Kevin Magnussen believes Haas owe part of their 2018 improvements to chassis builder Dallara who have “stepped up” their game.
Haas impressed their rivals in pre-season testing with their pace and continued to do so in Australia.
Where it not for a pit stop bungle, both Magnussen and Romain Grosjean would have finished the Melbourne race inside the top ten, if not the top six.
“Dallara is a crucial part of the team and they’ve stepped up this year too,” said Magnussen.
“If you look at the car, the parts look much better this year – cleaner and better quality.
“That’s very, very important, it means a lot.
“We can design the car in CFD and in a computer, and that’s working in CFD and that’s working in the wind tunnel, but if we don’t get an actual car that was what we meant it to be, then it’s not good.
“They’ve done a really good job on their side. Hopefully they will continue, because they’re learning as well.
“It’s very good for their business being involved in this project, I’m sure they are improving not only our Formula 1 cars, but their cars as well.”
