The car’s key weakness has been rear-end entry stability, and Eddolls acknowledged that it hasn’t helped the Dutchman, who like the other F1 newcomers also faced a run of tricky street and temporary tracks in the first part of the season.
De Vries has struggled thus far to match team-mate Yuki Tsunoda, and has been under pressure from his team boss Franz Tost and Red Bull motor sport advisor Helmut Marko to raise his game.
“It's not been an easy car for a rookie to get used to,” said Eddolls. “Some drivers find it harder to adapt to one with entry instability than others.
“I wouldn't say Nyck is someone who particularly struggles with that, but for sure to try to get a set-up that suits him has been a little bit more challenging with some of those issues.”
AlphaTauri had a new rear wing in Austria last weekend, and Eddolls confirmed that a further package for Silverstone is aimed specifically at the rear stability issue.
