Looking at recent spy shots of the fourth-generation Mazda Miata, it's obvious this sporty little roadster will grow in size compared to the current model, but it's also going on a diet. At the Tokyo Motor Show, Auto Motor und Sport sat down with Mazda executive Kiyoshi Fujiwara, who gave a little more insight into the Miata's redesign.

Fujiwara said that they're aiming for a curb weight of a tonne (metric ton), which is 1,000 kilograms or right around 2,200 pounds, for the next-generation Miata. This would make the roadster at least 300 pounds lighter than the current NC Miata, but still about 200 pounds heavier than the original NA.

There is no indication as to how Mazda will go about removing that much weight from the bigger car, but with as popular as the power retractable hard top (PHRT) model is on the current car, the new Miata may ditch this feature to lose its weight. Improving the power-to-weight ratio appears to be a key goal of the Mazda team, so we also wouldn't be surprised to see a more powerful engine underneath the longer hood.

      "...but still about 200 pounds heavier than the original NA" Considering how much more safety equipment they're required to have compared to 1990, only an extra 200 lbs is a great acheivement!

      In 1989, I worked for FCB/LA, Mazda's U.S. ad agency. I got to drive the first pre-pro Miatas brought over for the auto shows. I worked auto show PR and got to see crazy 'murcans rush the Japanese Miata "chaperones" (most of whom didn't speak english), waiving their checkbooks and hollering, "Me buy this NOW!" In 1990 and 1991, I got to write all the national advertising for the glorious little car. It was the highlight of my career. Fast forward to May 2013. I could never get myself to spend the money on a "toy" car, so I never owned a Miata. That didn't stop me from shopping them on craigslist, and one day, a 2002 LS BRG (yeah, it's really Emerald Mica) over tan popped up on the screen. The guy who was selling it had a garage floor you could eat off of, and my golf bag AND pull cart fit in the trunk. A week later it was in my garage, and I haven't stopped smiling. Thank you, Mazda for the great experiences of both marketing and owning this landmark car!

        Golf bag AND pull cart! How did you do that? Weekend golf bag? My pull cart does not even fit in the trunk of a 2013 Ford Escape. I seriously need to update my golf bag and push cart.

          I've seen some very compact golf bags, and I wouldn't be surprised if they fit in the boot of the MX5.

      Huge, huge mistake if they drop the power retractable top. We can't GIVE away a soft top MX-5. Everyone wants the power top. I don't care how much weight they can save, buyers don't quiz me on how much the car weighs. They drive it, love it and buy it - and they want a damn power hardtop.

        Yup, power hardtop all the way. Best of both worlds and no worries about asshats knifing the soft top. They are neither cheap or easy to replace.

        To be fair, no one will quiz you on the center of gravity of a vehicle either, but it significantly contributes to how it drives, which equate to favorable reviews, which drives customers to check the car out.

          Don't get me wrong. I'm a huge MX-5 fan and have been since the car debuted. I was happy to learn it was going on a diet, but we sell a lot of MX-5s to folks who have owned them already and once someone has owned a PRHT they aren't going to be very pleased to give it up.

        The power hard top is in fact, wonderful but I am REALLY close to being too tall for the existing model and the soft top adds just enough headroom so I don't touch. This is the only motivation for the soft top I see.

      1990 Miata weighed 2105 (or 2116) lbs. at it's lightest depending on where you read. Careful not to drop 100 lbs. when those lbs. are so hard fought.

        And the lightest version was a car with wind-up windows, no power steering, and no AC.

          That was the car I drove in HS...lots of fun (though ABS would have been a welcome addition).

      LOL 1900 pound original miata? on what planet are you from? I had a no option base model 90 and it was a over 2100 lbs even stripped in race trim, they are over 2000 lbs.

        @ELG
        Well then that would make the new Miata the same weight as the original, which is quite a feat considering it'll be quite a bit larger and have more power. Sounds great to me!

      If only they put a Renesis 16x inside her, that would drop the weight and you could keep the hard top, with all that free revving rotary power!!

        I always wondered why a rotary was never even an option for the MX5. They are both iconic to Mazda and both niche.

          My guess is they didn't want to steal any of the RX-7's or RX-8's thunder.

      when Mazda was developing the 2nd Generation Rx7 they had a program where they got everyone involved with the new design...all the engineers, etc to think of a way to drop off a few grams of weight. this lead to it having an aluminum jack and an aluminum hub on the spare tire, among other things. They continued this with the 3rd gen (lead to an aluminum hood) I do not think they will have any problems meeting this weight requirement.

      They should do a MRHT (Manual Retractable Hardtop). Get the security and comfort of a hardtop without the weight and complexity of the motor/gears etc.

      "but with as popular as the power retractable hard top (PHRT) model is on the current car, the new Miata may ditch this feature to lose its weight." I can't see Mazda dropping this if it's presumably popular.

        Maybe it's just me, but I don't see the point in having a retractable hard top on a car like this. When it comes to little two seat roadsters, I say the simpler they are the better. I would take a rag top any day of the week on a car in this segment. Not only do I think they look better, but they are also cheaper, lighter, and less complex.

          Maybe its just me, but I don't see the point of having a convertible top on a car like this. When it comes to little two seat roadsters, I say the simpler they are the better. I would take a fixed roof any day of the week on a car in this segment. Not only do I think they look better, but they are also cheaper, lighter, and less complex.

          You don't see the point of a popular option? It's simple--not everyone is like you and don't like/dislike the same things you do. You know, "choice" and all.

      This is one of my favorite cars because of it's weight. Years ago, my parents owned an early model. I loved to borrow it. Lightness > Power. I do want to know how they are doing it, especially as crash tests are getting more difficult. They are probably using higher strength steel. Also, a longer wheelbase will give the steel a greater distance to crumple, and therefore lower peak acceleration during impact. I hope this diet doesn't come with a big power cut. I also hope that there is still enough room for a small block V8.
