Mercedes' Lewis Hamilton reckons that the team's 2019 challenger, the W10, is "the best car" that they have ever made in Formula 1.
The comment comes in light of a record-breaking start for the team after five one-two finishes in the opening five races.
Hamilton and teammate Valtteri Bottas has finished in either first or second out of the first five races of 2019, with Hamilton taking three wins, and Bottas two so far.
Bottas took pole position in the recent Spanish Grand Prix, but a poor getaway handed Hamilton the advantage at lights out and what proved to be the race win.
“Ultimately, it's a fantastic car,” Hamilton said. “It's just the working window that I'm in, with my driving style, it's not always doing what I want it to do. But it's the best car we've made up until now.
“I've generally struggled with the car from Australia really. My qualifying in Australia [to take pole] was just okay – I was only a tenth ahead. But when I get things right, it should be different to that.”
Teammate Valtteri Bottas has also taken comfortably to Mercedes' 2019 challenger, after taking three pole positions and two wins as opposed to his 2018 campaign.
Last year saw him fail to win a single race over the course of the season, and now he trails Hamilton in the championship by just seven points going into round six at Monaco next weekend.
“Valtteri's settled nicely into the car, he's quite happy,” Hamilton added. “I don't know if it's driving style yet, I'm still looking into it, but there are definitely areas, and of course I will continue to focus on that at the factory, and this week, I'll be dialling in to try to really understand."
