20: Kia KCV-II
The Hyundai Santacruz is one of the hottest new pickup trucks on the market, but Kia had a similar concept 20 years ago. The Kia KCV-II was a concept car that was designed around the same styling as the Santacruz. With proportions that were similar to the Kia Sportage, the KCV-II was a notable mix of style and functionality. Unfortunately, back then drivers weren’t ready for a pickup truck that was crossover-based.

Hence the failure of the Ford Explorer Sport-Trac, another crossover-based truck from this period. This was a functioning concept vehicle with a 3.5-liter V-6 engine and a permanent all-wheel-drive system. The final must-have feature of the KCV-II were the scissor-doors, which built on the fad from this period.
