When Max Verstappen seized the lead of the Spanish Grand Prix from Lewis Hamilton, the Mercedes driver began a race-long pursuit of his rival.

Desperate not to lose his lead through the pit stops, Verstappen took the surprising step of pitting before his team told him to. That led to a sluggish pit stop, which Mercedes could have taken advantage of.

Instead they decided against bringing Hamilton in, and used a second pit stop later in the race to chase down the Red Bull on fresher tyres.

Both drivers felt the strain. Hamilton doubted he would be able to overcome Verstappen’s 22-second lead, while his rival grew frustrated at the need to push as hard as possible while preserving his fading tyres. Hamilton finally caught passed his rival for the lead with six laps to go.

Their team radio communications between the drivers and race engineers Peter Bonnington and Giampiero Lambiase reveal every punch and counter-punch of a fight for victory which was fought on the track and in the pits.

Laps 1-7: Verstappen seizes the lead

Start, Circuit de Catalunya, 2021
Verstappen’s superb start set up a fascinating battle between the title contenders

Verstappen made a fractionally better start from second place on the grid and dived past pole-winner Hamilton to lead the race. He reported some hesitation from his car early in the race, but that was the only time either driver reported any technical trouble during the grand prix.

Laps 8-12: Safety Car

Yuki Tsunoda’s AlphaTauri came to a stop at turn 10 with a loss of power. The Safety Car had to be deployed to recover his car.

Verstappen kept his lead from Hamilton, while Charles Leclerc and Valtteri Bottas behind them regained the nine seconds they had lost before it came out.

Laps 13-21: Verstappen feels the pressure

Max Verstappen, Red Bull, Circuit de Catalunya, 2021
The Safety Car erased the initial lead Verstappen and Hamilton built up

When the race restarted, Verstappen couldn’t draw away from Hamilton. The Mercedes driver sat within two seconds of him, threatening to jump into the pits as soon as the opportunity presented itself to get onto fresher tyres and ultimately take the lead of the race, as he had in Bahrain.

Laps 22-27: Verstappen’s surprise pit stop

Verstappen wasn’t told to pit before he came in for his first stop

Whatever Red Bull’s intention for Verstappen’s first pit stop was, he caught them off-guard when he appeared in the pits unannounced on lap 24. They sent him on his way with a fresh set of medium tyres, but lost around two seconds compared to a normal pit stop.

On the lap before he came in, Verstappen told his team to look at his tyre set and they discussed his “final front wing update”. Perhaps these were intended as coded triggers for a pit stop without alerting Hamilton behind.

“We’ll discuss after the race what went wrong,” Verstappen said after he returned to the track. Mercedes chose not to respond to Verstappen’s pit stop immediately.

Laps 28-29: Mercedes respond

By pitting four laps later than Verstappen, Hamilton passed up the chance to jump into the lead, ensuring instead he banked a tyre life advantage over his rival.

Laps 30-41: Hamilton closes in again

With fresher rubber and a quicker car, Hamilton cruised up to the back of Verstappen. While Mercedes had another set of medium tyres ready for Hamilton, Red Bull had only softs for Verstappen, so a second pit stop for them at this stage was out of the question.

Laps 42-44: Mercedes gamble on a second stop

Hamilton was poised to strike at Verstappen before Mercedes brought him in again

Hamilton appeared quick enough to pass Verstappen on the track. But Mercedes thought he would have a better chance later in the race when Verstappen’s tyres were even older.

As Hamilton arrived at the chicane on lap 42 he was told to pit – as late as Mercedes dared to leave it, to avoid tipping off Red Bull. Even so pitting at this stage was a risk. Had another Safety Car period occured, Verstappen would have had the chance of making a ‘free’ pit stop.

Strikingly, both strategists immediately recognised the similarity to a previous race. Hamilton used the same tactics to win the 2019 Hungarian Grand Prix, and they proved just as successful the second time.

44 Bonnington Lewis can we go menu position two just get out of the default. And go to strat mode seven when you can.

Laps 45: The chase

Bottas cost Hamilton almost a second and a half

Hamilton was concerned about the gap to Verstappen, but not the fact they had a car between them. Bottas could be expected to offer little resistance to his team mate. Though while he was reminded more than once not to hold his team mate up, Hamilton said nothing about the team’s other car as he bore down on it, even as he lost 1.4 seconds diving past on lap 52.

Verstappen never encountered his team mate on the track. But his frustration showed when his team advised him where he might find lap time compared to his team mate, aware that Hamilton was closing in.

Laps 58-60: Hamilton moves in for the kill

Verstappen was powerless to stop Hamilton taking the lead as lap 60 began

There was a brief period of radio silence at Mercedes as Hamilton closed in and performed a straightforward pass on Verstappen for the lead. It looked a foregone conclusion, and neither driver remarked on it.

Laps 61-64: Verstappen’s consolation point

Verstappen took another set of softs to grab the fastest lap bonus

Alert as ever to the strategic options on offer, Verstappen immediately spied the chance to grab the bonus point for fastest lap by making an extra pit stop to fit fresh tyres. He closed on Hamilton quickly enough that Mercedes decided they couldn’t risk doing the same with the race leader.

Laps 65-66: Hamilton brings it home

With little else to do in the closing laps, Hamilton’s thoughts turned to the start of the race, and what more he might have done to keep Verstappen behind.

After the chequered flag the Mercedes team congratulated themselves on a well-played tactical win. Red Bull team principal Christian Horner reflected that Mercedes were able to do what they did because of the gap behind the leaders. Had Sergio Perez been there, that might not have been the case.

But as Verstappen made clear in the press conference a few minutes later, the reason for Red Bull’s defeat was simple: They were “too slow”.
