Like all teams, Haas is obliged to undertake its own chassis and bodywork development.
However, within the scope allowed by the rules, the US-owned outfit purchases many mechanical items from Ferrari that have an impact on the overall car layout and aerodynamic concept, including the gearbox, rear suspension and cooling systems.
Inevitably that means that Haas has to stay close to Ferrari’s general aerodynamic approach.
Steiner acknowledged that the team is reviewing alternative concepts but stressed that at the moment there are no plans to make a dramatic change.
“You always try, and we are trying different concepts, but you cannot jump completely to what Red Bull is doing,” he said.
“Because you've got your chassis, your cooling installation, your radiator installation, so you cannot jump. You try to do more going that way.
“And obviously, I think everybody's trying to go to test something. But until we are 100% sure that that is a step forward, why would you go there?
“Maybe for next year, we go there. But at the moment, there is no panic reaction to go there. Because I think our car in the midfield is still pretty strong.”
