The Ford D3 platform is an automobile platform assembled by Ford Motor Company. In production between the 2005 and 2019 model years, the D3 platform is the fifteenth generation of full-size cars produced by Ford in North America. Marking the adoption of unibody chassis construction, a transverse engine configuration, front-wheel drive, all-wheel drive, and the lack of a V8 engine, the D3 platform is derived from the 1998-2016 Volvo P2 architecture. Since 2008, the related D4 platform has served as a basis for crossover SUVs.

The Volvo P2 platform is a global full-size unibody automobile platform developed and produced by Volvo. It is designed for single wheelbases and is adaptable to front- or all wheel drive configurations. It was developed by the automaker before its 1999 acquisition by Ford Motor Company, and debuted with the 1998 Volvo S80.
