Measuring the 2013 team-mates

As Formula 1 nears the mid-point of the season, we examine how the drivers have fared in their intra-team battles during the opening seven races of the 2013 campaign.

Mercedes
Nico Rosberg: Average Qualifying: 4; Average Finish: 5.
Lewis Hamilton: Average Qualifying: 3; Average Finish: 5.
Back-to-back poles coupled with a strategy blunder causing Nico Rosberg to miss out on Q3 in Germany mean Lewis Hamilton edges ahead of his team-mate on single-lap pace. Not only does Hamilton lead Rosberg 6-3 in qualifying stakes, but the 2008 World Champion has the joint lowest starting position of any driver along with Sebastian Vettel - 2.778. However, the Mercedes team-mates are inseparable on race pace, with Rosberg's stats boosted by two victories this season. Sauber
Nico Hulkenberg: Average Qualifying: 12; Average Finish: 11.
Esteban Gutierrez: Average Qualifying: 17; Average Finish: 14.
After an ultra-difficult start to his rookie season, Esteban Gutierrez has managed to close the gap to his team-mate slightly in qualifying in recent weeks. Nevertheless, he remains a long way behind on race pace with gap widening from two to three places after Hulkenberg's points finishes in Britain and Silverstone. Force India
Paul Di Resta: Average Qualifyng: 12; Average Finish: 8.
Adrian Sutil: Average Qualifying: 10; Average Finish: 10.
Two lamentable Q1 exits in Monaco and Canada saw Paul Di Resta slip behind Adrian Sutil in the qualifying standings at Force India. The Scot's Silverstone result is not included having been disqualified from the session, but had his fifth-place stood, Di Resta would still remain two places behind his team-mate. However, the Scot's race pace continues to be strong, helping him maintain his Sunday advantage, in what looks like being one of the most intense battles on the grid in 2013. Williams
Pastor Maldonado: Average Qualifying: 16; Average Finish: 14.
Valtteri Bottas: Average Qualifying: 15; Average Finish: 14.
Valtteri Bottas started the season as the surprise package of 2013, outperforming the much more experienced Pastor Maldonado in both qualifying and the races. However, the Venezuelan has recently started to close the gap, moving level on average finishing position, whilst the Finn's outstanding third in difficult conditions in qualifying Canada is all that keeps him ahead on Saturday pace. Toro Rosso
Jean-Eric Vergne: Average Qualifying: 13; Average Race: 10.
Daniel Ricciardo: Average Qualifying: 10; Average Finish: 12.
After the wet conditions for qualifying in Monaco and Canada allowed Jean-Eric Vergne to close the gap to Daniel Ricciardo, the Australian has searched ahead once more with fifth and sixth places at Silverstone and the Nurburgring respectively. He now leads Vergne 6-3 in qualy. Whilst Ricciardo may have unable to retain those spots come race day, his team-mate failed to finish on both occasions whilst running further down the order, thus preventing Vergne from falling behind in the average finish column. Caterham
Charles Pic: Average Qualifying: 19; Average Finish: 16.
Giedo van der Garde: Average Qualifying: 20; Average Finish: 18.
Charles Pic has edged ahead once more on in qualifying, partly helped by Giedo van der Garde picking up a grid penalty at Silverstone. On a Sunday, the Frenchman's additional experience shows, with his 14th Malaysia the team's best result of the season. Marussia
Jules Bianchi: Average Qualifying: 19; Average Finish: 16.
Max Chilton: Average Qualifying: 20; Average Finish: 18.
Despite his 11th-hour arrival at the team, Bianchi has dominated his head-to-heads with Chilton so far in the all-rookie battle at Marussia. The Englishman is yet to out-qualify or finish ahead of his team-mate when both have reached the chequered flag, and the Sunday gap between the pair has widened in recent weeks. Bianchi's 13th place in Malaysia remains the team's highlight of the season and could be crucial in the battle for tenth at the end of the season.
