United States Grand Prix – Both Toro Rossos of Pierre Gasly & Brendon Hartley will have to start from the back of the grid again after the team elected to fit their cars with new Honda power units.
It’s been a trying couple of weekends for the two drivers, after Honda brought out their new and improved Spec C engine for the Russian Grand Prix. While it wasn’t used for the race in Sochi, the change of power units meant both drivers started from the back of the grid. They were then used for the Japanese Grand Prix, the manufacturer’s home race two weeks ago.
For this weekend, Honda have chosen to fit another set of fresh engines to the cars, with their technical director Toyoharu Tanabe confirming: “On both cars, the new units will feature minor modifications to the specification when compared to that used in the Japanese Grand Prix. After examining the power units used in Suzuka, we had some concerns and so we have decided to make these changes, which we believe is the best strategy for Scuderia Toro Rosso Honda for the remaining races of the season.”
Pierre Gasly’s car has already been fitted with a new combustion engine, as well as new MGU-H, MGU-K, and turbo, while Brendon Hartley will take a fresh engine at some point before qualifying.
Toro Rosso are essentially acting as test mules for Honda at this point, ahead of the teaming up with senior squad Red Bull Racing next season.
