Grosjean mystified by VF-16 chassis problems

Nine months ago Romain Grosjean decalred that the Haas team was living the American dream in their Formula 1 debut season, but a spate of bad races in the last half of the season appear to have turned the project into a nightmare for the Frenchman.

Speaking after a woeful race weekend in Mexico, Grosjean said, "We tried to change a few parts to analyse what was going wrong but we haven’t found the problem yet.

Grosjean finished 20th and believes there is something seriously amiss with the VF-16 chassis, "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," admitted Grosjean despondently.

Teammate Esteban Gutierrez was not better off in his home race, finishing one place ahead in 19th at Autodromo Hermanos Rodriguez.
