Not only the rotary, but the suspension engineering, that makes it handle BETTER than a Spirit-R and Type-RZ RX-7.
The body dynamics that stiffen everything up, even without the center pillar in the doors.
Howabout the multistage intake system that uses the variable effect of the vacuum the rotary produces to increase the horsepower?
Then, back to the heart and soul, the rotary. Cleaner, fuel efficient, and powerful, all thanks to the new multi-side-port design.
Having driven a tester in Laguna Seca last month, I can say this car is better in many ways than the 350Z, and the G35... Two other cars I think should be on that list (well the G35 at least!)... Interms of engineering and technical prowless, Mazda is where it's at.
Hum, I'll buy the RX-7 upgrade, then swap in a real rotary, the OS Wankel 0.303 cu in, 1.27 bhp(ps)/17,000 rpm, and 11.8 oz. a Power to weight ratio of 1:10 rivals the real RX-7 Type RZ. MMmmmm
This is just another example of the real trouble American companies are in. On PBS the other night, Frontline divoted a whole hour to the extreme mess than the accounting/stock/ceo situation is in... Basically, Stock options aren't reported. CEO gets huge stock options. CEO lies about company's value. Accountants lie for value too, as they have consulting contracts with the company. Truth is found out, company's stock plunges, accounting company shreds paper... pays off politicians to keep things status-quoe... cycle starts over again.
Very scarry.
There really isn't too much wrong with trial and error, unless you end up blowing your engine up!
I know a guy who makes headers for Miata... his first design attempt at the making the header was based on past experiences with headers on rotaries. He went with the first design, after he tried 10-20 other pipe configurations, based on other educated guesses. None of which provided the overall better improvement in the torque curve and horsepower band that the 1st design, based on the long lasting design for the rotary header, provided.
As for publically available CAE for engines... You'll never get designs directly out of the major automotive companies. most of the animations you see on the web now are based on taking an engine apart, measuring tollerances, and drawing them up in a CAD program.
The comparison between the assembly line, and software development is a very very poor one. A better comparison would be between the R&D process that goes on in the auto industry and software development.
That is: There are concepts that come out at trade shows, some are working, others are just ideas/smoke and mirrors. Then a timeline, a few years if not more, is put into place to turn the concept into a reality. The real product then goes through 6 or more months of testing, before the real product comes out. Once the product is out, changes take place on an annual time scale, and the R&D team begin to show their new concepts. The cycle goes on.
There are few software shops that take this approach, but their code/product is stable, and robust.
Problems with this, other companies go straight from smoke and mirrors to product in a few months, ie internet time. They don't allow real R&D to take place to make the product the best it can be, and cause other competitors to rush their product to market.
If we all slowed down, and were not rushed by marketing types, and could resist those who push for incomplete products to go to market, software quality would improve. However, the idea that it may improve to the point where point/click/drag/drop application development could be a possibility is false, since there will always be a need to do the thining intensive research before hand.

I'm doing my masters thesis on bluetooth ad hoc mobile routing, and one thing I can say is it is not easy to setup and maintain a routing structure. If you have a sparse distribution of nodes, you may run into connectivity problems, although the algorithms for routing become fast. If you have a dense dist, the routing becomes increasingly toughter, as you will have more pico-nets, gateways, clusterheads, and routing tables to deal with.
Scatternet formation has to be done with a distributed algorithm, since, at the start, no node knows where the others are. There are many more problems with a network like this, for information transmission, like latency, reformulation of the network when nodes move, or are turned on or off.
Now, if cell phone protocols were changed, ie, new cell phones were built to use ad-hoc networks, with cell towers as fixed access points and gateways, the idea will have a good future.
What Verisign did was fraud... Fraud, Fraud, Fraud! They sent out "Domain Name Renewal Notices" -- a bill, and it can be infered that it is expected for you to pay.
Take 5 minutes, right now, and fill out complaint forms on the following websites:
The Xircom springport for the visor is very, very buggy... the user interface to setup the SSID, DHCP, Ip, Routing, DNS, etc is all over the place. It took a good three hours to set the thing up correctly with linksys wireless router... then it actually crashed the router! no other 802.11 device could connect after getting a connection from the visor.
On another router that didn't crash, the palm OS would hang at random, or disconnect for no real reason.
Save your money if you have a visor, and are thinking about getting the xircom spring port 802.11 adapter.
You *REALLY* don't know a thing about engineering... Not stable?! common... moderators, this guy is trolling, pure FUD.. Who the hell gave him a moderation point?!
