We've heard for a while that the next-generation BMW M3 will lose its 4.0-liter V8. In fact, back in July, AutoExpress claimed that the next M3 would feature three turbochargers. Not so, says Autocar. Instead, the Brits claim that "insiders" tell them that the high-performance 3 Series will feature a twin-turbo inline-six. This mill reportedly will be all-new, and not based off the N54 twin-turbo or the N55 twin-scroll engine.

But while the two British mags disagree about the number of turbos under the M3's bonnet, the consensus is that power will be increased to 450 horsepower. What's more, the next M3 mill will boast significantly more torque, up from 295 pound-feet in the current generation to somewhere in the vicinity of 400 lb-ft.

We don't know about you, but 450 hp and 400 lb-ft sounds mighty fine to us. We're trying to table that enthusiasm for now, though, so we'll keep this information in the rumormill category for now. After all, the next M3 probably won't hit newsstands until the 2014 model year.

      8 cyliders is overkill now days with 6's and Turbo 6 cyl egines puting out more than enough power for just about any car or truck...but who doesnt love the rumbling sound of a nice V8?!

        Considering my Evo has over 400hp from a 2.0 4cylinder, I agree. What's better is hearing from other people (without a clue) how "laggy" my car is without realizing I make over 320ft/lbs before 3000rpm and easily run 11 second quarters. Over 1000 horsepower from 2.0 liters has been done. You'd think a 4cylinder is all anyone needs.

          The exhaust note of a 4-cylinder has never really appealed to me. Certain motorcycle engines sound great. Other than that, boosted or not, most 4-cylinders are buzz-bombs. They're also way too common.

          @Jason 4 cylinders can sound great - it is just that most that we have are in economy cars and hence the bum reputation. Driven an S2000?

        V8 rumble is great, but the v8 M3 doesn't really rumble, it's tuned more like high revving formula racer.

      I hope they make another M3 sedan. Turbo-six power is nice, but won't sound as sexy as the N/A Eight. Compromises make me a sad panda...

      i love it.. for years, the Brits, Germans and Italians have criticized americans for their love of forced induction for making cars faster... now? they are finally dropping the high revving, low torque, inefficient NA motors and following the americans. LOL

        hahahahaha forced induction only works well when done properly - you americans only use superchargers though. the turbo was inveted by the japaniese and the supercharger was invented by the british. the thing that we (the REST of the world) hate about american cars is; how on earth can you have a 5.0L SUPERcharged V8 and it only makes 500hp... plus uses an impressive amount of gas. i cannot think of a new automotive tech the americans have come up with in the past 20 years - while the rest of the world is innovating changing and reacting your just lumbering along at stupidly slow speeds with you inneficient though supercharged and absurdly huge V8 musclecar weighing something to the north end of 2 tonnes.

          ya because aston martins sure are light weight vehicles.. o, and so are lamborghinis. and that veyron? super light weight.... the reason we have supercharged V8's making "only" 500 hp is because our goal is to make it affordable to the consumer.. not everybody can afford a 100,000 dollar car, and horsepower costs money. and that's why we have an aftermarket.. so people with money can squeeze out more power. people are already getting north of 550 on the new 5.0L V8 in the mustang, naturally aspirated. innovation? lol.. i'm not even going to go there. although, i will say that americans made some of the most revolutionary innovations in automotive history (i.e. the paramount assembly line, seat belts, airbags, etc.)

          i'm not saying that's the way it is.. simply stating the europeans have always criticized american autos for using forced induction as a means of making more power.. you know, as opposed to making a car cost twice as much as it should and have no torque.

      There is nothing as fun and smooth as a BMW straight 6, especially with turbos.

          Electric cars aren't exactly feather weight there buddy. The Tesla Roadster weighs over 2,700 lbs making it almost a thousand pounds heavier than the Lotus Elise from which it is based. Unless you are comparing these cars to golf carts, your argument disintegrates into thin air.

        ...but cutting edge when compared to your same primitive old argument. They are so primitive that I bet you don't even have to type them out much on here any more, just cut and paste.

        @Javanese
        turbo lag is almost not existent with the modern day twin (sequential) turbos. ever driven an ecoboost ford? there is NO turbo lag, and i suspect this new beemer to be the same way.
        Jordan
        • 3 Years Ago
        @Javanese
        hardly any new BMW's have significant turbo lag. If they go with a tri-turbo setup with the third being electric I think you'll see almost zero turbo lag... not that their current N55 engine "suffers" from turbo lag.
      MechE
      • 3 Years Ago
      Three turbos sounded silly, especially since they weren't accompanied by any sort of breakthrough power figures. Glad it'll be a somewhat standard twin turbo.
        DrEvil
        • 3 Years Ago
        @MechE
        Actually three smaller turbos would mean earlier boost, problem with smaller turbos, is that they peak too early and limit top end boost. Larger turbos have L - A - A - A - G issues.
          tkosoccer03
          • 3 Years Ago
          @DrEvil
          @ GCV you're correct.. that's what a twin turbo is.. it's a sequential set up with a smaller turbo backing the larger turbo to nearly eliminate lag and increase boost at higher rpms.. ford ecoboost motors, powerstroke, duramax, and cummins diesels, and all the cars you mentioned as well.
          GCV
          • 3 Years Ago
          @DrEvil
          Correct me if I'm wrong, but a setup including a small turbo, for low end, and big turbo, for top end, would be able to achieve your stated goals. I doubt a three turbo setup would make sense economically and performance-wise. There is considerable evidence on the market right now that suggests so: Nissan GT-R, Porsche 911 Turbo, Saleen S7, F10 M5.
