Some, such as Poland's Robert Kubica and Britain's Paul di Resta, are experienced racers seeking a comeback after years away while others are youngsters seeking redemption or a lifeline. Massa has now been ruled out after he told fans on social media that he was retiring at the end of the season. Germany's Pascal Wehrlein, a 23-year-old prospect, can be included in the category of those with talent but on the wrong side of circumstances. Williams use Mercedes engines and could expect a discount on them for taking Wehrlein -- depending on how committed Mercedes are to him. "What's most important for the team is to pick a driver lineup that will give us the best performance and most exciting racing potential," Lowe said last month.
