Nico Rosberg will use his frustration from the Bahrain Grand Prix for motivation when he starts the Spanish Grand Prix from pole position Sunday. The German driver finished ahead of Lewis Hamilton to give Mercedes front-row seats at the Circuit de Catalunya, with both drivers still seeking their first wins of the season in a car which has plenty of pace but has lacked durability over the first four races. Three weeks ago, Rosberg took pole in Bahrain only to finish ninth, and he is determined not to fall short again.
