Main Parts of F1 Telemetry Systems
Modern F1 telemetry systems are intricate networks of hardware and software working in harmony to fine-tune energy management. Every component plays a vital role in gathering, transmitting, and analyzing the immense volumes of data that help teams make split-second decisions - decisions that can determine the outcome of a race. Let’s break down the key parts of these systems and how they contribute to energy optimization.
Sensors and Data Collection Tools
F1 cars are equipped with a vast array of sensors designed specifically for energy management. These sensors are grouped into three primary categories: control, instrumentation, and monitoring. Together, they serve as the backbone of energy efficiency tracking, capturing precise data on everything from engine temperatures to the state of the hybrid battery.
Control sensors focus on critical systems like the Energy Recovery System (ERS) and hybrid battery performance. Instrumentation sensors measure things like fuel flow, which is capped at 100 kg/h under current regulations. Meanwhile, monitoring sensors track wear and thermal conditions of components, ensuring the car operates efficiently throughout the race.

For instance, vibration data alone can be captured at rates of up to 200 kilo-samples per second, while other sensors operate at frequencies between 1 Hertz and 1 kilohertz, depending on their purpose. This high-frequency monitoring allows for immediate corrections to energy inefficiencies. During the 2022 Mexico GP, Mercedes collected an astounding 11 terabytes of data over the weekend.
"We generate data from a variety of sources. Primarily it's from sensors on the car itself...right through to things like the operation of the system like the internal state of all sorts of things on the car, like the gearbox."
– Evan Short, Team Leader of Trackside Electronics Systems at Mercedes F1
Data Transmission and Analysis
Once the sensors collect data, it’s transmitted wirelessly to the pit wall for real-time analysis. F1 telemetry systems use frequencies in the 1.45–1.65 GHz range, ensuring steady communication even when cars are flying down the track at over 200 mph. Each lap generates approximately 30 megabytes of live data, which is encrypted to prevent rival teams from intercepting sensitive information.
After transmission, specialized software immediately processes the incoming data. This allows teams to keep tabs on fuel consumption, refine ERS usage strategies, and address potential energy inefficiencies before they become costly. Over the course of a race weekend, a single car can generate more than 1 terabyte of data, including video footage. Advanced AI systems now play a pivotal role in interpreting this data, helping teams fine-tune their energy strategies in real time.

This technology is at the heart of managing Energy Recovery Systems (ERS), fuel strategies, and hybrid powertrain controls.
Energy Recovery Systems (ERS) Management
Telemetry delivers real-time data on critical factors like engine RPM, tire temperatures, and suspension dynamics. This data allows engineers to refine how ERS is deployed, ensuring maximum efficiency. Specialized software processes the incoming data, presenting it in clear visuals that highlight trends and patterns. Machine learning further enhances this process by identifying subtle anomalies or opportunities that might go unnoticed during the intensity of a race. These insights help teams adjust ERS usage based on track conditions, competitor actions, and overall race strategy. In some cases, automated systems tweak car settings on the fly, freeing engineers to focus on broader strategic decisions.
The scale of data involved is staggering. Each F1 car generates over 1 terabyte of data during a race weekend. After additional post-race analysis, this can triple in size. This immense data pool not only helps teams fine-tune car performance but also aids drivers in shaving precious seconds off their lap times.
Fuel Usage Optimization
Telemetry has transformed fuel management into a precise science. By monitoring fuel consumption in real time, engineers can make split-second calls on whether to conserve energy or push for peak performance. Data on fuel levels, engine modes, and race scenarios allows teams to craft detailed fuel-saving strategies. Adjustments to engine mapping and real-time advice on throttle inputs ensure drivers achieve the best possible fuel efficiency.
The results speak for themselves. In 2013, F1 cars consumed around 160 kg of fuel per race. By 2020, this figure dropped to 100 kg, with a goal of reducing it further to 70 kg by 2026. A standout example of telemetry-driven strategy came during the 2019 British Grand Prix. Mercedes used detailed data analysis to time Lewis Hamilton's pit stop perfectly, factoring in fuel consumption, tire wear, and competitor positions during a safety car period. This precision played a key role in securing the win.
