F1TECH: How many upgrades have teams brought so far across the opening stages of the season? F1Technical’s senior writer Balazs Szabo analyses how the 11 teams have approached development during the opening stages of the 2026 Formula 1 season, revealing significant differences in both the volume and focus of their upgrade programmes. With the first eleven Grands Prix of the season completed, the teams have already introduced 323 upgrades across five major areas: the front wing, rear wing, suspension, floor and bodywork. The figures show that development has been particularly intensive among the leading teams, although the numbers also reveal some fascinating differences in philosophy between the constructors. Red Bull leads the upgrade countRed Bull has introduced the most upgrades so far, with 38 modifications, putting the Milton Keynes-based team at the top of the development standings. Ferrari and McLaren follow with 35 upgrades each, while Cadillac has remarkably accumulated 34, just one fewer than the two established front-running teams. Racing Bulls and Aston Martin have both introduced 30 upgrades, followed by Haas with 28, Audi with 25, Williams with 24, Mercedes with 23 and Alpine with 21. The numbers underline an interesting contrast. Three of the four established leading teams – Red Bull, Ferrari and McLaren – are among the four most active teams, while championship-leading Mercedes has brought considerably fewer upgrades. Mercedes team principal Toto Wolff has already indicated that the Brackley-based outfit could increase its development effort during the second half of the campaign. Aston Martin leads the front-wing developmentThe front wing has been an important development area despite the radically different aerodynamic philosophy introduced by the 2026 regulations. Aston Martin leads the field with seven front-wing modifications, followed by Ferrari and Red Bull with six each. Haas, Cadillac, Audi and Alpine have each introduced five modifications, while Mercedes has four. McLaren has brought three, with Racing Bulls and Williams at two apiece. It is important to clarify that these figures do not necessarily represent completely new front wings. A single wing assembly consists of numerous components - three flaps, the endplates and the additional vanes-, and the statistics count individual upgraded elements. Haas and McLaren focus heavily on rear wingsThe rear wing has been another major development battleground. Haas leads the field with 10 rear-wing modifications, ahead of McLaren with nine. Ferrari, Racing Bulls and Alpine have each introduced eight, while Mercedes, Red Bull and Williams have seven apiece. Cadillac has brought six rear-wing modifications, Audi five and Aston Martin four. The figures demonstrate how teams have been searching for aerodynamic efficiency under the new 2026 rules, with the rear wing remaining a critical area for balancing downforce and straight-line performance with the introduction of the straight-line and cornering modes. McLaren leads suspension developmentMcLaren has been particularly aggressive in developing the suspension and associated brake-corner aerodynamic components, recording 11 modifications in this category. Red Bull follows with nine, while Racing Bulls has introduced eight. Mercedes, Ferrari, Audi and Williams have each brought six suspension upgrades. Haas has five, while Cadillac, Aston Martin and Alpine have four apiece. The suspension category includes brake ducts and associated components, which are important not only for brake cooling but also for their aerodynamic influence around the front and rear corners of the car. Ferrari has found huge potential in the floorOne of the most striking figures in the entire analysis concerns Ferrari's floor development. The Maranello-based team has introduced 12 floor modifications, the highest total of any team and one of the main reasons Ferrari has reached 35 upgrades overall. McLaren follows with 11, while Cadillac has 10. Red Bull and Racing Bulls have each introduced six floor modifications, with Haas and Aston Martin on five and Audi and Williams on four. Mercedes, meanwhile, has modified its floor just three times, while Alpine has introduced only two changes in this area. Although floors are not as dominant as they were during the previous ground-effect era between 2022 and 2025, when Venturi tunnels were fundamental to generating downforce, the 2026 regulations still provide opportunities to find performance through the diffuser, floor body and other aerodynamic elements. Cadillac's remarkable development programmePerhaps the biggest surprise in the table is Cadillac. The new American entrant has already introduced 34 upgrades, putting it fourth overall and only one modification behind Ferrari and McLaren. Cadillac has been particularly aggressive with its floor and bodywork development, introducing 10 floor modifications and nine bodywork upgrades. The team has also introduced five front-wing and six rear-wing modifications, along with four suspension upgrades. Cadillac's development programme has included two particularly comprehensive packages in Miami and Austria. The team has generally brought around two upgrades to most Grands Prix, with the exception of the British Grand Prix, where it introduced no new components after its major Spielberg package. For a new team entering Formula 1 under an entirely new technical regulations cycle, Cadillac's development rate is particularly notable. Mercedes has taken a different approachMercedes has introduced just 23 upgrades, the lowest total among the four leading teams and the second-lowest figure overall ahead of Alpine. The Silver Arrows brought no upgrades in China, Japan or Great Britain. Their biggest package arrived in Canada, where they introduced eight modifications, while most of the remaining events saw only two or three new elements. This relatively conservative approach has not prevented Mercedes from leading the championship, but it could become increasingly significant as the season progresses. Toto Wolff has suggested that Mercedes could step up its development programme during the second half of the year, potentially meaning that the balance between development quantity and performance gains will become one of