This shot of the STR13 with the covers off at the British GP gives us some great insight into how the team arranged their internal cooling, taking on board the saddle cooler layout on top of the airbox previously used by McLaren and likely favoured by Honda.

Toro Rosso was not on their own when it came to producing aero fins for their halo, but while most used the 20mm tolerance to control airflow on the top surface of the safety structure, they also opted to create surfaces on the underside. At the launch its fairing featured a winglet under the ‘widows peak’ to help with general airflow and also buffeting.

The team has become well known for its interesting solutions, often copied by many in the field, this area of the floor being one of them in recent years. It raised the complexity level notches a few levels further in 2018 too, utilising multiple L-shaped fully enclosed holes and an array of flaps just ahead of the tyre.

Towards the end of the season it decided to make another aerodynamic push, as this new front wing arrived for the US GP, but with limited running in Free Practice it opted to wait until next time to run it. The new design featured a shorter endplate and an additional flap at the rear (arrowed) much like other teams had introduced earlier in the season.

As part of the US GP update the team also had a revised set of bargeboards, which featured a full length vertical slot in the forwardmost element (red arrow) and new sidepod deflectors (white arrow).
