Nissan Rotary Power! Whether a factory Nissan rotary engine, or a Mazda rota stuff into a Datsun 1200, excitement is sure to result.

Nissan's Own Rotary Engine

At the Tokyo Motor Show, October 19, 1972, Nissan exhibited a Datsun Sunny PB110 with a prototype Nissan twin-rotor wankel-type rotary engine.

This was during the height of the rotary-power frenzy. Wankel had the patent, and every one licensed it, from GM to Mercedes to Mazda, and also Nissan. Nissan's interest started in mid-1965

Here is a picture of the prototype being tested in a Datsun Sunny 1200 (B110) coupe:

End Of the Rotary Era

The wankel design has the benefit of small size, low weight, high power for the size, and smoothness of operation (they routinely rev to 9k rpm). So why did everyone except Mazda and some non-automakers stop making wankel-style rotaries? It appears to be because of a combination of factors (these are my opinions, not necessarily hard facts):

  • Perceived value: at first it seemed that the public would demand these engines, so every automaker figured they better get busy and offer one. The president of Mazda commented something like the following: after Mazda and NSU put these high-power engines into hundreds of thousands of subcompact cars, the economy-minded public
