A modern Formula 1 car carries around 300 sensors. Every lap, those sensors push roughly 1.1 million telemetry data points per second back to the pit wall. Over a single Grand Prix weekend, a top team processes close to 160 terabytes of data.
That number is the reason this post exists. Racing is still about drivers, engines, and aerodynamics. But the thing that decides whether a strategy call works, whether a fuel map is safe, whether a suspension change is pointing the right direction — that's electronics.
We researched 25 companies that sit behind the cars you watch on Sundays.
Digi Hotshot is a Webflow agency. We've built 50+ sites for SaaS, fintech, healthcare, and defense-tech companies since 2019. We have zero motorsport clients.
Parth (founder) studied automobile engineering before moving into web. The engineering instinct — systems thinking, tolerances, how a sensor spec becomes a CAN message becomes a dashboard readout — sits closer to how this supplier base works than most of the SaaS world we serve day-to-day.
We're also mapping engineering-heavy industries as part of a longer research project on how technical companies present themselves online. Motorsport electronics is one of the most interesting slices of that project. The websites in this space are a study in contrasts. Some are crisp. Most are stuck in 2012.
We worked off public sources — company websites, published FIA technical regulations, motorsport trade publications, LinkedIn company pages, and race engineering literature. Every company in the list has a live website we verified, a country of record, and a product line clearly tied to motorsport.
We group the 25 into five buckets: Data acquisition and telemetry, ECUs and engine management, Sensors and transducers, Connectors and harnessing, and specialty instrumentation.
This is the layer that turns sensor voltages into decisions. Loggers, dashes, telemetry radios, and the software that engineers actually stare at during a session.
Cosworth's electronics division operates out of Cambridge and Indianapolis. They build powertrain controllers, data loggers, FIA-homologated hardware, and racing steering wheels. Their Pi Toolbox analysis software is used across F1, IndyCar, WEC, WRC, Super Formula, and BTCC. In August 2025 Cosworth partnered with iRacing to bring Pi Toolbox into sim racing.
Motion Applied is the new name for what used to be McLaren Applied, a descendant of TAG Electronic Systems (founded 1989). The company rebranded in 2025 after completing its separation from McLaren. Over 35 years of F1 heritage — for years they were the sole supplier of the F1 standard ECU.
MoTeC is the most recognised name in motorsport data acquisition outside of Europe. Founded in 1987, it was the first company to bring data logging and live telemetry to Australian racing. Their M800 ECU has been a reference product for decades. Bosch acquired MoTeC in September 2022.
Pi Research was the original name behind Pi Toolbox, once a standalone British data acquisition company that supplied F1 teams through the 1990s and 2000s. The hardware and software passed into Cosworth's electronics portfolio.
2D Datarecording has built motorsport data acquisition systems out of Karlsruhe since 1993. Particularly well known in two-wheeled racing — MotoGP teams have used their kit for years — but they also serve F1 customers and several automotive manufacturer test programmes.
AiM operates from Italy with distribution across Europe, the US, and Asia-Pacific. Their product line covers data loggers, dashes, and steering wheel displays. The brand is aggressive about covering every price point from sub-$500 GPS lap timers to full pro data systems.
Based in Derbyshire, Race Technology builds data loggers and electronic scrutineering systems. They have a specific niche — working with sanctioning bodies on rule enforcement and Balance of Performance (BoP) hardware for international championships.
Stack has been building motorsport instrumentation out of the UK since 1986. Their product line covers tachometers, driver displays, data logging, and synchronised video logging. They also sell a battery-less tyre pressure monitoring system popular in touring car and GT racing.
The box that decides how much fuel goes in, when the spark fires, and when the gearbox shifts. Motorsport ECUs are their own world — they look nothing like a road car ECU and cost roughly ten times as much.
Bosch Motorsport operates out of Abstatt, Germany. The scope is the widest of any supplier in this list: ECUs for petrol and diesel race engines, vehicle control units, data loggers, telemetry, and a full sensor catalogue. They also own MoTeC, giving the group a dominant position in professional motorsport electronics worldwide.
Marelli has more than 100 years of motorsport history. Their motorsport division builds ECUs, KERS and hybrid control units, dashboard displays, and telemetry systems. Most recently signed as a technical partner with Toyota Racing in the FIA World Endurance Championship.
Life Racing was founded in 2002 in Basildon, Essex, specifically to build ECUs for professional motor racing, OEM automotive suppliers, and military customers. Their F88 and F90 series ECUs are common in prototype and GT racing.
Syvecs builds engine management on top of Life Racing's hardware architecture. The S7-Plus and S8 platforms are used across rally, hill climb, touring cars, endurance, and a growing number of plug-and-play packages for modified road cars.
GEMS is one of the older motorsport electronics brands still trading. They build engine management, transmission control, data acquisition, and in-car display systems, and have historically supplied top touring car and sportscar teams.
Geartronics makes paddleshift and flatshift systems for sequential gearboxes — compatible with Hewland, Quaife, Ricardo, and Xtrac. Trading since 2001. A clean example of a company actively shipping product while running a site that looks untouched since 2005.
