6 — Toro Rosso’s low-downforce rear wing
Like most teams, Toro Rosso installed a low-downforce rear wing with a more horizontal profile in Canada. Therefore, the central support pillar, the DRS mechanism, and the wing’s endplates have all been altered.
The two vertical gills at the top and the two horizontal dents at the front of the endplates have been altered with a view to reducing drag on the outer edge of the rear wing. This in turn helps increase top speed, an area where Renault has been struggling compared to its rivals. Despite these evolutions, Carlos Sainz, who was the fastest Renault-powered driver through the Montreal speed traps, remained 7kph slower than Romain Grosjean’s Mercedes-powered Lotus in a straight line.
