The VF-25 marks a breaking point with Haas’ past for many reasons. The 2025 car is the first to be created under the technical direction of Andrea de Zordo, who took over from Simone Resta last January. For the first time, the American team has decided not to adopt the updated Ferrari front suspension, opting not to deal with its many new features. Instead, they will continue with the old specification, combined with a new chassis and Toyota resources to optimize the package.
Beyond the limits
The Haas VF-25 is built around a new chassis. The team had considered reusing the 2024 chassis, which would have saved time and resources to reinvest in the 2026 car. However, track experiences during the last season highlighted limits to the development possibilities, which could not be overcome without modifying the chassis. The front suspension, however, remains unchanged. Haas decided to forgo the updated 2025 Ferrari design, as switching to the pull rod system would initially have had a negative impact on the car’s aerodynamics. Given the available resources and information, the Italian-American team was unsure whether they could compensate for the initial aerodynamic loss with the development benefits guaranteed by the new suspension, preferring to rely on the experience with the old specification to capitalize on results in the first part of the season.
The VF-25 uses the push rod system from last season, with a similar arrangement for the outer wishbones. The upper triangle features a slight anti-squat level, while the steering arm remains in front of the lower triangle. As for the rear suspension, the American team uses the 2025 Ferrari specification. The system is still a pull rod type, updated to fit a redesigned gearbox housing. However, the limited quantity and resolution of the released images force us to wait for track photos to appreciate the changes made.
Aerodynamic evolution
The renders of the new Haas appear less detailed compared to those published by Ferrari, offering few views of the 2025 car. However, leaked photos from the Silverstone shakedown last weekend confirm some similarities regarding the main lines. For instance, the side radiator intakes are an evolution of the 2024 geometry, abandoning the P-shape seen on other cars. From a three-quarter view, it is also noticeable how little the upper lip extends forward compared to the actual air intake, in contrast to the current trends on the grid.
The airscope above the cockpit mirrors that of the VF-24, with two small air intakes on either side of the central triangle. In this, Haas confirms a compromise choice, with a less centralized cooling system compared to the competition, but likely with a larger portion of the radiators in the central area compared to Ferrari. The front wing also represents an evolution, with a notably more tapered nose. However, for detailed analysis of this and other aerodynamic surfaces, particularly the floor, we will have to wait for images of the actual car.
One more ally
Other notable changes do not directly concern the car itself but the tools available for the season. The new partnership with Toyota increases the production capacity for carbon parts and metal prototyping, reducing the time to manufacture updates and spare parts. The dynamic test benches from the Japanese manufacturer will also be of great value, useful for analyzing the mechanical behavior of the package and reinforcing its reliability. Above all stands the simulator provided by the Japanese giant, an additional tool to fine-tune the VF-25 in preparation for individual Grand Prix. The 2025 car features several interesting innovations, but those behind the scenes are equally significant.
