At Mercedes, Toto Wolff admitted that the big update package brought to the Canadian GP did not deliver the gains expected by the team. Despite the strong performance in Montreal, the team principal acknowledged that the data seen on track did not fully match internal projections, increasing doubts about the real impact of the novelties on the W17.
Meanwhile, the FIA confirmed an important technical change for the Monaco GP. The entity decided to bring forward the application of a regulatory change that eliminates a loophole exploited by Mercedes in its power unit. The measure takes effect immediately and ends a discussion that had been raising questions among manufacturers since the preseason.
At McLaren, Andrea Stella confirmed that the team intends to use the new front wing again in Monte Carlo. The component had been abandoned back at the Canadian GP after not delivering the expected performance during initial tests, but the team believes that the Monaco layout can offer a more accurate evaluation of the update.
