We've just received a set of spy photography that, for once, is focused on what is inside the car rather than what is visible on the exterior. That's exciting stuff, as the car in question is the next-generation BMW M3, and the engine in question is the stuff of great import where enthusiast drivers and Bimmerphiles are concerned.

The most important fact revealed from these shots, is that the 2014 M3 will be rocking an inline-six engine in place of the high-revving V8 from the current car. That news is welcome on two fronts: it represents a return to the engine configuration that we most associate with BMW performance, and it suggests a further development of the six-pot we've come to love in so many of the brand's current models.

The photos confirm that the engine is likely two have turbochargers at least (there are two pipes feeding the intercooler), and they do not contravene rumors that a third, electric turbo lies just out of sight.

Displacement figures for the engine still remain a bit of a mystery. It has been reported that the next M3 could be as voluminous as 3.3 liters, though it's more likely, based on a BMW tech report claiming use of optimized, 500cc-cylinders, that the total size is 3.0 liters. In any event, everyone's best guess about power output hovers around the 450-horsepower mark.

Please also note the very sturdy strut tower bracing that is visible under the hood (as if you could miss it). Forego any worries that the new hot 3 Series will be anything less than rock-solid mid-corner.

When you're finished browsing our photo gallery, please to continue on below, where we've posted some video footage of the 2014 M3 testing in Germany. Engine pics go better with engine sounds, no? Scroll down to check 'em out.

      I'm excited to see this M3 and an ATS-V head-to-head in the future. Both cars are going to be great for us enthusiasts.

      That looks like the inside of a Mac Pro.

      Good news i hear some clips with no exhaust crack and a subsequent drop in RPM that can only come from some test drivers left foot hitting the floor. Manual should be around for one more generation folks.

        That sounds actually precisely like the dual clutch input shaft pop of a dual clutch box like M-DCT.

      haha I have lost so much faith in the users of Autoblog after reading the comments... Whoever said the car doesn't sound turbo-charged has been watching way too much fast and furious

      I like it, I respect BMW for getting high levels of performance with good efficiency. These are the times we live in, in which mileage and emissions are of paramount importance. If you compare it to the 70's this is infinitely better. I'm still hoping for the continued existence of the manual transmission though.

        I think BMW is done with the manual transmission in the M3 as well. But at least you won't have to listen to that God-awful V6 burble coming from its pipes anymore.

      An M3 with a turbo. It's simply sacrilege. M// cars are supposed the be super-high revving, especially the M3. It will have lost all its character if they take away that. BMW is kicking the enthuisasts to the curb.

        Blame environmentalists. That's what I do. Also, we knew this was coming.

          Yea, who cares about the environment and global warming. The hell with the planet. I need cars to look at on the internet.

          @Gypsi, Go back to reading your Greenpeace blog, and leave Autoblog to the car enthusiast.

        Nobody is mad that the v10 is gone from the new M5.

          You kidding? I've always considered the V8 and V10 some unique and positive attributes of the now-previous generation M cars. Better fuel economy be damned, hearing those high-strung engines wail puts a grin on my face every time.

      So let me guess, its probably cheaper to replace the engine than change a sparkplug?
      Teleny411
      • 2 Years Ago
      Heres an idea... Stop makIng the car so big and heavy and a naturally aspirated, revving straight 6 sans the tubos (lag & unreliability) will do...

        judging by the short piping and the water/air intercooler, lag isn't going to be an issue.

          I still think there will be lag and a turbo engine is not the nature of the beast. Plus BMW twin Turbos are not known for reliability.

          Lag is always an issue. You cannot eliminate it in a turbo setup, it's a physical impossibility. Especially when you've come from a traditional M engine, these turbo engines do not have the characteristic throttle response.

        Agreed agreed agreed, but can only click once... The M3 what the M5 use to be...they should have just left the V8 in there...and put the V10 in the M5 which has become a M7...

          yep... No need for the turbo lag and horrendous reliability and durability.

        Actually, I think that they may have invented one. This is a turbocharger that primarily gets its rotational energy from the exhaust like normal, but it has an electric motor that assists it to get it up to speed to decrease turbo lag. The motor only energizes to accelerate the spool.
        Ducman69
        • 2 Years Ago
        WRONG, there are electric turbos. Turbocharger means it is driven off the exchaust, and they are, but they have a motor between the impeller and compressor sections that allows the turbo to spool up to ideal RPM quickly at low RPM to avoid lag. Once under boost and up to speed, it also becomes a generator.

      This thing has to be turbo'd right? No way can a 3.0 or 3.3L pump out that many horses, but they didn't mention any turbos. Hmmm
