Toto Wolff, Mercedes’ chief executive, has explained why Lewis Hamilton had to switch engines at the Turkish Grand Prix, and he isn’t ruling out another switch and grid penalty before the season’s finale.
Last weekend’s race saw Hamilton switch to a new Internal Combustion Engine (ICE), which dropped him ten positions on the field after he topped qualifying. He eventually finished sixth, but he had given up his championship lead to Max Verstappen, who he now trailed by six points with only six races remaining.
The Englishman had previously stated that he hoped to finish the season without installing a new engine, but Wolff underlined that the choice made in Istanbul was not tactical.
“We had to do it,” the team boss told Sky Sports F1. “We saw some data on the Internal Combustion unit that didn’t look very promising and a DNF is a total killer for the championship.”
Wolff added: “We’ve seen over the course of the season that we’ve had some little gremlins that we weren’t completely sure where they came from and how much performance they could potentially cost.
“So we’d rather have a new engine in the pool and that we understand that can possibly go longer.”
“I think we understand much better now where the root cause lies and it’s something that can happen from time to time if you just have a material issue, a batch problem and these are the things you need to consider,” explained Wolff.
