Today's schedule consisted of setup work ahead of the Monaco Grand Prix, in addition to the evaluation of a number of new parts Nico completed 78 laps between green light at 09:00 and lunch break at 13:00, a further 68 between 14:00 and the chequered flag at 18:00 Mercedes-Benz Power Units today completed a total of 1,717.695km

Nico Rosberg Today was a great test day for sure. The track was a little bit quicker than over the race weekend and we did many laps, so I'm a bit tired! But it's my only test during the season so it's important. Today, we tested a lot of different things - some more generally for the rest of the season and some for the next race. Monaco has very unique setup characteristics so we evaluated a few of those. The last sector here has a lot of tight corners - so it's like Monaco in a way, which is useful. The car felt very good there so I'm feeling optimistic and ready for the next race. It's in my home town, it's a legendary circuit and it should be a good weekend so I'm really looking forward to it.
