It's another car for me and you; another car we didn't produce. Steve Finkbuilt hipped us to the fact that 38 years ago, in a year that saw the births of such luminaries as John Reis of Rocket From the Crypt and our very own Postfather, General Motors cooked up a hybrid car. According to a Popular Science article from the time, "With all-independent suspension, front-wheel drive, a low center of gravity, and wide track (49 inches), the XP883 should be great fun to drive. But whether, and when, you'll drive one is something that the GM chiefs haven't made up their minds about yet." Instead, we got the Vega.