This is the deepest and most fragmented category. Every one of those 300 sensors on an F1 car comes from a supplier.
Texense is the motorsport sensor arm of the Texys Group, based in France and founded by a former head of electronics at an F1 team. Their sensor range covers accelerometers, brake and caliper temperature, fluid temperature, force measurement, and wheel speed sensors. Texys has been appointed sole TPMS supplier for FIA Formula E from 2023 through 2026.
Variohm has been designing sensors out of the UK since 1974. The motorsport catalogue covers linear and rotary position, piezo-resistive pressure, IR and resistive temperature, wheel speed, accelerometers, and gyros. Customers span F1, A1GP, WTCC, GP2, NASCAR, ALMS, and Superbike.
Founded in 1956, acquired by Curtiss-Wright in 2002. Their TPS280DP throttle position sensor has a tested life of over 60 million operations. Their sensors have been on every winning F1 car since 1986.
Active Sensors makes position sensors for motion control and measurement. All of their motorsport sensor products are FIA-homologated for F1 use — linear and rotary position sensors, AC and DC LVDTs, tilt, speed, and accelerometers.
Reventec runs out of Wiltshire and uses quantum tunnelling magnetoresistive (TMR) technology for contactless position sensing. One of the companies F1 teams are leaning on for the 2026 active aerodynamics regulations. Their product line includes DRS rear wing actuator sensors, F1 brake master cylinder position sensors, and steering position sensors.
Sentronics builds ultrasonic flow meters out of Downton, Salisbury. Their FlowSonic Sport is an FIA-homologated F1 ultrasonic fuel flow meter. One of a very small number of companies that clears both the governing body and team bars for fuel flow measurement.
Founded in Winterthur in 1959, Kistler is the global reference for dynamic measurement of pressure, force, torque, and acceleration. Their Correvit optical sensors are used in F1, NASCAR, MotoGP, Formula E, and autonomous racing as the "ground truth" against which other sensors are compared.
Grew out of Sony Magnescale, founded in 1969 in Tokyo. Their precision magnetic position measurement technology is a specialist option for engine test rigs and chassis measurement work inside racing teams. The only Japanese company in this list.
Honeywell is not a motorsport company, but their pressure sensor line has become a common sight in race car fuel, oil, coolant, and boost pressure monitoring. The all-stainless body and linear output make them a clean fit with aftermarket ECUs and data loggers.
A race car harness is a piece of sculpture that happens to carry electricity. The connectors and cables in it come from a very small number of companies.
TE Connectivity owns the DEUTSCH Autosport connector family and the Raychem wire and heat-shrink lines, which together form the backbone of almost every pro motorsport wiring harness on the grid. TE recently released a DEUTSCH Autosport hermetic fuel tank connector range with a 60% weight saving over stainless steel.
LEMO has been building push-pull connectors since 1946 in Switzerland. The LEMO connector is a common sight on steering wheels, driver radio systems, and pit garage test rigs. 79-year trading history.
This post is about motorsport, but the pattern it describes isn't unique to motorsport. It shows up in semiconductor suppliers, in industrial sensor companies, in defence-tech contractors, in anyone selling a physically engineered product to a technical buyer. The product is genuinely deep. The website is a decade behind. The content is buried in a datasheet.
F1 electronics is supplied by a small group of specialist companies working inside the FIA's technical regulations. The standard ECU has historically been supplied by McLaren Applied (now Motion Applied), with Bosch Motorsport as a major alternative. Sensor suppliers include Texense, Variohm Eurosensor, Penny + Giles, Active Sensors, Reventec, and Kistler. Connectors come primarily from TE Connectivity's DEUTSCH Autosport line and LEMO.
Motorsport data acquisition is the process of recording signals from sensors on a race car — suspension travel, tyre pressure, engine RPM, brake pressure, G-forces, GPS position, and hundreds of others — and logging them for analysis. A typical professional system records at 100 Hz to 5,000 Hz per channel across hundreds of channels simultaneously.
A modern F1 car runs around 300 sensors, generating roughly 1.1 million telemetry data points per second. Over a race weekend, a top team processes close to 160 terabytes of data.
A motorsport ECU is programmable at a much deeper level, logs many more channels at higher frequencies, and supports strategies like launch control, anti-lag, traction control, and advanced fuel strategy. They're also physically smaller, lighter, sealed against fluids and vibration, and cost 10–20 times more than a factory ECU.
The UK hosts Motorsport Valley — a cluster of racing teams and suppliers concentrated around Northamptonshire, Oxfordshire, and the Midlands. Seven of the ten F1 teams are based in this region. The supplier base grew around those teams over four decades, and it never moved.
Yes, if you're racing in a series that requires it. F1, WEC, and some FIA-sanctioned championships specify homologated sensors for certain measurements — fuel flow, position sensing on safety-critical systems, and crash recorders. Outside those specific applications, teams are free to choose non-homologated sensors.
