The Ford D3 platform is an automotive platform used by Ford Motor Company for model years 2005–2019, as the fifteenth generation of full-size North American cars.
The platform used unibody chassis construction with a transverse V6 engine and either front -or all-wheel drive. The platform derived from the 1998–2016 Volvo P2 architecture, relating to a period when Ford owned Volvo as part of its Premier Automotive Group. From model year 2008 on, the related D4 platform served as a basis for crossover SUVs.
While the vehicles of the D3 platform were officially introduced as the replacement for the 1999–2007 D186 platform (Ford Taurus), in terms of market position and interior volume, they effectively superseded the Ford and Mercury vehicles of the 1978–2012 Panther platform.
Between 2004 and 2019, D3 vehicles have been assembled at Chicago Assembly in Chicago, Illinois along with the D4 Ford Explorer. The D4 Ford Flex and Lincoln MKT were assembled at Oakville Assembly in Oakville, Ontario, Canada.
Overview
To achieve a more cost-effective design, the D3 platform rendered certain elements in steel, as with for example the suspension arms in stamped steel vs. cast aluminum.
Ford adopted a common 112.9 wheelbase for its D3 variants, three inches longer than Volvo's platform. Notably, where the Volvo platform used inline five or six cylinder engines, Ford adopted its transverse Duratec V6 engines to the platform — including later Duratec engines compressing their design (e.g., embedding the water pump deeper in the engine) to accommodate the platform. As with the front-drive P2 platform, a Haldex all-wheel drive (shared with the S80/XC90) was optional.
As the first front-wheel drive full-size car platform used by Ford, the D3 platform is also the first full-size Ford car produced with fully independent suspension, with a multi-link rear axle, coilover shocks and MacPherson front struts. The D3 is fitted with four-wheel disc brakes.
