Report: Mazda RX-7 Returns for 2017 with 450-hp Turbo Rotary

[Howard]

That was in response to your example of an RX-7 with an LS engine. Of course there are ICE cars with excellent balance. I don't think anyone claimed that a Rotary was the only way to achieve that.

While the car did indeed gain some mass, the balance was not significantly made worse. Also, mass (weight) in itself is an intangible just like HP/L, though perhaps less so. Figures like acceleration, overall fuel efficiency, lateral acceleration, braking, etc. are what is directly perceptible to the driver. I guess in this type of situation, you would give up some lightness to increase your potential power output (or reliability, etc).

What remarks? I mentioned the statistic, and that it was interesting. Nowhere did I, or anyone else, say anything different.

That displacement is proportional to size and mass, which clearly it isn't.

Beats me. But if someone were to design a unique/fun 2-stroke engine, I would certainly take interest.

Maybe my point wasn't made clear. There are lots of types of engines out there, and only a few types are undergoing any sort of real development. Those engines that have been deemed unworthy of further time and money, were deemed so almost always for good reasons. The rotary may well end up a classic example of this.

You might think it's "stupid", but that doesn't mean everyone else does... Or should.

Mazda's CEO thinks it's stupid right now. His opinion definitely trumps mine and yours.

Entertaining read, if nothing else:

Is that after he added weight to balance it? He doesn't really to into detail other than saying "So I was down in Torrance, (West Side Alignment) getting my car corner weighted and balanced..."

That displacement is proportional to size and mass, which clearly it isn't.

Seriously? Did you miss the point, in that same paragraph, where I said "Of course, not in all cases, but certainly in this one."?

Maybe it will. They haven't made one in four years, so it's certainly possible. But if the rumors are true that they are developing a new Rotary, then it's certainly not true.

Again, if the rumors are true, and a new RX comes out in a couple of years...

No idea. Peer-reviewed scientific papers, those posts aren't. I didn't see anything about it, so maybe, maybe not.

Seriously? Did you miss the point, in that same paragraph, where I said "Of course, not in all cases, but certainly in this one."?

I saw it but initially deigned not to reply in full.

Maybe it will. They haven't made one in four years, so it's certainly possible. But if the rumors are true that they are developing a new Rotary, then it's certainly not true.

We'll see.
