The 2009 Ford Focus RS was first seen as a concept in London earlier this year wearing an arresting green skin. Now the not-for-American-consumption production version shows off some blue metal in the gallery below.

Based on the Focus ST, the RS is made the red-headed step child of the range by adding an aggressive body kit, more power and better handling. Powered by a modified Duratec 2.5-liter 5-cylinder featuring 300PS and over 410Nm of torque, the 2010 Ford Focus RS should give a 0-60 time of 5.9 seconds and a top speed of 164 mph. Modifications to the standard motor include unique camshafts, a revised cylinder head and intake manifold.

Along with the boost in power, the 2010 Focus RS will ride on a 40mm wider track on 19-in wheels/tires with upgraded springs, dampers and anti-roll bars. A Quaife automatic torque biasing limited-slip differential will work with Ford's new ‘RevoKnuckle' suspension system which will act to prevent torque steer under hard acceleration.
