Seems there is a big difference between Ford and Renault in the number of Rally5 cars vs Rally4 cars produced.

Ford has aprox 10 rally5 of ca 150 produced cars.
Renault aprox 140 Rally5 of ca 160 produced cars, mainly due to many cups.

Is the Clio that much better, so that the fiesta is outpaced

Was the Fiesta upgraded when it was renamed from R1 to Rally5 or is it still 150 hp?
