Rank 9 centres the Mazda RX-7 Group B — the rotary-powered rally machine Mazda Rally Team Europe campaigned through the mid-1980s with Rothmans sponsorship and a lightweight coupe silhouette unlike anything else in the Group B field. The 13B twin-rotor engine traded piston conventions for high-revving response and compact packaging that the master plate's technical rotor drawing celebrates inside a green-orange hex frame. Top-down and side-profile illustrations show Rothmans blue-red stripe geometry, number 3 door roundels, auxiliary rally lights, and whale-tail rear spoiler detail the poster renders with workshop precision. At the height of Group B's horsepower arms race, the RX-7 represented Mazda's bet that rotary smoothness and low mass could compete on loose surfaces — a philosophy the STORY column narrates in enthusiast voice. Churn-collector layout pairs dual car illustrations with rotary engineering art exactly as the master PNG dictates.
