The team and driver errors that caused Hamilton’s retirement

2007 Chinese Grand PrixPosted on Author Keith Collantine

Lewis Hamilton, McLaren, Shanghai, 2007McLaren and Lewis Hamilton were left blaming themselves after a poor call on race strategy forced the championship leader out of a race for the first time this year.

While McLaren accepted their mistake in not bringing Hamilton in, the Briton apologised for losing control of his car on the way into the pits.

But when they analyse the mistakes that led up to his retirement from the Chinese Grand Prix they will recognise a series of missed opportunities to avoid the DNF.

Hamilton built up a lead very quickly in the opening stages with a series of quick laps:

Lap 2: Hamilton 1’47.6 – Raikkonen 1’48.5 (+0.9)
Lap 3: Hamilton 1’47.6 – Raikkonen 1’48.1 (+0.5)
Lap 4: Hamilton 1’46.3 – Raikkonen 1’47.1 (+0.8)

This continued up until the final laps before Hamilton’s first stop on lap 14 – Hamilton taking up to 1.2s per lap off Raikkonen (on lap six). But when Hamilton made his pit stop it was clear his front-left tyre was in very poor condition.

Raikkonen waited until his fuel load was lightest before he set his quickest laps – which were all fastest laps of the race up to that point:

Lap 15: Raikkonen 1’45.0
Lap 16: Raikkonen 1’44.3
Lap 17: Raikkonen 1’43.8

When Raikkonen pitted on lap 18 his tyres were in visibly better conditions than Hamilton’s had been – despite starting with more fuel, covering more laps and setting faster laps. Not only that, but he came out of the pits having cut Hamilton’s lead to 4.1s from 9.0.

It’s easy to be wise after the fact, but at this stage McLaren must surely have been alert to the fact that Hamilton was getting marginal on tyres. Nonetheless, Hamilton kept pushing:

Lap 20: Hamilton 1’43.8 – Raikkonen 1’44.3 (+0.5)

By this time several laps had passed since the last of the rain and some drivers further down the order had switched to dry weather tyres. Wurz set a new fastest lap on the 23rd tour on standard grooved tyres.

Up front the leaders were all on worn wet tyres and Hamilton’s plight was becoming clear – he was 1.6s slower than Raikkonen on lap 26 as the rain began again. Twenty seconds further back was Alonso, whose tyres were in even better condition having spent most of the race thus far stuck behind Felipe Massa.

Hamilton’s plight would have been familiar to Alonso – because exactly the same thing happened to him at Shanghai last year. Alonso wore his wet weather tyres out too quickly, had to pit for fresh rubber, and fell behind those who were able to continue on the same worn but hot tyres.

But as the track became slippery once more Hamilton’s situation was looking dire. Raikkonen caught Hamilton and, after a lap and a half of frantic defending by the Briton, passed him. Now Alonso was zeroing in on his team mate:

Lap 28 Hamilton 1’55.6 – Alonso 1’53.6 (-2.0)
Lap 29 Hamilton 1’55.3 – Alonso 1’51.6 (-3.7)

Lap 29 was the critical moment for Hamilton. He was unable to put Jarno Trulli’s Toyota a lap down, his right rear tyre was showing visible signs of damage, he’d been carrying a heavier fuel load for longer than anyone else, and his team mate was 3.7s faster than him. Yet McLaren kept him out:

Lap 30 Hamilton 1’56.8 – Alonso 1’49.1 (-7.7)

Finally the sight of Hamilton losing 7.7s in one lap pushed McLaren into action and the Briton was called in.

He got within one corner of dragging his car into the pit box where fresh dry weather tyres were waiting. But he took a fraction too much speed into the corner, the destroyed rear tyres refused to follow the front wheels around the bend, and the McLaren ground pathetically to a halt in a gravel trap scarcely much wider than the car.

Afterwards Hamilton avoided blaming the team for the bad call and apologised for losing control of the car on the way into the pits:

The tyres were finished, and these things happen. I’m sorry for the team, but I can still do it.

The team accepted responsibility for their mistake. Martin Whitmarsh said:

Quite simply we didn’t call him in. I think with hindsight we left him out a lap too long and I think his tyres were pretty worn.

