RBR have been very vocal in their criticism of Renault as everyone knows and probably with some justification, but I find it strange they keep on airing their dirty linen in public. I don't really know what Horner and RBR top brass quite hope to achieve. Now Renault's top man Cyril Abiteboul has accused Adrian Newey of lying. http://www.theguardian.com/sport/2015/mar/25/renault-accuse-red-bull-adrian-newey-lying-formula-one Even when RBR & Renault were winning Horner was always sticking the boot in, even with a 4 times championship winning engine. You can see why Renault are looking to get back to a full works team. To me although the engine is a problem the RBR 2015 car is also not there yet, I just find it strange after one race they are openly criticising each other. This weekend will be interesting especially if a poof of smoke appears out of one of the Red Bulls.
