The STR13 – Toro Rosso’s first Honda-powered car following their move away from Renault engines – is expected to be revealed in the pit lane ahead of its morning track debut.
It will be raced this season by New Zealander Brendon Hartley and Frenchman Pierre Gasly, the driver line-up with which Toro Rosso completed 2017 after the departures of Carlos Sainz and Daniil Kvyat.
Toro Rosso finished seventh in last season’s constructor standings after narrowly losing out to Renault for sixth place, 53 points to 57.
The news means only Red Bull, Force India and Haas have yet to confirm launch dates for their 2018 challengers.
Confirmed 2018 launch dates:
Williams - February 15
Sauber - February 20
Renault - February 20
Mercedes - February 22
Ferrari - February 22
McLaren - February 23
Toro Rosso - February 26
