Pirelli has confirmed tire compound allocations for the upcoming five-day pre-season shakedown at the Circuit de Barcelona-Catalunya. Teams may run on only three of the five days. Available rubber includes three slick compounds, including C1 (hard), C2 (medium), and C3 (soft), plus intermediates and full wets. Pirelli described the week as a tire-focused preparation rather than a full aerodynamic programme.

Cadillac will make its first on-track outing in a championship environment during the Barcelona shakedown. Williams withdrew after significant FW48 assembly delays, leaving one team absent from the private running.

Team allocations reveal contrasting test priorities. Red Bull took 18 sets of C3 softs, only one set of C2 mediums, and no C1 hards, signalling a short-run, peak-performance focus. Mercedes brought a paddock-high eight sets of C1 hards, requested 12 C3s (per reports), and skipped C2s, indicating emphasis on long runs with some short-run work. Ferrari prioritized medium-run data with 12 C2s and just three C3s. Both Ferrari and McLaren will skip the shakedown’s opening day. Other notes from the build-up to the Shakedown include Williams reportedly ordering 17 C3s before withdrawing, Haas requesting the most intermediates (six), and Audi securing the most wets (three). An unnamed reference to the reigning world champions recorded a balanced split of four hards, ten mediums, and six softs.

With teams limited to three running days, these inventory choices will tightly shape the data each squad can gather in Barcelona and help set the early direction of their 2026 programmes: heavy soft allocations point to qualifying-style exploration, while larger hard inventories indicate priorities around extended running and race simulation.

Haas completed the maiden laps of the VF-26 at Ferrari’s Fiorano test circuit, with junior Oliver Bearman driving and teammate Esteban Ocon observing. The run produced the first on-track images after the car’s online launch earlier this week, including a photo captioned ‘The VF-26 is alive’ showing Bearman leaving a Shell-branded garage on Pirelli intermediate (demonstration) tyres. The VF-26 carried prominent Toyota Gazoo Racing branding during the outing.

Haas described the activity as a shakedown to collect vital data and perform systems checks ahead of the official Barcelona pre-season test, scheduled for January 26–30. The team did not clarify whether the Fiorano running fell under a filming-day allowance (which permits up to 200 km) or a shorter demonstration run (up to 15 km), leaving some procedural details unspecified.

Team principal Ayao Komatsu said Haas will bring a different specification to Barcelona than the car it plans to race in Australia. He stressed that the team is on an aggressive development program to adapt to 2026 technical priorities, including the roughly 50:50 split between internal combustion and hybrid power. Komatsu reaffirmed that Haas’s foundational technical relationship with Ferrari, including the use of Ferrari power units, remains intact despite the new title partnership and strengthened technical alliance with Toyota. The principal emphasized there will be no crossover between the two teams’ technical programmes. Haas positioned the Fiorano outing as an important early step in preparing the VF-26 and the team’s programme for the new era of Formula 1.

This week, Audi launched a development program to identify and nurture drivers from karting through the single‑seater ladder, offering a pathway to F1. The initiative was announced alongside the unveiling of Audi’s F1 car, the R26, and forms part of a five‑year plan, following the entity’s acquisition of Sauber. Audi outlined their road map for the future, revealing its ambition to win a world championship by 2030.

Former F1 driver and three‑time Le Mans winner Allan McNish will lead the programme, bringing experience from sports car racing and senior management roles within Audi.

Audi said the program will give prospects access to the company’s technical resources, engineers, and specialists, along with training in engineering, human performance, media, and marketing. The aim is to embed young drivers in Audi’s technical and operational culture and to prioritise resilience, intelligence, and a team‑driven mindset with raw speed.

Team principal Jonathan Wheatley described the initiative as a key pillar of Audi’s long‑term F1 strategy and part of its vision toward 2030.

The move places Audi alongside other works-run talent systems, such as Red Bull, Alpine, and McLaren, programs that have produced champions including Sebastian Vettel, Max Verstappen, and Fernando Alonso. Audi acknowledged that building and maintaining such a pipeline requires significant investment and carries risk, but framed the program as evidence of a continued commitment to building a competitive, sustainable F1 team.

