Renault F1 drivers making 2018 car development 'much easier'

The drivers are in their first full season as F1 team-mates, with Hulkenberg arriving from Force India ahead of the 2017 season and Sainz joining from Toro Rosso midway through last year.

Hulkenberg has enjoyed a markedly stronger start to 2018, outqualifying Sainz three times and outscoring him 22-3 in the standings - but Bell says both drivers have been a huge asset to the development of the RS18.

"They are brilliant, those two," Bell said. "They are completely aligned about what they say about the car - and it's not because it's some sort of conspiracy!

"The car has got some obvious faults which they pick up on and tell us race after race, and they are completely aligned.

"A lot of those faults are common up and down the pitlane, nervous entries, mid-corner understeer and lack of traction on the exit.

"Some teams have got it more than others, the traits are quite similar, I suspect.

"The drivers are great, aligned on the issues of the car and that makes our jobs much easier. It's been a real pleasure to work with both of them."

When Bell's comments were put to Hulkenberg by Autosport, the German said: "Yeah, we seem to want the same thing from the car.

"That's good, both drivers asking for the same sort of thing, giving the same sort of feedback, makes it easier for the team to tackle the problems."

Asked what the process of working with Sainz was like, he said: "It's been OK. There's not any process, to be honest, because it works fine without anything.

"We're both doing our job, we're professional enough, we have respect for each other.

"We're both trying to do the best job for the team and for our own careers, it works totally fine."
