Toto Wolff has explained the issues that Mercedes faced during Free Practice 1 at the Monaco Grand Prix, with the team boss labelling the car "undriveable".
After appearing to have made progress last time out in Spain, the Silver Arrows struggled with the return of porpoising as they hit the track in Monte Carlo.
Both Lewis Hamilton and George Russell were heard to complain about the problem over the radio, and Wolff has shed some light on what is causing the difficulties.
"I think we have a ride issue," Wolff told Sky Sports F1.
"That's something that we had through the season. And this, on the bouncing, sometimes it's a combination [of things but] today it's the stiffness."

How Mercedes will approach issues with "undriveable" car
Wolff feels that the W13 remains a "good car", but that issues such as those that took effect in FP1 are making it a challenge to drive.
"It looks like our car performs, because we were quick," the Team Principal said.
"Maybe not at the end where we had the Hard tyre on and we did the long runs but, overall, I think [it's] a good car, but it's just undriveable like this."
When asked how the team will address the problems, Wolff explained: "I think work on the set-up, trying to make it a little bit more enjoyable for them."
Wolff taking positives from learnings
Following their stronger showing at the Spanish Grand Prix, Wolff remains hopeful that Mercedes can still continue to work towards being on a par with Red Bull and Ferrari.
"We're coming closer in any case," he commented.
"[We're] learning more and more, so that's positive."
