Many of the WRC cars are FWD in production, but the modified WRC version is AWD. For example, the Ford Focus, Peugeot 206, Hyundai Accent, and Citroen Xsara are all FWD. The WRC drivetrain is so heavily modified, it bears virtually no resemblence to the production version.
Only the Subaru and Mitsubishi are AWD in production. I don\'t know about the Skoda Octavia.
