The Ford CD3 platform (for "C/D-class") is a Ford midsize car automobile platform. It was designed by Mazda. The platform is designed for either front, all-wheel drive or Ford's hybrid powertrain.^[1]

The platform is based on a unitized welded steel body (monocoque) with an independent short long arms (SLA) double wishbone front suspension with stabilizer bar and an independent multi-link twist blade rear suspension with stabilizer bar.^[2]

Ford Motor Company uses the CD3 platform design from the Mazda partnership as its first fully "digital" car, allowing the company to cut months of development time, saving money and bringing the vehicles to market more quickly.^[1] Engineers were able to virtually build an entire car prior to initiating construction,^[1] thereby improving vehicle fit and finish, tool clearances and production line ergonomics.^[1]
