Why care about F1 tech? Not only does the engineering behind these roughly 1,000-horsepower machines find its way into everyday cars, but the rapid-paced R&D in Formula 1 often drives cross-industry breakthroughs in materials science and high-efficiency manufacturing methods. R&D professionals can observe how F1 teams iterate prototypes in days rather than months. The field also provides a case study on how to push the limits of lightweight structures—all under intense budget and regulatory constraints. These same strategies and technologies apply to other R&D heavy industries, including aerospace, consumer electronics, medical devices and more.
Let’s explore several of the key technological domains where Formula 1’s engineering initiatives demonstrate this acceleration of innovation, starting with perhaps the most visually distinctive aspect of these vehicles, their aerodynamic architecture:
1. Active aero and ground effect to maximize downforce
Formula 1’s latest cars feature aerodynamic designs that prioritize ground effect downforce and limited active elements to improve racing. While ground effect was banned in F1 in 1982, the 2022 regulation overhaul reintroduced ground effect via fully shaped venturi tunnels under the car. The result is the generation of large amounts of efficient downforce with less reliance on complex top-body winglets.
As an F1 video explains, “Downforce is a vertical aerodynamic force acting on a car as the car moves forward traveling through the air. The downforce pushes the car towards the ground, effectively the opposite of what lifts a plane into the air on takeoff.” The video goes on to note that when a car is traveling at around 150 kmph (about 93 mph), the downforce on the car is in a similar ballpark to the minimum weight of an F1 car, or about 795 kg (1,753 lbs). “At max speed, that force is over five times as powerful,” the video notes.
In other words, ground effect aims to create an effect along the underside of the car that can expand the air flow passing underneath as it moves from front to back, resulting in an area of low pressure that sinks the car down towards the ground. In turn, this increases the grip of tires, which translates to more speed and control through corners.
The functionality aims to reduce turbulent wake and allow cars to follow more closely, addressing “dirty air.” In essence, dirty air doesn’t refer to particles in the air but refers to when one car follows another closely. As the F1 video notes, “As the leading car cuts through the air, it distributes the air away, meaning the car behind doesn’t have the same amount of air-related forces to work with, impacting the ability to produce downforce, grip, and traction.”
These aerodynamic principles drove the FIA’s regulatory direction, pushing teams toward ground effect approaches that fundamentally altered the sport’s competitive dynamics. By generating downforce from the floor rather than wings and bodywork, cars could maintain performance while producing less disruptive wake behind them. All teams embraced these venturi-floor concepts, though some initially struggled with “porpoising” (bouncing caused by fluctuating ground effect). The FIA intervened mid-2022 with technical directives (e.g. minimum floor heights and stiffness) to curb that problem.
2. Drag reduction systems
Modern F1 cars also have a driver-activated aerodynamic device: DRS (Drag Reduction System). DRS opens a flap in the rear wing on straights to reduce drag and boost overtaking. Teams continually refine their wing designs for maximum DRS advantage — for example, Red Bull’s 2023 car featured a clever diffuser and beam wing design that achieved a greater air stall when DRS opened, giving them top-speed gains (See: Secrets of Red Bull’s RB19 with Adrian Newey – The Race). In contrast, Mercedes experimented with a radical “zero sidepod” aero package in 2022 to reduce drag, but had to revise it after stability hurdles.
Looking ahead, F1 plans to expand active aerodynamics under the 2026 rules. Movable front and rear wing elements will allow drivers to toggle between high-downforce and low-drag modes, dubbed “Z-mode” and “X-mode.” In Z-mode the wings generate maximum downforce for cornering, while X-mode reconfigures them for minimal drag on straights – essentially an enhanced, automated evolution of DRS. These active aero systems will be restricted to safe zones (e.g. any straight longer than ~3 seconds) and controlled by the FIA, reflecting how regulations enable innovation (to boost efficiency and overtaking) but within safety limits. Overall, aerodynamic R&D in F1 remains intense. It ranges from subtle winglet tweaks to major floor concept changes.

3. Hybrid power units and energy recovery systems
Today’s F1 power units are turbo-hybrid systems combining a 1.6-liter V6 internal combustion engine (ICE) with electric motor-generators for energy recovery. These hybrid designs, introduced in 2014, have matured into the most efficient racing engines. The ERS includes an MGU-K (motor-generator unit kinetic) that harvests braking energy and an MGU-H (heat unit) that recovers energy from turbocharger heat, plus a battery pack to store and deploy energy. Teams like Mercedes and Ferrari have iterated heavily on this technology – for instance, Ferrari’s 2022 engine (Tipo 066/7) was all-new with an improved hybrid system carried over from late-2021, which helped them regain top-end power, as Formula 1 has noted. The result is ~1000+ horsepower performance using far less fuel than past engines. In 2013 a car used about 160 kg of fuel per race; by 2020 it was 100 kg, and the goal for 2026 is only 70 kg per race.
In 2009, Kimi Räikkönen assumed the lead of the 2009 Belgian Grand Prix after overtaking rivals with a kinetic energy recovery system (KERS). He eventually won the race.
Energy recovery is critical: current rules allow deploying 4 MJ of stored energy per lap (in the ballpark of 120 kW from the MGU-K). Teams optimize when and how this electric boost is used for lap time or defense. The MGU-H, although technically impressive (it can both generate power from exhaust and eliminate turbo lag by spinning the turbo electrically), will be dropped in the upcoming 2026 regulations. The stated reason is to simplify systems and attract new manufacturers. Starting in 2023, engine development was essentially frozen by FIA rules (aside from reliability tweaks) to cut costs, which shifts team focus to software, ERS tuning, and integration improvements. Despite that freeze, reliability and clever energy management still differentiate the manufacturers – e.g. Red Bull’s Honda (now Red Bull Powertrains) solved early hybrid reliability issues to win titles, while Ferrari had to dial back their hybrid deployment at times for reliability in 2022.
In 2026, a new engine formula will up the electrical output and emphasize sustainability. The MGU-K’s output will nearly triple to about 350 kW (See: 7 things you need to know about the 2026 F1 engine regulations | Formula 1®). That means a roughly 50/50 power split between electric and combustion sources. With more braking energy recovered and no MGU-H, drivers and engineers will need to navigate deploying electric boost versus managing likely turbo lag. The fuel will be a 100% sustainable synthetic fuel (no fossil carbon) an engine cost cap plus standardized components will contain expenses.
4. Advanced materials and lightweight construction
Weight is the enemy of performance, so F1 teams pursue lightweight, strong materials and constructions. Carbon fiber composites are frequently the backbone of F1 car design. They thus comprise a significant share of the F1 car’s materials by volume at INEOS, for instance, which is a principal partner of the Mercedes-AMG PETRONAS Formula One Team. The entire chassis (monocoque) and much of the bodywork and wings of F1 cars are thus made of carbon fiber. Other composites and aramid fibers (Kevlar, Zylon) are used in critical areas for toughness and safety. For example, Zylon anti-penetration panels line the cockpit sides to prevent debris intrusion. Titanium often finds use for the halo cockpit protection and various fasteners for its strength, while heat-resistant alloys (Inconel, etc.) appear in the exhaust and braking systems. Over the years, teams have introduced new weave techniques like spread-tow carbon fabrics that can save significant weight versus traditional carbon layups, according to Piran Composites.

