D4 is the name of a Ford Motor scalable vehicle architecture designed to underpin front-wheel drive and all-wheel drive mid-size crossover utility vehicles (CUV). It succeeds the D3 platform and is adaptable to various wheelbases, with a suspension system that can be modified for towing and/or off-road driving.
This platform is heavily derived from the Volvo P2 architecture, which underpinned the last-generation Volvo XC90 SUV and Volvo S80 sedan. The D4 platform was developed when Ford owned Volvo Cars.
This platform is currently in production for vehicles sold under the Ford nameplate worldwide. However, there are talks of phasing it out in favor of Ford’s scalable CD6 architecture. Here are the Ford and Lincoln vehicles currently sold in the U.S. and Canada that ride on the Ford CD4 platform:
|Type||Unibody welded steel|

|Suspension Type (front)||MacPherson strut|
|Suspension Type (rear)||Multi-link independent|
|Predecessor||Ford D3 / Volvo P2|

|2.3L EcoBoost I4||280 @ 5,600 rpm||310 @ 3,000 rpm||Six-speed automatic||Ford Explorer (fifth generation)|
|3.5L EcoBoost V6||365 @ 5,500 rpm||350 @ 3,500 rpm||Six-speed automatic||Ford Explorer (fifth generation) / Ford Flex / Lincoln MKT|

|3.7L Ti-VCT Cyclone V6||303 @ 6,500 rpm||278 @ 4,000 rpm||Six-speed automatic||Lincoln MKT|
While the Ford D4 platform is currently used for two vehicles within the Ford and Lincoln lineup, it will slowly be phased out and replaced by the scalable CD6 platform. As we write this, it is unclear if the Ford Flex or the Lincoln MKT will carry on beyond the 2020 model-year.
All Ford vehicles riding on the Ford D4 platform are currently on sale. However, Ford has not yet announced replacements for both the Flex and the Lincoln MKT.
