According to Williams' head of performance, Rob Smedley, his team's Mercedes-powered car has not given them any headaches in terms of reliability this season.
While Mercedes driver Lewis Hamilton started from the back of the grid in China and in P10 at the Russian Grand Prix due to MGU-H problems, Williams have managed to get both their drivers across the finish line in all four races thus far, and have suffered no engine issues.
Even Championship leader Nico Rosberg, who has won all four grand prixs this season, suffered minor reliability scares in Australia and Russia.
However, when quizzed whether or not Williams are having similar problems as the Silver Arrows, Smedley revealed that they have been fortunate enough to avoid such issues, despite running the same engine.
"So far not, I know that HPP [Mercedes High Performance Powertrains] are investigating the two Hamilton failures, trying to understand what the problem is," he explained.
"We are taking all the precaution that we can but obviously we have to be guided by HPP.
"They're currently trying to get to the bottom of that problem and we’ll just follow their lead on it really, whatever they ask us to do."
