Meanwhile Ferrari have gathered quite a lot of attention having showcased their concept of the "halo" device which is likely to be used in the future for greater head protection for drivers.
An impressive 172 laps in total for Lewis and Nico today! That breaks the record for most laps set in testing (under current engine regulations)! Rosberg also set the fastest lap of the day and the 2nd fastest of 2016!
The W07 is yet to break down and its impressive to see that the car is even stronger than it's drivers who are having to test the W07 in stints to avoid injury!
The test is currently suspended for lunch time.
Nico set the fastest lap of the morning and 2nd fastest lap of Pre-Season Testing so far.
Mercedes have driven a distance of 82 laps this morning (a lap count unbeaten by any team so far this morning). Lewis will now take over for testing this afternoon. 🏁
Testing is currently underway at the Circuit de Catalunya this morning.
Nico is in the car this morning and Lewis will take over this afternoon.
Mercedes are currently 4th fastest with the most laps set (31). So far so good! 🏎
Some Flow-Viz spotted on the W07 this morning.
There were rumours that Mercedes could be running a radical new nose design today, but nothing new has been seen yet.
The first day of pre-season testing has ended with Lewis having put in a staggering 156 laps - 30km further than the first day of testing last year and over double what Ferrari, Haas and Renault managed to do.
Great work Lewis, the car will be back on track tomorrow morning in the hands of Nico Rosberg. 🏁
