Toro Rosso STR10 - low-downforce rear wing

In Montreal all teams introduced low-downforce rear wings, though these are not the extreme solutions we used to see on the pre-2014 regulation cars.

That is because the current generation of F1 machines cannot afford to lose too much rear downforce, now that the lower beam wing has been banned.

One of the most interesting solutions seen in Canada was this rear wing on the Toro Rosso, with new endplates featuring only two gills at the front and top, and a very low-downforce main profile and flap.
