Suffering a disappointing Mexican Grand Prix, Haas driver Romain Grosjean admitted that they have not figured out what was wrong with his car on Sunday, citing handling issues a major problem.
Starting the Grand Prix from the pit lane, the Frenchman only managed to gain two places, beating out the two Manor drivers, while his team-mate Esteban Gutierrez finished one place ahead of him.
The American team attempted to recover from his lackluster qualy run on Saturday and made last minute changes to his car, but it proved fruitless.
“We tried to change a few parts to analyse what was going wrong but we haven’t found the problem yet,” Grosjean explained.
“The car was nowhere. It is difficult to handle, to drive. We didn’t get anything right.
“Understeer, oversteer, you never know what you’re going to get. The car is pulling left under braking. It feels like something is weird.
“We tried to change a few things overnight but the car was not behaving the way it should. Difficult day in the office.”
