Russell believes in the Mercedes W15: "It's not the diva it was"

It was a year ago, also in Bahrain. The test was barely underway when Lewis Hamilton knew enough: 'This is not a winning car,' the seven-time world champion realised then. In hindsight, he was right: with the W14, the German team did finish second among constructors, but a Grand Prix victory did not materialise. At least with the W15, Mercedes hope to be more competitive.
