What about the Mazda RX7 (was it RX, or XZ or something!?) it ha (or had) a
radial engine!! Looked like the drum out of a washing machine!

RX7 is correct...that engine was called a 'rotary' type. More
correctly it's called a 'Wankel', after it's designer (German?).

Pretty good engine, hard on fuel, very smooth operating, operates
at quite high speed (red-line is 7,000 in the RX7). Very flat
torque line (curve). I had two of them, 1983 and 85 (new). They
developed 110 HP from only 1198 CC displacement.