Alpine staged its 2026 season launch on an MSC Cruises ship off the Catalan coast near Barcelona, unveiling a glossy showcar that retained the team’s trademark blue with prominent BWT pink branding. The display car was presented as an illustration of the team’s look under the new regulations rather than the final A526 race car, giving fans a clear view of the blue-and-pink sidepod graphics and sponsor placement at the event.

Earlier in the week, Alpine completed a limited shakedown of the Mercedes-powered A526 at Silverstone, where Pierre Gasly covered roughly 140 km of the 200 km permitted on a wet, dark day. Initial images from that run showed noticeable differences in engine and sidepod packaging when compared with the Mercedes factory car, a visible consequence of Alpine’s shift from works status to a Mercedes customer supply arrangement under the 2026 engine rules.

Executive technical director David Sanchez said the A526 faces fresh challenges from new features such as active aero and increased electric power as a result of Alpine’s technical partnership with Mercedes-AMG. The Enstone team substantially scaled back work on the 2025 car to concentrate resources on the new regulations, a strategy that left Alpine with a disappointing 10th-place finish in the 2025 constructors’ championship with 22 points. Pierre Gasly has committed his long-term future to the team and will race alongside rookie Franco Colapinto in Colapinto’s first full Formula 1 campaign. Alpine plans to take the A526 to the opening pre-season test at the Circuit de Barcelona-Catalunya on January 26–30 to finalize preparations for the 2026 season.

Ferrari unveiled the SF-26 at its Fiorano base in a 10:30 GMT livestream, releasing digital images ahead of the rollout. Drivers Charles Leclerc and Lewis Hamilton attended, and the car undertook initial laps at Fiorano later that day, ahead of Barcelona pre-season testing scheduled to begin in three days. The timing was intended to give Ferrari early on-track data ahead of the formal test program after the team paused SF-25 development to concentrate resources on a clean-sheet 2026 challenger.

The 2026 regulations bring a new power-unit architecture and a revised aerodynamic philosophy, which Ferrari described as a rare opportunity to end an almost 20-year constructors’ title drought and return to drivers’ title contention. Team leaders pointed to the move to an in-house power unit and a reorganized technical leadership under Loïc Serra as potential long-term advantages, while stressing that eliminating past operational lapses will be critical to turning potential into results. Leaks and reporting around the launch suggested a return to pushrod suspension at both ends (including possible double-pushrod geometry) and experimentation with steel cylinder heads for the new power unit; those technical details remained unconfirmed at the official presentation.

Against a backdrop of a disappointing 2025 season, Ferrari finished fourth in the constructors’ standings with no wins. The launch combined a new livery, an on-track shakedown, and an operational message of renewed focus. Charles Leclerc, signed through at least 2026, outperformed his team-mate in 2025, while Lewis Hamilton recorded his first season without a podium after moving from Mercedes, leaving both drivers under pressure to deliver. The Fiorano shakedown and upcoming Barcelona tests will be the first practical measures of whether Ferrari’s technical and organizational changes translate into a genuine step forward on track.

Racing Bulls, the Faenza-based VCARB F1 squad, appointed Dan Fallows as technical director, and he will join the team in April. He will oversee the team’s design, aerodynamics, and performance programmes and will report to chief technical officer Tim Goss. The post had been vacant since Jody Egginton moved to Red Bull Advanced Technologies, and Racing Bulls said the hire is part of a push to accelerate its development ahead of the 2026 season. The team’s new car, the VCARB 03, completed its first run at Imola earlier that week.

Fallows returns to the Red Bull group after a long F1 career. He worked at Jaguar from 2001 to 2004 and at Red Bull from 2006 until 2021, and he was recruited to Aston Martin as technical director in 2022. He was dismissed after a disappointing 2024 campaign and left Aston Martin’s F1 operation at the end of 2024. After a spell at Aston Martin Performance Technologies, he founded Hiperformant in June 2025 to apply F1 expertise to high‑performance engineering and business development; reports said his Racing Bulls appointment comes about ten months after he moved on from Aston Martin Performance Technologies.

Team principal Alan Permane called Fallows’s technical understanding and leadership “a real asset,” while the man himself said he was “very pleased to be joining VCARB at an exciting time for the team.” However, he cautioned that it will be some time before a design he directly influences reaches the track. Fallows will assume full responsibilities in April after completing his gardening leave.

