The RS200 was designed from the ground-up as a purpose-built, mid-engined rally-supercar, and the 200 homologation road-legal models were essentially a by-product of Ford wanting to race the RS200 and show off their technology capabilities in the increasingly popular World Rally Championship. It was also designed by engineers who had extensive backgrounds in motorsports, and the engine had a smooth power delivery and functioned more like a racing car engine, as opposed to every one of the other highly modified production-based engines that Audi, Lancia and Peugeot had in their cars. The other famous Group B cars were all based on front-engined production models- and in both the Lancia Delta S4 and the Peugeot 205 T16's case - hatchbacks, and in the Audi Quattro's case - a luxury coupe. Although the Group B-spec S4 and T16 cars were mid-engined, they still originated as front-engined cars. Lancia's predecessor to the Delta S4 - the 037 - was also a mid-engined Group B supercar, but it was based on and had originated from Lancia's mid-engined Montecarlo production car.
