Precision Engineering: Allengra's Cutting-Edge Fuel Flow Technology Set to Transform F1 Monitoring
The FIA has selected Allengra as the sole supplier for fuel flow measurement in Formula 1's upcoming power unit era from 2026 to 2030. The German-Romanian technology promises unprecedented accuracy in monitoring fuel consumption and flow rates during races.

As Formula 1 prepares for its next technological frontier, Allengra emerges as a critical player in the sport's ongoing quest for precise performance measurement. The company, combining German engineering expertise with Romanian technological innovation, has secured an exclusive contract to provide fuel flow meters for the 2026-2030 power unit regulations.
The fuel flow meter represents a crucial component in F1's stringent technical regulations, designed to ensure fair competition and technological compliance. Teams are currently limited to a maximum fuel flow rate of 100 kg per hour, a rule that demands extraordinary measuring precision.
Allengra's technology is expected to bring several key advantages to the championship. Their meter will likely utilize advanced sensor technologies and real-time data processing capabilities, allowing instantaneous detection of any potential fuel flow irregularities. This means teams will face immediate scrutiny, reducing opportunities for strategic circumvention of technical regulations.
The selection process was undoubtedly rigorous, with the FIA requiring a solution that could provide millimeter-perfect accuracy across extreme racing conditions. Allengra's successful bid suggests their technology can withstand the punishing environments of high-speed motorsport, including intense temperatures, vibrations, and rapid pressure changes.
While specific technical details remain confidential, the partnership signals F1's commitment to technological transparency and fair competition. Teams will need to adapt their fuel management strategies to work seamlessly with this new monitoring system, potentially influencing power unit design and race strategy.
As the 2026 regulations approach, all eyes will be on how Allengra's fuel flow meters will reshape the intricate technological landscape of Formula 1 racing.

Full Regulation Text
Article C5.9.3
Fuel Flow Meter requirement
Chapter: C5
In Simple Terms
Every F1 car must have a device that measures fuel flow, and this device must be located inside the fuel tank. Teams are not allowed to heat or cool this meter intentionally, as doing so could affect its accuracy and give them an unfair advantage.
- Fuel Flow Meter must be physically located entirely within the fuel tank
- Any intentional heating or cooling of the meter is strictly forbidden
- The rule ensures fair fuel consumption monitoring across all teams
- Violations represent an attempt to circumvent fuel flow regulations
Official FIA Text
All cars must be fitted with a Fuel Flow Meter wholly within the fuel tank. Any intentional heating or chilling of the Fuel Flow Meter is forbidden.
Article 10B
Fuel Flow Meter
Chapter: C5.9.3
In Simple Terms
F1 teams must use official fuel flow meters approved by the FIA to monitor how much fuel is being used during a race. These meters come with specific fittings, hoses, and pipes that are standardized to ensure fair competition and prevent teams from gaining an advantage by using unauthorized equipment.
- Teams must use FIA-prescribed fuel flow meters, not custom alternatives
- All fittings, hoses, and pipes must be from the official specification
- Proper mounting and installation of fuel flow measurement equipment is mandatory
- This regulation ensures all teams have equal fuel consumption monitoring capabilities

Article C5.2.3
Fuel Energy Flow Maximum
Chapter: C5
In Simple Terms
F1 cars have a limit on how much energy they can get from their fuel per hour of racing. This rule ensures all teams use fuel efficiently and prevents any team from gaining an unfair power advantage by burning fuel faster than allowed. The maximum allowed rate is 3000 megajoules per hour.
- Fuel energy flow is capped at 3000MJ/h to promote fair competition
- This regulation encourages efficient fuel consumption and energy management
- Teams must monitor and control their fuel burn rate throughout the race
- Exceeding this limit is a technical regulation breach with sporting penalties
Official FIA Text
Fuel energy flow must not exceed 3000MJ/h.
