Ferrari’s edge in the 2026 Formula 1 title fight has increasingly come from reliability, with Lewis Hamilton saying the team’s consistency has become one of its biggest advantages as Mercedes continues to battle engine and battery problems that could yet lead to grid penalties. Hamilton said Ferrari’s processes, pit stops and factory preparation had helped it stay more dependable than Mercedes, though he stressed that no penalty outcome had been confirmed for his team. Current component usage shows the teams are tied on key power unit parts, with Ferrari having used more MGU-K units and Mercedes more exhaust components.

That reliability gap showed again at Silverstone, where Charles Leclerc led Ferrari to victory in the British Grand Prix after the team’s upgraded power unit, introduced in Austria, appeared to improve its competitiveness at a circuit that was expected to suit Ferrari less. Kimi Antonelli had taken pole for Mercedes and was in contention before a broken wheel shield and a track-limits penalty dropped him to 15th. George Russell finished on the podium, helped by the Safety Car and Max Verstappen’s crash, while Ferrari scored 40 points. Ferrari also showed a straight-line speed weakness during the weekend, which Russell and Antonelli both noticed.

Mercedes boss Toto Wolff said the team needed to look at itself after the race and warned Ferrari could remain a serious threat for the rest of the season. Former Formula 1 driver Anthony Davidson said Mercedes’ reliability problems had opened the door for Ferrari to fight for the championship, describing Ferrari’s machinery as bulletproof. Mercedes trackside engineering director Andrew Shovlin said the team was adding performance in smaller steps rather than relying on one major upgrade package, and Hamilton said Mercedes must keep maximizing points and limit damage in races it cannot win as the reliability problems continue to hang over the title battle.

Audi Formula 1 boss Mattia Binotto has urged the FIA to rethink the sport’s Additional Development and Upgrade Opportunities, or ADUO, scheme, warning that its current performance-based rules could be exploited by manufacturers that are already competitive. Binotto said the system relies too heavily on V6 or internal combustion engine performance, even though ADUO upgrades can apply to the full power unit, including hybrid components. He argued that a team with a stronger chassis or overall car could avoid showing the true potential of its engine and still gain extra development time, which runs counter to the scheme’s aim of helping manufacturers that are genuinely behind.

The concern has sharpened after Mercedes received an additional development allowance under the rules, even though its engine has been widely regarded as the strongest on the grid and the team has won seven of the first nine grands prix in 2026. Red Bull Ford Powertrains was treated as the benchmark and was denied extra upgrades beyond the standard homologation timetable, a ruling Red Bull challenged unsuccessfully. Rival manufacturers have also suspected that some teams may be withholding V6 performance to gain an advantage within the ADUO system.

Binotto said the FIA has done important work on the concept but needs to adjust the rules so they better support long-term convergence across the full regulatory cycle. The FIA said the teams agreed to the current process, which uses ICE-based evaluation windows to allocate development opportunities. Under the latest assessment, Mercedes received one upgrade, while Ferrari, Audi and Honda each received two for being about 4% behind Red Bull Ford.

Lewis Hamilton said Mercedes could face grid penalties later this season because of repeated battery-related reliability failures in its F1 power-unit components. Under F1 rules, each driver is limited to three Energy Store units and three MGU-K units for the season, and any extra component brings an immediate 10-place grid penalty. Hamilton, who trailed Kimi Antonelli by 32 points in the standings, said Mercedes had not matched Ferrari’s reliability this year and should keep maximizing points in races it cannot win while limiting the damage when problems arise.

Mercedes’ reliability issues have already affected both George Russell and Kimi Antonelli. Russell retired from the Canadian Grand Prix while leading because of a battery problem, and Antonelli retired in the closing laps in Barcelona with a similar issue. Hamilton said those failures made later grid penalties a real possibility and described Mercedes’ current reliability troubles as unusual for the team.

The concerns came after another difficult British Grand Prix weekend at Silverstone, where Ferrari beat Mercedes for the second time this season. Charles Leclerc won the race, Russell finished second, and Hamilton finished third. Russell also said he was losing power on the straights, underscoring Mercedes’ problems with straight-line speed and energy deployment, while team boss Toto Wolff rejected that explanation as the main reason for Russell’s recent struggles.

Fernando Alonso used the British Grand Prix weekend at Silverstone to question Formula 1’s direction, saying the sport’s 2026 regulations are moving overtaking away from driver skill and toward battery deployment. Alonso said modern passes can now be made by pressing a button when more energy is available, rather than through braking, positioning and risk-taking, and argued that a better power unit can decide whether an overtake happens at all. He went as far as saying drivers need “no talent” for some of the battery-assisted moves seen under the current rules.

He pointed to the Silverstone sprint race as evidence, citing Kimi Antonelli’s pass on Lewis Hamilton and Hamilton’s duel with George Russell in Sunday’s race. Alonso said the sprint showed cars could pass in the middle of straights by using extra battery power, a pattern he believes reduces the competitive value of the new regulations. The comments fit into broader criticism of the newer rules that has built since the start of the season, and Damon Hill backed Alonso’s concern, warning Formula 1 must decide what kind of sport it wants to be as technology becomes more influential.

Alonso’s frustration also came from a difficult weekend for Aston Martin, after his car shut off during the formation lap. He started from the pit lane and finished 18th, outside the points, though he said the race still provided useful data for the team. Looking ahead to the Belgian Grand Prix at Spa, Alonso expects energy management to shape the race again, and suggested the high-speed corners and long straights could produce a similar pattern.

F1 is preparing to expand its Sprint schedule in 2027, with CEO Stefano Domenicali saying the sport wants to give fans more action across the full weekend. Speaking during the British GP weekend at Silverstone, he said the Sprint format has boosted interest in F1 and that the next calendar is expected to be announced soon. Reports have suggested the number of Sprint weekends could rise to nine or 10 in 2027, up from six, although Domenicali did not confirm a final figure.

Domenicali pointed to Silverstone’s strong turnout, including 150,000 fans on Friday, as evidence that Sprint weekends can attract crowds beyond race day. He said F1 has a responsibility to be bold and think out of the box, and described the Sprint concept as a successful part of the sport’s event strategy. First introduced at the 2021 British GP, the format adds Friday qualifying, a Saturday Sprint race and a shorter build-up to Sunday’s Grand Prix.

Wider calendar changes are also being considered for 2027. One report said the season could grow to 34 races if Sprint weekends rise to as many as 10 while the Grand Prix total stays at 24. The reports also said Zandvoort is expected to drop off the schedule, while Portugal and Turkey are already confirmed to return. Barcelona is expected to alternate with Belgium before coming back in 2028, with Bahrain and Saudi Arabia also set to return.
