Romain Grosjean's eye-catching drives in the opening two races of the Formula One season justify Haas' decision to recruit him for their maiden campaign, according to team principal Gunther Steiner.
A sixth-place finish in Australia was followed by fifth in Bahrain, with Grosjean voted the overall 'driver of the day' on both occasions.
That unexpected early form sees Grosjean sitting fifth in the drivers' standings, while Haas top the likes of Toro Rosso, Force India, McLaren and Renault in the constructors' championship.
Grosjean is responsible for all 18 of Haas' points so far and his team could not be happier.
"I think he has paid for himself already," Steiner is quoted as saying by Autosport. "We needed a known quantity.
"If we had someone else, a pay driver, maybe we would not be where we are. We would question ourselves, 'is the material good enough'? 'Is the car good enough?'
"We know now because he pulled it off. We know now where we are.
"That is what you want to achieve with getting a driver of his calibre."
And Steiner hailed Grosjean's overall attitude and contribution to making Haas a success.
"He has been important not in the last few races but across the board," he added.
"When he says the car is good or as good as what I had before, it gives you confidence.
"We look at him when we ask where are we? Esteban [Gutierrez] is doing a fantastic job as well. It's a very good combination."
