As anticipated by numerous paddock insiders, including us at ScuderiaFans.com, Ferrari will use the Austrian Grand Prix weekend to introduce the first of the two power unit upgrades available under the ADUO framework in 2026. According to the latest reports, the SF-26 will also debut a new fuel specification, representing an evolution of Shell’s original product.
Austrian GP: will ADUO be enough at Spielberg?
The Red Bull Ring has always been considered a power-sensitive circuit. The three long straights spread across the first two sectors, together with the shorter straight between Turns 8 and 9, place enormous emphasis on energy deployment management.
Minimising rear-wheel slip will be essential on a circuit that is already naturally rear-limited, even more so with the current generation of Formula 1 cars, which tend to exhibit more oversteer characteristics.
The SF-26 has occasionally shown balance-related weaknesses throughout the season, often appearing limited by rear-end stability. However, Ferrari’s aerodynamic development programme has been heavily focused on that area, and the car now appears considerably more stable at the rear. This suggests that many of the earlier issues may have been linked primarily to software management rather than aerodynamic shortcomings.
Ferrari has invested significant effort into optimising energy deployment, conducting valuable work during the Monza filming day and subsequent testing sessions at Fiorano, both of which proved particularly important for Lewis Hamilton.
The British driver struggled more than anyone during the opening races of the season with an unstable rear end, caused by unusual tyre overheating, power delivery challenges and a driving style that had not yet been fully adapted to the characteristics of the SF-26.
Those difficulties were further complicated by the brake issue that only became widely discussed in recent weeks. The Carbone Industrie brake components strongly favoured by Lewis Hamilton reportedly provide a more consistent response, particularly in cooler conditions, while also helping generate tyre temperature more effectively than alternative solutions.
Combined with ongoing work on software mapping and wheel-rim development—another major focus area for Ferrari in 2026—these improvements contributed significantly to the performance seen in Barcelona.
The upgrades introduced at the Circuit de Barcelona-Catalunya also delivered an important increase in front-end downforce. Barcelona is traditionally a front-limited circuit, placing particular emphasis on front-axle management and tyre energy control. Ferrari’s advantage throughout the weekend was evident from qualifying onward and, at times, remarkably dominant.
The SF-26 now appears to have largely addressed its tyre overheating issues thanks to a major aerodynamic package designed to optimise airflow from the front wing towards the rear of the car while shielding it as much as possible from the turbulence generated by the wheels.
As a result, the car has become more predictable and operates effectively across a wider performance window. Nevertheless, with the current tyre compounds, avoiding thermal degradation remains a constant challenge, and temperatures approaching 30°C in Austria will once again place tyre management under the spotlight.
Austrian GP: thin air could become a decisive factor
It is well known that Ferrari’s power unit operates within a higher temperature range than most of its rivals. This characteristic allows the team to adopt a more efficient approach to cooling management and radiator sizing.
In Barcelona, the SF-26 featured one of the most tightly packaged bodywork configurations on the grid, delivering an additional advantage in aerodynamic efficiency.
Austria’s altitude could become a key variable. At Spielberg, the thinner air contains less cooling capacity per cubic metre, increasing the strain on every car’s cooling systems.
Mercedes, which already encountered battery temperature concerns in Barcelona, could once again find itself under pressure. However, Kimi Antonelli has already expressed confidence regarding the situation while highlighting the importance of the Austrian weekend.
The succession of long straights in the opening sectors will place considerable stress on energy management systems, recreating conditions that have traditionally suited the Mercedes power unit throughout the season. The same applies to Overtake Mode performance during race conditions, where efficiency will be tested extensively.
Mercedes will not be Ferrari’s only rival. Red Bull is expected to introduce a significant upgrade package for the RB22, including a weight reduction programme. McLaren, meanwhile, typically performs strongly in hot conditions, making it another serious contender at the front.
If the FIA formally approves Ferrari’s ADUO-derived upgrade, the Scuderia should gain a modest increase in power. The SF-26 may then be able to exploit its strength through the final high-speed corners to conserve energy for use along the circuit’s main straights.
A more powerful internal combustion engine would also improve energy recovery efficiency. Whether that will be enough remains uncertain, but with the championship fight still alive, Ferrari’s objective is clear: continue developing, continue improving and keep the battle alive for as long as possible.