Recently, there’s a push for sustainable materials without sacrificing performance. For instance, McLaren has pioneered the use of a natural flax-fiber composite for an F1 seat, which debuted in 2021. This bio-composite met the required stiffness while reducing the part’s carbon footprint by 75%, according to Piran Composites. In 2023, McLaren also became the first team to run recycled carbon fiber elements on its car (non-critical parts like cockpit branding panels) as part of a long-term goal toward a circular, waste-free car manufacturing process, as it noted on its website. Mercedes, meanwhile, has plans to introduce sustainable carbon fiber composites on its 2025 car through a partnership with materials suppliers, given that such composites dominate their car’s makeup, according to INEOS.
Construction methods are also evolving. All teams employ advanced additive manufacturing (3D printing) for rapid prototyping and even race-ready parts (for instance, lightweight titanium or carbon fiber-reinforced components). Aston Martin’s brand-new factory includes additive manufacturing machines to quickly produce and test 60% scale wind tunnel models and even some full-size parts. This agility in making iteratively improved components helps teams stay under the cost cap and respond to issues faster. Even paint is scrutinized. In 2022–2023 several teams ran cars with minimal paint or matte finishes to save a few hundred grams. The minimum weight limit (currently around 798 kg including driver) is enforced by FIA rules. But teams fight to get every kilogram under that limit so they can add ballast in ideal locations for balance. In short, F1 engineers exploit every material science advance possible, from new composite resins to 3D-printed metal parts, to build lighter, stronger cars.
5. AI and machine learning simulations help prep for races, and more
Modern F1 teams are as much data companies as racing outfits. They are tapping AI and machine learning to crunch vast amounts of data for strategic and performance gains. During a Grand Prix weekend, for instance, teams run AI-powered simulations modeling scores of potential race scenarios and parameters. These models factor in weather forecasts, tire degradation patterns, competitor behavior, crash probabilities, and more to help strategists decide the optimal pit stop windows and race tactics. For example, machine learning models can evaluate the outcome of an early safety car or predict how battling another car might affect tire temperatures, allowing the team to make quicker, more informed calls.

In terms of operations, top teams have formed technical partnerships for big data and AI. McLaren, for instance, works with Dell and Google Cloud to power its simulations and analytics, streaming data from car to cloud in real time. One McLaren system can stream 100,000 data points per second from the car to build accurate digital models for performance analysis. Mercedes employed machine-learning analytics via a partnership with TIBCO to turn live race data into strategy insights. And Oracle’s cloud computing enables Red Bull Racing to run Monte Carlo simulations for strategy and car development.
FIA regulations prevent AI from overtaking the human element on track. Drivers must still drive the car and thus no self-driving or automated driver aids, and teams cannot control the car remotely. Yet off-track there are no such limits: teams run as many virtual races as needed in search of optimal strategies. Some research even explores reinforcement learning algorithms to autonomously devise race strategies in simulation.
6. Data telemetry and real-time monitoring
F1 teams’ decision-making hinges on data telemetry – live data transmitted from the car to the pits (and even to remote factories) throughout each session. Today’s F1 cars are equipped with an array of hundreds of sensors measuring everything from engine pressures and temperatures to suspension travel, tire pressure and even driver biometric data. This generates large volumes of data: on the order of 1 terabyte per car per race weekend or more. Teams use high-bandwidth radio systems to send telemetry in real time to the garage, where engineers monitor the car’s health and performance on multiple screens.
High-speed telemetry feeds enable engineers to see metrics like fuel consumption, brake wear, or battery energy state corner-by-corner and make instantaneous strategy adjustments. If a tire’s pressure sensor flags a slow puncture, the pit wall can call the driver in before a blowout. If brake temperatures spike, brake ducts can be adjusted at the next pit stop.

As organizations like McLaren experiment with race-tested flax-fiber seats that slash carbon footprints and Mercedes develops sustainable composites for 2025, they’re conducting a similar sort of materials science experimentation as aerospace and medical researchers, just at speeds reaching up to 350 km/h (217 mph).
