The Chevrolet Corvair (1960-1969) beat the 911 to market with a rear-mounted flat-six, but Chevy's engineering gamble came with a steering behavior that made it genuinely dangerous in untrained hands. While Porsche refined the concept into something manageable, the Corvair became a cautionary tale about how good ideas can get weaponized by poor execution.

A restored 1967 Jensen FF prototype reminds us that while Audi was still drawing up the Quattro concept, Jensen had already figured out how to make four-wheel drive work on a performance car. The FF combined a Chrysler 440 V8 with Ferguson all-wheel-drive tech—not because it was trendy, but because the engineering demanded it. Seventy years later, clean examples remain criminally undervalued.
