There are lots of cars that can't reach the required PR in a series even when fully upgraded. Just look at the RR3 Wiki:Upgrades Strategy For 100% Completion, cars only appear in this table for a series if they can reach the required PR of all races in that series, otherwise they just aren't listed. As SM Racer pointed out, these cars can still be used to rerun these events once you have a gold cup but they can't be used to complete the series. Many series only have one car that can complete the series, all the other cars can't reach the required PR even fully upgraded.
