He struggled on Friday, but Sebastian Vettel found that little bit of magic once more on Saturday afternoon in Azerbaijan as he captured his third pole position in a row. However, Kimi Raikkonen blew Ferrari's hopes of a front-row lockout after making a crucial mistake in the last sector of his final run. Up until that point the Finn had looked set to steal pole position away from his team mate, but instead he’ll line up in P6 as Lewis Hamilton held onto second place for Mercedes.
QUALIFYING: Vettel makes it three poles in a row as he beats Hamilton in Baku
The Briton, lying second to Vettel in the world championship, finished 0.179s behind the German and a couple of tenths ahead of team mate Valtteri Bottas, though in truth neither Silver Arrow seemed truly in the hunt for pole.
The Red Bulls of Daniel Ricciardo and Max Verstappen were next up in fourth and fifth, the Australian pipping his team mate at the death after gratefully picking up a tow from a recovering Raikkonen.
Completing the top 10 in what was a thrilling session were the resurgent Force Indias of Esteban Ocon and Sergio Perez, making their first Q3 appearances of the year, and the Renaults of Nico Hulkenberg (who entered qualifying with a five-place grid drop hanging over him) and Carlos Sainz.
Q1 began with drama almost from the off. The session was barely four minutes old when Romain Grosjean become the first casualty. A huge lock-up at Turn 3 forced him to take the escape road, causing a big flat spot on his front-left tyre – and ultimately a gearbox issue ended his day before it had even properly begun.
As has been the pattern this season, Raikkonen started the qualifying process in impressive fashion and was the better of the two Ferraris at the beginning of Q1.
With all 10 constructors running on the quickest ultrasoft tyres early on, Force India continued to show signs of improvement with Ocon temporarily going P2 ahead of Mercedes and Red Bull.
But the big talking point of the opening session was a near calamitous moment for Toro Rosso pair of Pierre Gasly and Brendon Hartley. The duo were lucky not to become embroiled in a major accident when a slow-moving Hartley limped out of Turn 14 with a puncture and was almost collected by an onrushing Gasly.
That incident ultimately spelled the end for Toro Rosso, who were followed into Q1 elimination by McLaren's Stoffel Vandoorne, Sauber's Marcus Ericsson - the only driver to fail to reach Q2 this season - and Grosjean. On a positive note, rookies Charles Leclerc and Sergey Sirotkin moved into Q2 for the first time this year.
The second segment saw the top three teams – Ferrari, Mercedes and Red Bull – send all their drivers out on supersoft rubber with an eye on tomorrow's race, while the rest of the field emerged on ultrasofts.
And, similar to the opening session, it didn’t take long for the tricky corners to bring out the best and worst of the drivers.
Raikkonen suffered most after making a costly mistake and flat-spotting his tyres, forcing him to retreat to the pits for ultrasofts - a switch that will surely compromise him in the race when those in front of him will all start on more durable supersoft rubber.
The Finn did at least put the his purple-marked tyres to good use, ending the session just over a tenth quicker than Hamilton as Williams duo Lance Stroll and Sirotkin, along with McLaren's Fernando Alonso, Sauber's Leclerc and Haas's Kevin Magnussen (whose car lost bodywork at one stage) were the unfortunate drivers not to reach Q3.
The final session promised a great showdown, but who would come up with the goods? Ferrari laid down the gauntlet when Vettel produced a superb lap to move to the top, an impressive 0.342s ahead of Hamilton.
And with the German fluffing his final lap, Raikkonen making an error and both Mercedes and Red Bull lacking that extra bit of pace, that lap would ultimately prove enough for Vettel to secure his first hat-trick of pole positions since 2013. No wonder he'd later say 'the car was on fire!'
With the first four on the grid lining up in championship order and major gusts predicted to hit Baku on Sunday, the stage is set for what promises to be a thrilling Grand Prix.
