F1: Red Bull Denies Rumours of Renault And Vettel Split

Inevitably, as the scale of Red Bull's early season crisis becomes ever clearer, rumours of possible splits are now beginning to emerge.

Many of the reigning world champions' problems are undoubtedly down to engine supplier Renault and the French marque's struggle with the new V6 'power unit' rules.

So it is no surprise Red Bull, having won every title on offer since 2010 and every grand prix on the trot since last July, is supposedly on the move.
