There was a glimmer of hope that Mercedes were moving in the right direction at Miami after Russell set the fastest lap in FP2 on Friday. But it’s clear that there is a fine window for fine-tuning the W13 after little changes were made on Saturday with Russell then unable to replicate his previous performance.
Porpoising was more prevalent once again and Hamilton feels there has been no real progress made since the start of the season.
“We’re the same speed as we were in the first race. So we’ve just got to keep trying,” he said. “We haven’t improved, unfortunately, in these five races.
“I’m hopeful that at some stage we will. But we’ve just got to keep trying, keep working hard.”
