Now tucked away in the GM Heritage Center, when the Chevrolet Mako Shark II or XP-830 in internal General Motors speak was unveiled at the 1965 New York International Auto Show it was acclaimed as a stylistic tour de force.
It also represented pure show car whimsy, as was to be expected from the firm’s styling chief, Bill Mitchell. Many design cues were subsequently incorporated into the C3-generation Corvette that entered production in 1968.
That wasn’t quite the end of the story, though.
The Mako Shark II later morphed into a different concept car, the Manta Ray, that emerged in 1969. While ostensibly similar, the front end now had a pronounced chin spoiler plus a bank of rectangular headlights shrouded in Perspex.
The end of the 1950s witnessed a seismic shift in racing car design, with mid- and rear-engined cars taking center stage.
Chevrolet, along with other General Motors divisions, eschewed official involvement in motorsport, but “Father of the Corvette” Zora Arkus-Duntov was a racer to the core.
The Le Mans veteran conceived the Chevrolet Experimental Research Vehicle as a technical exercise; one that would be used to evaluate: “ride and handling phenomena under the most realistic conditions.”
While outwardly it resembled a stylized version of comparable Formula 1 machinery such as the Cooper T60, it didn’t “make do” with a small four-cylinder unit. Instead, it was initially equipped with a special lightweight version of the 283 in Chevrolet small-block V-8. To this day it lives on, displayed by GM at the Renaissance Center, in Detroit.