the major stories of the championship. Ferrari and Red Bull followed similar development strategiesFerrari's 35 upgrades have been distributed relatively evenly across most areas, although its 12 floor modifications stand out. The Scuderia did not submit any upgrades in Canada or Belgium but introduced two major comprehensive packages in Barcelona and Miami. Red Bull, meanwhile, has pursued a development strategy partly similar to Ferrari's. The Milton Keynes-based team introduced two particularly large packages in Miami and Austria, contributing to its leading total of 38 upgrades. China was the only Grand Prix at which Red Bull did not submit an upgrade. The RB22's development programme has therefore been characterised by periods of relatively limited activity followed by large, concentrated packages. McLaren's development came in major bursts McLaren has also accumulated 35 upgrades, but its development pattern has been distinctive. The reigning front-running team did not introduce upgrades in China or Japan before launching a sequence of major packages. McLaren brought comprehensive developments in Miami, Canada and Monaco, with each package containing approximately six or seven upgrades. Its overall figures are particularly impressive in the rear-wing and suspension categories, with nine and 11 modifications respectively. Haas has struggled to maintain its early momentumHaas began the season aggressively, introducing seven upgrades at the season-opening Australian Grand Prix. However, the American team subsequently settled into a pattern of bringing one or two upgrades to most races, and its competitiveness gradually declined after its strong start. Haas later introduced a substantial five-component package in Montreal. Nevertheless, the development did not produce the clear performance step forward the team had hoped for. The team has nevertheless recorded 28 upgrades, including a field-leading 10 rear-wing modifications. Aston Martin's unusual development programmeAston Martin's development story is perhaps the most unusual of all 11 teams. The Silverstone-based outfit introduced eight upgrades in Melbourne, but subsequently almost completely stopped bringing new components. There were seven races in which Aston Martin submitted no upgrades, a development pattern very different from that of its rivals. The decision was deliberate. Managing Technical Partner and Team Principal Adrian Newey explained that the technical group identified fundamental issues and correlation problems during winter testing and chose to concentrate its efforts rather than continue developing a car whose underlying concept required attention. The result was a dramatic return to the development race at the Hungarian Grand Prix, where Aston Martin introduced a B-specification car featuring 16 upgraded components. That package instantly transformed Aston Martin's position in the overall development statistics, taking the team to 30 upgrades despite its lengthy period of inactivity. Williams continues to search for a breakthroughWilliams has endured a difficult campaign, with Carlos Sainz and Alex Albon frequently struggling to progress beyond Q1. The Grove-based team introduced a seven-element package in Miami, followed by another substantial series of upgrades at the Belgian and Hungarian Grands Prix. However, Williams has not sounded completely confident about the effectiveness of all the new components, highlighting an important distinction between simply introducing upgrades and successfully extracting performance from them. The team's 24 modifications rank it ninth in the overall development standings. Audi develops consistentlyAudi has taken a more consistent approach than several of its rivals. The German manufacturer has brought upgrades on a regular basis, with its largest package arriving in Austria and containing seven upgraded components. There have been only three races – Japan, Barcelona and Silverstone – where Audi did not submit any upgrades. With 25 modifications, Audi sits just behind Haas and ahead of Williams and Mercedes in terms of total development activity. Alpine continues an inconsistent development path Alpine has introduced the fewest upgrades of any team, with 21 modifications. Its development programme has been characterised by two major packages, arriving in Miami and Austria, rather than a constant stream of smaller updates. The Enstone-based team has introduced five front-wing and eight rear-wing modifications, but only two floor and two bodywork upgrades. Quantity does not automatically mean performanceThe figures provide a insight into how the teams are approaching the first season of the new regulations, but the raw number of upgrades should not be interpreted as a direct ranking of development performance. A team can introduce several small modifications to a single aerodynamic assembly, while another may introduce a completely new concept that is counted as only one upgrade. The timing of the upgrades is also crucial. A large package introduced early in the season gives a team more opportunities to exploit the performance gain, while a major package arriving later can alter the competitive picture in a short period of time. This is particularly evident in the cases of Aston Martin and Cadillac. Aston Martin's 30 upgrades include the enormous 16-component B-specification package introduced in Hungary, while Cadillac has steadily accumulated 34 modifications throughout the opening races. The development race is only beginningThe first 11 Grands Prix have already produced more than 300 recorded upgrades, but with the season continuing into its second half, the development battle is far from over. Red Bull currently leads the upgrade count with 38, followed by Ferrari and McLaren on 35. Cadillac's remarkable 34 puts the newcomer immediately behind the established front-running teams. Mercedes, meanwhile, has achieved the strongest championship results despite having introduced only 23 upgrades. That contrast could become increasingly important as the season progresses. If Mercedes now increases its development rate, while Red Bull, Ferrari and McLaren continue their aggressive programmes, the second half of the 2026 season could produce an even more intense technical arms race.
