Another M vehicle is spied during a testing session at the famous Nurburgring. The 2013 F80 BMW M3 Sedan goes around the track for a new trial before its release next year. Initially introduced in a sedan form, the F80 M3 will be followed by the Coupe and Convertible variants, all using the same engine.

And this is where they mystery comes in plan. Previous reports were associating the new M3 with an inline-six engine while more recent ones point to a radical change in BMW M’s philosophy: a turbocharged V6.

Some of our sources says that the V6 is a 3.3 liter BiTurbo engine with around 450 horsepower, an information that has been denied by others, so at this point, any news around the new M3 engine are to be taken with a big grain of salt. To add even more fuel to the fire, Car and Driver has recently published their own opinion on the V6:

“The new V6 will be the first to mount its two twin-scroll turbochargers within the vee-angle, mirroring the company’s 4.4-liter V8 design. The This unique-to-BMW approach reduces the length of the inlet tract compared with a regular turbo-vee setup, helping to sharpen throttle response and minimizing heat buildup after air passes through the intercooler. A 60-degree V6 will also offer the best balance, but a 90-degree angle is needed to fit the two turbos.”

In this week’s interview with BMWBLOG, Dr. Friedrich Nitschke, BMW M CEO, refrained from offering further details on the powerplant, but we were left with an important tidbit of information: the new M3 will be lighter and will make extended use of carbon fiber parts.

With another year of production, the E90/E92 M3 might be the consumers’ last chance to grab a V8 naturally-aspirated engine.

The test mules shown below reveals the wide track specific to M products, as well as M front bumper, square LED headlights, large brakes and the signature four exhaust pipes at the rear.

    i’m sorry bmw is putting turbos, not just because i don’t like force induction, the point of M should be to make a car special, not just, tune the suspension, put huge turbo engine and we’re ready to go. That’s the AMG and Audi way, BMW way should be manual+naturally aspriated engine and car which weights 150-200kg less than cometitors from merc and audi.
    new m3 will be amazing, i’m shure but it’s just not enough!
    btw. I’m for V6 twinTurbo rather than inline6 twinturbo

       NA will always be NA, you support it because it has the fastest throttle response and equal power through out the RPMs..  and that is BMW’s philosophy. With what we have seen from BMW, they are making FI engines with that philosophy. That being said, I’m keeping my s54–the last inline6 NA M-power.

       Thanks dude, I didn’t know the MB C63 AMG and the RS5 engines were turbocharged. Please keep us updated, to seem to know a lot.

    If BMW really is going to make a V6 (which disgusts me) why not make it 120 degree design?  It would better for handling due to the lower center of gravity and isn’t it smoother than a 60 degree design (720/6=120) while allowing more than enough room for the turbos?  The one downside would be that the inlet tract would probably slightly longer.  

    • Gord says:

      I believe the reason why people suspect a V6 is because they are assuming that BMW will use a V6 of the M5’s V8, much like how the E90’s V8 engine was based off the old M5 V10.

      With that said, I assume the new engine will probably be 90 degrees because that is what the current M5 configuration is.

        But BMW ‘M’ or not is still a luxury brand and a 90 degree V6 is not luxurious.  Adapting the V8 from the V10 made sense since the V10 was 90 degrees (interesting that it wasn’t 72).  It seems that there’s a lot they could do to the I6 to further reduce turbo lag other than a reverse flow 90 degree V6.  

      • Nnnn says:

        Gord, you mean slice 2 cylinders off the existing 4.4L V8?   That would give you the 3.3L displacement.    Detroit was doing this back in the 80s and those engines were pretty rough, as I recall, because a V8 is generally 90 degrees and a 90 degree V6 needs balance shafts which the block won’t be provisioned for.

        This V6 idea makes no sense to me.  WHY do it at all, when you have a mature, robust 6-cylinder engine with tons of headroom that they’ve already dumped tons R&D into?

        • Nnnn says:

          plus, the benefit of squeezing the turbos inside the V only makes sense on a twin-scroll turbo fed by lots of cylinders.  You would not have *twin* twin-scroll turbos with a six-cylinder engine without very complicated exhaust plumbing.   So it would have to be a single twin scroll turbo, because there is zero benefit to putting two traditional turbos in the V, and thus no apparent benefit to having a V6.

    I don’t mind if they use a V6 (okay, yeah, I really do, but I’m going to put that on the backburner for a second) as long as it can do everything an i6 can: fast throttle response, high redline (say 7500+), smoothness and a good sound. The video indicates that it has the sound part covered, so that’s one down. IF it can cover all those bases (if) then the only reason to complain about a V6 is puritanism.
