Mercedes - Hamilton
Rosberg has tried a more race-oriented approach as opposed to the qualifying approach of 2014. It hasn't worked.

Ferrari - Vettel
With a car that suits him and is more competitive, Kimi simply hasn't been good enough. I think he shaded Seb in race pace early in but Vettel was settling in and is now ahead in all departments. Kimi has had some misfortune, but I think it's also true that 'you make your own luck' - there have simply been too many mistakes.

Williams - Bottas
He should be further ahead of Felipe but hasn't done well enough. He still marginally gets the nod.

Red Bull - Ricciardo
Kvyat was written off too early and sure enough he is coming into his own, and even has more points than Ricciardo! Still I think Ric is ahead, as you'd expect given his experience.

Force India - Perez
A tough one, but on balance I have to. Hulk has qualified better but lost too many points. He hasn't impressed enough on sundays.

Lotus - Grosjean
Consistent in qualifying - 15/1 is extremely impressive imo. Pastor seems to be trying a race-oriented approach but is still to finish in the top 6 whereas RoGro has a podium. Still being Pastor too much but has had bizarre misfortune too.

Toro Rosso - Verstappen
Both drivers have lost many points but clearly Verstappen is the one for the job, though the more experienced in cars Sainz heads him in qualifying.

Sauber - Nasr
Easily ahead of Ericsson on points, but also beaten by Marcus too often.

McLaren - Alonso
Narrow margin in qual for Alonso, bigger gap in races, even though Button has more points.

Manor - Stevens
Kinda by default as the 2nd car hasn't been able to be given much priority, but Stevens has still done ok.
