    I'm legit excited for this car. My only hope is that they somehow get it under 2,200 lbs. Sometimes I take my brother's BMW Z3 out for a session. At 2,900 lbs it's not exactly heavy, but the driving feel is strikingly slow and heavy compared to my 1,900 lb Spyder-- even a bone stock Spyder at 2,185 lbs still feels much more lively than any other car I've had the pleasure to drive. Lesson learned = light weight is best weight. I hope they style the ND far, far away from the NC though. That thing looks like an aborted whale.

    I've never been a huge fan of NCs looks wise but lowering them from stock height makes a huge improvement in their looks especially on the NC1s. NC2s and NC3s came from the factory a little lower than the earlier model.

    Boosting and blown engines will probably become a big topic on Miata forums.

    I am probably all wet, but even with the more rearward engine position, one additional (probably too expensive) change would have been so cool: a rear mounted transmission similar to the Corvette

    The shifter is probably the best thing on the whole damn car. I don't think I want a rear transmission with long linkages.

    Mazda has been able to distribute the weight properly in all generations of the car (adding a driver completes the package), so there wasn't really a need. Also, for a lot of reasons, it's better to have the engine/clutch/transmission in one assembly.

    The US model seems to be getting a retuned version of the 1.5L Skyactiv-G. That engine in Mazda's fwd cars makes 99-115whp depending on the variant. So 115-120whp is a safe bet. 30-35hp for drivetrain losses puts that at about 150whp which make sense for a high output but very green modern 1.5L. I wonder if the 2.0 block is the same family. If so, the hunt for crashes fwd 2.0L skyactiv-G cars starts the same week the ND hits our shop.

    FWIW, 110whp in a 2200lb Miata is fun, if not particularly fast. That's roughly equivalent to a base model NA6 with I/H/E and ECU; 2200lbs/112whp.

    Where did this info come from? I don't buy it at least not as the only engine and well, won't buy that car. Everything I've seen suggests a retuned 2.0 from the 3. Plus my insider says the ND will be the best performer yet. I honestly think that low of power would ensure no further generation of car.

    Edit: re-reading I see the whp vs hp numbers and they're a little closer to okay. I'm still hoping for 2.0.

    My guess: 2.0 only for the US; 1.5 and 2.0 for the rest of the world.

    I certainly hope it is a tuned version of the 2.0. That could mean 170hp, which translates to about 135whp. That will be a very quick little roadster.

    US will be 2.0L, otherwise sales will never make it into the double digits.

    That old red 1.6 sure was fun to drive.

    Looks like the US will be getting a 2.0 in the ND.

    Hope the weight claims still apply for the 2.0!

    First look at the next generation Miata, er..MX5 chassis. Several interesting details. The pic is a RHD chassis. The engine sits further back than the NA/NB, possibly even further back than the NC. This is a true front-mid engine. Electric power steering. Drive by wire throttle body visible on the LHD side, meaning the head flows the same direction as the NC, opposite to the NA/NB. That means that those long runners are not coated headers but probably a plastic intake manifold as is de rigeur. Difficult to get the scale but those runners are very long, well past 14" to valve seat. That means possibly 2nd order resonance tuning. I'm thinking it will be a variable runner length manifold. Still a clockwise engine rotation. The front spindles, control arms and rear spindles appear to be aluminum. Not enough resolution to determine cast or forged. The front spindles are hollow indicating they could be shared with an AWD/FWD platform. COP ignition. Variable intake and exhaust cam timing. The transmission bell housing is blurred in this press photo indicating either the spec will change or Mazda has something tricky to hide there. No dual clutch as it would be too expensive for a car at the SRP the ND will likely have, and there's a shift lever besides. What's comforting to this Miata enthusiast is the same basic architecture as the first Miata 25 years ago. They got it right and have't messed with it. No struts, no transverse engines, no messing with what works to save a few pennies.


    -SuperMiata
    Didn't the NA have basically the entire engine behind the front wheel centerline? (atleast Cylinder 1-4, maybe not the cam gears)...?
