Canadian Formula 3 driver and son of Billionaire Lawrence Stroll has reportedly signed for Martini Williams Mercedes as either test or development driver for the 2016 season. With current test driver Susie Wolff announcing her retirement from racing at the end of this month and development driver Alex Lynn a contender to replace Adrian Sutil as reserve for the British squad, a potential opening for the 17 year old racer could be available at Grove next year. According to the BBC, sources at Williams suggest Stroll's role will be separate from that of Williams' reserve driver, whose job is to provide cover for the race drivers and should include both simulator work and driving duties in older spec Formula One cars that fall outside of the testing regulations in force within Formula One. Stroll's position and title - which is likely to be either test driver or development driver - are to be confirmed later this month. It is understood by the BBC that a "significant financial contribution" will be made by Canadian billionaire Lawrence Stroll in order to aid Lance's progression into the premier category with the Williams team. Stroll has shown some serious promise in his rookie European F3 season in 2015 with one victory and a further six podium positions en route to 5th in the final standings against some seriously talented young drivers. Backing up this result are previous championship victories in the Toyota Racing Series New Zealand (2015) and Italian Formula 4 Series (2014) proving that despite undoubted financial advantages this young driver might actually bring more to the Grove-based team than just cash and could prove to be one to look out for in the future. Stroll is part of the Ferrari Driver Academy and the second youngest driver to be signed to a Formula One team after one Max Verstappen, who has more than proven that age is no barometer of talent.
