Inside McLaren: Secrets and techniques of Fernando Alonso’s unbelievable Baku drive

Alonso’s entrance proper tyre might be seen beginning to collapse after a collision on the Azerbaijan Grand Prix

Fernando Alonso described his drive within the Azerbaijan Grand Prix, by which he took a badly broken McLaren to a seventh-place end, as “probably the greatest races of my life”.

Solely now, although, can or not it’s revealed precisely how good a efficiency it was.

The Spaniard slipped beneath the radar within the rapid aftermath of the race in Baku, most likely as a result of occasions on the entrance have been so dramatic.

However Alonso’s afternoon additionally deserves exploring.

BBC Sport was given unique entry to the two-time champion’s automotive on the McLaren manufacturing unit because it arrived again from Baku and might reveal the extent of the injury and the impact on its efficiency.

Alonso himself was proven images of the injury to his automotive on Monday, and stated on Twitter: “Now I’ve little doubt. It was an unrepeatable race.”

It isn’t the primary time the two-time world champion has talked up his personal performances since becoming a member of McLaren and being saddled with an uncompetitive automotive. With out judging the opposite events, although, this time it was undoubtedly justified.

Racing director Eric Boullier, who confirmed me across the automotive, stated the Spaniard’s efficiency was “a mega race. What he did is unbelievable.”

How unhealthy was the injury?

Alonso was caught in a collision with two different vehicles between turns two and three on the primary lap and suffered punctures in each his right-hand tyres. By the point he reached flip 15, two corners earlier than the lengthy pit straight, it was right down to its wheel rims.

The 36-year-old in some way dragged the automotive again to the pits, however within the course of it suffered in depth injury.

The aerodynamics of System 1 vehicles are extraordinarily delicate, and every flick and curve on the extensively sculpted bodywork is there for a purpose – to reinforce efficiency.

I used to be not allowed to take images, for confidentiality causes. However essentially the most dramatic injury to Alonso’s automotive was to what’s referred to as the ‘tea-tray’ – the a part of the ground that stands proud beneath the drivers legs, and which helps outline the airflow beneath and across the sides of the automotive.

Within the entrance of this there was a triangular gap, about 30cm by 20cm, in addition to important injury to the forefront, as if somebody had set about it with a strong hammer. A few of the heavy tungsten ballast that’s saved within the flooring was lacking.

Behind the automotive, there was injury alongside the right-hand aspect of the ground all the best way from the very again of the diffuser – the upward slope on the rear – to ahead of the rear wheel.

Two sculpted curves on the right-hand aspect of the rear diffuser have been gone. In entrance of the rear tyre, two key aerodynamic shapers have been lacking, too – what McLaren name a fence, a longitudinal curve, and a spat, a form of vertical, rectangular scoop-shape.

All in all, Boullier, stated the injury price “20 factors of downforce, roughly – so half a second a lap”.

Regardless of this, after altering tyres and entrance wing, Alonso returned to the race and lapped sooner than team-mate Stoffel Vandoorne on all however a handful of laps.

How did he get it again to the pits?

Even getting the automotive again to the pits within the first place was one thing of an achievement, Boullier stated.

“The entrance tyre deflated right away after flip three after which it takes a while earlier than you lose the tyre from the rim,” Boullier stated. “The rear proper tyre deflated I feel round flip 15.

“You possibly can see [from the television footage] that after coming into the pit lane, the automotive is just not driveable, and truly he hit the wall on the right-hand aspect.

“At that stage, he instructed us after, he didn’t know learn how to deliver the automotive to the pit. He did not know if the automotive would steer. He simply tried to go straight on the quick lane and he thought he would depart it there and we might take it out [of the race].

“On the final minute, he turned and the automotive steered into the pit-stop bay. We made a joke with him and stated it was the very best positioning of the weekend.

“He stated: ‘Let’s change the tyres and entrance wing and go.’ From the pit wall, I noticed these flames throughout the ground. The automotive was on hearth.”

McLaren couldn’t see all of the injury, as a result of the entrance flooring is hidden by the aerodynamic shapers behind the tyres.

So after checking the automotive was structurally sound and secure, they despatched Alonso again out with new tyres and entrance wing. He spent a few laps asking what they may see from the information and whether or not they wanted him to alter any settings. It turned out that, whereas it had misplaced downforce and was theoretically slower, it felt OK to drive.