The weather was pretty changeable at that time and we wanted to make sure that we weren’t taking any risks and that we had to cover Kimi. In the end it was decided we had to come in, but at that stage it was frankly a lap too late.

It was our decision. We were getting the weather information and it was coming and going. We didn’t want to come in and get on the wrong tyre. We took it one lap too long and we regret that now.

It’s the second time Hamilton has found himself on the wrong tyres this year – he switched onto dry weather tyres too early in the European Grand Prix. Was this a risk too far on a day when second or even third place could have made him world champion?

  1. Kirk, it gets more difficult now coming from 20th position and winning the race or getting on the podium. With the new 19,000rpm rev limits, its tough enough coming from 3rd to 2nd. Ask Massa the last race he had to start from the very back.

    Besides, if its possible to come from the back in say for example Monza, it would be totally reckless in thinking, to then expect the same to be done in Monaco, or Hungary.

    And as the cars get more and more refined, it would gever even harder still

  2. When Hamilton went into the pits it could be clearly seen that the right front tire was spent. Even though there was no tire change Hamilton should have been told the condition of his tires. He should have been able to feel his tires going away. He did not need to race with Kimi but true to his youth he chose too. A lack of communication along with over confidence cost him the race. All that being said I am still in amazment that a gravel pit in the entrance to pit road would be the spot where it went wrong.

  3. The problem with that tight turn is that, you just cant make it if ur tyres are canvas. Its ok if you have momentum, but a sharp turn like that and the tyre would never bite, so he didnt really go in too fast, the tyres just had no grip. A very good experiment that can be carried out is to see how such tyres would go from a standing start. My bet is that you will just end up with wheel spin and very little forward motion

  4. I understood what you meant Oliver. I am not saying that the turn was at fault I meant that I find it somewhat ironic the location of a gravel pit being placed at that particular location would end his race.

  5. Well at least Bernie can have the ultimate final he so longed for. And we may yet see the competitors take each other out like Bernie would wish.

    Strange still the smallest gravel trap.

  6. he could have gone in slower. But it was a hard situation… he didn’t have any grip and they entry was much wetter then the track.
    And as an f1 driver you try to look for the limit, even when entering the pits!
    Even at a slow speed, he would have gone off (i think), ok maybe he wouldn’t got stuck tough.
    I get that Mclaren wanted to wait for the rain, if it came…
    But it was so obvious he needed the tyres instantly…
    I believe Lewis with a bit more experience, in the future, will make the decision for himself to come in for new tyres!

  7. Spaniard here…

    I don’t see anything wrong with British TV commentators glossing over British drivers. It’s just natural and probably following the tastes of their target audience. Just watch the races while hearing the Spanish TV commentators and you’ll also feel a bias towards Alonso. I guess that TV sports events are too popular for getting the kind of balanced, unbiased and deeply technical comments that some of the posters would like to hear.

    However (and that’s the part pro-Alonso) I don’t see pro-LH people here recognizing some facts:

    1- Lewis is a rookie, he commits rookie mistakes, like not changing tyres before they wear out. It is not the first race where he has wear down a tyre. Before the China race he has been very lucky in those situations, however.
    2- Most critics to Alonso are targeting his lack of team play. I don’t know if anyone has analyzed why McLaren is this year’s number one builder. You must give credit to Alonso influence on the team and the car (please forget the espionage, I seriously doubt that with cars so different it really had any impact on such different designs) and must reckon that Lewis would not be heading for the championship with a car tuned by himself.
    3- Alonso joined McLaren assuming that, if there ever McLaren had to make a choice between the two drivers, he was going to be the preferred one. His main failure was to not have that written down in a contract. During the first half of the championship, when his results were not measuring up to the McLaren expectations, McLaren changed his policy so as to give their rookie driver the preferred treatment. When Alonso started to get better, McLaren changed their policy their “no preferred driver” attitude.

    Or at least that’s what I feel. Honestly, if Alonso is not the winner, I’d prefer to see Kimi taking the championship than having to bear with more media-induced LH hype.

  8. i think that it is definantly the teams fault for the hamilton retirment as much as i am a mclaren fan. They should of had him pitting much earlier than he was and has handing an easy world title victory for alonso and raikonen due to a lack of confidence for hamilton.
