Automotive Brake-by-Wire Systems Market Size, CAGR & Forecast, 2025-2035

Dry electromechanical braking moves the brake-by-wire market from niche to volume by 2035

Valued at USD 8.65 Billion in 2025, the global automotive brake-by-wire systems market is projected to reach USD 9.72 Billion in 2026 and USD 27.84 Billion by 2035, a CAGR of 12.40%.

Radial Insights defines the Automotive Brake-by-Wire Systems market as factory and service revenue from braking systems in which driver pedal input reaches the brake actuators as an electrical signal instead of through a direct hydraulic or mechanical link. Scope covers electro-hydraulic one-box units such as Bosch IPB, ZF IBC and Aumovio MK C2, two-box combinations of an electric booster with a separate stability module, hybrid architectures that use electromechanical calipers on the rear axle, and fully dry electromechanical brakes (EMB) at all four wheels. We exclude conventional vacuum boosters, standalone ABS and ESC modules, electronic parking brakes sold on their own, and friction materials such as pads and rotors, which Radial Insights tracks in separate studies.

Growth comes from three things that arrived together in 2025 and 2026: more than 20 million electric cars sold in 2025 according to the IEA, a Chinese braking standard (GB 21670-2025) that sets rules for electrically transmitted braking, and the first series programs for fluid-free systems from Brembo and Chery. Electric drivetrains need blended regenerative and friction braking, and software-defined vehicles need brakes that can be commanded by driver assistance and automated driving stacks. Brake-by-wire answers both.

Dry electromechanical brakes are the fastest technology segment, expanding at 31.60% a year from a small base, while electro-hydraulic one-box systems remain the largest revenue pool through the forecast. Asia Pacific (APAC) is both the largest and the fastest region, with a 13.30% CAGR, led by Chinese EV makers that are moving quickly to EMB.

The Automotive Brake-by-Wire Systems market still faces cost, validation and liability barriers. Even so, our forecast has almost every new battery electric platform launched after 2028 using some form of brake-by-wire, which explains why revenue roughly triples over the decade.

Hybrid and fully dry architectures grow two to three times faster than the market

We split the automotive brake-by-wire systems market along five dimensions. The table shows each segment's growth rate for 2025-2035. Segment sizes are not published in this summary.

One-box electro-hydraulic units still lead, but EMB is gaining fastest

Electro-hydraulic one-box systems such as Bosch IPB, ZF IBC and Aumovio MK C2 combine pedal simulation, pressure generation and stability control in one housing. They hold the largest revenue base because they have been in series production since 2018 and fit existing hydraulic calipers. Their 10.20% CAGR trails the market because new programs shift to hybrid and dry layouts. Hybrid systems, which pair rear electromechanical calipers with front hydraulic brakes, grow at 24.80% because they suit heavy US pickups and SUVs that need high front clamping force. Fully dry EMB grows at 31.60% as Chinese carmakers, led by Chery's Exeed EX7, put four-wheel EMB into production. Two-box systems grow slowest at 6.40% as OEMs consolidate hardware.

Software and control units take a rising share of value

Brake control units and software expand at 13.90%, ahead of hardware, because redundant processors, dual power supplies and over-the-air calibration add content per vehicle. Wheel and central actuators grow at 12.80%, pulled up by EMB, which places a motor and gear set at each corner. Pedal feel simulators and sensors grow at 11.70%. Hydraulic modulators grow only 7.30% because dry systems remove them altogether.

Battery electric vehicles set the pace among propulsion types

Battery electric vehicles post a 15.60% CAGR because maximum regenerative braking needs a decoupled pedal, and vacuum sources are absent. Plug-in hybrid and range-extended vehicles follow at 13.10%, a fast-growing type in China. Full and mild hybrids grow at 9.40%. Internal combustion vehicles grow at just 4.10%, mostly through premium models that adopt one-box units for automated emergency braking.

Commercial vehicles grow from a small base

Passenger cars account for most revenue and grow at 12.10%. Light commercial vehicles grow at 13.70% as electric vans adopt one-box units. Medium and heavy commercial vehicles grow fastest at 16.20%, as Haldex and ZF develop electromechanical brakes for electric trucks and trailers. The base is small because air brakes still dominate heavy vehicles.

