Formula One 2026: Key questions answered ahead of a groundbreaking season

By Alyssa Clang | Last updated Mar 4, 2026 2:19 PM ET

A new era of Formula One will begin March 7 in Melbourne, and the grid may never look the same.

With sweeping 2026 technical regulations wiping the slate clean for everyone from reigning champions McLaren to newcomer Cadillac, the Australian Grand Prix won’t just start a season — it will launch a reset.

But what are those regulations? How will they affect this season's racing? And which teams will understand them best?

What are these new F1 technical regulations?

The new regulations are, well, technical, but they fit into two main categories: aerodynamics and power units.

From an aerodynamic perspective, the 2026 F1 vehicles will be much smaller and lighter than their previous counterparts. Each vehicle will also deploy a new wing feature called Active Aero that changes front- and rear-wing angles and eliminates the need for traditional drag reduction systems. From a racing perspective, this means that the days of heavy, low-riding builds are over. The 2026 cars should be much zippier and more responsive.

From a power-unit perspective, the 2026 vehicles will shift to a roughly even split between gas and electric power. This requires a net-new power unit build for every manufacturer and opens up fascinating possibilities for battery recharging and strategic energy deployment. Drivers will use saved battery power to engage "Overtake Mode" and generate extra speed when they're within one second of the car ahead of them.

In theory, these new regulations should level the technical playing field and put a bigger spotlight on drivers' skills. With more flexibility through corners, less downforce and driver-powered wing and battery elements, these 2026 vehicles are incredibly complicated to drive.

For a deeper dive into these new regulations, check out F1's breakdown here.

How often does F1 make sweeping technical changes like this?

Pretty often. Technical changes occur every year as drivers, manufacturers and regulators learn more about the cars, but revolutionary switches like this only happen every four or five years.

Are there any other big changes coming to F1 in 2026?

Yes — and it's a doozy. For the first time in ages, a net-new team is entering the fray.

Cadillac, the American manufacturer, will make its F1 debut this season as the 11th team on the grid. That means we'll have 22 drivers instead of 20 competing in each race this season.

While Cadillac is new, its drivers are old friends. The team picked up the services of two veterans: Finnish driver Valtteri Bottas, who made his name as Lewis Hamilton's partner at Mercedes, and Mexican driver Sergio "Checo" Perez, who made his as Max Verstappen's partner at Red Bull.

Which teams (and drivers) look set to challenge for an F1 title in 2026?

All eyes are on Ferrari. The Italian team looked fabulous in preseason testing and could finally be a real player in the F1 championship. It hasn't won a drivers championship since Kimi Raikkonen took home the title in 2007. With Lewis Hamilton and Charles Leclerc behind the wheel, that could all change in 2026.

But while Ferrari looks to be the strongest team, Mercedes looks to have cracked the power unit better than anyone else. That means that every team featuring a Mercedes unit — Mercedes itself, McLaren, Alpine and Williams — could have an advantage over its competitors. On the driver side, that's excellent news for defending champion Lando Norris of McLaren, his teammate Oscar Piastri and Mercedes lead driver George Russell.

Are any F1 teams, drivers in trouble?

Yup. Aston Martin, featuring drivers Lance Stroll and Fernando Alonso, looks to be far behind its competitors this season. It may not even finish the Australian Grand Prix because of struggles with its new Honda power unit — that's an embarrassing state of affairs for one of the best-funded organizations in the sport.
