6. Ford RS200
When Ford decided to challenge Lancia and Audi in Group B, it created a purpose-built monster: the RS200. Its road-legal Stradale version, built from 1984 to 1986, inherited a tubular spaceframe chassis, mid-mounted 1.8 L Cosworth BDT engine making around 250 hp (later dialed up in Evoluzione spec), and all-wheel‐drive via a modified Escort drivetrain. With a curb weight near 2,200 lb and a short wheelbase, the RS200 Stradale launched to 60 mph in about 4.8 seconds.
Only 200 road cars were made to meet FIA requirements, each outfitted with functional aerodynamics (large rear wing, side skirts) and enough creature comforts for occasional street use. Though plagued by homologation delays and the tragic demise of Group B, the RS200 remains one of the most collectible—and frenetically engineered—road cars of its era.
