McLaren's Oscar Piastri powered to the fastest time ahead of Mercedes' Kimi Antonelli in second practice for the season-opening Australian Grand Prix on Friday as drivers grappled with sweeping new engine changes.
The Australian sent 125 000 fans at his home track into a frenzy by blasting round Albert Park in one minute 19.729secs, 0.214 clear of Antonelli.
Antonelli's teammate, pre-season favourite George Russell, came third, a fraction clear of Ferrari's seven-time world champion Lewis Hamilton.
"A lot of learnings but overall a reasonably good day," said Piastri, who won seven times last year but could only finish the championship in third.
"FP2 ran smoothly and we were able to find a bit more consistency and the car behaved more as we expected, which was good."

After a dismal debut season with Ferrari last year, an upbeat Hamilton was encouraged by what had been achieved so far by the Scuderia.
"It was challenging at times on track, but we maximised our laps and executed to the best of our ability, getting some good information," he said.
"Lots of work to do but I'm looking forward to getting back in the car tomorrow."
Charles Leclerc, in the other Ferrari, was fifth with four-time world champion Max Verstappen sixth after spending half the session in the garage having stalled his Red Bull.

McLaren world champion Lando Norris clawed his way to seventh, more than one second off the pace, after managing only seven laps in first practice due to gearbox issues.
"We've got some good bits of data to go over from the second half of FP2 and there's plenty we can learn from what our competitors have been doing," said Norris, while admitting to "a tricky first day".
Racing Bulls' impressive rookie Arvid Lindblad banked an eye-opening eighth, a place ahead of Isack Hadjar – the man he replaced and who is now Verstappen's teammate.
F1 BEGINS NEW ERA
It was the first proper test of far-reaching new engine and chassis rules with the hybrid power units now 50 per cent traditional combustion and 50 per cent electric.
With a finite amount of energy available, drivers had to carefully manage their batteries on each lap, working out when to deploy while building it up back through braking.
The challenge of Albert Park is its long sweeping straights, which deplete batteries, and relatively few twisty turns to brake and charge it up again.
There have also been changes to the aerodynamics of the cars, which are lighter and smaller.
On a perfect Melbourne afternoon, Nico Hulkenberg led them out, but it was Hamilton who set the opening time.
Verstappen had an inauspicious start, stalling in the pit lane, while Russell clipped Lindblad on his way out and needed a new nose.
Verstappen's car was wheeled back into the garage, apparently stuck in gear, where he stayed for almost half an hour.
The drivers started on a mix of medium and hard tyres and Russell soon upstaged Hamilton as they jockeyed for places.
At the halfway mark it was Italy's Antonelli, Russell, Hamilton and Piastri.
Russell locked up and hit the gravel at Turn 3 as he pushed hard, as did Hamilton, but they both kept enough momentum to get back on track.
Piastri blasted to the top of the timesheets on soft tyres with 25 minutes left as Verstappen began climbing the leaderboard.
But the Dutchman was trying too hard and careered into the gravel at Turn 10 with debris flying off his car, ending his day early.
Fernando Alonso clocked 18 laps and Lance Stroll 13 as the troubled Aston Martins battle extreme vibration caused by the new Honda power unit.
Newcomers Cadillac – the 11th team on the grid – also struggled with Valtteri Bottas 19th and Sergio Perez last.
In first practice, Leclerc outpaced Hamilton with Verstappen and Hadjar third and fourth.
