Focus ST, available in either three or five door hatchback variant, uses the Ford Duratec ST, a turbocharged 2.5 L 5-cylinder engine producing 225 PS. The Ford Focus Mk 2 ST is also known as the XR5 Turbo in the Australian and New Zealand market, but is sold as a five door hatchback only.

Ford facelifted Mk2 Ford Focus in 2008. Cosmetically, the facelift brought the Focus in line with the Kinetic Design language seen on the 2007 Ford Mondeo, and 2006 Ford S-MAX & Ford Galaxy, whilst keeping with the general shape of the pre-facelift model.
