The drivers' and constructors' championships after four races make pleasant reading for Mercedes. Nico Rosberg has had a serene run, becoming only the fifth driver to win the first four races of the season, to lead team-mate Lewis Hamilton by 43 points.
Mercedes has accumulated an impressive 157 points, more than double that of its closest rival Ferrari and only two shy of its tally at this point last year. But look behind the results and you'll find evidence of a team that is starting to feel the strain.
As Rosberg said in Russia, the Mercedes F1 W07 remains the car to beat.
