Williams has broken Formula 1 curfew rules to change Robert Kubica’s chassis overnight at the German Grand Prix after discovering damage to the Polish driver’s car “which was ♊not repairable𓆉 at the track”.

Speaking after Friday practi🅘ce, Kubica was left frustrated by breaks to key parts on his Williams – running its upgrade package for back-to-back tests – which compromised his running.

Williams has opted to switch the Polish driver to the team’🍌s spare chassis for the remainder of the German GP but will still use all the new parts delivered for this weekend which will also be installed on teammate George Russell’s car for FP3.

“We will have to revise everything and fix some parts in order they stay attached to the car, it is tꩲhe second weekend in a row that som🃏ething is breaking down,” Kubica said.

“When you leave the garage and already on installation lap [there are issues] you are compromised… it was very important for us to do our progra🃏mme, which we set up, but unfortunately we were influenced by this straight away, so not an easy day.”

It marks the second time Williams has had to reve🎐rt to a spare chassis during a race weekend in 2019 after Russell sustained heavy damage during FP1 at the Azerbaijan Grand Prix after hitting a loose drain cover.
