Red Bull went into the 2017 Formula 1 season as favourite to take the fight to Mercedes, and the latest Autosport Podcast explains why it has failed to live up to expectations.
Autosport Editor-in-Chief Edd Straw is joined by Glenn Freeman and Scott Mitchell to discuss both the chassis and the Renault engine weaknesses that have left Red Bull a distant third so far this year.
There's also a look at the implications of Helmut Marko's recent comments on Red Bull's F1 future potentially depending on an independent engine appearing in 2021, and an explanation of how a throwaway comment from Max Verstappen in Bahrain was spun into an international incident.
Josef Newgarden's emergence as a true IndyCar star with his first Penske victory is also discussed, while Stephen Lickorish joins us for the latest on F4 driver Billy Monger after the 17-year-old's horrific accident at Donington Park.
We also look ahead to the Russian Grand Prix, and discuss whether it will be a Mercedes or a Ferrari weekend at Sochi.
