The 1975 Chevy Vega Cosworth. A marriage between GM's 1970s rear drive subcompact and the 4 cylinder dual cam 16 valve expertise of English engine constructor Cosworth. In 1975 32 out of the 33 starters in the Indy 500 used a Cosworth DFV V8.
    
  The Vega Cosworth never really lived up to expectations because of pollution controls, but an interesting curiosity today.

Rotaries were pretty strong on performance in the 1970-75 smog era.

Mazda had a *lot* of trouble making the rotary engine ready for "prime time"--they burned oil and they sucked gas, and sometimes they would backfire so badly every war veteran within ten blocks hit the dirt.
 
To Mazda's credit, they stuck with it, and replaced a sizable number of rotary engines under warranty, and BEYOND warranty, and I'm sure it cost them a pretty penny.
 
Eventually, in the early 1990s they developed that rotary engine into the rather magnificent Mazda RX 7 Twin Turbo, which was, and still is, a formidable sports car and very quick indeed.
