This Ford Fiesta RS may not have the same prestige as the other Fiestas on this list  (particularly those used in Gymkhana), but keen minds will recall that this was M-Sport’s first global rally car. And interestingly enough, it was driven by Ken Block's wife, Lucy Block. Powered by a 1.0-liter three-cylinder engine, the peppy hatchback produces 177 horsepower and comes paired to a five-speed sequential gearbox. It may not be the most recognizable car on this list, but it definitely plays an important history in the Block racing lineage.
