Grosjean has been at Haas for a few seasons now and has seen the teams progression. The American team finished 5th in 2018 behind midfield competitors, Renault. It will be an interesting battle to see who will come out 'best of the rest.'
When asked if the 2019 season will see the same levels of progression like previous years he said, "Yes, we are working hard on it," to f1only.fr.
"Obviously, since we do not manufacture our own parts, it takes a bit longer for some parts than for other teams, but we are really close to our partners,"
"Honestly, it's getting better and better year after year, and it's really nice to see that things have clearly changed in the last three years."
Hass' chief engineer Ayao Komatsu also spoke about the team's progression.
"It was the first year that we actually decided to develop the car throughout the season," he said.
"We are very happy with our baseline and how the team is operating, especially considering that 2018 was only our third season,"
For a relatively new team, Haas has performed well so far. It will be interesting to see if they can build on their previous years progression or if the 2019 rule changes will damage their performance.
