R.E.D. Ford Sierra XR4x4

[prpr]

That RED car was neither (it wasn't a homologated Sierra XR4x4).
The proper XR4x4 was GpA and GpN homologated.
The Sierra Cosworth was GpN, A and B (and the RS500 GpA for racing but not permitted in rallying).
The Sierra Saphire and Saphire 4x4 were GpN and A.

The RED Sierra was termed the '4T' or something similar.

The Sierra RS Cosworth was briefly homologated into Group B so as to allow the model to compete on international rallies, once 200 examples were produced. The Group A and N homologations followed once the production run reached 5000.

It is amazing that Ford did not develop a four wheel drive version of the Sierra RS Cosworth from the outset, it would have been ideally suited for rallying when Group A became the premier class in 1987.

The 2.9 XR4X4 was always going to be too heavy to be effective.
