2010 Mazdaspeed3 – Click above for high-res image gallery

File this in the drawer labeled "Only Remotely," but Mazda U.S. VP of product development Robert Davis allowed that the company is considering a diesel engine for the next Mazdaspeed3. Based on the report in Car and Driver, it looks like that's as far as this has gotten: a diesel is on the table. Beyond that, none of the 'pros' mentioned seem to make a case for it, and the 'cons' make a case against it.

The idea is made possible by the fact that whippersnappers getting into a Mazdaspeed3 aren't against diesel engines, being more familiar with modern clean diesels than the particulate monsters of yore. But if Mazda boosted its diesel Sky engine for the purpose of being a high performance engine, the frugality benefits of the engine would be erased. Then there's that whole issue of additional heaps of diesel torque, and the additional heaps of torque steer that Mazda would have to engineer out of the car.

So it is perhaps best to take from this that a diesel engine for the next Mazdaspeed3 is a distant option, which could be seen as another crack in the wall. And while "Only Remotely" doesn't mean impossible, we wouldn't place any wagers on such a thing happening this next go-round.

      Question, Torque Steer is constantly a criticism of the Mazdaspeed3. Why would Mazda use a engine, that is notorious for Torque????

      We would have forgotten entirely about the smelly, slow diesels of yore if automotive publications would cease bringing them up...
      • 4 Years Ago
      When I was at the DC auto show last year the guys at Mazda seemed very excited about using a diesel.
      • 4 Years Ago
      I think a diesel would be great but not for the speed 3. vW has the right idea with the tdi although we get the garbage motor. The GTd in Germany has 170 hp. How about the Speed-D (speedy).

      But the Mazdaspeed 3 needs to be a gas turbo.

      Don't 'cons' make a case against it?
        • 4 Years Ago
        Sorry, meant to say:

        Don't 'cons' usually make a case against something?
      • 4 Years Ago
      Doubtful. Maybe the regular 3 might get a Diesel but not the Speed3.
      • 4 Years Ago
      Very few diesel cars available in North America at the moment, so any diesel cars, particularly efficient subcompacts/compacts, would be welcomed gladly.
        • 4 Years Ago
        Uhh... I'm not sure this would fall into the fuel efficient category. Its like the Peugeot 908 or Audi R15. Yeah, its better than the petrol powered cars in its class but it won't exactly sip its fuel.
        • 4 Years Ago
        Yes, please!
        • 4 Years Ago
        Alex - Wouldn't this go up against the GTD from VW? I mean, not that we get that one either, but 170-200hp diesel in something like the Mazdaspeed3 might be really, really cool.

      Bunkum.

      And the stuff about more torque meaning more torque steer?

      Torque steer comes from torque going to the wheels, not torque at the shaft. The torque at wheels is generally higher on gas engines than it is on Diesel engines.

      Note that torque at the wheels directly translates to acceleration and you will note that gas engines generally accelerate faster than Diesels. Now, if Mazda were to bump up the performance on their Diesel engine to match their gas engines, yes, it would have more torque steer than their regular Diesel, but it would have no more than their gas engines because the performance is the same.

      This story is either an attempt by Mazda to rub some PR off their Mazdaspeed 3 onto coming Diesel offerings or it's a fanboy made up story.

      It doesn't seem like a turbo diesel is a good fit for a true performance car, at least not to those that are used to ever-higher revving gas engines. Obviously it can be done, as Audi showed us, but it would have an entirely different character and gearing to go with it. What's the fastest that diesel combustion can actually occur, somewhere around 5000 RPM?
      • 4 Years Ago
      Mazda, why don't you start with a facelift instead.
        • 4 Years Ago
        Because sales of the Mazda3 are very strong already.

        Just because you don't like it doesn't mean others don't.

      "But if Mazda boosted its diesel Sky engine for the purpose of being a high performance engine, the frugality benefits of the engine would be erased."

      I'm sure a few people would suffer temporary blindness in order to possess such a vehicle.

      But "erased"? Purest, unadulterated Bee-Ess. Just "put on hold" for those moments when your right foot turns to lead. I'm sure you could still get 50+ mpg out of a diesel 3. Ask Top Gear...
      • 4 Years Ago
      C'mon Mazda. Build it, and you'll have me paying for another '3 for the next couple of years.
