Daniil Kvyat learned the hard way how unforgiving F1 can be last week. The Russian racer finished on the podium at the third race of the season, but on home ground a catastrophic first lap ended up costing him his plum Red Bull seat.
Kvyat has been demoted to Red Bull's junior team Toro Rosso. In his place comes Max Verstappen, who stunned the F1 world by making his grand prix debut as a 17-year-old at the beginning of last season.
Now Verstappen is racing for the four-times world champions and is ranked fifth among the favourites to win this weekend's Spanish Grand Prix. His odds may be a lengthy 41.00, but expect him to become a more serious prospect for victory later in the year. Here's why.
Verstappen is the real deal
He may have come with a lot of hype but so far he's justified all of it. Had it not been for a power unit fault in the last race he'd have started and finished every grand prix so far inside the top ten.
Red Bull have a power boost coming
The Renault power unit is the weakest element of Red Bull's package. However an upgrade at the Canadian Grand Prix is expected to add in the region of 25bhp, trimming their deficit to the front-runners.
Some upcoming tracks will suit them perfectly
After Spain comes Monaco, where engine power matters little compared to a car's chassis and aerodynamics: which are traditional Red Bull strengths. Verstappen showed last year he is not a bit overawed by the demands of this unique circuit: in his first ever session at the track last year he was second-quickest. Later in the year the Hungaroring and Singapore are two further venues where Red Bull can expect to perform well.
His teammate will push him hard
In Daniel Ricciardo, Red Bull already have a three-times grand prix winner who saw off no less a driver than Sebastian Vettel just two seasons ago. He made short work of Kvyat - thrashing him 4-0 in qualifying so far this year. Ricciardo will be a serious opponent for Verstappen and the pair can be expected to wring the most out of the RB12.
Red Bull are peerless on the pit wall
Few teams have been as dependably razor-sharp when it comes to tactics as Red Bull. Their car's strength on softer tyres allows them more strategic flexibility which they are quick to exploit. The well-drilled pit crew may not be the fastest outright any more (that prize goes to Williams) but they give away very little and seldom make mistakes.
Verstappen's Red Bull predecessor Vettel holds the record for being the youngest driver ever to win a grand prix, at 21 years and 79 days. Will Verstappen, who turns 19 in September, break that record? Don't bet against it happening - it could even come this year.