Battery and Hybrid System Control
Modern F1 cars rely on hybrid powertrains that combine internal combustion engines with energy recovery systems (ERS). Managing these systems in real time is critical, and telemetry makes it possible. Remote adjustments and AI-driven torque vectoring allow teams to balance performance and energy efficiency dynamically. Engineers can control when and how the electric boost is deployed - whether to gain a competitive edge on the track or to defend a position.
This level of control is made possible by hundreds of sensors monitoring everything from engine pressures and temperatures to tire conditions and even driver biometrics. Each car produces about 1.1 million data points during a race, which are sent directly to the pit wall. Engineers use this information to make rapid decisions, adjusting hybrid systems multiple times per lap to respond to changing track conditions, tire wear, and race dynamics.
These real-time adjustments have redefined racing strategies. Teams now orchestrate an intricate balance, ensuring every component of the car works together to maximize performance while adhering to strict energy regulations. This kind of precision underscores F1’s commitment to pushing the boundaries of energy efficiency.
Using Telemetry for Real-Time Race Strategy
Real-time telemetry has revolutionized how Formula 1 teams make split-second decisions, turning them into precise, energy-conscious race strategies. With over 300 sensors on each car producing 35 megabytes of raw telemetry data per lap [12, 25], teams rely on this constant flow of information to adapt strategies and guide on-track decisions effectively.
Changing Race Strategy During the Race
In a race where conditions can shift in an instant, telemetry data is the backbone of strategic adjustments. Teams track over a thousand real-time data points, including throttle inputs, lateral G-forces, tire conditions, and energy usage, to make immediate changes to their approach.
"Each car transmits over a thousand live telemetry points, allowing engineers to track throttle position, lateral G-forces, tire temps, and energy deployment in real time. This data is analyzed instantaneously to guide pit stop decisions, tire management, and on-the-fly strategy changes." (LinkedIn)
When weather or track conditions change unexpectedly, engineers use telemetry to recalibrate energy deployment and adjust strategies on the spot. For example, by studying tire wear and degradation rates, teams can decide whether to stick to the original energy plan or shift focus. If tire performance declines faster than anticipated, they might lean more on electric power to extend tire life without compromising speed.
Fuel management also plays a key role, particularly during safety car periods or unexpected incidents. Real-time fuel consumption data allows teams to decide whether to extend stints or tweak power output strategies without jeopardizing the race.
Remote Monitoring and Decision-Making
Modern F1 teams don’t just rely on the trackside garage; they’re supported by remote operations that analyze data in real time. While engineers at the circuit focus on immediate decisions, off-site teams dive deeper into performance trends and long-term optimizations.
Remote teams monitor engine metrics like RPM, turbo pressure, and temperature to spot opportunities for improved performance that might not be obvious from lap-by-lap data. They also analyze aerodynamic data - such as airflow and pressure readings - to suggest adjustments that can reduce drag or increase downforce as conditions evolve. These insights are quickly relayed to the pit wall, enabling real-time tweaks to car setup or strategy.
Preventing Energy-Related Problems
Telemetry isn’t just about strategy - it’s also a critical tool for avoiding mechanical failures. By continuously monitoring every system on the car, teams can identify potential issues before they escalate into race-ending problems. With data sampled thousands of times per second, even the smallest anomalies can be flagged early.
For instance, telemetry tracks battery temperatures, charge levels, and discharge rates, allowing teams to implement cooling measures before overheating becomes an issue. Adjustments to energy deployment or driving techniques can reduce stress on hybrid systems and keep the car running smoothly.
Telemetry also monitors fuel flow and consumption patterns, immediately highlighting any irregularities for investigation. Engine health is under constant watch, with data revealing early signs of component stress. When parts approach their limits, teams can adjust settings to reduce engine strain, ensuring reliability throughout the race. These proactive measures are crucial for staying competitive and avoiding costly retirements.
