The Ford RS200 is a mid-engined, Four-wheel drive Sports car produced by Ford from 1984 through 1986. The road-going RS200 was based on Ford's Group B Rally car and was designed to comply with FIA homologation regulations, which required 200 road legal versions be built. Despite some rumors to the contrary, the RS200 was not based on the Europe version of the Escort, as were both its predecessor and successor.
Following the introduction of the MKIII Escort in 1980, Ford Motorsport set about development of rear-wheel-drive, turbocharged variant of the vehicle that could be entered into competition in Group B rally racing, and dubbed the new vehicle the Escort RS 1700T. A problem-filled development led Ford to abandon the project in frustration in 1983, leaving them without a new vehicle to enter into Group B. Not wanting to abandon Group B or simply "write off" the cost of developing the failed 1700T, executives decided to make use of the lessons learned developing that vehicle in preparing a new, purpose-built rally car. In addition, Ford executives became adamant that the new vehicle feature all-wheel-drive, an addition they felt would be necessary to allow it the ability to compete properly with all-wheel-drive models from Peugeot and Audi.
The new vehicle was a unique design, featuring a plastic/Fiberglass composite body designed by Ghia, a mid-mounted engine and all-wheel drive. The cars were built on behalf of Ford by another company well known for its expertise in producing fibreglass bodies - Reliant. In order to aid weight distribution, designers mounted the transmission at the front of the car, but this 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 1 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. Such was the rush to complete the RS200, the Ford parts bin was extensively raided - the front windscreen and rear lights were identical to those of the early Sierra, for example, while the side windows were cut-down Sierra items.
Power came from a 1.8 litre, single turbocharged Ford/Cosworth" engine producing 250 horsepower (190 kW) in road going trim and between 350 and 450 horsepower (340 kW) in racing trim; upgrade kits were available for road-going versions to boost power output to over 300 horsepower (220 kW). Although the RS had the balance and poise necessary to be competitive, its power to weight ratio was poor by comparison and its engine produced notorious low-RPM lag, making it difficult to drive and ultimately less competitive. Factory driver Kalle Grundel's third place finish at the 1986 World Rally Championship Rally of Sweden represented the vehicle's best-ever finish in Group B rallying competition, although the model did see limited success outside of the ultra-competitive Group B class. However only one event later, at Rally Portugal, a Ford RS200 was involved in one of the most dramatic accidents in WRC history, claiming the lives of 3 spectators and injuring many others.
The accident at Rally Portugal set off a chain reaction and the RS200 became obsolete after only one full year of competition as the Fédération Internationale de l'Automobile, the governing board which at the time controlled WRC rally racing, abolished Group B after the 1986 season. For 1987, Ford had planned to introduce an "Evolution" variant of the RS200, featuring a development of the BDT engine (called BDT-E) displacing 2137 cc. Power figures for the engine vary quite a bit from source to source, but output claims range from as "little" as 550 horsepower (410 kW) to as high as 800 horsepower (600 kW); it's been said that the most powerful Evolution models can accelerate from 0 to 60 miles per hour (97 km/h) in just over 2 seconds, depending on gearing. Upgraded brakes and suspension components were part of the package as well. The ban on Group B racing effectively forced the E2 model into stillbirth; however, about one dozen of them were successfully run from early 1987 till late 1992 in Rallycross events all over Europe, and Norwegian Martin Schanche claimed the 1991 FIA European Championship for Rallycross Drivers with a Ford RS200 E2 that produced over 650 bhp (480 kW).
One RS200 found its way in circuit racing, originated as a roadcar, it was converted to IMSA GT Championship specification powered by a 750+ BHP 2.0 litre turbo BDTE Cosworth Evolution engine. Competing against the numerous factory backed teams such as Mazda, Mercury and Nissan, with their newly built spaceframe specials, despite being a privateer, the car never achieved any real success to be a serious contender  and was sold off later. The car is now used to compete in the Unlimited category at the Pikes Peak hillclimb.
FIA's homologation rules for Group B cars required the construction of at least 200 road-legal RS200s, and Ford complied, building these 200 vehicles with spare parts for another 20+ units put aside for the racing teams. Those chassis and spare parts were later also used to build a couple of non-genuine, so-called bitsa cars.
A total of 24 of the 200 original cars were reportedly later converted to the so-called "Evolution" models, mostly marked by their owners as "E" or "E2" types. Ford's first intention was to mark the FIA-required 20 "Evo" cars as series numbers 201 to 220 but as this was actually not necessary according to the FIA rules they later kept their original series numbers (eg. 201 = 012, 202 = 146, 203 = 174 etcetera).
The original bodywork tooling for the Ford RS200 was latterly bought by Banham Conversions, who used it to make a Kit car version based on the Austin Maestro. Due to being a basic rebody of the Maestro, the Austin-Rover engine ancillaries are actually to be found at the front of the vehicle.
