Ford D4 Platform
D4 is the name of a Ford Motor Company vehicle architecture designed to underpin full-size crossover SUVs such as the Ford Explorer, Lincoln MKT and Ford Flex.
The D4 platform is the crossover variant of Ford’s D3 unibody platform, and is not considered to be a direct replacement for any one existing FoMoCo platform.
The D4 platform is a revision of the D3 platform for crossover utility vehicles, often called high-roof derivatives. The architecture is adaptable to various wheelbases, while the suspension system is modified for towing and off-road driving.
Both the D4 and D3 platforms are derived from the Volvo P2 architecture, which developed from the time when Ford owned Volvo Cars.
In the D4 platform, the engine is positioned transversely (east-west) under the hood. Front-wheel-drive is standard, while all-wheel-drive based on a Haldex system (shared with the Volvo S80 and XC90) is available as an option.
