It’s groundhog day for Pierre Gasly with Honda announcing they will fit his Toro Rosso with a new, latest-specification power unit in Mexico this weekend, triggering a 15-place grid penalty that will send him to the back of the starting field for the second successive race.
The Frenchman started 19th in Austin, after Honda opted to fit a fresh engine with “minor modifications” to his car and that of team mate Brendon Hartley.
On arrival in Mexico, Honda decided to put in another fresh engine because they “have a concern regarding the assembly of the one used in Austin”, according to their Technical Director Toyoharu Tanabe.
He added: “That PU has been sent to Sakura for a full inspection and, at the moment, we are not sure if we can use it again this year. Therefore, by fitting a new one here, we add one to the pool of available units for the rest of this season.”
