Ford RS200

The Ford RS200 is a mid-engined, all-wheel-drive sports car that was produced by Ford Motorsport in Boreham, UK, from 1984 to 1986. The road-going RS200 was the basis for Ford's Group B rally car and was designed to comply with FIA homologation regulations, which required 200 parts kits to be produced and at least one road-legal car to be assembled. It was first displayed to the public at the Belfast Motor Show.

History
Following the introduction of the MKIII Escort in 1980, Ford Motorsport set about developing a 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 would feature all-wheel-drive, an addition they felt would be necessary to allow it 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 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.

Power came from a 1803 cc, single turbocharged Ford-Cosworth "BDT" engine producing 250 hp in road-going trim, and between 350 and 450 hp in racing trim; upgrade kits were available for road-going versions to boost power output to over 300 hp. 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 WRC 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 the Rally de Portugal, a Ford RS200 was involved in one of the most dramatic accidents in WRC history, claiming the lives of three spectators and injuring many others. Another Ford RS200 was crashed by Swiss Formula One driver Marc Surer against a tree during the 1986 Hessen-Rallye in Germany, killing his co-driver and friend Michel Wyder instantly.

The accident at Rally Portugal set off a chain reaction and the RS200 became obsolete after only one full year of competition as the FIA, 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 later as BDT-E, displacing 2137 cc, developed by Briton Brian Hart. Power figures for the engine vary quite a bit from source to source, depending on the mechanical setup e.g. boost levels, power output ranges from 550 hp to 815 hp; although most typical output was 580 hp at 8,000 rpm and 400 lbft at 5,500 rpm of torque. The ban on Group B racing effectively forced the E2 model into retirement; however, more than a dozen of them were successfully run from August 1986 until October 1992 in the FIA European Championships for Rallycross Drivers events all over Europe, and Norwegian Martin Schanche claimed the 1991 European rallycross title with a Ford RS200 E2 that produced over 650 bhp.



One RS200, which found its way into circuit racing, originated as a road car; it was converted to IMSA GTO specification powered by an over-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 kept by the original owner. A parts car was built in England and later used to compete in the unlimited category at the Pikes Peak International Hill Climb, where it was driven by Swede Stig Blomqvist in 2001, 2002 and 2004 and in 2009 by former British Rallycross champion Mark Rennison.

In June 2024, Ford & Boreham Motorworks teased a "Remaster" of the RS200, alongside with the Ford Escort MK1 continuation.

Production
FIA homologation rules for Group B required the construction of at least 200 road-legal vehicles, and Ford contracted Reliant Motors PLC to construct these 200 units at their Shenstone facility, 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.

Evolution (E/E2)
Group B required any modifications and upgrades had to be homologated by building a further batch of 20 road models to certify the revised specification. Even though Group B had been banned by the time the evolution model was ready, Ford produced the road cars regardless.

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 (e.g. 201 = 012, 202 = 146, 203 = 174 et cetera). Changes were mostly mechanical, with the engine being designated BDT-E. Additional cool ducts were fitted above the roof, either side of the main engine intake.

'S' Version
During the sales programme a Canadian entrepreneur, Murray H. de Weerdt, approached Ford with a proposal to purchase 20 cars and to commission them to have a better level of equipment in an attempt to produce a more marketable "ultimate RS200". He coined the term "The 'S' Version" although permission was never formerly granted by Ford to use this designation however he went on to produce sale literature. Changes included wider seats, Air Conditioning, improved cooling and increased power. A total of 20 were produced, 16 standard cars and 4 evolution spec, including 4 in red. The deal ultimately never came to fruition although Mr de Weerdt went on to own one of the cars himself, chassis number 110. The remaining 19 were sold by Ford to private buyers. The full chassis number list is still available where the "S" designation can be seen.
