6: 2012 Scion IQ
The Scion brand went from being the poster child for the next generation of car customers to a dated relic in Toyota showrooms. How did the brand go from prominence to obscurity? It was cars like the Scion IQ which made no sense. The car shared its entire design with the Smart ForTwo, a car itself was not doing well on the market (via Auto Evolution).

The Scion IQ was one of the last cars to have a Scion badge on it. The car was far from the unique concept of the brand when it was first introduced. When the car hit the market, it didn’t offer anything unique and its compact size didn’t mesh with the average consumer.