“Truly, the automotive was nonetheless roughly balanced, surprisingly,” Boullier says. “The rationale was there was this huge gap within the entrance flooring, so we misplaced downforce on the entrance and rear. So the automotive was not very effectively balanced, however it was nonetheless driveable. He did not complain about something, not even driveability.”

How did Alonso’s efficiency evaluate with Vandoorne’s? The Belgian was “struggling together with his tyres greater than common,” Boullier says, however Alonso completed two locations forward, and his common lap time was 0.521 seconds faster, in a automotive theoretically 0.5 seconds slower.

How did Alonso do it?

This isn’t the primary time Alonso has over-achieved in a broken automotive.

In qualifying on the 2006 Italian Grand Prix, a rear tyre failure left his Renault with damaged rear bodywork, however he went on to set the fifth fastest time – and sooner than team-mate Giancarlo Fisichella in a wholesome automotive.

Renault’s sporting director Alan Permane, then a race engineer on the group, stated of that efficiency: “Half the automotive was ripped off. We measured the downforce he’d misplaced, calculated what that ought to have translated to in lap time, and he misplaced nowhere close to that. It is like he form of refuses to simply accept it.”

Now, Boullier says: “He has this facility to modify his driving fashion all the time to go well with the automotive steadiness. He is likely one of the very uncommon ones. Relying on the steadiness, whether or not you will have entrance [brake] locking, rear locking, right away he adjusts his driving to not harm the tyres. In that case, it helped him loads.

“I evaluate him generally to a shark when it smells blood within the sea. Then it begins to chase. Fernando is similar. In that mode, he determined: ‘Change the tyres, let’s return racing, simply examine the steadiness and inform me what I have to do if I want to alter one thing.’

“All weekend, truly, he was telling us: ‘Nothing is vital aside from ending the race. It’ll be chaos. We have to undergo the chaos and end the race and we might be within the factors.’

“I feel that is why he got here again saying: ‘Change the tyres, change the entrance wing, don’t be concerned, I’m going to drive it like it’s.'”

Boullier believes that Alonso’s mindset in these early races has been affected by the group’s tough begin to the season, with a automotive far off the tempo they have been anticipating.

After justifying their resolution final 12 months to separate with engine companion Honda on the premise that they’d probably the greatest chassis on the grid, McLaren have joined forces with Renault solely to seek out they’re round a second lap slower than Crimson Bull, who use the identical engine.

Alonso has certified 11th as soon as and 13th 3 times within the first 4 races. McLaren’s lack of tempo has led to chief technical officer Tim Goss being faraway from his submit.

But, within the races, Alonso has taken three sevenths and a fifth, and he’s sixth within the drivers’ championship. Largely because of him, McLaren are fourth within the constructors’ championship.

This, Boullier believes, has influenced the group as effectively. In any case, they may have determined to retire the automotive in Baku, given the extent of the injury.

“Possibly we received conditioned as effectively by him all weekend saying: ‘We have to end the race; that is the important thing,'” Boullier says. “We are also in a unique place. Qualifying tempo is just not our greatest and so now we have shifted our mindset to: ‘We have to seize any factors we are able to.’ And meaning by any means we have to end the race.

“That is our mindset since Australia. We wish to capitalise on the primary 4 races and seize as many factors as doable.”

Was it considered one of Alonso’s greatest races?

Drives like this go down in F1 folklore. Ayrton Senna profitable in Brazil in 1991 caught in sixth gear for the previous few laps. Michael Schumacher ending second in Spain in 1994 caught in fifth gear for a lot of the race. Or Alonso himself in Malaysia in 2010, scuffling with a malfunctioning gearbox whereas battling with Jenson Button’s McLaren.

Boullier has labored with Alonso at McLaren for greater than three years, and earlier than that they have been rivals when the Frenchman was at Lotus – now Renault – and the driving force at Ferrari. How does Boullier fee Alonso’s race in Baku?

“Whenever you see the situation of the automotive, positively it is likely one of the greatest ones,” he says. “He did another superb issues – some instances whenever you really feel he’s in one other world.

“The consistency he had with the tyres and tyre degradation and managing the tyres, particularly with the protection automotive and every little thing, and he did it.

“Then, on the last security automotive restart, we stated: ‘Oh my god, with the automotive he has, everybody goes to move him.’ However no.”

Actually, Alonso went on the assault, and took seventh place from Williams’ Lance Stroll on the final lap.

“He’s an actual fighter,” Boullier says.
