Lewis Hamilton remains confident Mercedes will be in good shape at the Russian Grand Prix this weekend, despite limited dry running during Friday practice.
Mercedes entered the weekend with lingering concerns over how the car will perform on the soft and super-soft after struggling on the same compounds in Singapore. During Friday practice in Sochi a diesel spillage on the track ahead of FP1 and rain in FP2 meant there was no meaningful dry running, but despite going into qualifying day with very limited knowledge of how the tyres will behave, Hamilton is not worried.
"I didn't go out on the slicks, but I don't have any concerns," he said. "Everyone is in the same boat, so I hope that tomorrow we get more dry running.
"Yesterday, the team did all of the analysis they could so, so we feel pretty confident about the weekend, but we will find out tomorrow."
Hamilton said the only thing to come out of Friday practice was trialling Mercedes' new front wing.
"I have to say today we learnt more than we did last time [in Japan] because we went out and tested the wing and got some information on a single lap. So we did get some information, but in terms of myself there is not much to learn from today."
