Just wanted to see what most people thought about the digital speedometer that seemingly will make it's way to the production model.
From interior shots, the instrument cluster includes a large, center-mounted tachometer. I love this setup; it reminds me of my '94 RX-7. Nevertheless, I'm a little wary of the digital speed readout in the bottom left corner of the tach. Here's a reminder for everyone:
Some of us might remember digital speedometers as a novelty in the 80's; a symbol of how "high-tech" the car was (T-birds, Cadillacs, even some Corvettes if I remember correctly). Did Mazda forget how annoying these digital speedometers were? One second you're cruising at 75, slow down, and then suddenly the car reads 45. What happened to the thirty miles in between? No digital readout clicking away numbers can compare to the pure joy of seeing a needle swing from left to right as you pass 40, 60, 80, 100....mph. Besides, the rate of change on the needle itself (velocity) gives you an indication of acceleration. Watching a number go from 46 to, let's say, 66 in one second is hardly as satisfying.
Hopefully, enough people know what I'm talking about. Of course, differing opinions are always welcome. Post your thoughts please.

I think digital speedo's have come a long way lately.
Personally, I wasn't a fan of them, either. However, recently I've ridden a couple of people's motorcycles which have digital speedo's (my bike's is analog), and it was nicely done. I have to say, I really liked it.
So long as there's an analog Tach, a digital speedo is fine by me. Just realize that technology has come a long way in the past 15 years.
I was hoping that digital speedometers went out with Knight Rider. I have driven several cars with them and I have hated them all. I'm glad that most foreign manufactures have stayed out of the digital speedometer game for the most part. You normally see them on soft American cars marketed at soft middle-aged women. Yeah, I remember them on the Vette and other sportier cars, but they were a mistake.
I remember taking an instrumentation course back in school where the pros and cons of digital vs. analog were discussed ad nausium. Digital instruments are great for accurately displaying precise measurements that do not change rapidly. Analog gauges are much better for displaying data where not only the current results are important, but equally as important is the direction and rate of change. Position, direction of change, and rate of change are very important on automobile speedometers and analog gauges are inherently much better at displaying those things.
This is the same reason why electricians, electronics technicians, and engineers have to use analog Ammeters and Voltage meters when troubleshooting a circuit in which a current or voltage spike is tripping breakers or causing other damage. You can see the spike on an analog meter and you would never be able to see it on a digital multimeter. DMMís display great accurate information if the data isnít changing, but if it is changing, the display canít keep up with the results.
Please Mazda, tell me that the digital speedometer on the RX-8 dashboard was just a quick eye-grabbing thing they through together for the demo car. Please put a real speedometer on the production car, a nice big one, right next to the tach.
Count me as one of those who don't like digital speedo's, but the technology has progressed pretty far. I think new digital readouts do a much better job tracking rate of change than they used to. I would still prefer an analog speedo, but the presence of a digital speedo won't turn me away.
The attached image above does show room for a voltmeter. Can we get full instumentation?
BTW, I currently own a GM product that came from the factory with a 5 speed manual, and no tach on the dash. What the hell were they thinking?

I agree. As long as the tach is analog, I donít mind the digital speedo. For performance driving, I usually concentrate on the tach anyway, and it seems that they understood that by making a the tach more the focus and the speedo secondary.
As I read this thread it made me think about my recent speedo purchase. I'm an avid performance boater and as such realize that allot of boaters are also 'ench racers'. Every guy I know with a jet boat runs at least 80 and I don't think a v-drive was made that turns sub 100 passes. The accuracy of marine speedos is pitiful. A pitot tube hanging off the transom approx. 2-3 inches below the hull getting stuffed with sand, silt, air and whatever else is suspended in the water your running in. It's no wonder they're inaccurate. I just purchased and installed a GPS speedo for one of my boats and while I didn't pick up any speed on the top end it was far more accurate on the low end. And because of the memory feture the next time someone disputes the claims of my twin turbos I can simply stroll over and mash the recall button.
Although there is something exhilerating about the clockwise sweep of the arm. Not to mention being able to catch it out of the corner of your eye and having an idea of your speed.

I kinda like the digital, for track use since you can instantly glance and know your speed instead of looking at the needle then, looking for the tic mark and then the closest number, which is good since all you'd look at is the tach, and how much space is left till redline, then maybe check the speed. Digital would make it easier for knowing just how fast you can take a particular turn.
However, on a normal driving basis, the flickering of the numbers would drive me pretty crazy. (in a bad way)
i think that just saving the stupid options for luxo-mobiles should be a priority, and just keep the digital metres in the prototype show model... EXCEPT FOR THAT DIGITAL FUEL METRE!! OH CRAP, YA!! awesome suggestion Strider...
i don't really like the digital tach anymore, since i have one on my daily driver. The car has been sitting in the back yard for like 5 years, before i got it up and running again, and at times the tach will disappear on me, and i can't even tell how fast im going. Well i can, just not to the exact KM.
I prefer with the analog, but really i won't care as long as i have an rx8
Originally posted by twenty seven i think the 92-96 prelude is reason enough we should stick to analog. i hate digital speedos, too hard for me to judge my speed by using peripheral vision.
The 4th gen Prelude has analog speedo/tach gauges... What are you talking about?
I also prefer analog over digital but as long as the tach is analog I'm happy. I don't really care for the speedo.. Don't look at it much anyway. I usually go by the rpms/gear and know roughly what speed I'm at. As for track/auto-x I might as well not have a speedo at all..
I LOVE the digital speedo... you need the Tacho to be analogue I grant you... but the speedo is to tell you how fast you're going, and you can get that more accurately from a digital one.
If you need to see how fast it's changing, look at the tacho or feel the g force. I prefer to glance down at the digital number and then back to the road while my brain decodes the number... rather than trying to peer at a dial to see what the exact speed is.
Yes, I've had digital speedo's before, and infact I've had digital (Sorta) tacho's before... the tacho was a LCD bar chart in the layout of the power curve... it was actually pretty cool.
"Who is Seg Fault and what is he doing with Kernel Space?"
I have no problem with a digital speedo. In fact, if it means that I can get some real secondary gauges (oil temp, pressure, water temp, etc.) instead of idiot lights, I would celebrate the use of the digital speedo.
Some people have mentioned the fact that it is easier to see changes and movement in an analog gauge. This is very correct, which is why an analog tach is preferable. The tach changes quickly, and you need to follow it at times.
But a speedometer is rarely a gauge that moves quickly. And frankly, when it is moving quickly (under heavy acceleration or braking), there are many other things that you need to be watching instead of the speedo. You are normally checking a speedo when it is steady, and therefore easy to read.
In personal experience, I had a Pontiac GTP with the Heads Up Display. It was a digital speedo, of course, and it was very easy to follow. In fact, I found it easier to follow than the analog speedo gauge in the instrument panel below. I don't see the digital speedo in the pictured instrument panel being any different for me.
