The new vehicle was a unique design, featuring a plastic-fiberglass composite body designed by Ghia, a mid-mounted engine and four-wheel drive. The cars were built on behalf of Ford by another company well known for its expertise in producing fibreglass bodies - Reliant. To aid weight distribution, designers mounted the transmission at the front of the car, which required that power from the mid-mounted engine go first up to the front wheels and then be run back again to the rear, creating a complex drive train setup. The chassis was designed by former Formula One designer Tony Southgate, and Ford's John Wheeler, a former F1 engineer, aided in early development. A double wishbone suspension setup with twin dampers on all four wheels aided handling and helped give the car what was often regarded as being the best balanced platform of any of the RS200's contemporary competitors. The Ford parts-bin was raided to help give the RS200 a Ford corporate look, for example the front windscreen and rear lights were identical to those of the early Sierra and the doors were cut-down Sierra items. Small parts-bin items like switchgear were also used to save development time and expenses.
