Wolff and Mercedes have their 'little secrets' about their plans to develop its 2026 car

Of course, Formula 1 takes a huge leap into the unknown next year, with the 2026 regulations shaking up the pinnacle of motorsport hugely. A return of active aerodynamics, plus a 300% increase in electrical power in power units, are just two of the many changes that teams will have to deal with.

The key question for many teams will be whether they should stop developing their 2025 car already and focus on the major changes for next season.

For Mercedes, an interesting decision will have to be made. The German team currently sit P2 in the constructors' championships, with updates that are coming to the Emilia Romagna Grand Prix, hopefully closing the gap at the top to McLaren. But a lack of development into their 2026 car means they could start the next campaign on the back foot.

In Miami, the Mercedes team principal was asked where the focus on development lies with that quandary in mind. But the Austrian team boss was not giving anything away.

"I think every team will have their little secrets," said a cryptic Wolff in Friday's constructors' press conference at the Miami Grand Prix.

"You’re adding lots of downforce in because it's the early days, and that's going to flatten. But if a team has started doing it one and a half months earlier in terms of transitioning resources, that can be a big advantage next year," the Austrian concluded.
