Shanghai saw the first glimpse of a Formula 1 team directly mirroring a technical innovation from Ferrari, as Haas unveiled modifications to their VF-26 car. The American-owned team has adopted a flap behind the exhaust outlet, a design pioneered by Ferrari, but with distinct alterations. This development is particularly noteworthy as Haas utilizes the same powertrain as Ferrari, a factor likely limiting broader adoption across the grid, at least initially. However, another Ferrari innovation – the reversed wing, dubbed the “Macarena” – is expected to see wider replication.
The FTM on the VF-26
Haas is the first team to implement a flap behind the exhaust terminal inspired by Ferrari’s design. Team principal Ayo Komatsu’s squad is running the same rear end as the Scuderia, a configuration designed to allow for the installation of aerodynamic profiles above the rear impact structure although adhering to the 60mm distance limit from the differential. The Haas technical department, led by Andrea De Zordo, clearly saw merit in the concept and chose to integrate it into the VF-26.
However, Haas didn’t simply copy the Ferrari design wholesale. Instead, they’ve reinterpreted it. The flap on the VF-26 isn’t a direct continuation of the diffuser, meaning it doesn’t function as a virtual extension of the diffuser’s exit section. Instead, the aerodynamic element is positioned slightly further back, immediately behind the exhaust outlet. Even the exhaust outlet itself differs from Ferrari’s design; Haas has redesigned this section, adding a cup-like feature at the bottom intended to direct hot exhaust gases upwards. This subtle but significant change demonstrates Haas’s commitment to optimizing the airflow for their specific car configuration.
The “Macarena” is Copyable
While widespread adoption of the exhaust flap appears unlikely, the reversed wing – the “Macarena” – presents a different scenario. With no specific regulatory restrictions preventing its replication, Ferrari anticipates that competitors will soon develop their own versions. The immediate priority for Ferrari is to evaluate the effectiveness of the wing in China, although the Shanghai International Circuit isn’t considered a particularly demanding track for energy management, meaning the full benefits might not be immediately apparent.
The VF-26, driven this season by Esteban Ocon and Oliver Bearman, represents a significant step for Haas as they aim to improve their performance in the 2026 Formula One World Championship. The team’s willingness to adopt and adapt Ferrari’s technology underscores the close technical relationship between the two outfits. It’s a strategy that could pay dividends if Haas can successfully integrate these innovations and translate them into on-track speed. For fans, it’s a fascinating example of the rapid pace of development and the constant search for marginal gains that define modern Formula 1. The interplay between Ferrari’s innovations and Haas’s implementation will be a key storyline to watch as the season unfolds.
Understanding these aerodynamic adjustments requires a bit of background. In Formula 1, managing airflow is paramount. Teams are constantly seeking ways to optimize the flow of air over, under, and around the car to generate downforce (which improves grip) and reduce drag (which increases speed). The exhaust flap and the reversed wing are both attempts to manipulate airflow in a way that enhances these characteristics. The exhaust flap, in particular, aims to harness the energy of the exhaust gases to create a more efficient airflow pattern. The reversed wing, meanwhile, is designed to manage turbulence and improve overall aerodynamic efficiency.
The Haas VF-26, powered by a Ferrari O676 turbocharged 1.6 liter V-6 Hybrid engine, also features a carbon-fiber and honeycomb composite chassis, independent front and rear suspension with ZF Sachs/Öhlins dampers, and an eight-speed semi-automatic gearbox. The car weighs 770 kg including the driver. [1] These specifications, combined with the aerodynamic tweaks, represent a comprehensive effort to maximize performance in the upcoming season.
Next up for the teams is further testing and refinement as they prepare for the next race. The data collected in Shanghai will be crucial in determining the effectiveness of these new technologies and guiding future development efforts. Fans can stay updated on the latest developments through official team announcements and race coverage on major sports networks.
