It's the start of the second week from Barcelona and 2019 pre-season testing. Mercedes has unveiled a number of new updates while Ferrari has faced issues early on in the day related to the SF90's cooling system.
What to expect from the second week of testing: It was an intriguing first week with Williams failing to really show us what they're made of and Ferrari making a serious statement. Reigning champions Mercedes meanwhile were suspect and way off the pace but we are almost certain we've not seen their full potential and probably won't until we arrive in Melbourne. Don't be surprised by a Mercedes 1-2 come Melbourne.
Williams meanwhile were somewhat of a laughing stock in week one, failing to make it out on track until day 3 of testing. They were way off the pace when they did get out but the bigger issue is they missed out on two days worth of data and testing which will be a big set back for the season opener.
Ferrari meanwhile are looking to right the wrongs of 2018 and they set the standard in week one. Leclerc looks like he's the right man to step up, getting in a considerable number of laps as well as setting some decent times. Vettel is under great pressure in 2019 as he looks to finally mount a real challenge after faltering after the halfway mark over the last two years.
Here are each of the line ups for day 1 of the second week of testing.
