F1 rookie Daniil Kvyat not yet '100 per cent' comfortable

The Russian became the youngest starter and youngest driver to score a point on his F1 debut in Australia, while Red Bull boss Christian Horner recently described the GP3 graduate's season so far as "sensational".

Kvyat, 20, has out-qualified his more experienced Toro Rosso team-mate Jean-Eric Vergne five times in 11 races, and says he expects to become even stronger over the last part of 2014.

"I'm not at 100 per cent confidence level yet, but I expect a few things will come later on, maybe the second half of this year," Kvyat told AUTOSPORT.

"I still feel like my moment hasn't come in the car.

"I used to have a better feel for the car in previous stages of my career.

"I can drive it close to the limit, but unlike GP3 last year the car is still missing something to suit my driving style, and there is something still missing from myself.

"After the summer break I expect things to start going my way a little bit more, at least I hope so."

Kvyat says he is still learning how to set up his car properly across a weekend in F1, in order to consistently get the best out of himself and the machinery.

"The click hasn't come yet," he added.

"The car let's me do a good job at a certain level, but not yet the maximum level, and not yet in the right flow.

"I think we are coming close to achieving something that I really like.

"Everyone is trying to achieve the perfect car and I hope one day that I can do it. Then it will be to my liking."
