Williams has not cast any doubts on the parity of equipment it receives from Mercedes, the team has stated.
A statement issued on behalf of deputy team principal Claire Williams said: “Contrary to comments made recently in the press, we refute any suggestion that we have questioned the parity of the power units provided by Mercedes-AMG HPP.
“We are absolutely confident that the power units used by Mercedes, Force India and ourselves are identical in terms of both hardware and software.
“We have an excellent professional and personal relationship with Mercedes, and our focus is firmly on continuing the good work that we have started, as we prepare for the final test in Barcelona this week ahead of the new season.
The FIA issued a directive ahead of the new season requiring manufacturers to ensure their power units “must be capable of being operated in precisely the same way” by their customers. It said the rules are intended “to ensure that all power units supplied by one manufacturer are identical in all respects.”
