Force India drivers told to hustle rivals, not each other

Memories of last year's controversial collisions between the pair were revived in China when Perez went off off on the first lap after a brush with Nico Hulkenberg.

Ocon was delayed in the aftermath, although they didn't actually make contact.

"The first lap and especially the start is very, very difficult to manage," team COO Otmar Szafnauer told Sky F1.

"All sorts of variable are out of your control, including Hulkenberg or a Renault running you wide onto a surface that doesn't have the same grip, and then you come back in front of your teammate.

"It was a bit unfortunate for us that that happened, but it's very difficult for us to control a start or a first-lap incident.

"We just have to focus on telling the drivers that if it's a choice of running a competitor off or your teammate, you always take the competitor."

He added: "I've had some experience in competitive racing too, and it's really hard, because they are split second decisions that you make.

"If you know what's behind you and you've got a choice in that split second, choose a competitor and not your teammate is what we said, and they both understand that.

"I think in the future that will be going through their minds at the start, but it's really really difficult."

Force India has shown much improved performance in Baku, with both drivers in the top five in FP1.

Szafnauer said that the team now has the package it should have had in testing.

"First and foremost we had to get all the components on the car that we'd designed and developed in the wind tunnel, and once that happened then we had a good understanding of what the car was like.

"Like always you get real world feedback from the drivers and data you collect at the track, not just wind tunnel or CFD. You correlate to what you think you have and then start making changes, and that's a process we go through over and over to develop this car into the competitive car that it needs to be.

"It wasn't available in winter testing like it would have been for most teams, so we had to drip feed it in. I think the car we have here today is the car we should have had in winter testing, now we're learning and developing from here forward."
