I guess I don't tell something new when stating that RB engines have made an impact regarding performance, reliability, quality and unmatched runtimes as far as I can judge with the last point pointing at the C6 BB(BBT). But as a driver that also drives a lot for fun between the competitions and therefore wanting to use engines with cheaper spares (or also for drivers that drives just for fun) I can't really understand why there is still a S3 and nomore S7C and also no C6 CC as it could be the impression while another company comes up with exactly this segment of engines at the moment.
