Concept cars are staples at major auto shows, but the cars typically look much different if and when they make it to production. In many cases, that's a mistake. Here are 11 times when changing a concept car, or failing to put it into production at all, was a big mistake.
1973 Chevrolet AeroVette Concept
If one thing had changed back in the early 1970s, today's Corvette would be midengine.
In 1969, Zora Arkus-Duntov (the father of the Corvette) built the experimental XP-882, a midengine Corvette concept. Unfortunately, John DeLorean, then Chevrolet's general manager, put the project on hold. To blunt the media impact of Ford's introduction of the midengine Pantera, DeLorean authorized a refurbishment of the XP-882 in 1972. The car emerged as the XP-895, with its transverse V-8 replaced by a four-rotor Wankel engine producing 420 hp.
While GM scrapped its rotary development program in 1973, the idea of a midengine Corvette was well received. Nevertheless, the Corvette remained front-engine/rear-drive for cost reasons. Had the midengine XP concept made production, then Corvette today would be perceived as a more apt competitor to Ferrari and Porsche.
