Measuring the 2013 team-mates

With just a third of the season remaining, we examine how the drivers have fared in their intra-team battles.

Ferrari

Fernando Alonso - Average Qualifying: 6; Average Finish: 3.
Felipe Massa - Average Qualifying: 7; Average Finish: 7.
Looking at the average grid slot for both drivers, it suggests that is where the Ferrari currently is on outright pace. There has been little to choose between the pair recently on a Saturday and Massa has even come out on top in the last two qualifying sessions at Monza and in Singapore, taking his Saturday win tally to five versus Alonso's seven. However, it is on a Sunday where the Spaniard shows his class, making up three places on average, and he is yet to be beaten in a race by Massa when both have finished in 2013.

McLaren

Jenson Button - Average Qualifying: 10; Average Finish: 8.
Sergio Perez - Average Qualifying: 11; Average Finish: 10.
Button's experience continues to show at McLaren, extracting more from the difficult MP4-28 than his young Mexican team-mate. Perez, though, has shown signs of improvement as the season has progressed, out-qualifying the 2009 World Champion on five occasions.

Lotus

Kimi Raikkonen - Average Qualifying: 7; Average Finish: 5.
Romain Grosjean - Average Qualifying: 9; Average Finish: 7.
Whilst still behind in both columns, Grosjean's form has shown marked improvement in recent races, out-qualifying Raikkonen at three of the last four events. Both drivers make up two places on their average grid slot during the race, suggesting that if Grosjean could qualify more consistently, he would be able to take the battle to the 2007 World Champion. As it stands, though, he has only beaten his team-mate on two occasions when both have finished.

Mercedes

Nico Rosberg - Average Qualifying: 4; Average Finish: 5.
Lewis Hamilton - Average Qualifying: 3; Average Finish: 5.
Four successive poles saw Hamilton edge ahead of his team-mate on Saturday pace, but Rosberg was back on top in Italy and Singapore - indeed Hamilton's grid penalty in Bahrain aside, the six-place gap between the pair at Monza was the biggest of the season. Whilst both have the same average finishing position on a Sunday, Nico Rosberg has retired on three occasions, whereas the British driver has completed every race this year.

Sauber

Nico Hulkenberg - Average Qualifying: 11; Average Finish: 10.
Esteban Gutierrez - Average Qualifying: 17; Average Finish: 13.
The gap between the Sauber team-mates is one of the widest on the grid with Gutierrez enduring a difficult maiden F1 season alongside the highly-rated Hulkenberg. The German has out-qualified the Mexican at every race bar Singapore this year with on average six places between the drivers. The fact that things are closer on a Sunday arguably owes more to other cars dropping out and Hulkenberg already running at the limit of the car's potential than Gutierrez possessing better race pace.

Force India

Paul Di Resta - Average Qualifying: 13; Average Finish: 8.
Adrian Sutil - Average Qualifying: 11; Average Finish: 10.
Adrian Sutil has cemented his place as the fastest man over one lap at Force India as Di Resta's qualifying woes continue. The Italian GP was the first time the Scot started ahead of his team-mate since the Spanish GP in May. Four DNFs in succession allow Di Resta to stay ahead on Sunday results, but his average would be worse had he finished in the position he was running upon retirement.

Williams

Pastor Maldonado - Average Qualifying: 16; Average Finish: 13.
Valtteri Bottas - Average Qualifying: 15; Average Finish: 14.
Valtteri Bottas started the season in encouraging fashion, outperforming the much more experienced Pastor Maldonado in both qualifying and the races. However, the Venezuelan has found pace as the season has progressed, narrowing the qualifying gap and actually edging ahead when it counts on a Sunday afternoon, even picking up the team's first point of the season in Hungary.

Toro Rosso

Jean-Eric Vergne - Average Qualifying: 13; Average Finish: 11.
Daniel Ricciardo - Average Qualifying: 10; Average Finish: 11.
There is no doubt that Daniel Ricciardo holds the upper hand when it comes to qualifying at Toro Rosso with Jean-Eric Vergne relying on the inclement conditions in Australia, Monaco, Canada and Belgium to get ahead of his team-mate. On a Sunday, though, the Frenchman makes up for his lack of qualifying pace, working his way through the field and even taking the team's best result since 2008 with sixth in Canada.

Caterham

Charles Pic - Average Qualifying: 20; Average Finish: 16
Giedo van der Garde - Average Qualifying: 20; Average Finish: 17.
Charles Pic's additional experience showed in the early part of the season, but since then Giedo van der Garde has not let himself down and equalled Pic's 14th place finish in Malaysia at the Hungarian GP. However, the team now find themselves in a no-man's land between the midfield and Marussia, making it harder for either driver to showcase their talents.

Marussia

Jules Bianchi - Average Qualifying: 19; Average Finish: 17.
Max Chilton - Average Qualifying: 20; Average Finish: 18.
Despite his 11th-hour arrival at the team, Bianchi has dominated his head-to-head with Chilton so far in the all-rookie battle at Marussia. The Frenchman heads the qualifying battle 12-0, whilst the Singapore GP was the first time Chilton has finished ahead of him all season when both have reached the chequered flag. With development seemingly stopped on the car, the Marussia is now the slowest on the grid, meaning both drivers usually find themselves occupying the final two positions making it hard for either driver to show vast differences in their averages. Bianchi's 13th place in Malaysia remains the team's highlight and could be crucial in the battle for tenth place in the Constructors' Championship at the end of the season.
