As an enthusiast who follows the car industry, I see some companies come up with with ideas that are fanciful and fantastical, but that never quite make it in the real world. Like Mr. Iaccoca and his failed experiment, the DeLorean.

However, some ideas are so simple, so far-reaching in their ability to solve problems, it's a wonder why the manufacturers don't see and implement them.

Here's my first in a series I call Automotive No-Brainers.

MX-5 Miata + Rotary + Roof = Next RX-7


Rumors have been swirling about a new RX-7 ever since the RX-8 was put out to pasture. Mazda, a small and newly independent car company isn't exactly flush with cash once the Yen fluctuations are taken into account. Mazda has been trying to find a business case for the next RX-7 and the next rotary engine going in it.


Mazda has also been trying to improve the MX-5 Miata's business case by collaborating with Alfa Romeo on the next one.

So why not kill two birds with one stone here? The Miata's bespoke platform needs volume to cut costs. Why tool a whole new, different platform for the next RX-7, when all the Miata would need to become the next RX-7 is a hard roof and a rotary?


Every few years or so, Mazda toys with the idea of making a Miata coupe.

Putting the next rotary in a Miata coupe would keep the RX-7's costs low, much like the original's was back in 1978. Its low purchase price would make it a deadly rival to cars like the BRZ/FR-S, and a deadlier rival to the much more expensive 370Z, to boot. And it would add economies of scale for the Miata platform, itself.


So why hasn't it been done yet? Why can't Mazda see the simple, inherent logic in this? Am I missing something?
