Esteban Gutierrez has urged Haas to experiment more throughout 2016 after admitting that they made “quite a conservative” approach to the Chinese Grand Prix.
Haas have made steady strides into the Formula One scene this campaign but suffered their first weekend outside of the points in Shanghai last time out.
Former Lotus man Romain Grosjean has been the star man with a sixth place finish at the season-opener in Australia before coming home fifth in Bahrain.
Gutierrez has not enjoyed the same success having been forced to retire on the opening two weekends before finishing 14th in China, while Grosjean had to settle for 19th.
The Mexican believes the VF-16 has already proven to be a strong vehicle in the first few weeks of the campaign and feels they need to continue to get the best out of it.
The former Sauber man has called on the American team to “experiment more” to ensure they can maximise their positive start to life.
Gutierrez said: “There’s still a lot to work on, it’s part of that which we are missing – we need to experiment more, to try different things.
“I have to say that our set-up is still quite conservative at the moment.
“We still don’t know exactly where we are or are 100 per cent confident that this is right so we can expect to have these type of weekends where our car isn’t performing at the maximum.
“But the good news is that we have a good base and we’ll work on it at the next events.”
