Grosjean: Challenge keeping up with the big boys

It may have been an incredible start to Haas' F1 career but Romain Grosjean reckons the real challenge still awaits; keeping up with pace of development.
Haas have already bagged two top-ten results in the first two grands prix of this season as Grosjean raced to sixth in Australia before following that up with a P5 in Bahrain.
It has been an unexpectedly quick start from Formula 1's newcomers, who many predicted would be in the points this season but not quite this soon.
But having now proven they can run with the big boys, Grosjean says the challenge they now face is keeping up with them as the season progresses.
"Now it's going to be our challenge to keep up with the big boys," he said.
"We've had a good start and have a good baseline. Of course, as a driver, I want more performance.
"I think there are a few more parts coming in China and then a few more after that.
"I'm very much looking forward to trying the first updates to see if they're working as they should.
"We're not a hundred percent with the car yet, so there are still a few things we can do without adding the updates."
Team boss Guenther Steiner insists Haas will continuously develop the car as they look to remain inside the points.
"It is very difficult, but we will continue to develop," he said.
"We'll continue to test in the wind tunnel and bring new developments to our car, and that will lead to gains in our aerodynamic program throughout the season.
"I think we'll bring new developments like the rest of the midfield packs are doing, or aiming to do."
