Lewis Hamilton was pleased with the "small step forwards" taken by Mercedes after setting the second-fastest time in practice ahead of the British Grand Prix.
The Briton was 0.163 seconds slower than pace-setter Carlos Sainz in FP2, while compatriot Lando Norris was third and championship leader Max Verstappen in fourth.
Hamilton has yet to win a race this season, but he offered plenty of promise heading into a big weekend on home soil at a packed Silverstone with his performance in practice.
However, the seven-time world champion offered a word of caution over the ongoing porpoising issue that has dominated recent races.
"It's bouncing still, quite a bit," he said. "Not necessarily on the straights but through the corners it's pretty harsh – not physically harsh but in the car on the tyres and everything.
"So we still have work to do but it feels like a small step forwards.
"Our long run pace isn't as good as the other guys but it's not miles off. We've definitely made an improvement. I'm sure overnight we can work and improve the car a bit more."
Hamilton may have endured a difficult campaign to date, lagging as he does 98 points behind leader Verstappen, but he boasts an impressive record on his home turf.
The 37-year-old has won the British Grand Prix eight times and could become the driver to have won the most races at a single Grand Prix with victory this weekend.
Mercedes, meanwhile, have recorded eight of the last nine wins at Silverstone, while also taking eight of the last nine poles.
McLaren driver Norris looks good value to challenge for a second podium of 2022 after a surprising rise up the timesheets, having finished 15th last time out in Canada.
"As good as it looked, it is still difficult to put things together and be consistent but I am happy," he said.
"The car seems to be in a decent place, at least a little better than we were expecting."
Friday was rather unimpressive for Red Bull's Verstappen, who has won six of the nine races this year, including five of the last six.
But the Dutchman – who is out to surpass Valtteri Bottas and equal Rubens Barrichello as the driver with the eighth-most podiums ever (68) – is confident of finding improvement.
"It's always a bit tricky, of course, after not driving in FP1 and then FP2 becomes a bit of guessing, let's say it like that," Verstappen said.
"It was maybe not ideal, but also not a big issue. I think we know what we have to work on and that's what we'll try to do overnight.
"But, again, tomorrow probably it's raining so you have again different kinds of conditions. This time probably was not amazing, but it was also not really bad."
