Subsequently, at the British Grand Prix, the car of Grosjean was reverted to its original Melbourne specification to determine if the upgrades had failed. 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. Haas Team Principal Guenther Steiner later declared the car as being the strangest he had worked with, saying that even as the championship reached its mid-point, the team was still struggling to understand the car with the split-specification tests proving inconclusive. The tyre struggles and tendency for inconsistent performance were said to have an impact on the design choices for team's challenger for the 2020 season.
