 The fourth-generation Taurus would be the final derived from the original 1986 model line.In 2004 and 2005, as part of its effort to increase the use of globally sourced platforms, Ford introduced the Volvo-developed Five Hundred and Mazda-developed Fusion to fill the slot of the Taurus in the Ford line (for non-fleet buyers, the Five Hundred also served as a replacement for the Crown Victoria).The Taurus nameplate returned in 2008, as Ford renamed the Five Hundred to increase its sales.
