In 2013, BMW will introduce the new F80 BMW M3 Sedan. In this new spy video, the upcoming M3 can be seen during the winter testing sessions in Northern Europe.

The 2014 BMW M3 Sedan builds atop the newly unveiled F30 3 Series and will incorporate the usual M design cues, both on the inside and outside.

The prototypes spotted reveal a typical M3 with a wide track, M front bumper, square LED headlights, large brakes and the signature four exhaust pipes at the rear.

The biggest mystery comes from under the hood. We initially reported that a V6 engine with three turbochargers was being considered to replace the award-winning, now retired, V8 naturally aspirated unit, but recent reports indicate that BMW will most likely use an inline-six turbocharged engine.

Will there be a third turbocharger like the electric ones revealed in the new M550d? We will find out later this year.

    I’ve always maintained, it will not be a V6. Maybe it’s going to be a four!?

    • Whatareyouhigh

      From a V8 to a straight-4? You high?
      Would be nice to have an M3 that’s engine is smaller than the 1M’s huh…
      It’ll be a straight-6 with more than 2 turbos.

      • auaq

         Yup! Only straight-sexy and no vee-sissy engine!

    • Giom

      No sence of humor, these people… :)

      As for inline 4, I bet we will see it in next generation of M3 after the F30 M3. 

  • wazon8

    Finally, the end of V6 rumor in upcoming M3. :)

    • LaMa

       whats wrong with a V6 with 2 turbos in the V ?  I don’t get it why people so obsessed with that V6 trouble ? The V6 engines are very smooth and powerful. I personally like them and would have zero problem with them in the BMW. As far as service issues, much better then the I-6 which is tucked under the windshield, so cyl # 6 is all but invisible.

      I think it would have been a nice change, a 3.0l Twin Turbo with 450HP and lighter weight, better weight distribution, easier maintenance, cheaper build cost, etc. It only makes sense, as they have a dominating V8 already in anything above 3 liter. Just cut 2 cylinders off and create a 3.3l V6 with Twin Turbo, making 420-425HP. Easy to do and would reduce development and build cost.  They could use the same rods, pistons as in the M5/M6 and same injectors, valves, etc etc. 

      The old I6 design is oke, nothing is wrong, but its not an ideal engine design for Turbo and for  performance engines. Since BMW said that by 2018 all of their engines will be Turbocharged, and they also stated that engine parts sharing will be a lot bigger then before… I hoped for a 3.3l V6 TT.

        Fist of all, despite what you write V6 are not very smooth as any engine with odd number (in this case, 3) of cyliders in row. They generate end to end vibration because of upward force is generated by first cylidner and downforce is generated by third cylinder. 

        Second, I don’t get why you think that V6 is overall lighter. In order to reduce end to end vibrations (reduce – not eliminate), V6 engines needs to be equipped with pretty complicated crankshaft which weights much more than simple crankshaft in inline-6. Moreover, despite the first appearance the engine block of V6 is not lighter than the engine block of inline-6: That’s true that it’s shorter, but it’s wider in place where heads connect with it. Usually two three cylinders heads weights more than one 6 cylinder head. 

        Third, you’re deeply mistaken if you think that you can get V6 by just cutting out 2 cylinders from V8. In V8 you’ve got simpler crankshaft because there is no need of reducing end to end vibrations generated by odd numbered rows of cylinders, whereas you need to have more complicated crankshaft in V6. In result, you need to have a radically different engines blocks in true V6 engine and in apparent V6 that you would get, if you cut out 2 cylinders from V8. The block of the last one is not prepared to work with the complicated crankshaft, so it needs to be totally redesigned. In effect, you need to build wholly new engine that has not much in common with V8. So, there is no savings here! Contrary to that, inline-4 has number of features in common with inline-6, virtually you can get the first one by cutting out 2 cylinders from the last one. And since BMW makes both types of engines, here is where savings come. 

        Forth, why do you think that “inline 6 is not an ideal engine design for Turbo and for  performance engines”? The perfect inline-6 turbo charged engines provided by BMW are clear counter-examples to your thesis and the upcoming M3′s engine will be another one.

        Fifth, why do you write about better mass balance, when BMW builds cars with 50/50 weight distribution? How can it be better?

        Pwned.  Not to mention, the V8 is 90 degrees and the V6 would need to be 60 degrees.  I would love to see a 90 degree V4 putting out over 300hp for the 1M. 

        • wazon8

          Yes, in most cases V6 is 60 degree, but there are exceptions and the most notable one is Honda NSX’s 3.0 litre V6 90-degree engine. 

          As for V4, I would prefer to see perfect inline-4.

          • Anonymous

            There are definitely exceptions to the 60 degree V6, usually they’re out of laziness though, i.e. cutting two cylinders off of a V8.  The NSX is one of the few relatively recent designed from the ground up 90 degree V6′s.  60 degrees runs more smoothly.

            A 90 degree V4 is more compact and runs more smoothly than an inline 4.  It’s also more expensive, in terms of production and maintenance though.  Much like the perfectly balanced Flat 4.

      i tell you the truth, you would’t know how reliefe i am.

    BMW, instead of getting shaky of whether to choose a Straight 6 or a V6, why can’t you go for a Flat-6? It uses less space and it has a significantly low gravity. I mean, you want to build the ultimate driving machine right? Well it could be too late for me to say this for the F80 M3 and F82 M3 but you should apply this engine format to your future models. Oh by the way, please mention or patent me since I came up with this idea! Thank you for reading, regards from Tokyo.
