Nico Rosberg claimed victory in the Monaco Grand Prix 30 years to the day after father Keke did likewise, but had to endure two safety cars and a red flag before returning Mercedes to the top of the podium.
The German also shrugged off pre-race controversy about a three-day tyre test Mercedes conducted on behalf of Pirelli immediately after Barcelona to lead from start to finish, managing his rubber as well as anyone when he needed to, and always seemingly able to open a gap over his pursuers.
The victory made the Rosbergs the first father-son combination to triumph on the streets of the Principality, and allowed Nico to go one better than the second place he took behind Mark Webber a year ago.
The race began with a grid shuffled by accidents on Saturday morning, leaving Felipe Massa at the back and Romain Grosjean further down than his Friday pace would have suggested, while rain on Saturday afternoon helped catch out Paul di Resta, leaving the Scot adrift of the top ten spot he might have expected.
Fortunately, despite the unusual order, the entire field managed to navigate its way through Ste Devote without incident, although Sebastian Vettel raised heart rates at Mercedes by attempting to force his way between the front row pair of Nico Rosberg and Lewis Hamilton. The Briton held firm around the outside, however, and the front of the pack continued in grid order.
The opening lap wasn't entirely free of contact, however, with Pastor Maldonado already having lost part of his front wing before he was collected by Giedo van der Garde on the way down to Loews. Both pitted at the end of the lap, but Adrian Sutil or Jenson Button, who also made minor contact a little further around the corner, were able to continue unaffected.
Vettel remained feisty throughout the opening laps, looking for a way past Hamilton on several occasions, only to be rebuffed by the Mercedes man, while Kimi Raikkonen had Fernando Alonso showing him similar levels of attention and the two McLarens found themselves squabbling over the same piece of tarmac at the chicane, resulting in Sergio Perez, who was forced to cut the corner, having to hand the place to team-mate Button.
Despite the various incidents, the first retirement only arrived on lap nine, and it wasn't down to contact as a seized gearbox forced Caterham's Charles Pic to a fiery halt at the entry to the pit-lane. With no debris on track, however, there was no need for the safety car, and racing continued with Rosberg holding a 1.5secs cushion over team-mate Hamilton.
