A former executive director at Mercedes F1 has warned that the team could get worse after a difficult start to the 2024 season.
The Silver Arrows have endured a difficult few races this campaign, with George Russell's P5 at the opening race in Bahrain their best result thus far.
Russell sits seventh in the drivers' standings and Hamilton ninth; Mercedes themselves languish in fourth place.
After years of domination, the Brackley team have struggled to compete in the 'ground effect' era after winning the constructors' title in 2021, with just one win since then.
Former chief sends alarming warning
Mercedes have struggled to make significant ground in the development race since falling behind.
Now, Paddy Lowe, who served as technical executive director during several championship winning seasons from 2013-2017, has said that there are no guarantees that the team will improve.
"Therefore, there is always risk you go down an avenue that doesn't work in real life and then you have to recover, and you can see that has been the case with Mercedes.
"That is very difficult to recover simply over a matter of time. You may or may not get there.
"It may get worse. This is the nature of the sport and why it is so fascinating to watch as champions come and go.
"The 2026 regulations will be a disturbance that Mercedes are looking forward to see if they can disturb the status quo," he added.
