This weekend's Saudi Arabian Grand Prix is the final leg of the first "triple header" of the season.
From Suzuka in Japan, to the desert of Bahrain, Formula One now pitches up on the shores of the Red Sea in Jeddah.
AFP Sport looks at five talking points ahead of the fifth round of the 24-race season:
Advantage McLaren
Oscar Piastri put in a faultless display from pole last Sunday in Sakhir to make it three wins out of four for the British marque.
That moved the cool as ice Australian to within three points of championship leader and teammate Lando Norris, who took third in Bahrain.
With Max Verstappen, only sixth, and Red Bull struggling to keep tabs on the world constructors' champions, the 2025 title could well develop into a battle between the two McLaren men.
The team has always been insistent on "papaya rules", theoretically meaning no favoritism between the pair, but that even-handed policy will be put under intense pressure if the season develops into a battle between the two gifted drivers.
Looking ahead to Sunday's race Norris commented: "It's a really fast track and we have a quick car, so we'll be aiming to finish this triple-header strongly."
Red Bull to bounce back?
Red Bull's problems in Bahrain were well documented, and they will be desperate to bounce back on one of their favorite hunting grounds, with Max Verstappen winning in Jeddah in 2022 and 2024.
"Bahrain was quite a difficult weekend for us and didn't really go our way at all. We had some issues that set us back and we still have a lot of work to do on the car to get us where we need to be," said the four-time champion.
He slipped to third in the standings, eight points behind Norris, after trailing in over half a minute behind Piastri in Sakhir.
"We have a final push with this being the third race and final weekend of the triple header so hopefully we can find more pace and bring out a performance similar to Japan (his only win of the season)," he added.
The circuit
Sunday's race presents a radically different test for car and driver than last week in Bahrain. The fastest street circuit on the calendar offers multiple chances for overtaking, in stark contrast to the most famous street circuit of them all, Monaco.
With a record 27 corners and three DRS (drag reduction system) zones it can be counted on to serve up plenty of drama, with the walled sides leaving little room for error.
All the ingredients then for a thrilling race under floodlights on Jeddah's Corniche.
Golf in the Gulf for Gasly
Alpine finally got off the ground in Bahrain, with Pierre Gasly picking up their first points of the season in seventh.
"It's great to leave Bahrain with points on the board after three challenging races at the start of the season," reflected the French driver.
He celebrated his bold show by following Rory McIlroy's emotional Masters triumph at Augusta.
"I really enjoyed staying up late to watch the end of the Masters and I'm delighted for Rory McIlroy, one of our investors, to finally secure the green jacket. Congratulations to him!"
Toto praise for Russell
George Russell will be hoping to concentrate on the job he's paid to do -- driving -- rather than as a part-time electrician. The Briton, enjoying his best ever start to a season, took second last Sunday despite a myriad of issues he had to contend with in the cockpit in the closing stages.
"It was a superb drive from him under extreme pressure," marveled Mercedes team principal Toto Wolff.
Russell's teammate Kimi Antonelli did not enjoy the rub of the green and finished out of the points for the first time in his debut season.
"It has been easy to forget that Kimi is in the very earliest stages of his F1 career given his performances so far. Bahrain will prove an important milestone in his continued development," Wolff remarked.
