The new Mazda3 is a stunner, both aesthetically and from a driving perspective. As with all good things, though, there's always room for improvement. That's where the wizards from Mazdaspeed come in. Mazda's in-house tuner has been tweaking and turbocharging the five-door Mazda3 since 2007, with impressive results.

We've shown you renderings of what the third-generation Mazdaspeed3 could look like, and for the most part your response was quite positive. Now, AutoExpress has come out with details of just what might be under that long hood. According to our friends across the pond, the new Mazda3 MPS (that's what the Speed3 is called in Her Majesty's auto industry) will be arriving with a new, high-revving, naturally aspirated engine. Wait, what?

Yes, if the rumors are to be believed, the next Mazdaspeed3 will ditch its turbocharger. According to an anonymous engineer, the new MS3 will arrive in December (this is for the UK market, mind you) with a 200-horsepower, naturally aspirated engine. The 2.0-liter mill is based on the Skyactiv engine in the new 3, and should be capable of a sub-seven-second run to 62 miles per hour.

Now, we strongly encourage you to take these rumors with a grain of salt. There are a lot of things that don't add up here. With 200 horsepower, the new Speed3 would be down over 50 horsepower on the original model. It'd also be easily outgunned by the competition from Ford, Subaru, and Volkswagen. And what about torque? The only way we can see a 200-horsepower Mazdaspeed3 working is if it weight is dramatically reduced. Considering weight savings is a tenet of Mazda's Skyactiv philosophy, that seems like a possibility.

We're still a long way from the new Mazdaspeed3's debut, and a lot can change between now and then. What do you think - does a Mazdaspeed3 work without a turbo? Would you buy one with the more powerful alternatives available? Let us know in the comments.

      Its just a rumor to piss people off..
      • 1 Year Ago
      No it does not work. It must be competitive with the current competition by going full TURBO.
      • 1 Year Ago
      No more torque steer :(
        • 1 Year Ago
        No more speed. They won't make in naturally aspirated unless they can get at least 250HP out of it.
      • 1 Year Ago
      no turbo, no go.

      Worst news ever

      Unless they can drastically lower the weight, I don't see how a underpowered fwd hot hatch could compete.. The gti has that german niche going for it.. Speed3?not so much

      I own a 08 speed3. Even stock pulls on evos and sti's. The motor is strong other than the rods... They almost got it perfect. Switching to a cheap motor is asking for problems especially if they throw a turbo on it. Gen2 is a heavy hog. Just gotta shed weight fix the few minor fuel prolem and zzb issues. And throw wider tires all the way around along with a better gear box that has longer gears. And a 6th that is actually highway worthy. Lose the turbo lose the speed in the name just make it a mazda3 sport or something.

      Just a rumor. Not going to happen. Mazda has proved time and again they are smarter than that. Now i could see a model between a 3 and a speed3 with 200 hp for a small premium over the normal 185hp model

      Smart decision! Mazda speed proved to be king of forced induction and now it wants to be king of naturally aspiration. Since Honda is to stupid to bring a type R hatch Mazda might take that crown away from Honda as well as steal it's buyers that have no choice for a reliable 5 door hatch. ***Think about it no body builds a reliable hot hatch***. Reliable and functional. Mazda when can I sign up for one? No really I can afford one and I will wait for this.

      Please don't ruin a great design with a weak motor! If this crap happens my money goes elsewhere..

      I can see this strategy (regular NA engine with very high redline) working for a Miata, but not a Speed3. And if they did decide to go this route, it would make a lot more sense to use the 2.5L as the base, not the 2.0L.

        Yeah, they should be able to get close to 250 HP out of that. With the weight reduction, that should be very competitive.
          • 1 Year Ago
          @Bryan Pizzuti
          I highly doubt you'd get 250hp from the 2.5L, although the rod ratio is quite high it still has a 100mm stroke. Also all the skylactiv engines involve massive amounts of development work to get them to their current state of tune. I think a 15% power hike is feasible (probably requiring higher octane fuel) but a 35% jump is a complete engine redesign.
