Engineer to Lewis Hamilton: "We need to introduce a little lift and coast."

Hamilton: "How much?"

Engineer: "50 metres will be enough."

Lift and coast. Welcome to F1 in 2015, ladies and gentlemen.

It's an unwanted double for McLaren, who now have both drivers out of the race - the only retirements of the grand prix so far.

Painfully slow and unreliable.

These are bleak times at Woking.

On McLaren's woeful 2015: "Get everyone together and get a hand grenade [for the car]. It's not working."

Engineer to Jenson Button: "Box this lap - we need to retire the car."

Vettel's climb through the field is continuing. He passed Maldonado for fifth a couple of laps ago.

That Ferrari is working well after yesterday's problems.

Kev Heritage: 'Lifting & coasting' - the state of F1 in 2015. What a joke!

William Ogle: For a driver of Alonso's quality to have only finished twice this year (and neither in the points) is quite frankly, ridiculous.

Megacles: Eugh, poor Alonso. What an embarrassment McLaren-Honda are and wasting great drivers.

Engineer to Valtteri Bottas: "Everything is looking good. At this pace, Raikkonen will catch us just after the race. You are bringing the fuel back to target, continue like this."

1 Hamilton, 2 Rosberg, 3 Bottas, 4 Raikkonen, 5 Vettel, 6 Maldonado, 7 Massa, 8 Hulkenberg, 9 Kvyat, 10 Perez

Jessica: The awkward moment when you hear Will Stevens' accent on the radio for the first time and think he's an engineer.

Ya Gunners Ya: Stevens sounds like an angry teenager on Gran Turismo after he's been shunted off by a kamikaze driver.

Stewart: Is Danny Dyer driving Will Stevens' Manor this weekend?

Engineer to Will Stevens: "Grosjean has received a penalty."

A five-second time penalty is swiftly slapped on Grosjean after that incident, which seems fair.

Will Stevens: "So stupid - he comes across me every time he overtakes. What does he want me to do - go off the track?"

Romain Grosjean's good race has just taken a nosedive with a moment's carelessness as he put a lap on the Manor of Will Stevens as they entered the final turn.

The pass was clean enough, but the Lotus man moved across too soon, damaging the Manor's nose and giving himself a puncture.

"He hit me, he hit me!" the Frenchman chunters on the team radio.

No, Romain, you hit him...

Engineer to Jenson Button: "Fernando has retired - there is no reason why that would affect us."

We have the first retirement of the race and it is the McLaren of Fernando Alonso that is back in the garage.

No power in the car, is the word from the pit lane.

Engineer to to Nico Rosberg: "You have done a really good job on the brakes there. We want you to continue on - it will give you the chance to attack later on."

Nico Hulkenberg: "I had no choice - we would have collided."

Sebastian Vettel: "Where is Hulkenberg? I didn't touch him."
