After four straight years of Formula One dominance from Sebastian Vettel and Red Bull, fans are ready for a change. The hope is that new engine regulations for the 2014 season will provide it. While a shake-up at the top of the standings is not guaranteed, major changes to engine regulations in the past have usually benefitted one specific group of constructors: those who build their own engines (or who are the sole customer of an engine company). Red Bull does not. It is reliant on Renault, who will also be powering Toro Rosso and Caterham (Lotus is using Renault engines this year but have yet to announce a supplier for 2014).
