What specifications, resources, photos, or artistic impressions are
available for the next model Mazda MX-5 (also known as Miata in some
markets). My understanding is that it should be out 2005.

Hello.

As I'm sure you're aware, with a car that's two years away from
production, a lot of the information is speculative. Only people
inside Mazda would be certain of exact details, and, even then,
details would be subject to change.  Nonetheless, I have compiled the
best available information about the next Miata.

The single best source seems to be a Motortrend article from two
months ago:
Sketch Pad: 2006 Mazda Miata
How do you redesign a sports-car icon
http://www.motortrend.com/future/spied/112_0302_news_sketch/
Highlights of the next Miata:
"While the two-seat sportster will be only slightly larger than the
current model, there's speculation the Miata will share its platform
with the RX-8. More likely, the connection will be limited to some
component sharing."

"One unusual feature of the '06 Miata is the convertible roof, which,
we're told, is a manually raised and lowered metal top."

"Mazda also is rumored to be considering a new lightweight V-6 as an
option for the Miata"

"The front end of the new Miata retains the current car's flavor,
while it's growing in size slightly"

Also see Miata.net:

"...Miata will be riding on a longer wheelbase, and will measure in a
bit longer as well. Slightly roomier inside - occupants will find a
bit more headroom, legroom and even more cargo area in the trunk.
Sources tell us the standard engine will be a 1.8-liter VVT four, with
a possible rotary engine offered as an option. Enthusiasts are hoping
for a lightweight V6 option, but there is no indication that will
become a reality.
The new Miata is expected to be offered with ESP (Electronic Stability
Program), as well as bigger brakes and 4 airbags."

incorrectly predicting a new Miata this year (2003)]

Brilliant! Thanks guys.

Howdy buzzboy,

Hopefully this will add to juggler's answer.

The Detroit News Auto Insider has this, a "photo illustration"
and a little more at their website.
http://info.detnews.com/autosinsider/sneakpeek/index.cfm?myrec=79

"The next Miata, codenamed J04, is expected to arrive early
in 2005, but will likely be sold as an early 2006 model year
entry."

With a different photo illustration, here is the Bay Area Miata
Association (BAMA) website's information that seemed to be sourced
from Motor Trend.
http://bayareamiataassociation.com/newsletter/August2002.htm#2004MazdaMiata

"Although it was expected that the 2004 Miata (codename: J04)
would adopt the J62 platform, recent information indicates that
the Miata will instead be treated to a significant refreshening.
A move to the RX platform may now happen in 2006 with the
venerable roadster favoring a traditional four-cyclinder engine
over the unique rotary configuration."

Denco:
The Detroit News photo is the same one that I mentioned above:

Quite right juggler!

Apologies on the duplication of information.

Looking Forward, denco-ga

You can find those specs on http://www.miata.com. It will be the 2006 model year.
