Both Romain Grosjean an⛄d Kevin Magnussen will use Haas’ Melbourne-spec Formula 1 car for this weekend’s Russi𒆙an Grand Prix.

The American squad has been testing various aerodynamic configurations in recent months as it looks to get to the bottomꦰ of its performance-related issues which have hampered its 2019 campaign.

Both drivers will now switch onto the same-spec car Haas ran at the season-opener in Melbourne, with slight adjustments to compensat🐈e for a tweaked sidepജod design.

“We bring๊ the Melbourne-spec, both cars on the Melbourne-spec,” Haas team principal Guenther Steiner told media on Thursday in Sochi.

“It was planned for a long time. We now have a configuration that we do not have to change the sidepods anymore on t༒he car - we figured out that we♉ can change them.

“We have now two aero specs, the old one and the new one and we can interchange them. I think it’s part of our set-up work now but to come here we always planned to run with the Melbourne-spec because it seems t﷽o be suiting better in the simulations.”

Steiner is confident his team now understands it▨🅠s problems throughout this year and believes running the same package will only benefit its analysis.

“We are working hard and I think we now have a lot more understanding of what actually happen💝ed and what is happening,” he exp𒁏lained.

“At the moment, we are not trying anymore, we know that the drivers feel more conf🌃ident with this spec and for this track, we need this one. We get a lot better understanding of it and therefore we do this.

“We understand the lack of performance, and comparing the two has helped to get a better unders▨tanding. We know how to design it differently but we still need to do that.

“It’s not like you switch on and say ꧑‘now I will do it different and it will be fine’ because you still need to develop what you want.

“We didn’t do this on purpose, so it wasn’t a design thing. It happened and it didn’t work, so now we have to find a solution bꦯut we are clear what we have to look for.”

Asked if he feels a solution can be found before the end of the season, Steiner replied: “We do a lot of testingꦗ to analyse better where we went wrong but I don’t think we will see a solution to it.

“We will do some testing with some parts over the next races but whether it makes the car a lot better this year, I think we will try to make the best out of the car that we have 🧸got, like we have in the last races.”
