4: Ford Taurus X
Originally released as the Ford 500 in 2005, the Taurus X was an attempt by the automaker to reinvigorate a dead nameplate. Sales of the wagon weren’t doing what the executives had hoped for. Ford thought that by bringing back a trusted brand name like the Taurus it would somehow reinvigorate sales numbers (via Hot Cars).
Unfortunately, the Ford Taurus X never achieved any serious sales numbers either. The car was just another novelty item that Ford tried to have consumers latch onto. There were better offerings on the market, and they came with much better features and performance for the price.
