I haven't had time to read it yet, but I'm not holding out much hope - they are showing the old yellow car in the article!

I hate to say it but it looks like they were driving the concept. The seats, design of the front and the led lights on the sideview mirrors just scream concept. On positive note the car sounds like itsvery refined and quiet which is a sign that some of us can mod for more performance at the cost of a loud sounding engine by adding free intakes and exhaust systems

"At high revs, attained with eerie ease it must be noted, the only thing that deters you from revving past the red line and up to 9000 rpm and beyond is an annoying - but necessary - ringing sound..." :D

i took some time yesterday and posted the newer pics (turn signals, bigger ducts etc.) over at mazdarotaryclub.com so they could see the difference. most of the posts so far have been about the plastic over the engine

Some good hard data can be found in this article. Even though they show the old car, it sounds like what they drove was the new one. Excellent find. Most note-worthy:
Turns lock-to-lock: 3.0 . That's a bit high, I would have prefered 2.5-2.7 turns. Oh well, BMW uses 3.4 turns lock-to-lock, and it's steering feel plenty precise, so I am probably nit-picking. At least @3.0 turns lock-to-lock it won't feel as darty as my current car on the freeway.
Weight: 1300 kg estimated (2860 lb.) If this is correct, the car has lost a bit of weight (130 lb.)! Always good news!
Fuel economy, combined driving: 28-30 MPG. Methinks this is a little overly optimistic. :D One can hope though. I wonder where they got this number from?
It does say at the bottom of the data box is small print "All figures manufacturer's claims" so either Mazda has come out with some crazy breakthrough or its a misprint.
Brakes: 4 piston calipers, ventilated discs, 323 mm front, 302 mm rear
The link to the third page is wrong. Use this link: http://www.mazdarotaryclub.com/forum...autocar_03.JPG
Interestingly, this article also suggests the rear seat is cramped for full-size adults.
"Steering wheel adjusts in both planes" - does this mean it tilts and telescopes?
Power steering assist is electric, as in the S2000! Didn't know they were going to forego the usual hydraulic pump! (Maybe I missed that somehow over the past few months.) The author liked the steering feel a lot.
I suggest making this thread a sticky.

Besides 98% of the time I'll be driving alone, and as long as people can come with me I really don't care much for their comfort :P

I guess I'm just in a pessemistic mood tonight, but in the article the author said that he kept swinging past the redline and as a result, the "rotor tip seals" broke. I know that he was probably really pushing the car to test its performance but isn't it still a bad sign that he managed to damage the engine in just 4 laps? Seeing as the peak horsepower of the car is way up in the high rev range wouldn't it be easy for anyone to fly past the redline? I know that if I do get this car, I'll probably never try to push it right to its limits but seeing as I could easily make a few mistakes, what are the chances of me damaging the engine?

It appears that the author who wrote the section:
"...and several times during my test drive the needle sailed past 9000 before my resolve and the engine's rotor tip seals broke."
really didn't know what he was talking about. Since the article is from Autocar UK, it may be a slang or translation problem to the "English" that I understand. Does anyone from the UK understand what that means?
He clearly could not have broken the apex seals several times or even once.

l sat in the toy yellow show car back in July and was real impressed by the leg room front and back, the way they appear to have achived is constucting very thin front seats.
Hope this helps.

English translation alert...
They guy meant that he got over 9000RPM several times before he chickened out because he was WORRIED that he MIGHT break somthing... It doesn't suggest that he DID brake somthing.... Infact it suggests that he had a good try and nothing did break.
Edit: - Didn't they say that the production version would redline at 9000 and the buzzer would be at 9500... I really doubt that they would let you take it anywhere near the speed that could hurt it... I'd guess that the buzzer also has a rev limit on it... or at least that there is a rev limit below 10K.

But many of the cars in the test were well over 3 turns lock-to-lock, so I'm not worried. Every recent review of the 8 that has been popping up raves about the steering feel.

Based on that, I'd guess that there is considerable room designed in above the redline, and brief or accidental excursions beyond the redline should not cause any damage.
