15: Scion XD
The original Scion lineup became a sales success for Toyota. When it came time to redesign the cars, the next models weren’t so well received. The XD built on the original product that was the XB, which in itself was never a flagship seller for Scion. The XD was seen as pretty bland and the car was a lot smaller than a comparable Honda Fit. Nevertheless, the model was still marketed as an important part of the Scion line until the brand disband (via Auto Evolution).
There wasn’t much to like about the XD, which is one of the reasons that it never caught on with consumers. Toyota had hoped to keep the momentum of the Scion brand going but unfortunately, it fell on deaf ears. The Scion XD never seemed to catch on with consumers.
