From Ford Wiki

The Ford D2C platform (for "Vehicle size class 2-door Coupe" and also known as DC2 and S197) is Ford's latest Rear-wheel drive Automobile platform. Currently the only vehicle using this platform is the 2005-present Ford Mustang, and its Shelby derivative.

The platform basics are a MacPherson strut suspension in front and 3-link Solid axle in the rear with a Panhard rod. Unlike previous Special Vehicle Team (SVT) Mustang variations, the Shelby GT500 does not include a Independent suspension, but also has a solid rear axle.

Considered a new platform by Ford Motor Company D2C is loosely based on the Ford DEW platform which served as the basis for the Lincoln LS, Ford Thunderbird, and Jaguar S-Type. The 2005 S197 Mustang was originally designed to use a "Lite" version of the DEW98 platform, but while that plan was eventually scrapped as too expensive, most D2C platform development completed prior to that decision was retained. This led to the carryover of several DEW98 chassis components. These components include the floor pans, portions of the Transmission tunnel, the front frame rails, and basic Fuel tank design.

Differences between D2C and DEW98 are most noticeable in the Suspension (vehicle): The DEW98-based Lincoln LS uses a 4-wheel Independent suspension Double wishbone suspension. The D2C platform's MacPherson strut front suspension and Solid axle rear suspension are less expensive to produce than DEW's more complicated setup. D2C also shares components with other Ford platforms. These include Ford's global C1 platform, with which D2C shares front Strut and rear Trailing arm components.

Ford's The Way Forward plan called for Mustang derivative models (such as a 4-door) to be launched by 2008, but that never occurred. In January 2009, Ford announced they are not currently developing a replacement platform, meaning D2C will likely underpin Mustang for years to come.
