I think it was the RX-7.
Yes.
The RX7 is a hold-over, if I remember correctly...
I remember when Mazda hit the market. I was pretty young, maybe 8 or 9? Their commercials made a big deal that Mazda did NOT use piston engines. (boing! boing! boing! vs. hmmmmmmmm...)
Over the years, and dealing with (and eventually fixing) inherent problems in the Wankel, they went to reciprocating engines in most of their fleet, and only kept the rotary for the RX7. I don’t think the RX7 was available at first...
