Ferrari SF-26: Power unit 067/6 impresses with energy management and new setups. The Ferrari SF-26’s 067/6 power unit shows promising performance in early testing.

Although the vertical aerodynamic load generated by the underbody is clearly reduced—Ferrari estimates place it between fifteen and twenty percent—the preliminary data collected in Spain suggest that the new-generation cars benefit from less complex setup adjustments.

This simplification eases the tuning process, even though the cars display a noticeably different dynamic behavior. In high-speed corners, such as turns 3 and 9, the lack of downforce is tangible and inevitable. However, lap time construction follows distinct strategies, leveraging alternative performance advantages.

Foremost among these is the torque delivered by the new power units, providing enhanced support to the drivers, particularly in the third and fourth phases of a corner. This segment, however, requires optimal energy management from the sole motor generator, the MGU-K, which recovers energy kinetically.

During Ferrari’s opening day of testing, despite adverse weather conditions affecting the SF-26 program, the team focused on data acquisition related to energy usage—a critical area for distributing the power unit’s output as efficiently as possible.

The analysis phase goes beyond simply managing battery storage and delivering 475 horsepower. In fact, there are numerous new engine mappings that drivers must interact with carefully. This is a true learning process, aimed at validating theoretical insights developed over recent months at the factory using the simulator.

In short, a substantial amount of power must be managed intelligently to maximize performance. Early feedback from Ferrari is very positive. As anticipated in recent weeks, the Scuderia’s satisfaction with the work done on the power unit was already well known.

The first two days of on-track testing have provided a welcome confirmation, further supported by direct feedback from Haas and Cadillac: the 067/6 power unit has shown no major issues, and the work program is proceeding as planned, at least for now. This was expected news, fully reinforced by the team’s positive outlook on its performance.

As the SF-26 continues to rack up mileage, the focus will shift even further toward refining these complex electronic maps to ensure the power delivery is as seamless as possible for the drivers. While the loss of aerodynamic grip remains a challenge for the engineers, the sheer brute force and reliability of the 067/6 engine suggest that Ferrari has a potent weapon at the heart of its 2026 campaign. With the correlation between the simulator and the track appearing to hold up, the team can move into the next phase of testing with a high degree of confidence in their mechanical foundation.
