Haas VF-18

The Haas VF-18 is a Formula One car designed by Italian manufacturer Dallara for the Haas F1 Team to compete in the 2018 FIA Formula One World Championship. The car was driven by Romain Grosjean and Kevin Magnussen and made its competitive début at the 2018 Australian Grand Prix.

Design and development
The focus of the VF-18's design was to produce a more stable chassis than its predecessor, the VF-17, with the aim of building a car capable of producing more consistent performances between rounds. To do this, Dallara worked to reduce the weight of the chassis as much as possible, allowing Haas more freedom in using ballast to influence the car's weight distribution.

The car was subject to scrutiny following its performances in pre-season testing and free practice sessions at the 2018 Australian Grand Prix. Questions were raised over similarities between the VF-18 and the Ferrari SF70H, the car entered by Haas' partner Ferrari in as the sporting and technical regulations ban the use of "customer cars", or cars developed by one constructor and sold on to another team. Team principal Gunther Steiner dismissed the claims, responding to critics by arguing that the team had only purchased parts from Ferrari that the FIA had approved for sale.

Season summary
The VF-18 is Haas' most successful car as of March 2024 with 93 points to its name. The team achieved their best-ever combined result with Grosjean and Magnussen finishing fourth and fifth respectively during the Austrian Grand Prix, which coincidentally was their 50th grand prix entered.

This was the first Haas car to achieve a fastest lap, courtesy of Magnussen at the Singapore Grand Prix.
