Now, the American-owned team have revealed a new 'driver' sitting in their car, in a nod to the time of year.
Haas reveal new driver
Magnussen and Hulkenberg have propelled the team in recent races, and a plethora of points-scoring finishes has seen the team rise to sixth in the constructors' championship, even pressurising Aston Martin in fifth.
Haas sit 40 points behind Aston Martin with four races to go, but the momentum sits with the American-owned outfit following five points-scoring races in a row.
Haas' social media team cleverly sat a pumpkin in their VF-24 car, to celebrate Halloween F1-style.
With scarily-sharp teeth, the pumpkin photos were accompanied by the caption: "Our latest driver is ready to squash the competition," in a post that appeared on the team's X account.
