摘要

Torque steer ought to be a problem in a 440Nm front-wheel drive car, but a total rethink of the front suspension allows the Focus RS to compete in the wet with the Impreza and Evo.rnWhen Ford built the first prototypes for the current Focus RS in 2005, the vehicles had four-wheel drive, unlike their predecessor. It seemed only logical for the next-generation when the car was to have a 2.5-litre engine producing 224kW (305hp) and 440Nm of torque from 2,300 to 4,500rpm.rnBut, when higher-volume products claimed priority over Ford's engineering resources, the RS was put to one side. When the project was resurrected a couple of years later, there were questions whether four-wheel drive still made sense.
