this is the real deal finally a solution to Torque steer. And a ford patent.
"The new Ford Focus RS is equipped with an innovative front suspension system known as a ‘RevoKnuckle’, which is designed to reduce unwanted steering disturbance and torque steer, the impact of torque on steering in front-wheel driven vehicles. Torque steer occurs during hard acceleration, cornering or driving on uneven surfaces, when torque on the driven wheels exceeds grips levels. It is characterised by sudden turning force on the steering wheel and can be exacerbated by vehicles with wide tyres and limited-slip differentials.
In Focus RS, the RevoKnuckle works in conjunction with a Quaife Automatic Torque Biasing limited-slip differential. Ford Team RS engineers have worked closely with Ford's Advanced Research Centre in Aachen, Germany to develop the RevoKnuckle technology specifically for the high performance Focus RS. It allows the simplicity of a traditional McPherson strut arrangement, but with geometry settings that minimize steering disturbances and torque steer, principally a reduction in steering offset."
