F1 journalist Dan Knutson in Barcelona: "Red Bull is doing a very thorough race simulation. A crew member placed bottles of water at each of the seven seats on the pit wall where Christian Horner, Adrian Newey and the engineers sit (although they are not all out there now.)

"Daniil Kvyat did one lap and then came into the pits, stopped 50 yards away from the Red Bull garage, and shut the engine off. The mechanics then pushed the car to the garage, just as it would be pushed from the back of the grid to its starting slot on the grid.

"After a waiting period similar to what it would be on the grid before the start of the race, Kvyat then headed out with intermediate rain tyres fitted to the car, did one lap and pitted for a set of the soft compound Pirelli tyres. He is now off and running and doing the race sim."
