10 F1 Technologies That Are Way More Impressive Than They Look

Authored by Mikaelle de Oliveira

An F1 car might look fairly straightforward from the outside: four wheels, a driver and a very loud engine that sounds like it has a personal problem with silence. But underneath the bodywork, there’s a ridiculous amount of technology doing its job every time the car leaves the garage.

The 2026 regulations have pushed some of that technology even further. From wings that can change configuration to power units that recover energy while the car is moving, F1 is full of systems that are easy to overlook when you’re watching the racing.

1. Active Aerodynamics

The 2026 regulations have replaced the old drag reduction system (DRS) with active aerodynamics, which allows parts of the front and rear wings to change configuration. In normal running, the car stays in Z-mode which is its standard higher-downforce configuration. On designated straights, X-mode opens its wings to reduce drag and increase straight line speed.

It means an F1 car isn’t working with exactly the same aerodynamic configuration for an entire lap. The wings can change depending on where the car is on the circuit, helping it maintain downforce through corners before reducing drag on the straights.

2. Hybrid Power Units

The 2026 F1 power unit still combines a 1.6-litre turbocharged V6 with electric power, but the electrical side has now become much more powerful. The MGU-K can now deliver up to 350kW, while the MGU-H has been removed from the power unit.

Energy can be recovered while the car is braking and through other energy recovery strategies before being stored and deployed again. The amount of energy recovered from braking has increased significantly under the 2026 regulations, with the ERS-K able to harvest up to 8.5 megajoules per lap.

There is something crazy about an F1 car effectively recycling some of its own braking energy and then using it to go faster. It feels like the sort of thing that shouldn’t work quite as well as it does.

3. Real-Time Telemetry

An F1 car is basically a rolling data machine. Formula 1 has previously reported that each car can have more than 300 sensors producing around 1.1 million telemetry data points per second. That information helps teams understand how the car is behaving while it’s on track.

The data can also be shared between the circuit and team factories, giving engineers away from the track information they can analyse alongside the people working at the circuit. Basically, while the F1 driver is worrying about the car ahead of them, someone else is worrying about hundreds of things the car is doing underneath them.

4. Driver-In-The-Loop Simulators

F1 simulators are built to replicate the behaviour of a real car and circuit, giving drivers and engineers a way to test changes before they reach the track. Driver-in-the-loop systems allow drivers to interact with a virtual version of the car while engineers assess how different setups and developments affect its behaviour.

Teams can use simulator work to prepare for circuits and investigate setups or development ideas before testing them on a real car.

5. F1 Steering Wheels

An F1 steering wheel is doing a lot more than turning the wheels. It combines steering with displays, paddles, rotary controls and buttons that allow drivers to adjust different aspects of the car while racing.

Drivers can make adjustments such as changing brake balance and other settings without taking their hands away from the wheel. They’re doing all of this while travelling at racing speeds, too. I still have to think twice about which lever controls wipers and which one controls the indicator in a normal car. Now imagine doing that while adjusting brake balance at 200mph.

6. Rolling Road Wind Tunnels

F1 teams spend huge amounts of time studying airflow before aerodynamic upgrades ever reach a circuit. Wind tunnels used for aerodynamic development include a moving belt under the model car, creating a rolling-road effect that helps reproduce the relationship between the car and track.

This is incredibly useful for modern F1 cars because their floors and other aerodynamic surfaces depend heavily on how air moves underneath the car. The moving surface gives engineers a closer representation of what happens when the car is actually travelling along a circuit.

7. Predictive Race Modelling

F1 strategy isn’t just someone staring at a stopwatch and guessing when to pit. Teams are able to use live data and mathematical models to assess possible outcomes involving tyre performance, pit windows, traffic and changing race conditions.

The software doesn’t know exactly what will happen. Instead, it can help teams compare different scenarios and estimate how a decision could affect the race. Of course, a safety car or sudden rain can still throw all those calculations out the window – although Ferrari fans might argue their team sometimes manages that without any help from the weather.

8. Advanced Sustainable Fuel

This year, F1 introduced Advanced Sustainable Fuel across the sport, moving away from newly extracted fossil carbon in its fuel. The FIA says the fuel can be made from sources such as agricultural waste, municipal waste and captured carbon dioxide. Some fuel components can also be produced using renewable energy.

That doesn’t mean every litre is literally made from waste. These sources can be used to produce some of its components, which are then blended into a fuel that can still meet the demands of F1’s high-performance combustion engines. Formula 1 describes it as “drop-in fuel”, meaning it can be used in existing engines without having to make any changes to the engine.

9. Biometric Driver Gloves

The driver’s gloves aren’t only there to protect their hands and give them a good grip on the steering wheel. Sensors built into the gloves monitor the driver’s pulse rate and blood oxygen levels, sending that information to medical crews during a race.

I think this is one of the easiest technologies to miss when watching a race. You see a driver putting on their gloves and probably aren’t thinking about the fact that they’re giving medical teams access to information during an incident.

10. The Halo And Survival Cell

Some of the most important technology in an F1 car is there for the moments nobody wants to see. The survival cell forms a protective structure around the driver, while the titanium halo provides additional protection around their head during a crash.

The survival cell and halo have to be able to withstand enormous forces without adding unnecessary weight to an F1 car, where every kilogram counts. The Halo was heavily criticised when it was first introduced, with some drivers and fans questioning both its appearance and whether F1 really needed it.

Since then, it has played a crucial role in protecting drivers during serious crashes, including Lewis Hamilton at Monza in 2021 and Zhou Guanyu at Silverstone 2022. It’s hard to argue with a piece of technology that has helped keep drivers safe and allowed to carry on doing what they love.

The Technology You Don’t See

Watching an F1 race, we usually just focus on the speed, overtakes and drivers fighting for every position. Behind those few seconds of action is a huge amount of technology helping the car perform at its best.

You see an F1 car fly past in seconds, but every lap is the result of countless calculations, adjustments and engineering decisions. Once you know what’s going on, it’s hard to look at these cars as if they’re just four wheels and an engine.
