F1 cars work like this
Five systems, working together, in about 30 seconds.
- The power unit generates the force. Combustion and an electric motor work together to drive the car forward.
- Aerodynamics presses the car onto the track. Wings and the floor use airflow to create downforce.
- Suspension and tyres deliver that force to the road. Downforce only matters once it reaches the tyre contact patch.
- The brakes control the speed. Slowing down also feeds energy back into the power unit.
- The driver controls it all inside a safety structure. The cockpit, halo and harness protect the driver while all four systems are being managed at once.
AERODYNAMICS
Cornering faster by using the air around the car.
An F1 car's downforce is not only made by the wings you can see. In the current ground-effect era, the parts underneath the car matter just as much.
The underfloor
- Floor (venturi tunnels)
- Diffuser
- Ground effect
These parts are not independent. Air disturbed at the front wing keeps travelling down the car, so what happens at the front affects how well the floor and rear wing work behind it.
Downforce itself is explained in more detail on its own term page.
POWER UNIT
F1 is not driven by the engine alone.
Drive:
Fuel
1.6L V6 Turbo (ICE)
Drives the car
A modern F1 power unit is one system with several parts: the combustion engine, a turbocharger, the MGU-K electric motor and the energy store that supplies it.
2026 CHANGE
- The MGU-H has been removed
- The MGU-K now plays a bigger role
- The electrical system matters more than ever
For how MGU-K and the rest of the power unit work in detail, see its own term page.
TYRES & SUSPENSION
In the end, every force reaches the ground through four tyres.
Acceleration, braking and cornering all ultimately happen between the tyre and the road surface.
Suspension is not only about ride comfort. It is a system that manages several jobs at once.
- Tyre contact
- Chassis movement
- Car attitude
- Aero platform
Tyre compounds and pit stop strategy are covered in more depth in the tyre guide.
BRAKING
A fast car also has to stop well.
- Brake Disc
- Caliper
- Brake-by-Wire
- MGU-K Recovery
Braking in F1 is not only mechanical friction from the discs. It is also linked to the energy recovery system at the rear.
When slowing down, some of that energy is captured and stored rather than being lost as heat.
COCKPIT & SAFETY
The survival structure that surrounds the driver.
It is not just the halo. Several parts together form a single safety system around the driver.
- Survival Cell
- Halo device
- Seat
- Harness
- Headrest
- Steering Wheel
The halo protects the head from debris and side impacts, but the survival cell, harness, seat and headrest work together with it in a crash.

How the parts above connect to what actually happens in a race.
Why the car suddenly understeers
- Front downforce is reduced
- Understeer increases
- Tyre load and balance shift
- Lap time is lost
Damage you cannot see can still cost a lot
- Underfloor airflow changes
- Downforce drops
- Overall balance gets worse, even with no visible damage
Why teams run a skinny wing at circuits like Monza
- Some downforce is given up
- Drag is reduced in return
- The car gains straight-line efficiency, at circuits with long straights
Why a driver deploys electric power at a specific moment
- Available electrical energy and deployment strategy are managed
- That connects to acceleration on the straight
- And it shapes attacking or defending moves
Frequently asked questions
Why is the floor of an F1 car so important?
Since the 2022 regulations reintroduced ground effect, the floor and its venturi tunnels generate a large share of an F1 car's total downforce, often more than the front and rear wings combined. Even damage that looks minor underneath the car can change how the airflow behaves and cost real lap time.
Are an F1 engine and a power unit the same thing?
Not quite. The engine (ICE) is only the 1.6-litre V6 turbo combustion unit. The power unit is the complete system that also includes the MGU-K electric motor, the energy store (battery) and the control electronics that manage how combustion and electrical power work together.
Does an F1 car have suspension like a normal road car?
Yes, every F1 car has a suspension system, but it is tuned very differently from a road car. It is extremely stiff to keep the aerodynamic platform stable and to feed load into the tyres consistently, rather than to maximise ride comfort.
Why does an F1 car have such big wings at the front and back?
The front and rear wings redirect airflow to push the car down onto the track, creating downforce. That extra downward force lets the tyres grip harder in corners, so the car can carry more speed through a bend without sliding.
If every team follows the same rules, why do F1 cars look different?
The technical regulations set boundaries, not a single fixed shape. Inside those limits, teams interpret bodywork, sidepod and floor design differently to chase their own balance of downforce, drag and cooling, which is why cars built to the same rules can still look noticeably different.
