Formula One returned last week for the first four days of winter testing and this week, the second session is underway.
All ten teams that will enter the 2018 Formula One World Championship have now showed off their cars in testing in Spain.
The weather has so far offered everything, sun, rain and even snow.
Barcelona in early March might not offer the hot humid climates that the teams will face during the course of the 2018 campaign, but what did we learn?
Haas
On the surface there aren’t many changes at Haas. The driver line-up remains the same and so does the power-unit with close ties with Ferrari.
In 2017, Haas had a quick car at times and at others, it proved to be a bit of a handful to drive.
But over the first four days in Spain, the American team managed to set some good times and maybe give some optimism to the team that they can stay ahead of Sauber Alfa Romeo and maybe challenge a little but further up the grid.
Kevin Magnussen’s time of 1minute 20.317s on day four on the supersofts saw Haas set a time quicker than Renault, Williams, Toro Rosso, Force India and Sauber.
Whilst their 187 Laps, was not terrific, their final day improved their tally and still kept them ahead of Force India in terms of mileage.

?I think it?s a good end to a difficult testing session. The first few days were compromised by the weather, but today we got 96 laps in. We made some progress and we understand the car a little bit better. Next week we need to start from where we are now, get better and then work toward being ready for Australia.?
