In a shockingly quiet week for motor sport news, Tim Gray and Nick Daman dredge the bottom of the barrel for something to talk about. Fortunately Sam Smith is on hand to preview Formula E’s sextuple header in Berlin, two young US drivers talk about being stranded in the UK this season, and Declan Brennan looks back at the weekend’s Moto GP action. This week’s Big Interview is with Pipo Derani.

This week’s show includes an exclusive interview with Johnny Mowlem, who announces his retirement from professional motor racing after almost two decades. Graham Goodwin on brake problems in the World Endurance Championship, Nick Daman’s in Oslo with views on the futures of Felipe Massa and Jenson Button, and Tim Gray has the latest on F1’s sale to Liberty Media.
