Yes & no. Grp A cars were production based cars with a minimum build requirement. Essentially there was a requirement for a road going version of the rally car.
With WRC cars there needed only to be a production car providing the body shell. There was no requirement for this car to be 4WD or have the same engine size ... or in fact any of the componentry.
Whilst the initial thoughts were that removing the need for the production car would lessen costs and entice more manufacturers, the freedom to push boundaries with technological advancements added to the costs and limited the numbers who would compete.
