Clark and Nasir on testing results from Jerez de la Frontera admit to being surprised with the pace of the 2015 Ferrari, the challenge facing McLaren Honda and they question why Susie Wolf is a test driver. We also have Motorsports Mondial and a fresh new episode of Tech Talk with Tim.

WILLIAMS MARTINI F1 BARCELONA TEST DAY ONE.

Susie Wolff: We learnt a lot today. Carrying out some longer runs in the morning gave me experience of tyre management and it was good to get time in the FW37. The car has a lot of potential and the number of laps we completed today gave the team a lot of data. It’s just a shame I didn’t get the chance to drive the faster tyre. I got a good feeling of the car and as a driver, have learnt a lot.
