The 2026 F1 power unit is tracked as separate regulated elements. A driver does not receive one unlimited “engine”; the FIA records the individual components that enter the driver's season pool.

What happens if they exceed the pool? The first extra element of a type brings a 10-place grid penalty. Later additional elements of that same type bring 5-place grid penalties. Penalties at the same event are cumulative; if the total exceeds 15 grid places, the driver must start the race from the back.

For 2026, Formula 1 introduced full-time active aerodynamics. Both the front and rear wings can change configuration depending on where the car is on the circuit.

• Straight Mode: the wing flaps move to a low-drag position on straights, helping top speed.
• Corner Mode: the wings return to a higher-downforce configuration for grip in corners.
• Recharge: energy-management behavior that helps replenish electrical energy.
• Boost: electrical deployment available to the driver within the 2026 system.
• Overtake Mode: an additional overtaking-related electrical deployment tool under the 2026 rules.

On a normal 2026 Grand Prix weekend, Pirelli typically provides each driver with 13 sets of dry-weather tires: 2 hard, 3 medium and 8 soft. Intermediate and full-wet tires are also available for wet conditions.

Drivers reaching Q3 receive access to an extra soft set reserved for that purpose. In a dry Grand Prix, drivers must use at least two different slick compounds during the race.

This is why a team may deliberately protect a tire set in practice or qualifying: every fresh set can have strategic value later.

A pit stop buys fresh tires but costs significant track time. Engineers compare the expected lap-time gain from new tires against the time lost entering the pit lane, stopping, changing tires and rejoining traffic.

• Undercut: pit earlier than a rival, use fresh-tire pace, and try to jump them when they stop.
• Overcut: stay out longer and hope clear air, old-tire pace or traffic works in your favor.
• Track position: at a circuit where passing is difficult, staying ahead can be worth more than having fresher tires.
• Safety Car risk: a later caution can make a pit stop much cheaper and completely reverse the strategy.

A “slow” lap can therefore be intentional tire management, fuel saving, battery charging or preparation for a later attack.

Safety Car: the field physically gathers behind the Safety Car. Gaps between cars shrink, and the relative time cost of a pit stop can fall dramatically.

Virtual Safety Car (VSC): drivers must respect a controlled reduced pace rather than all queueing behind one physical car. Most gaps are therefore preserved more closely than under a full Safety Car.

• Teams may pit immediately because the time loss is reduced.
• A driver who had built a large lead can lose much of that advantage under a full Safety Car.
• Restarts create tire-temperature, brake-temperature and overtaking challenges.
• Drivers may weave or brake deliberately to maintain temperature before racing resumes.

Formula 2 is a one-make championship: all 22 cars are built to the same Dallara specification and use the same Mecachrome power unit. That reduces the huge design-development differences seen between F1 constructors and puts more emphasis on the driver, setup and team execution.

Formula 3 is another one-make development category, but it is lower in the performance ladder than F2. All 30 cars share the same core Dallara/Mecachrome specification.
