McLaren's Oscar Piastri finished the first day of the new Formula 1 season in first place after Friday practice at the Australian Grand Prix.

The narrative of the weekend so far has been about Aston Martin's plight at the back of the field as much as the fight at the front, following the biggest regulation change in the sport's history.

Team principal Adrian Newey has laid bare the team's struggles across two compelling news conferences, and revealed as well that star driver Fernando Alonso is in a "hard mental place" as a result of engine partner Honda's lack of performance and reliability.

At the front of the field, Piastri was 0.214 seconds quicker than Mercedes' Kimi Antonelli at the end of the second session.

The Italian's team-mate George Russell was third fastest, ahead of Ferrari's Lewis Hamilton and Charles Leclerc and Red Bull's Max Verstappen.

World champion Lando Norris, seventh fastest in his McLaren ahead of the impressive 18-year-old British rookie Arvid Lindblad in the Racing Bull, was affected by a gearbox problem in the first session.

The competitive picture is still unclear after a day on which many of the teams and drivers admitted they were struggling to work out the optimum use of energy with this year's new engines. Management of the hybrid system is critical with the power split about 50-50 between internal combustion engine and electrical power.

Mercedes, though, set highly impressive times on their race-distance runs late in the session that seemed to underline their position as pre-season favourites.

Ferrari, also fancied by many coming into the season, spent much of the day at the top of the times, only to be usurped by McLaren and Mercedes.

Australian Piastri said: "If you can operate the car roughly how you expect it to, then you find a huge amount of lap time.

"I think we have been there or thereabouts. don't think we ever thought we were a long way behind Mercedes and Ferrari. I think we thought we were just a little step behind. And I am optimistic that if we get everything in a more optimal place, maybe we don't have the outright performance if everyone's at 100% but the biggest thing is how close you can get to 100% at the moment."

Antonelli added: "Massive learning every time we go on track and we understand more about the track. It looks like it is a close fight with the top teams. It is not going to be easy. Ferrari, McLaren, Red Bull, they all look strong."

Verstappen's pace was hidden by problems on his soft tyre runs and an off at the high-speed Turn 10 on his long run.

The focus has been on Aston Martin as a result of major problems with their Honda engine.

Alonso missed the entire first session because of vibration problems with his engine but was able to do 17 laps in the second, although he was 4.933 seconds off the pace in 20th place.

Aston Martin's biggest issue is the fact that vibrations from the engine are causing the batteries to break. Newey revealed the team are down to their last two batteries. "That, given our kind of rate of battery damage, is quite a scary place to be in," he said.

Alonso said: "Not much learning to be honest, unfortunately the Honda issue in P1 and some Honda issues in P2 as well a little bit limited our number of laps today. That was not needed again because we need to recover a little bit in terms of understanding the car and the window where this car operates.

"We brought a completely new (aerodynamic) package into this race and we need to understand where to run it. Hopefully more laps tomorrow.

"Obviously I feel disappointed to not have more batteries in stock, only supplying one team but it is more a question for them."

Completing the top 10 was the second Red Bull of Isack Hadjar and Haas' Esteban Ocon, whose British team-mate Oliver Bearman was 11th.

The headline lap times may well not be a true reflection of outright pace as the top teams all did their laps at different times of the session - Mercedes running relatively early and Piastri late, when the track would have been faster.
