Valtteri Bottas upstaged his Mercedes world champion team-mate Lewis Hamilton on Sunday to win the season-opening Australian Formula One Grand Prix in a sizzling performance that he called his "best ever".
The flying Finn started second on the grid but got a jump on the polesitting Briton at the first corner and never looked back, scorching round the Albert Park circuit to take the chequered flag a massive 20.9 seconds ahead of Hamilton.
Red Bull's precocious Max Verstappen came third to join them on the podium after audaciously overtaking Ferrari's Sebastian Vettel midway through the race.
Here are five things we learned from Formula One's season opener:
Mercedes is the team to beat, again
Pre-season testing pointed to Ferrari having the upper hand but Mercedes proved consistently faster throughout the weekend as Lewis Hamilton dominated the free practice sessions and qualifying while his flying Finnish team-mate Valtteri Bottas got off to a stunning start by winning Sunday's race by almost 21 seconds from the Briton.
Ferrari blamed balance issues around the bumpy track and the team clearly has work to do before the next race in Bahrain, with Sebastian Vettel finishing a distant fourth, 57.1 seconds behind Bottas. His partner Charles Leclerc was fifth.
"This weekend is not the real potential of our car," insisted Ferrari chief Mattia Binotto.
Red Bull warm to Honda
Red Bull proved it has enough power in its new Honda engines to be a genuine contender this year, with the aggressive Max Verstappen charging to third and overtaking Vettel along the way.
"The car was working really well and we also look strong on the straights which is hopefully a good sign for the rest of the season," said the Dutchman.
His new team-mate Pierre Gasly suffered in qualifying from a team strategy error and didn't get further than the first session. The Frenchman started 17th on the grid but reaffirmed his potential by weaving through the field to finish 11th.
Ricciardo has horror show
Daniel Ricciardo's off-season move from Red Bull to Renault raised more than a few eyebrows and his 2019 campaign with his new team couldn't have got off to a worse start.
The Australian smashed his front wing just metres after the race start and was forced to retire on lap 31, ending a forgettable home Grand Prix.
His team-mate Nico Hulkenberg came home an encouraging seventh, showing that Renault might be able to compete with Haas and Red Bull this year.
"Nico showed in the race that the car belongs in the top eight and we'll be aiming for a smoother weekend in Bahrain and a strong result," said Ricciardo.
Norris takes rookie honours
Of the four drivers embarking on a first full season, British teenager Lando Norris was the standout.
The talented McLaren driver outshone his more experienced teammate Carlos Sainz by finishing qualifying a highly credible eighth and finishing 12th in the race.
"It's cool to finish my first race and get it out of the way," he said.
Of the other newcomers, Toro Rosso's Alexander Albon placed 14th, Antonio Giovinazzi was 15th in his Alfa Romeo and Williams' George Russell came home 16th.
Williams play catch-up, again
Williams appears to have made little progress from last year when it propped up the constructors' championship.
Robert Kubica, in his first race since a horror rallying accident in 2011, and rookie George Russell were bottom of the timesheets, by some distance, all weekend with the team admitting it was an achievement to simply get both cars to the finish line.
Russell said afterwards that Williams had found a "fundamental" fault with the car, which when resolved would see "a big leap". He didn't say what the fault was, or when it would be fixed.
