A shot of the STR13 leaked by... Toro Rosso!

Toro Rosso took its new STR13 for a shakedown spin at Misano this morning, taking advantage of the 100km maximum mileage 'film day'.

While the team teased its new car in a couple of videos in which it could be heard but not seen, someone unfortunately leaked a picture of the STR13 in action.

The image prompted the team to simply post a - much better - shot of its own on Twitter!

It was clearly a wet shakedown for the Honda-powered car at Misano, and its drivers, Pierre Gasly and Brendon Hartley. It was apparently a clean run however, with no engine issues to report, fortunately.

Toro Rosso will officially unveil the STR13 in Barcelona next Monday morning, just before pre-season testing kicks off.
