Alain Prost has admitted to having mixed feelings about Formula 1's newest team Haas.
The outfit was founded by Nascar team co-owner Gene Haas, who collaborated closely with Ferrari in order to prepare its 2016 car.
"I have mixed feelings about Haas," quadruple world champion told AFP.
"On the one hand it's 100% positive for Formula 1. As a team they are making the most of the rules but they quickly reach a limit - they will not have the ability to continue to improve.
"But it's their choice. I can also understand the reaction of some teams, like Williams, when a team like Haas is able to just buy parts left and right. After all, to make everything yourself, that's something else - it's not the same job."
Haas have picked up 22 points in the constructors' championship so far.
