The car was driven by Romain Grosjean and Kevin Magnussen, with additional testing work carried out by Pietro Fittipaldi.

[12] Romain Grosjean retired from the race, due to a damaged wheel nut, which subsequently failed mid-race following his pitstop.

[18] At Azerbaijan, the team failed to enter Q3 for the first time in the season, with Grosjean being eliminated in Q1, coming in 17th, while Magnussen advanced to Q2, finishing in 14th.

[25] This result however, was overshadowed by a 2 mid race clashes between the drivers, which saw Magnussen force Grosjean wide at turn two, and into the asphalt run-off, causing him to lose positions dropping from 7th to 10th.

[29] Subsequently, at the British Grand Prix, the car of Grosjean was reverted to its original Melbourne specification to determine if the upgrades had failed.

[30] However, the two drivers collided early in the race with both receiving punctures and retiring, resulting in the team losing an opportunity to compare car specifications.

[33] Prior to the Belgian Grand Prix, Haas announced that the split-specification experiment would cease and both drivers would use a revised version of the package introduced on Magnussen's car in Germany, and later used in Hungary.
