F1 mid-season report: Teams

F1i looks at how each team has performed in the first half of the year and gives them all a mark out of ten as F1 embarks on a mandatory two-week factory shutdown

Mercedes: 9/10

It has been an almost faultless first half of the season for Mercedes. Itโ€™s hard to believe the defending constructorsโ€™ champions could better the levels of dominance seen last year, but it has scored more points this year than at the same stage in 2014. Ferrari looks to be a genuine threat at certain circuits, but improved reliability has seen Mercedes score an incredible six one-twos from ten races.

The only real black marks on the teamโ€™s season so far comes in the form of some poor starts - which proved very costly in Hungary - and a major strategic error in the Monaco Grand Prix which dropped Lewis Hamilton from a comfortable victory down to third place behind Nico Rosberg and Sebastian Vettel.
