Are you sure that it requires full upgrading? The max PR is 58.5 and it looks like the last Engine upgrade adds .5; however, I have not gotten close to that to see if everything but the last engine only gets you to 57.9.

Either way, the amount of gold needed to finish these 4 new series is rediculous. 637 is just slightly better than 812. Maybe they will back off of this the way they did for the F1 series when it originally required fully upgrading one of the Ferraris.
