Upgrades Preview: Austrian Grand Prix

Ferrari's power unit upgrade and Red Bull's weight reduction programme headline a busy development weekend at the Red Bull Ring. Here is how every team stacks up heading into Austria.

Austria may look straightforward on paper, but the Red Bull Ring's rear-limited layout and demanding tyre characteristics make it one of the more technical venues for setup and development work. This weekend is shaping up to be one of the busiest of the season for upgrades, with both engine and aerodynamic developments arriving across the grid. Crucially, it marks the first time power unit upgrades will be fitted to cars in 2026 — and they are arriving at teams that already have considerable momentum.

McLaren

McLaren are not bringing a conventional upgrade package to Austria. Instead, the MCL40 will run an experimental upside-down rear wing — a flip-wing concept — during Friday practice only, as part of a data collection programme focused on drag reduction. The goal is to reduce drag on the straights while preserving cornering downforce and grip. Friday will serve as a direct comparison against the standard wing specification, with a race debut possible later in the season if the data is positive. It is an aggressive development programme rather than a guaranteed step forward this weekend.

Headline Upgrades: Experimental upside-down flip-wing rear wing concept. Friday evaluation only — data collection and direct comparison with standard wing. Drag reduction focus. Race debut possible later in season if data supports it.

Mercedes

Mercedes arrive in Austria without a performance-focused aerodynamic upgrade, with the team's entire development effort this weekend directed at reliability. Hybrid and battery updates arrive alongside heat management improvements and changes aimed at reducing the shutdown risk that has plagued the W17 in recent races. The goal is straightforward: ensure the car can run reliably at higher performance settings without the heat sensitivity, module failures and shutdown issues that have emerged in close racing situations. This is a reliability fix rather than a performance step, with one power unit upgrade opportunity still remaining for the team later in the season.

Headline Upgrades: Hybrid and battery updates. Heat management improvements. Reduced shutdown risk. Reliability focus — not a performance step. One PU upgrade token still remaining this season.

Red Bull

Red Bull bring what is described as their biggest package of the 2026 season and the most significant since Miami, building on incremental updates introduced across Miami, Imola and Barcelona. The headline item is a weight reduction of approximately 12 kilograms — bringing the RB22 to the minimum weight target for the first time — which alone represents a substantial performance gain at a circuit as elevation-sensitive as the Red Bull Ring. The floor has been revised with a new forward structure and updated bib geometry, while the sidepods have been reworked with a new inlet design, more aggressive drop-off, higher-walled sections and underslides for improved flow management. Front wing refinements complete the package. The targets are improved aerodynamic balance, better efficiency, reduced tyre wear and enhanced performance on elevation changes and under heavy braking.

Headline Upgrades: Approximately 12kg weight reduction — minimum weight target achieved for first time. Revised floor with new forward structure and bib geometry. Reworked sidepods with new inlet, drop-off and underslide design. Front wing refinements. Estimated major performance step.

Ferrari

Ferrari introduce the new 067/6 engine specification in Austria, paired with a new Shell fuel formulation, for a combined gain of approximately 5 to 7 horsepower — equivalent to around 5 kilowatts. This is Ferrari's first Aduo power unit upgrade of the season. Austria is identified by the team as one of the most power-sensitive circuits on the calendar, making it a logical venue for the introduction. The gain is described as noticeable rather than revolutionary on its own, but meaningful in the context of the tight margins at the front of the field.

Headline Upgrades: New 067/6 engine specification. New Shell fuel formulation. Combined 5 to 7 horsepower gain. First Aduo power unit upgrade of the season.

Williams

Williams are confirmed to be bringing circuit-specific parts to Austria. No major upgrade package is reported, with the focus on minor aerodynamic tweaks, mechanical refinements and setup optimisations as part of the team's ongoing seasonal programme.

Headline Upgrades: Circuit-specific parts confirmed. Minor aero tweaks and mechanical refinements. No major upgrade package.

Racing Bulls

No major upgrade package is confirmed for Racing Bulls this weekend. Minor detail or development updates are expected as part of the team's ongoing seasonal programme, covering small aerodynamic tweaks, mechanical refinements and setup optimisations.

Headline Upgrades: No major package confirmed. Minor aero tweaks and mechanical refinements expected.

Aston Martin

No major upgrade package is confirmed for Aston Martin this weekend. Minor detail or development updates are expected as part of the team's ongoing seasonal programme, with focus areas of reliability, tyre management and incremental aerodynamic efficiency.

Headline Upgrades: No major package confirmed. Minor refinements and setup optimisations expected.

Haas

No major upgrade package is confirmed for Haas this weekend. Minor detail or development updates are expected as part of the team's ongoing seasonal programme, with focus areas of reliability, tyre management and incremental aerodynamic efficiency.

Headline Upgrades: No major package confirmed. Minor refinements and setup optimisations expected.

Audi

Audi arrive in Austria with a meaningful power unit upgrade under the Aduo regulations, with reports pointing to a gain of approximately 10 horsepower alongside improvements to reliability and race start consistency. The aerodynamic package is understood to be decent at this circuit, with the team's straight-line speed a noted strength. Some chassis and bodywork changes may also arrive, though a more substantial aerodynamic step is expected to follow at Silverstone rather than this weekend.

Headline Upgrades: Approximately 10 horsepower power unit upgrade under Aduo regulations. Improved reliability and race start consistency. Minor chassis and bodywork changes possible. Larger aero step expected at Silverstone.

Alpine

Alpine bring a major aerodynamic update to Austria, centred on revised front and rear wings. The package builds on Pierre Gasly's recent strong performances and is targeted at pushing the A526 higher in the midfield order. The package was originally planned for Barcelona before delays pushed it back, making Austria the first proper opportunity to see it in action. Other components are not prominently reported but development continues across the car.

Headline Upgrades: Revised front wing. Revised rear wing. Package delayed from Barcelona. Goal to build on Gasly's recent form and push higher in the midfield.

Cadillac

Cadillac bring a substantial upgrade package to Austria as they continue their push to close on the midfield in their debut season. New and revised sidepods arrive alongside a revised floor and a series of other bodywork changes spanning multiple sections of the MAC26. A revised livery may also appear this weekend. The ambition is clear — accelerate progress towards the midfield battle, with Austria representing another meaningful step in a steady development programme.

Headline Upgrades: New and revised sidepods. Revised floor. Additional bodywork changes. Possible revised livery. Goal to accelerate progress towards the midfield.

Final Thought

Austria is shaping up to be one of the defining weekends of the 2026 season so far. Red Bull's combination of weight reduction and aerodynamic refinements at their home race represents the biggest single package of the weekend, while Ferrari's power unit upgrade and Mercedes' reliability fix add further intrigue at the front. The midfield picture is equally compelling, with Alpine finally delivering a long-delayed package and Cadillac continuing their steady climb. The Red Bull Ring rewards getting everything right — setup, strategy and reliability — and with so much new hardware in the paddock, the margins could be tighter than they have been all season.
