The 2026 Chinese Grand Prix weekend officially began on Thursday in Shanghai, with Formula One returning to a circuit that has long held a special place on the calendar.
The atmosphere around the paddock was noticeably different from Melbourne. While the Australian Grand Prix traditionally carries the excitement of a season opener, the Chinese fans brought their own energy — enthusiastic, patient and eager to meet the drivers.
Hundreds gathered outside the paddock entrance hoping to catch a glimpse of their favourites. Many left satisfied after securing autographs or photos as drivers arrived for media commitments.
Two drivers in particular attracted the largest crowds: Lewis Hamilton and Charles Leclerc.
Hamilton remains hugely popular in China, having won the Chinese Grand Prix multiple times during his career, including last year’s sprint race. Leclerc also drew significant attention from fans, many of whom were excited to see him arrive alongside Alexandra, who happily took selfies with supporters inside the paddock.
Hamilton himself spoke warmly about returning to China. The seven-time world champion explained that he had recently spent time in the country with his mother and hopes to explore more of China in the near future.
Yet behind the lively atmosphere, several serious topics dominated discussions after the opening race in Australia left some drivers frustrated with the new generation of Formula One cars, while several teams encountered reliability challenges.
Aston Martin and Honda Continue Work on Vibration Issue
On the technical side, Thursday’s media programme began with an update from Aston Martin team representative Mike Krack, who appeared alongside Honda engineer Shintaro Orihara.
The message remained largely consistent with the team’s comments following the Australian Grand Prix.
Both Aston Martin and Honda confirmed that engineers are continuing to work intensively on the vibration issue affecting the interaction between the power unit and battery systems.
According to the team, progress has been made in reducing battery vibrations during dyno testing at the factory. Engineers have identified a potential countermeasure, although the issue has not yet been fully resolved.
Krack stressed that reliability remains the immediate priority.
Without a stable car, he explained, the team cannot complete the mileage required to properly understand the full performance potential of the package.
The team declined to reveal how many usable batteries they have available this weekend. However, Aston Martin confirmed that engineers are attempting to repair previously damaged battery units to increase their supply.
Both Aston Martin and Honda also clarified that the battery failures themselves are not directly caused by the vibration issue but instead involve smaller internal component failures.
Drivers Voice Concerns Over New 2026 Regulations
Following the technical update, the day moved into the usual series of driver media sessions and the official FIA press conferences.
Much of the discussion focused on the early impact of the new 2026 Formula One technical regulations.
Several drivers openly criticised the current racing dynamics, describing overtaking as somewhat artificial because of the heavy emphasis on energy management systems.
Others warned that the complexity of the new power units — particularly battery deployment and energy harvesting — is making race starts increasingly unpredictable.
Pérez Raises Safety Concerns Over Race Starts
One of the most direct safety warnings came from Cadillac driver Sergio Pérez.
The Mexican driver raised concerns about race starts under the new regulations, explaining that the interaction between battery deployment, regeneration systems and energy management makes the launch phase far more complicated.
“Starting with these new power units is very difficult,” Pérez said.
He pointed to incidents seen in Melbourne, including Liam Lawson’s stalled start, as examples of how easily problems can arise.
Managing anti-stall systems while simultaneously balancing energy recovery and deployment adds another layer of complexity, increasing the risk of irregular launches.
Pérez admitted that there are no easy regulatory fixes, as any changes would require agreement from all teams.
More broadly, he also criticised the racing dynamics of the new cars, describing parts of the racing as “somewhat artificial” because of the heavy reliance on energy management.
Looking at the bigger picture, Pérez described the Australian Grand Prix as an important milestone for his team. Simply finishing the race marked the end of Cadillac’s early “honeymoon phase”, with the focus now shifting toward gradually reducing the performance gap to established teams.
Russell Confident Mercedes Can Adapt
Meanwhile, George Russell expressed confidence that Mercedes has already improved its procedures after analysing the opening round in Melbourne.
Russell explained that part of the difficulty at race starts comes from the FIA’s current formation-lap energy harvesting limit, which can disadvantage drivers starting near the front of the grid by restricting how much battery energy they can regenerate before the race begins.
Despite the complication, Russell expects teams to adapt quickly as they gain more experience with the new systems.
Looking ahead to Shanghai, he suggested the circuit should produce a more conventional energy pattern than Melbourne.
With its long main straight, most drivers will deploy the majority of their battery energy in one location, reducing some of the unusual power-management behaviour seen in Australia.
Russell also played down suggestions that Mercedes currently holds a clear advantage.
According to the British driver, several teams now operate comparable power units, meaning overall car design — rather than engine power alone — is increasingly determining performance differences.
Ferrari Expect Different Challenge in Shanghai
Ferrari approached the Chinese Grand Prix weekend with cautious optimism.
Both Charles Leclerc and Lewis Hamilton emphasised that the Shanghai circuit differs significantly from Melbourne and could better suit the characteristics of the Ferrari car.
The Maranello-based team is expected to run its distinctive “Macarena” rear wing configuration, an aerodynamic concept designed to improve efficiency on long straights.
The design offers advantages in aerodynamic efficiency but carries a small weight penalty.
Despite their optimism, the Ferrari drivers also warned that Mercedes should not be underestimated.
Both suggested that the Brackley team may not yet have shown the full potential of its package.
Haas Encouraged but Cautious Ahead of Sprint Weekend
The final notable media appearance of the day came from Haas team principal Ayao Komatsu.
Komatsu described the Australian Grand Prix as a positive start to the season for Haas despite operational challenges earlier in the weekend.
After a difficult Friday in Melbourne, the team recovered through improved execution in FP3, qualifying and the race.
By focusing on what Komatsu called “the basics” — strategy, pit stops and race management — Haas ultimately secured a points finish.
However, he warned that the Chinese Grand Prix will present a very different challenge.
With the sprint format allowing only one practice session, teams will have extremely limited time to understand and optimise their cars before competitive sessions begin.
Komatsu also highlighted the growing intensity of the midfield battle.
Haas is closely monitoring several direct rivals — particularly Audi and Racing Bulls, as well as Mercedes-powered teams Alpine and Williams.
His comments on Audi were particularly notable. The newcomer has already shown strong straight-line performance, and Komatsu suggested the team could quickly establish itself as a serious midfield contender as the season develops.
