I'm not discounting anyone's opinions. I'm saying that you need to consider what the market wants vs what you want. Did I ever say I don't want a higher-powered Miata? Of course I would, that's why I have a turbo Miata. What I do understand and appreciate is that I am in the minority on that. It's very easy to forget that the small (and it is quite small) group of enthusiasts in a place like ATG isn't the whole auto market. ATG is full of people with very, very fast cars, and many people here forget that the rest of the country doesn't have the same hunger for horse-ponies.
About 5400 MSMs were ever made. Yes, they were desired, but out of the 1M or so Miatas ever made they were a VERY small fraction. I would argue that the reason some, or many, of these cars sold wasn't the extra power, but the limited-edition appeal as well as the stunning colors offered only on the MSM.
First of all, I absolutely agree with the first paragraph above. I often get over excited about something as an enthusiast, but I do realize that I'm in the minority.
In regards to the second paragraph I agree and disagree (at least to some extent). I agree that there were other reasons to buy the MSM besides the power (colors, it being a limited edition, etc...). However, I would think that if a similar "performance" package could be offered on the new car, it would have a decent take rate (and might help with media buz).
Just as an example (and only because I own one and know enough about recent orders to use this as an example): look at how many people bought the Z51 package on the new stingray. Allocation for the Z51 was constrained to 50% at launch and still is... and they sold every Z51 that was allocated in 14 and there was definitely a longer wait (in excess of 2-3 months additional to order at one of the largest dealers in the country) when I purchased my 15 (granted that was in the beginning of the year). Now the corvette may not be a direct analogue to the miata, but they are similar in the fact that they are both generally not purchased as primary vehicles and typically have an older audience (and I should note that the Z51 package doesn't add any power... unless you count the small amount added by the performance exhaust option which was bundled with the 15 MY Z51 cars and can be optioned on non Z51 cars too).
I think things like "performance packs," though they may have a low take rate in many cases, do add something to the brand. If the manufacturer can figure out how to make them a "great deal," even if that means not making a lot of additional profit, it can bring people (and attention) into the brand. Also, clever bundling (i.e. MSM), can help keep profits up.
You bring up some valid points.
A 100% total de-compounding coefficient is typical of most sprung masses. Note that I referenced rotating and rotating + unsprung masses, which have a larger effect than other masses. I picked these systems as a dramatic example of my point. I also made the implicit assumption that performance was at least maintained, if not improved, as that was the context of the discussion.
To your point (2) mass de-compounding can only be brought to full effect at the start of a design process. As the vehicle progresses through its development cycle the ability to change the mass is reduced. It is generally assumed that one is talking about the very start of the development cycle when talking about mass de-compounding.
I figured that you were adding a bit more because of the rotational and unsprung aspects. Thanks for the info.
Again, I'm not saying anyone isn't entitled to their opinion. I'm sure that some people would find a higher-powered Miata more fun. What I am really frustrated with is people always saying "the Miata needs to have more power" when there is a long history of success without it and without consideration for the numerous side-effects of adding more power. The Miata has so many stellar qualities that are dismissed in the light of acceleration performance that isn't absurd.
My main gripe about the car is that I feel it's underpowered for something I would want to buy new. As I said above, I agree with you that it's because I'm an enthusiast and probably do not represent the market perfectly. That doesn't change the fact that the car has many awesome qualities. Unfortunately, it would stop me from buying it new. It would not stop me from buying one second hand in a few years and slapping some FI on it (though I'm pretty sure the new skyactive engine would stop me from doing that and probably push me towards an older one).
I agree that the Miata will need to appeal to the younger generation, which is why it's styling has gotten more aggressive and it's performance numbers have improved. But soon the 60 y/os won't be buying Miatas to relive old British roadsters, they'll be buying them to relive the NA Miatas of their 20-something years. It worked for the Mustang, right? :awe:
Lol that is a good point. Also I think the new styling is on point. TBH I kinda hate the way almost all previous gen miatas look. I don't want my car to look happy! That being said, I've always given them a pass on looks because of everything else that they are.
Another thing that irks me about all of these 'desired changes' to the Miata is that they just turn the Miata into another car on the market. I want a coupe Miata! That's an FRS. I want more power! That's a 370Z. The way I see it the Miata has a unique combination of attributes that, if changed, would turn it into some other car already in the market, which I don't think would be a great call.
Agreed... at least mostly. I like the idea of a removable hard top that can be purchased at a dealer at the same time as (or after) you buy the car. I don't think they need a dedicated coupe or whatnot. Shit I don't think they need a power folding hard top. Cloth top for warm areas / times of the year. Removable hard top for those who want to drive them in colder months (sorta like a jeep).
BRZ/FRS would be a great coupe alternative.
The 370Z is a great example of power not being everything. I wouldn't consider that as an alternative to the miata / BRZ (I'm just not a fan of that car really). I do like the exhaust note though.... and I think it looks pretty good.... and at least it's cheaper now than it was a few years ago. I would definitely take a Hi-Po (N/A and still sub 200hp) version of the new miata over the 370z all day every day.
Edit: this is one of the few non-proprietary papers on mass de-compounding:
http://msl.mit.edu/theses/Bjelkengren_C-thesis.pdf it is an interesting approach, but has some flaws.
Thanks for the info JCH13. I actually read that thesis about a month ago when I had a similar debate with a coworker and good friend who is also a car enthusiast (not about the miata but about weight reduction in general). Really, this is the reason I knew what you were talking about (lol). Conceptually it's pretty easy to understand; however, I imagine that it's a bitch to actually do the engineering work and realize the gains in a normal production cycle. I'm sure the modeling work that you are doing will eventually make it easier for whatever manufacturer you are working for (just thinking about all the variables makes my head hurt).
I will say that it has been fun debating you. Please don't take anything that I said as a personal attack, it surely is not. I do value your opinion and experience quite a bit.
Edit: looks like they are at least thinking about it:
