Who’s fast and who’s not? A closer look at the lap times from Jerez testing
15 February 2010 by Keith Collantine


Lewis Hamilton was fastest in the final day's testing at Jerez

F1 Fanatic has obtained detailed breakdowns of the fastest lap stints and lap times down by each of the cars in the most recent test at Jerez.

What can they tell us about which teams are quick and who’s off the pace? Find out below.
The problem with testing

Using test times to work out which teams are competitive has always been tricky. It’s harder than ever this year for two reasons.

The race refuelling ban means teams are now testing their cars with anything between a few laps’ worth of fuel and 200kg for a full race distance.

The teams have also become more reluctant to issue lists of lap times. While it was often possible to obtain these in recent years, at Jerez they were not being distributed.

In order to obtain the data for this article, I made notes directly from the timing screens in the media suite. Of course, this is very restricting and time-consuming, so I decided just to follow the dry part of the final day’s testing in the hope it would provide the most recent and reliable information. Ideally, I would have also got the data from the warmer dry running on Thursday, but I wasn’t able to.
McLaren


Lewis Hamilton


Driver: Lewis Hamilton
Best time: 1′19.583 (lap 3 of a 5-lap stint)

The most interesting exercise of the final day at McLaren was Hamilton’s long run around midday, just as the track had finished drying out. It was interrupted by a red flag caused by Michael Schumacher, but Hamilton seemed to resume his stint where he left off once the track went green again.

He did 25 laps at first, beginning in the 1’24s and working his way down to the high 1’23s. After the interruption he did a further 11 laps, peaking at a 1′23.4. This was 3.1s off the fastest lap of the day at that point. However it was done on a fuel load good enough for at least half a race distance and on tyres that had covered over 30 laps in cold temperatures.

Although Hamilton was languishing at the bottom of the fastest lap charts at this time, his pace was good given his likely fuel load. Later in the day McLaren went to the opposite extreme, sending Hamilton out for a five-lap run when the track was most rubbered-in. Here’s what he did:

1′19.952
1′19.684
1′19.583
1′28.133
1′19.992

His 1′19.583 was the fastest time of the four-day test, nearly six-tenths quicker than anyone else on Saturday. Only McLaren know how much fuel was in the car, but it’s another persuasive sign the MP4-25 is on the pace.
Force India

Driver: Adrian Sutil
Best time: 1′20.180 (lap 2 of a 9-lap stint)

On Saturday evening Adrian Sutil insisted his best time was representative of Force India’s true performance. It was set during a nine-lap stint, which was typical of what other teams were doing. Here are his times from that stint:

1′20.253
1′20.180
1′20.573
1′22.007
1′21.543
1′22.035
1′22.492
1′23.169
1′23.875

The stint was towards the end of the day’s running (though not as late as Hamilton’s) when the track conditions were most favourable. He did one more stint after this and his times were:

1′24.970
1′23.663
1′23.749
1′24.014
1′24.362
1′23.808
1′24.980
1′25.196
1′25.422
1′26.045

Sutil was still running when the chequered flag came out and this looks like a heavy-fuel run which could have gone on longer. His last four laps show a clear lessening of pace, a reflection of the graining problems he talked about afterwards.

He may have ended the day with the second-fastest time but looking at what the other teams did I suspect Force India are actually in the middle of the pack.
Williams




Driver: Rubens Barrichello
Best time: 1′20.341 (lap 3 of a 10-lap stint)

Barrichello set his best time two hours before the end of the session, early in a fairly consistent ten-lap stint. It was the fastest time of the day at that point, improving on Schumacher’s mark by three-tenths of a second:

1′27.014
1′21.768
1′20.341
1′20.469
1′20.443
1′21.017
1′21.147
1′21.66
1′21.755
1′22.305

He only did one more stint after this run before being stopped by a gearbox problem, costing them valuable dry running. The team also had a hydraulic failure to fix earlier on in the test.

The shortage of data makes it difficult to make a call on where Williams are. But there’s nothing to suggest they’re very far off the pace and the early speed trap figures from the Cosworth CA2010 were encouraging.
Renault

Driver: Robert Kubica
Best time: 1′20.358 (lap 1 of a 5-lap stint)

Unusually, Renault spent most of the dry part of Saturday running doing short stints – nothing longer than six laps. Kubica set his best time in a stint which ended when the chequered flag came out:

1′20.358
1′20.544
1′28.227
1′21.05
1′27.319

His 1′20.385 was a 1.2s improvement on his previous best time. It looks as though Renault either unlocked some performance on the R30 late in the day or ended the test with a run on a decent set of tyres without too much fuel.

I suspect the times Kubica was doing before this late run, which were in the high 1’21s and low 1’22s, are a truer reflection of the R30’s pace.
Mercedes


Michael Schumacher


Driver: Michael Schumacher
Best time: 1′20.613 (lap 4 of a 10-lap stint)

Schumacher set his best time of the day earlier than anyone else – when the track was cooler and had less rubber on it – suggesting the car’s headline performance may be rather better than his fifth place on the times sheets at the end of the fourth day indicates.

I was watching at turns two and three during this stint and Schumacher was visibly pushing the car’s performance under braking, occasionally pushing it too far and gathering it up again by steering into the slide.

Shortly afterwards the Mercedes W01 rolled to a halt on the back straight. Unconfirmed reports suggested the team allowed the car to run out of fuel to work out how far they can push fuel mileage under race conditions. Whatever the problem was, it was remedied quickly enough to have him back on track again shortly after the session resumed.

On later stints he never got within 1.3s of his best time, suggesting he was working on heavier fuel loads. His times were consistent and all the signs are Mercedes have got a solid platform to build on and are among the front-runners.
Red Bull

Driver: Sebastian Vettel
Best time: 1′21.203 (lap 4 of a 10-lap stint)

The RB6 made its first appearance at the Jerez test and was in a less developed state than rival cars. The team were still having some reliability problems including a fuel pump problem which sidelined the car for three hours on Saturday.

Vettel must have had a reasonable fuel load in his car when he set his best time of 1′21.203 because it came during a ten-lap stint followed by a brief visit to the pits, during which time it appears no fuel was added, before returning to the track for another ten laps. Here’s his times from the first part of the stint:

1′21.427
1′21.423
1′31.349
1′21.203
1′21.656
1′21.980
1′22.230
1′22.174
1′22.193

Red Bull appeared quite a long way down the list of overall best times from the test but it’s early days for them and I believe they’ll be up there with McLaren, Ferrari and Mercedes in the later tests.
Ferrari



Felipe Massa


Driver: Felipe Massa
Best time: 1′21.486 (lap 2 of a 10-lap stint)

Massa’s car came to a stop twice during the final day test yet the driver completed more laps than anyone else – a mammoth 160 totalling 708 kilometres, more than two Grand Prix distances.

The team did not disclose why Massa’s car stopped the first time other than to state somewhat enigmatically on Twitter:

Maybe Felipe’s issue was the same experienced by many other drivers during these days of testing…

This could an an allusion to the widely-held belief that some teams were allowing their cars to run out of fuel on purpose. Massa’s car came to a halt at the hairpin leading onto the pits straight, allowing him to pull into the pit lane entrance where he was collected by his crew.

The huge amount of running clearly didn’t cause any problems for Massa, who did his best time of the day on his 151st lap:

1′21.509
1′21.485
1′21.851
1′22.73
1′22.991
1′22.883
1′23.258
1′23.531
1′23.954
1′25.859

This wasn’t all that much quicker than Massa has been lapping earlier on in the day, so I do expect these times were set with a fair amount of fuel on board. I certainly don’t think Ferrari are two seconds off McLaren’s pace as the fastest lap times of the day suggest.
BMW-Sauber

Driver: Pedro de la Rosa
Best time: 1′22.134 (lap 2 of a 7-lap stint)

Pedro de la Rosa did a lot of short runs in the afternoon as the team carried out aerodynamic tests. He set his best time in the longest of them, a seven-lap run. Here’s what he did:

1′22.273
1′22.134
1′22.29
1′22.796
1′22.847
1′23.135
1′23.211

On the face of it the team are probably in the lower half of the top ten on performance.
Virgin


Lucas di Grassi


Driver: Lucas di Grassi
Best time: 1′22.912 (lap 1 of a 5-lap stint)

After losing so much time with their wing failure on Thursday, Virgin were eager to get all the dry running they could on Saturday. The team stressed that they were concerned with ensuring the car worked as expected and suffered no further problems rather than looking for fast lap times.

Di Grassi’s quickest time was 3.4s off Hamilton’s best and was set during a short run around two hours before the end of the session:

1′22.912
1′23.608
1′23.902
1′23.224
1′23.611

It’s impossible to judge them against their target of being best of the new runners because the rest haven’t made it to testing yet. That will change next week when Lotus join the action at Jerez.
Toro Rosso

Driver: Jaime Alguersuari
Best time: 1′24.072 (lap 2 of a 7-lap stint)

Underlining the difficulty of interpreting test times, Alguersuari was fastest on Friday (with a 1′19.919) and slowest on Saturday. The STR5 was often near the top of the times sheets on the earlier days, but not on the last day as the team did aerodynamic comparison work. Alguersuari’s best was a full second off anyone else’s.

Notes on the data

A ’stint’ here refers to the number of flying laps done, for example a five-lap stint comprises an out-lap, five complete laps and an in-lap.

Over to you

What’s your analysis of the Jerez test? Whichteam do you think has the upper hand at the moment? Have your say in the comments.

salu2...

Un análisis detallado pero tan en el aire como el de cualquiera que se quiera echar a adivinar sin tener datos.
Claro que para "adivinar" que Sauber estará entre la 5ª y la 10ª escudería no hacía falta una gran bola de cristal...

Me quedo con la frase de Pedro: "Es un coche más rápido de lo que la gente se piensa"

con lo cauto que es pedro,que haya dicho eso me pone la vena optimista al rojo vivo. Yo les veo capaces de meterse en la lucha de los supuestos 4 grandes.seria grandioso!!!!!!

Hola Stuko,

Acabo de mirar el archivo, y esa foto del 20,6 la tomé exactamente a las 14:56. Y ese tiempo lo marcó justo al final del stint, es decir, que tras ver el panel con el 20,6 se metió para boxes (como muestra la flecha del panel).

Según la tabla que has colgado con los tiempos por vuelta, en ese momento Pedro estaría en boxes, pero no lo estaba

Esa fue de las últimas cinco foto que hice desde la posición de los foristas, y a las tres y poco ya me despedí y me fui unos minutos a final de recta donde tomé unas cuantas fotos hasta las 15:30.

Fallo del live timing de la web de Williams, de ahí cogían los tiempos supongo, que hubo ratos que no funcionaba. En un post que publiqué, gracias a otras fuentes, relleno algo ese hueco (aquí).


Antes que nada valoro que su autor viaje a los tests y se curre los artículos, además que mínimo que lo que escriba en su blog sea algo original suyo (las fotos de los tests de Jerez en su web lo son también). Chapó, de verdad, por él.

Aunque verdaderamente lo único que saco en claro es que al igual que Pedro otros pilotos también hacían su mejor vuelta al principio del stint que no al final, y además explica una causa (la que cito del post): "graining" en los neumáticos.

Es que sacar demasiadas conclusiones sin saber con certeza la carga de combustible me parece arriesgado. Por ejemplo el día anterior, antes que se pusiera a llover:

DE LA ROSA
10:44:31   7   1:21.101   
10:46:03   8   1:22.800   
10:48:06   9   1:20.736   
10:49:08   10  1:20.795   
10:50:55   11  1:26.836   
10:51:56   12  1:20.797 PIT

SUTIL
10:57:02   12   1:27.062   
10:58:03   13   1:21.428   
10:59:05   14   1:21.453   
11:01:16   15   1:23.156   
11:02:02   16   1:22.678   
11:03:03   17   1:23.292   
11:05:05   18   1:23.368   
11:06:06   19   1:23.248 PIT  

ALGUERSUARI
10:46:03   10   1:22.750   
10:46:35   11   1:22.750   
10:48:06   12   1:20.932   
10:50:09   13   1:20.288   
10:50:55   14   1:28.846   
10:52:57   15   1:20.329   
10:53:58   16   1:37.122   
10:56:01   17   1:21.000   
10:57:02   18   1:19.919 PIT 

MASSA
10:28:57   3   1:22.225   
10:29:58   4   1:21.872   
10:32:01   5   1:22.435   
10:33:02   6   1:21.603
10:35:05   7   1:21.923   
10:36:06   8   1:22.090   
10:36:52   9   1:22.896 PIT

¿Serían las conclusiones distintas?

