Apparently Red Bull are reall Plssed off with Renault, at present their power plants are 100hp down on the Mercs, which is near double what the diff was last season. I know that they are having mapping issues, but I find it hard to believe that the difference is purely in the mapping. As for reliability, that is really bad news. Riciardo down an engine in the first 5 laps of FP1, only 3 left for the remaining 19 races, I don't think so
they are in more crud than the first settlers at present, only marginally better than McLaren.
Update: Just read that the possibility even exists that Red Bull could pull out of F1 altogether if something is not done about the Engine Regs. Article here for information:
