Toro Rosso have officially unveiled their first car since joining forces with Honda for the 2018 season, the STR13.
Their 2018 challenger, which features the same distinctive blue and red livery of last season, was presented ahead of the first winter test getting underway in Barcelona.

The STR13 has a nose similar to that of parent team Red Bull's RB14 and wing detailing above the halo.
Toro Rosso had released a first image of the car last Wednesday after an unauthorised image was leaked on social media following the team's filming day in Italy.
Toro Rosso subsequently responded with a picture of their own and the message: "Why settle for a leaked photo, when you can have an original."
New engine suppliers Honda tweeted: "People leak photos, we leak better ones. See you at testing @ToroRosso."
Toro Rosso have swapped Renault engines for the Honda power units discarded by McLaren.
Given Honda's underperformance with the 20-time world champions, Toro Rosso have been predicted to struggle in 2018 by many F1 pundits but the team remain optimistic the exclusive partnership with the Japanese manufacturer can enable them to challenge towards the front of the field.
It is the third year in a row in which Toro Rosso embarked on a new season with a fresh engine partner after running Ferrari power in 2016.

The team have also changed drivers for 2018 for a line-up of 22-year-old Frenchman Pierre Gasly and 28-year-old New Zealander Brendon Hartley.
Although the pair drove for Toro Rosso during the final races of 2017 following the axing of Daniil Kvyat and Carlos Sainz's departure to Renault, Gasly and Hartley will be the least experienced line-up on the grid.
Between them, Gasly and Hartley are yet to start 10 F1 races or score a single point in the sport.
Toro Rosso finished seventh in last year's Constructors' Championship after being pipped by Renault for sixth at the final race.
