I still chuckle when I hear about the "dominance" of Renault engine in the 2010-2013 seasons. Vettel won four titles in that time, yet back then I actually never heard of anyone talking of the dominance of the Renault engine. The only non-Red Bull team that did sorta well with a Renault engine was Lotus in 2012-2013. The 2012 Williams seemed like a nice car too, but its chances were ruined by mediocre drivers. Most of what Red Bull achieved was thanks to their aero dynamics brilliance. Renault may have delivered them some clever engine mapping or telemetry, but all that would have been useless without the RBR chassis.
