Just over three weeks before Melbourne, the teams are preparing for the second, and penultimate, pre-season test.

As attention turns back to Spain, this time to the circuit de Catalunya, the teams have been preparing in their own ways.

Valtteri Bottas spent Monday in the Williams simulator as part of his preparation, whilst at Enstone Romain Grosjean has been carrying out similar duties.

McLaren has taken full advantage of the rules that allow two days for promotional events each year, Jenson Button putting further mileage on the new Honda-powered car, teammate Fernando Alonso in action for the Woking team today.

Meanwhile, Mercedes is celebrating the fact that it is the first F1 team to attain one million followers on Twitter. So much for Bernie Ecclestone’s claims about social media.

All nine teams will be on duty at Barcelona when this week's test gets underway on Thursday, though Force India will be using its 2014 car.
