Ahead of the Italian Grand Prix, Mercedes’ Trackside Engineering Director Andrew Shovlin explained why Mercedes had to give Lewis Hamilton new engine components.
“That power unit [which was damaged in Belgium], we lost water pressure and he switched it off as you may have heard during the race,” the Briton said.
“That is still at HPP [Mercedes High Performance Powertrains] and there, it is undergoing some detailed checks.
“We have had other issues with other elements in the pool that haven’t taken them out of action but have certainly lessened our enthusiasm to race them.

“We are obviously desperate to avoid a DNF and reliability has been one of our strengths.”
Shovlin then explained why Monza was chosen as the appropriate track to take the grid penalty.
“Just on the balance of probability, we believe at some point during the remainder of the year, we would have been taking a penalty.
“It is why we decided this would probably be a better track to take it at given you have long straights and a better chance of overtaking.”
