Romain Grosjean has called on the Haas Formula 1 team to get to the root of its struggles after suffering what he deemed to be one of the worst qualifying sessions of his career in Mexico on Saturday.
Grosjean qualified 21st at the Autodromo Hermanos Rodriguez, finishing only ahead of Jolyon Palmer who took no part in the session after damaging his chassis in practice.
Haas has encountered a number of issues through its debut F1 season, with Grosjean making his frustration over this weekend’s setback clear.
“Starting last on the grid I think never happened to me before,” Grosjean told NBCSN.
“Probably the worst qualifying of my career. We just need to understand why it’s happening because clearly something is not right.
“The car is nowhere. I don’t know what’s happening. It was good in FP1, it was alright in the first run this morning, and after that the car has just been nowhere.
“We need to try to analyze it, because something clearly is not right. It’s enough doing miracles on Sunday [Grosjean finished 10th in Austin]. I think now we really need to understand what we are missing.
“Because last on the grid just really is not acceptable for us.”
NASCAR team co-owner Gene Haas took his new F1 operation onto the grid for 2016, with Grosjean scoring points in its first two races.
However, the Frenchman has recorded just two top-10 finishes in the last 14 races, while teammate Esteban Gutierrez is yet to score a point.
Gutierrez was also knocked out in Q1 in Mexico, finishing 17th after a spin on his final qualifying effort that also compromised Grosjean.
