Honda looked to have made genuine gains with its 2024 bike when it appeared at the Valencia test last November, but that proved to be a false dawn.
HRC sits last in the constructors’ table with just eight points after the opening two rounds of the 2024 season, with Mir scoring a best of 11th in Portugal.
Honda riders occupied the last four spots on the timesheets at the end of Friday’s practice for the Americas Grand Prix, with Mir suffering a crash late to end up 20th and 2.047s off the pace.
Already admitting he was doubtful of a good showing coming into the weekend, Mir says Honda appears to be “paying the consequences” for taking the wrong development direction with the 2024 RC213V.
“Yesterday I was not very convinced about today,” he said on Friday.
“We are having some problems that, more struggles than probably what I expected after the tests in the beginning of the season.
“This problem in one track and the other and the other is not improving, we are not improving.
“I cannot really speak about what the problem is, but I think we took a direction that was not the right one and now we are paying the consequences. We must continue working.
