Toro Rosso has given its strongest indication yet that Kiwi Brendon Hartley will drive fulltime with the team in Formula 1 next season.
Hartley is contesting his second successive Formula 1 race this weekend in Mexico after receiving an out-of-the-blue call-up a fortnight ago.
The 27-year-old filled in for Pierre Gasly last weekend while the team opted to keep him at the expense of Russian Daniil Kvyat for this weekend's round in Mexico City.
Team boss Franz Tost was quizzed about the decision to have the pair of inexperienced Formula 1 racers contest the remaining rounds this year at a press conference after practice this morning.
Tost's reply clearly suggests Hartley will have an extended opportunity in the sport's premier category.
