The STR13, was set to be revealed to the next Monday on the first morning of pre-season testing & today it made its track debut at a wet Barcelona circuit in the hands of Brendon Hartley.
On Wednesday 21st February 2018, images of the car were leaked online & Toro Rosso was forced to share an official photo of the STR13 on Twitter.
The team switched to the Japanese manufacturer from Renault for 2018 & will now be powered by the Honda RA618H engine. The photo reveals a similar livery to the one introduced by Toro Rosso last year.
The STR13 was fitted with the halo device, which included a small slotted gap trim similar to that seen on the new Sauber.
The car will be raced this season by Hartley and Pierre Gasly.
