Williams technical chief Paddy Lowe has revealed Red Bull outcast Daniil Kvyat has joined the list of drivers under consideration for a 2018 Formula One seat with the team.
The Grove-based outfit holds the last major vacancy on the grid for 2018 and is currently evaluating which driver to place alongside 19-year-old Canadian rookie Lance Stroll for next season. Williams handed Robert Kubica and reserve driver Paul di Resta private tests at Silverstone and the Hungaroring last month, while the team is also considering whether to retain veteran driver Felipe Massa.
Mercedes boss Toto Wolff recently suggested Pascal Wehrlein, whose future at Sauber beyond this year looks uncertain, is in the running despite a widely-held assumption within the paddock that the team's sponsorship deal with alcohol brand Martini requires at least one of its drivers to be over the age of 25.
