Grosjean sure Dallara fixing Haas problems

Jul.1 - Romain Grosjean has defended Haas' chassis-making partner Dallara, after a series of wing failures in 2016.

"We have made serious efforts to stop this problem so hopefully it will not happen again," the new American team's French driver, having criticised Haas following the most recent front wing failure, said in Austria.

Haas is unique in F1, having allied strongly with Ferrari but also the Italian chassis maker Dallara for the design, development and production of its first car.

Dallara was last involved in F1 with the now defunct Spanish team HRT.

"Dallara continues to learn," Grosjean said. "It is one thing to build a GP2 car, but in formula one the speeds and the loads are higher and it takes time to have the right processes.

"I'm sure gradually this is being resolved," he added.

Regarding Haas' 2016 car, team boss Gunther Steiner said the team has now stopped developing it in order to work on the 2017 model for the new rules.

Grosjean commented: "I think all the teams have done the same, or will do in the near future.

"Our team is new in the championship and it was important to have a good foundation but in the second year it is necessary for us to do more," he added.
