Chevrolet's Rear-Engine Flat-Six Was Porsche's Forgotten Predecessor
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.
The Corvair proves that being first means nothing if your suspension geometry wants to kill the driver—Porsche's engineering obsession made all the difference.
