Brendon Hartley is struggling to catch a break this season, this time the Toro Rosso driver will be forced to start the French Grand Prix from the back of the grid after his team were forced to change the Honda power unit on his car.
Early on during FP2 Hartley spun and when he rejoined the problems appeared and now it emerges that they were terminal and requiring replacement.
The change meant that the New Zealander went beyond the penalty-free limit in all areas, his sanction amounts to a 30-place grid drop.
Hartley told reporters on Friday night, “It was a disappointing end of the first practice day for me here in Le Castellet, as something happened with the PU in the final minutes of FP2. I don’t have the exact details yet, but we had to cut the session short.”