Ferrari confirmed recently that Riccardo Adami has moved into a new role and that it has not yet named a permanent replacement for Lewis Hamilton’s race engineer. Charles Leclerc’s race engineer, Bryan Bozzi, will split duties and work with both drivers during the Barcelona pre-season shakedown while staffing is finalized. Reports say there is “no chance” of signing Peter Bonnington, Hamilton’s long-time race engineer at Mercedes, as a replacement.

Former driver and commentator Martin Brundle said he was surprised the change had not been made earlier and warned the timing is risky given upcoming pre-season running. Brundle emphasized that Hamilton benefits from engineers who understand his “Lewis speak” to interpret feedback and extract performance. The pundit cited several terse radio exchanges between Hamilton and Adami during 2025 as evidence that communication and rapport needed addressing.

Ferrari framed the engineering change as part of preparations for the new 2026 technical regulations and to improve in-race communication. The team has scheduled the SF-26 launch and planned two three-day tests in Bahrain in February as it prepares for the regulation change. The Barcelona shakedown, the lack of a named permanent race engineer, and the temporary split of Bozzi’s duties will be watched closely for signs of Hamilton’s readiness with the new car.

The 2026 season begins at Albert Park and will include a new Madrid event in September, before concluding in Abu Dhabi.

Rival manufacturers raised alarms about a perceived loophole in the new 16:1 compression-ratio limit after reports suggested Mercedes and, to a lesser extent, Red Bull, had found a way to pass ambient, stationary FIA checks while running an effectively higher compression on track. Industry estimates put the potential benefit at roughly 10–15 bhp (commonly expressed as about 0.3–0.4 seconds per lap), and observers warned that customer teams using Mercedes power units, namely McLaren, Williams, and Alpine, could also gain.

Ferrari, Audi, and Honda formally pressed the FIA for clarity. Audi’s F1 project chief Mattia Binotto urged a measurement method that captures operating (hot) conditions and warned against filing protests without clear evidence. Audi technical director James Key called for decisive action to preserve the rules’ intent. Red Bull Powertrains (RBPT) technical director Ben Hodgkinson described its unit’s compliance as “crystal clear” and downplayed the controversy. The dispute focused on whether rule C5.4.3, which defines compression under ambient conditions, could be exploited through thermal expansion during the engine’s working cycle.

Teams discussed responses ranging from formal protests to attempts to replicate the approach under the 2026 in-season development framework. The FIA convened engine technical experts and manufacturer representatives earlier this week to resolve the interpretation.

Attendees agreed on a technical route to measure compression ratios at operating (hot) temperatures, creating a clear path to close the perceived loophole. However, ambient-temperature measurements remain the official standard for now; any formal change to testing or enforcement will require consultation with manufacturer principals and a vote in the F1 Commission. That Commission includes several Mercedes-powered teams and two Red Bull squads, so immediate implementation for the 2026 season was not expected.

The meeting established a future measurement methodology and clarified enforcement intentions, but the timing and adoption of a hot-temperature testing regime for 2026 remain uncertain. Teams will watch the consultation and Commission process closely for any binding change.

Mercedes completed the first shakedown of the W17 at Silverstone on Thursday, hours after unveiling the car in render form. Using one of its two permitted filming days, the team ran the full chassis-and-engine package for 67 laps, just under the 200 km promotional-day limit, in wet, cold conditions on the Silverstone International Circuit. George Russell and rookie Kimi Antonelli split driving duties; Mercedes ran on Pirelli’s grooved demo tyres and released footage that included shots of team principal Toto Wolff.

Head of trackside engineering Andrew Shovlin described the outing as a sensible first step focused on safety, reliability, and driver familiarisation. The team prioritized basic systems checks and baseline data over performance runs.

The session followed Alpine’s engine-only fire-up of Mercedes’ V6 hybrid at Silverstone the previous day and was Mercedes’ first on-track check of the complete car-and-engine combination. Mercedes said it will head to Barcelona to extend running and further acquaint both drivers with the W17 ahead of the pre-season test from January 26–30. The FIA granted extra testing scope this winter because chassis and engine rules are changing together for the first time since 2014, and nearly half of the 11-team grid had already completed early shakedowns. Mercedes positioned the Silverstone outing as a cautious, low-speed validation of hardware and software integration, a productive step ahead of broader pre-season running.
