        "I've already read that the next gen V6 in the G and M will be coming from MB..."

        If that's true it might be based on the Pentastar V6. Some say that Mercedes is still going to use the new engine - or at least the short block - as the basis for their new V6, which was the plan before Daimler divorced Chrysler. Of course if they end up doing that they will never, ever, admit it.
      • 5 Years Ago
      Remains to be seen what Daimler actually does. Hopefully Nissan/Infinity has learned from what they did to Chrysler and has a far better contract for sharing. Otherwise Infinity will get ancient platforms and tech while Daimler uses the money to build their product.
      • 5 Years Ago
      FIRST RENAULT, NOW MERC... THIS IS HOW NISSAN WILL DIE !!! JOINING CRAPY CAR MAKERS...have you see a merc capable to take some turns??? NO have you seen a good french car ..NO!!! ...sorry about nissan
