Rally4 cars won’t certainly be so fast as they were last year and besides the restrictor the Fiesta will also carry more 50kg (1080kg is the new weight limit for every Rally4).

Btw, on Rally3 there will be no weight or restrictor size difference, despite allowing cars from 927cc up to 1620cc (1210kg and 30mm for all); with no 1.6L engines available on the 208 and Clio ranges, it remains to be seen if Peugeot and Renault will enter Rally3.
First of all we don't know if Rally5 will be close to Rally4. 4+ minutes difference in Canarias isn't exactly close and that was in largely wet conditions. It's likely that on dry the difference would be bigger.

Second thing is that while Rally4 would slightly slow down the difference will be probably very small in the end. Moreveor with the ongoing development it's likely that the Rally4 would again pull away due to the simple fact that they have more room for further development within the homologation.

Last but not least if I am not mistaken Peugeot and Renault both work on Rally3 cars.
