Toto Wolff emphasized the importance of understanding recent upgrades for Mercedes' 2027 car development after a promising performance at the Singapore Grand Prix. The team took an unusual approach by running two different car specifications due to issues with their major upgrade introduced at the previous race in Malaysia.

• Kimi Antonelli drove the newer specification, while George Russell used the older package, starting from the back of the grid due to engine penalties.
• Russell initially outperformed Antonelli in the Sprint sessions, but Antonelli later secured third place in the main race, getting closer to clinching the world title.

Antonelli expressed optimism, stating, "we started to see the light at the end of the tunnel." Wolff reflected on the split strategy, noting that it was essential to enhance their learning curve despite the challenges.

He remarked, "This new car needs a very different set-up philosophy than the previous car. Was it an easy car like the previous one? I don't think it was. Does it have the performance that we were hoping the upgrade would bring? I don't think so yet. But it was a step in the right direction."

Looking ahead to the United States Grand Prix, Wolff indicated that both cars would likely run the newer specification, pending a final team decision. He added, "Both drivers think it should have a positive effect, or it should have a benefit, in Austin. This is the right direction to go for our learning for next year."
