The Ford DEW platform (or DEW98) was Ford Motor Company's midsized rear-wheel drive automobile platform. The D/E nomenclature was meant to express an intermediate size between D- and E-class vehicles, while the W denoted a worldwide platform. The platform was developed by both Ford and Jaguar engineers, and debuted in the Lincoln LS sedan.^[1][2] Its de facto predecessor in Europe was the DE-1 platform which underpinned the 1985 Ford Scorpio, however this vehicle was cancelled in 1998 without a direct replacement as in the European market, buyers were increasingly turning away from executive class cars manufactured by mainstream manufacturers.

Ford's use of the platform ended in 2006, but Jaguar continued to use DEW98 after Jaguar was sold to Tata Motors in 2008, building the XF on it. Jaguar's use of the platform ended in 2015 with the introduction of the second-generation XF using the Jaguar Land Rover iQ[Al] (D7a) modular platform.^[3]
