Toro Rosso has revealed the first image of their 2018 Honda-powered car that it will use in the 2018 Formula 1 season.
Kiwi driver Brendon Hartley gave the STR13 its track debut at a wet Misano circuit overnight.
A full reveal will take place on Tuesday before the first Formula 1 winter test in Barcelona but Toro Rosso posted an image of the new car on their Twitter account.
The car carries a similar livery to the one used in 2017 but was fitted with the controversial halo that included a small slotted gap similar to the one used by Sauber.

Hartley was pleased to get behind the wheel and was happy with its performance.
"Finally got to put my racing onesie and slippers back on today," Hartley posted on Instagram.
"We had our filming day at a very wet Misano in our new TR13. The new girl ran super smooth."
Toro Rosso will be powered by a Honda engine after the Japanese manufacturer replaced Renault at the end of 2017.