Del Sábado eché de menos que PdlR no pudiera hacer al final un stint con menos carga.

A mí se me ocurre que le estuvieran mostrando el tiempo sólo de un sector del circuito (de ahí que no coincidan, yossi puso también una foto donde sale 20,1, con los tiempos por vuelta). Pero lo digo sin saber.

Yo creo que tampoco hay que darle mayor importancia. El coche parece que tiene posibilidades, pero hay que verlo en condiciones de competición con el resto. Ahora mismo es raro ver, incluso en escuderías como Virgin, un cierto optimismo. Y es muy probable que tengamos dos o tres chascos.

Yo veo fuerte a Sauber, pero me ha sorprendido también Toro Rosso (con los que sinceramente de partida no contaba demasiado), y quizás Force India.

Y KUBICA EL + AGRESIVO EN LAS ENTREVISTAS!!! ESTARIA ASESINANDO A BOB BELL CON LA MIRADA?

Y A SCHUMY LE VEO CARA DE ACABAR DETRAS DE PEDRO EN EL CAMPEONATO!!!

¡Qué chula la foto! Muchas gracias compañero!

chulas las tuyas compañero que eres un peazo de pofesional
Espero que te puedas volver a lucir esta semana y veamos algun rayito de sol que ilumine anuestro piloto....

Los demás nos iluminaremos con vuestras magnificas instantanesa. Mil gracias.

Saludos

Me temo que esta semana no cuento con la cámara de fotos buena para el circuito porque mi novia la necesitaba para el trabajo...

Pero está también Raul Leiva así que no creo que nos quedemos sin fotos!

A los que estáis por el sur, ¿cómo va el tiempo a estas horas por allí? Parece que lloverá casi todos los días.

Gonzalo eres un mamón! joder que envidia verte arriba de los boxes coñiiiiii.

Pues de tiempo andamos chungo... aqui se lleva de las 24 horas, 1 con sol el resto lloviendo a cantaros. Hoy parece que la cosa está mas paradilla, al menos en San Fernando, si ha llovido a sido insignificante, incluso llevaba el sol fuera un rato pero se volvió a nublar.

Y por supuesto que me llevaré la camara Bitter, si por si acaso salen los planes como pensamos! jejeje.

Saludossss

La cosa ahora está tranquila, porque la borrasca se está desplazando, pero en Sevilla este mediodía ha habido hasta pequeñas lluvias tropicales. Pero lo malo es que el jueves entra una señora borrasca por la Bahía de Cádiz. Es probable que se recojan entre 20 y 30 litros por metro cuadrado durante la jornada del jueves, mientras que mañana sólo se esperan entre 5 y 10 litros. Hablamos de volúmenes acumulados en todo el día desde las 8:00 hasta las 20:00.

Además, el río Guadalete se ha vuelto a desbordar hoy a su paso por Jerez de la Frontera, y se espera que lo vuelva a hacer el jueves. Para que os hagáis una idea, el Guadelete tiene ya un caudal con cotas de más de 6 metros, lo que supone el doble del caudal que tenía a principios de diciembre de 2009.

Y por si fuera poco, el jueves hay aviso amarillo por rachas de viento de hasta 70 km/h... No sé si alguien correrá con semejante pronóstico

Ya ha sacado la AEMET la última predicción oficial para mañana para la provincia de Cádiz. Nótese que las predicciones hechas por meteorólogos físicos sólo llegan a nivel de provincia, las que se muestran para las localidades son hechas por ordenador.



No parece muy mala...

Mañana a las 6:00 hora local estará disponible una nueva predicción en caso de que la que han hecho a las 19.00 de hoy no sea válida porque haya cambiado algo a mejor.

Pero si donde yo quería haber estado es abajo en la pista dentro del sauber, de paquete de Pedro ( ), cual lastre colocado en la parte baja rozando con la panza los pianos por donde pasa volando bajo el nº 27 pilotado por EL CRACK
