Stick or twist? This is the question Red Bull must answer as it considers whether to continue to use Renault or switch to Honda propulsion in 2019. When the deal was first done for Toro Rosso to become Honda's works Formula 1 partner last year, this seemed an optimistic hit and hope with a low probability of paying off, but Pierre Gasly's fourth place in the Bahrain Grand Prix proves it has become a more serious proposition.
Bahrain was just one performance and, even in the back of a car produced by one of F1's more modest teams, a gap of almost a second in qualifying to the Red Bull-Renault does not represent a miracle. But it suggests Honda is finally making real progress and the performance gap between it and Renault is narrowing.
Red Bull has attempted to do deals with both Mercedes and Ferrari in the past, but any such supply agreement is off the table. After all, why would either manufacturer want to power a team with the design capabilities to make it a threat against the works operations?
