Romain Grosjean finished the Mexican Grand Prix in twentieth, a disappointing result after finishing in the points at the United States Grand Prix the weekend before.
The Haas F1 Team driver started from the pit lane, after the team had to change the floor of his Haas VF-16 on the morning of the race. With it being different from the floor that was used in qualifying, FIA regulations stated that a pit-lane start was required. With a Virtual Safety Car triggered by the incident between Marcus Ericsson and Pascal Wehrlein, Grosjean moved up to nineteenth.
After exiting this pits, Grosjean experience lack of downforce. Combining this with the slippery track surface, the Frenchman was unable to make forward progress. He only managed to pass Esteban Ocon for twentieth, with this being the position he saw at the chequered flag.
Grosjean admits the car was very difficult to handle and to drive at the Autódromo Hermanos Rodríguez.
“We tried to change a few parts to analyze what was going wrong,” said Grosjean. “But we really haven’t found the problem yet.
“The car was just nowhere today. It was very difficult to handle and to drive. We didn’t get anything right. We’re experiencing inconsistency with lots of oversteer and understeer. I never knew what I was going to get out there. The car was pulling on the left under braking. It felt weird. It was just a very difficult day.”
