George Russell offered a strong assessment of his first morning as a Williams driver having run at the Pirelli tyre test in Abu Dhabi.

The Formula 2 champion clocked 39 laps as he settled into his new environment for 2019 whilst also completing some evaluations between this year's compounds and those for next season.

“My feeling was very positive to be honest,” the Mercedes junior said. “After the first two runs, I had some issues with the balance and I wanted to change and play around with, but once we sorted that I was very confident in the car.

“I had a good feeling to keep on pushing forward and explore the limit, and I think as a driver, that’s really important to have that confidence in the car.

“Once we got the setup right, I had it.”

Russell's upbeat response comes despite driving what has been the worst car on the grid for much of the year in the Williams and though he has also driven the Force India and Mercedes, he refrained from making any comparisons.

“It’s difficult to judge because obviously every Formula 1 car is very different and I’ve only experienced 2018 tyres with a Mercedes and a Force India,” he claimed.

“I think Robert [Kubica] will have more feedback when he jumps in the car this afternoon.”

The Briton also revealed his first experience as a race driver rather than as a reserve also brought with it a lot more freedom with the team.

"I have more input to give what I would like for next season, whereas before with Mercedes or Force India, we were there to do exact test items and get the most out for the team,” Russell explained.

“This is a bit of both, and it’s really good for me to understand just little things like the seat, the steering wheel, just to see how I like it and anything I want to change.”
