We look at how the drivers are faring in their intra-team qualifying and race battles in 2015 at the midpoint of the season.
Please note: For the purposes of this feature a driver is awarded one point if they beat their team-mate in qualifying and with the same formula applied to the race results.
The results are taken from the official FIA classification and if both drivers retire from a race the score is given to the driver classified higher by the governing body.
A rather one-sided fight at Mercedes this season has seen Lewis Hamilton all-but wrap up the 2015 qualifying prize already.
After surprisingly losing the title of the quickest man over a single-lap to Nico Rosberg last year, only once has Hamilton not been on pole this season.
Starting from the front has thus put him in the best position to convert those qualifying results into points on a Sunday, where Hamilton also enjoys a healthy advantage over Rosberg.
After a slow start to life at Red Bull, Daniil Kvyat is starting to show the speed that led those in charge of the team’s junior programme to rate him so highly.
He now heads Daniel Ricciardo in the race battle after a run of four intra-team wins in five races between Monaco and Hungary.
Ricciardo still holds the lead on a Saturday thanks to four successive wins at the start of the season, but the gap is closing after Kvyat topped the qualifying fight in four of the last six races.
Arguably a more one-sided fight than at Mercedes, Sebastian Vettel has established himself as the clear number one during his first 10 races at Ferrari.
A comfortable 8-2 lead on both Saturdays and Sundays has heaped the pressure on Kimi Raikkonen to start delivering, or the Finn could be facing losing his seat.
Despite being regarded as one of the hot properties in F1, Valtteri Bottas has been unable to match Felipe Massa in qualifying this season.
That pace over a single-lap will be a concern for potential employers, with Ferrari being one, but his race-craft has proved more impressive and the Finn has overcome his qualifying woes to edge out Massa on a Sunday.
The fight at McLaren has perhaps been tighter than many anticipated between former world champions Fernando Alonso and Jenson Button.
The Spaniard holds a narrow Saturday advantage, but that is to be expected given Button has never been regarded as a strong qualifier.
The grid positions haven’t held Button back, though, as the Briton has been classified ahead of Alonso in five of the eight races the pair have both started in 2015. However, it should also be pointed out that on the two occasions when both MP4-30s have made the chequered flag, Alonso has been the man ahead.
Lotus sees the most one-sided fight on the grid with Romain Grosjean enjoying a clear advantage on Saturday and Sunday in 2015.
Already boasting a reputation in some quarters as a pay driver, his inability to match Grosjean has not helped Pastor Maldonado’s stock rise this season.
There is a dramatic split at Force India between the Saturday and Sunday fortunes of Nico Hulkenberg and Sergio Perez.
Hulkenberg has dominated the qualifying battle, showing supreme pace over a single-lap. However, he hasn’t always been able to convert that on a Sunday, with Perez the man delivering the race performances. Saying that, the Mexican hasn't finished ahead on the road since Monaco.
Despite all the focus being on Max Verstappen it is the man in the other Toro Rosso who heads the battle on Saturdays and Sundays this season.
Carlos Sainz has flown somewhat under the radar in his rookie campaign, but has regularly been ahead of Verstappen. That, though, should be expected given his extra experience in the junior categories.
In the battle at the back beating each other takes on an extra significance for Will Stevens and Roberto Merhi with little chance to fight other cars given the pace of the Manor.
With the head-to-head only starting in China when both cars raced for the first time, Stevens got off to a flyer, rocketing ahead in both the qualifying and race battle.However, recently Merhi has started to turn the tide, closing the gap to make the Manor fight the tightest on the grid.
Despite Marcus Ericsson having an extra year of F1 experience, Felipe Nasr is the one who leads the fight at Sauber this season.
The opening six races were almost a whitewash for the Brazilian was he won all but one of the qualifying fights and came out on top every Sunday. In recent weeks Ericsson has closed the duel, but Nasr still holds the advantage.
