Overheard in London: Autocar listens in to Formula E's UK return

Such instructions are the reality of pit-to-car communication: the outbursts picked up by TV commentary, such as Vergne’s post-race missive, are rare. Most of the communication is a short, professional transfer of information.

Once Vergne is on track, the team can’t control the car, so he has to pick the settings via controls on his steering wheel. There are two dials, each with 10 settings, six buttons (including a Mario Kartlike gold star to enable the Attack Mode boost) and six paddles for various regeneration options.

During his flying lap, Vergne is given both his split times and those of rivals – and they reveal that Jev doesn’t have the pace. As he tours back to the pits, his engineer offers some early feedback: “You lost a lot of time at the double hairpin.”

“The car just wouldn’t turn in there,” replies Jev, apparently genuinely bewildered. “I don’t understand. How can we go from an oversteering car yesterday to an understeering car today?”

The issues are different but the result is the same: Vergne qualifies 23rd, one spot behind Félix da Costa. Given that DS Techeetah have won back-to-back team titles and a record number of Formula E wins, the result is below expectations – but not entirely unexpected. “Formula E is so tight that if anything goes wrong you end up very far back,” says DS Performance director Thomas Chevaucher. “We will not score a lot of points today but will try to limit the damage.”

With just three hours between qualifying and the race and the cars under parc fermé restrictions for much of that time, there’s little room to improve the car. “We can do limited work to the mechanical set-up, but a lot of the improvement comes from software,” says Techeetah team boss Mark Preston. “Software is huge in Formula E.” That’s clear from the phalanx of computers located at the back of the garage, where the engineers, mechanics and drivers devote much of their focus. Even when the teams are allowed to work on the cars, it’s limited: only 17 mechanics, each denoted with a special armband, are allowed to touch the cars. Everything is overseen by an eagle-eyed scrutineer stationed at the back of the pits.

With Formula E’s short, bumpy street circuits, the set-up focus on a race weekend is as much about driver comfort as it is about chasing lap times. “Drivability is key,” adds Chevaucher. “It’s about giving confidence to the drivers. Formula E circuits are very bumpy and the grip is changing all the time.”

The activity builds to a flurry as the green flag appears and the cars head to the start. There’s a manic intensity as VIPs flood the grid, but once it clears, a quiet intensity settles in. The garage fills for the race: as well as the mechanics, scrutineer and your Autocar interloper, DS boss Béatrice Foucher and Stellantis motorsport chief Jean-Marc Finot squeeze in to watch the race. Even so, with the lack of engine noise, the pits are surreally quiet, despite 24 cars readying for battle metres away on the other side of the pit wall.

“Go Jev. Have a good race, mate.” As the lights go out, the distinctive, purposeful whirr of 24 Formula E motors pierces the silence - but the loudest noise is the crunching of carbonfibre as the cars bump and bang into each other and the track walls.

Félix da Costa and Verge emerge from the first-lap chaos in 18th and 20th, and both are soon instructed to use their Attack Mode boost. To do that, they have to drive through a special zone on the circuit, after which they’re rewarded with extra power for eight minutes.

“Make the most of it,” Jev is instructed. But any chance of progress is soon ended after contact between other cars leaves the track strewn with carbonfibre.

“Debris, risk of safety car.”

Sure enough, the electric Mini safety car is soon deployed, and Jev is told to maximise his efficiency. But Vergne also has instructions for the team: “Can you check the left-front? I hit something.” Vergne is instructed to pull across to the left when he next passes the pits so that a team member can sprint over to the wall and take a close look. It looks fine, so Vergne keeps going.

Shortly after the restart, the calm in the pits is disrupted by a huge bang from metres away. A car has struck the temporary pit wall right in front of the DS pit with enough force to shake it and make several people in the pit jump. Worse is to come when the TV camera reveals that it was Félix da Costa who made the impact, having been shoved into the wall by Porsche’s André Lotterer.

The DS pit erupts in indignation on seeing the move, but Vergne’s engineer remains an even-voiced oasis of calm: “Big risk of safety car with Félix da Costa in turn one.”

Vergne, though, had problems of his own. “What is [Edoardo] Mortara doing? He launched into me.” In the chaos, Jev has been hit as well, and for a second time he’s instructed to drive close to the wall for a damage assessment. He’s clearly still fuming. “He completely lunged into me.”

For Vergne’s mechanics, the recriminations can wait until later. “There’s still a lot of racing ahead, keep focused.”

At the same time, a disgruntled Félix da Costa arrives back in the DS pits, followed by a TV crew. The Portuguese driver heads to the back of the pits, where he sits down with his mechanics to watch a replay. Having shown admirable calm to that point, he lets rip with some suitable hand gestures to show his displeasure with the move, mostly for the benefit of the looming cameras.

On track, it’s increasingly clear that Vergne is unable to make much more progress. Still, with incidents everywhere there is hope. “With a possibility of penalties, we might still get 10th,” says his engineer.

Jev reports a bit of debris wedged in his car, which isn’t a surprise, given how much bodywork has been broken in the bruising race. More is to come when two cars crunch into each other at the double hairpin. “This is not racing any more,” says Vergne. “It’s madness.”

The late incidents lift Jev to an eventual finishing position of 12th – exactly where he finished Saturday’s race. “Sorry guys,” says Jev on the radio, shortly before breaking into his epic rant as he returns to the pits.
