From the Archive: Mazda's first-generation RX-7 sports car with its new 13B rotary engine.
With a complaint list so short, it's clear to us that the RX-7 GSL-SE is the best and sportiest RX-7 ever offered to the American driver. At a base price of $15,095, it's also the most expensive. That's a full two grand more than a regular GSL, and quite a sum for a car that made its reputation on exceptional affordability; at this RX-7's price level, there are now Supras, Starions, 300ZXs, and well-equipped V-8 Mustangs and Camaros to choose from.
Oil is injected into the intake-manifold plenum in conventional Mazda fashion, but the 13B receives additional apex-seal lubrication from oil injected directly into the trochoid chambers. The rotor-housing surfaces are chrome-plated, like the 12A's, but have a harder finish and improved porosity for better oil retention, giving the 13B durability to match its muscle. —"I felt a genuine surprise when I first saw a running prototype of the rotary engine in 1961.
The "hard way" is an apt description of Yamamoto's early career. He graduated from Japan's Imperial University in 1944, with a degree in mechanical engineering, only to be snapped up by the navy to supervise the production of kamikaze aircraft. After World War II, he returned to his hometown, Hiroshima, and found most of it leveled by the atomic bomb.
"In the beginning, we experienced lots of difficulties. Some were technical, others were not. Since we had announced to the world that we were undertaking rotary-engine development with the intention of building and selling engines, many people, both inside and outside the company, voiced strong criticism before they saw any results. Therefore, whenever the young engineers were discouraged by technical problems, they were also disappointed by outside criticism.