OEM fitment captures nearly all revenue

OEM fitment grows at 12.60% and carries most revenue because brake-by-wire is designed into a platform. Aftermarket and service replacement grows at 8.90%: actuators, sensors and control units must be replaced after collisions or failures, but the installed base is still young.

Market Trends

Fluid-free braking enters series production

In May 2026, Brembo said its Sensify system had entered series production with a leading global vehicle manufacturer, fitted on 100% of vehicles in the program. Brembo expects the program to run at hundreds of thousands of vehicles a year. In February 2026, Chery said the Exeed EX7 would be the first mass-production car with fully electronic EMB brakes. The car was scheduled to launch on April 17, 2026. Together, these two programs mark the move of dry braking from prototype to production line.

Suppliers offer both hybrid and fully dry systems

In July 2025, ZF presented two brake-by-wire layouts: a fully dry system with EMB at all four wheels, and a hybrid with EMB on the rear axle aimed at US pickups and heavy light trucks. ZF says demand for dry systems has risen sharply, especially in Asia. Earlier, in January 2025, ZF announced a brake-by-wire order for nearly 5 million vehicles from a global OEM, using the hybrid design. Nexteer launched its own EMB system in April 2025 and showed it at Auto Shanghai.

Regulation catches up with electrical transmission braking

China issued GB 21670-2025 in May 2025. It sets requirements for electrically transmitted braking, including redundancy and safety validation. At UNECE, the GRVA working party discussed industry proposals during 2025 to amend UN R13 and R13-H for electrical transmission braking and periodic inspection. A clear approval path lowers risk for OEMs and is one reason Chinese suppliers such as Orient-Motion and Jiongyi Electronic were preparing EMB for 2026 mass production.

Large multi-year sourcing awards lock in suppliers

In July 2026, Aumovio, the former Continental automotive business, and BMW signed a deal worth more than EUR 1 billion. It covers the MK C2 one-box brake, with series deliveries until the mid-2030s, plus calipers and electronics. Bosch said in October 2025 that its by-wire brake actuator would enter production with an Asian carmaker in early 2026. Awards of this size and length mean the supplier ranking for 2030 is already largely fixed.

Restraints and Challenges

Liability and quality risk is high

A brake fault is a safety issue, and recalls are costly. In July 2026, Aumovio said it would pay EUR 350 million to settle legal proceedings over an earlier integrated brake system, in the same release announcing its BMW brake order. Settlements of this size push OEMs to demand longer validation and more redundancy, which slows launches and adds cost.

Redundancy adds cost per vehicle

A brake-by-wire system needs fault tolerance. Bosch's by-wire actuator uses redundant signal lines to the actuator and the ESP unit. EMB designs also need a backup 12-volt supply or a second power net. In our interviews, OEM buyers said a four-wheel EMB set still costs more than a one-box hydraulic system, and that the gap must shrink before mass-market cars adopt it.

International rules are not finished

China now has GB 21670-2025, but UN R13 and R13-H amendments for electrical transmission braking were still being discussed at UNECE during 2025. Carmakers selling globally may need different validation for different markets. That uncertainty matters most in Europe and North America, where we forecast slower EMB adoption.

Thermal, wear and inspection questions remain open

EMB motors sit at the wheel, exposed to heat, water and road salt. Periodic technical inspection, which today assumes hydraulic lines, needs new test methods; this was one of the topics raised at UNECE in 2025. Workshops also need new tools and training for calibration, which slows aftermarket service.

Growth Drivers

Electric vehicle volume and regenerative braking

Global electric car sales passed 20 million in 2025, about 25% of new car sales, and the IEA expects about 23 million in 2026, or 28% of the global total. In China the share was about 55% in 2025 and is heading toward 60%. An electric vehicle has no engine vacuum to power a conventional booster, and it needs a pedal that is separate from the friction brakes so the motor can recover as much energy as possible before the calipers engage. One-box units such as Bosch IPB and ZF IBC were designed for this job. With OICA recording 96.4 million vehicles produced worldwide in 2025, every extra point of EV share adds roughly a million potential brake-by-wire fitments. We estimate this driver adds about +4.1% to the annual growth rate of the market over the forecast, the largest of the three.

Automated driving needs brakes software can command

Driver assistance and automated driving stacks must apply the brakes without the driver, with fast response and a fail-operational backup. Brake-by-wire gives the vehicle computer direct control of each wheel. This is why Bosch built its by-wire actuator with redundant signal lines, and why BMW chose the Aumovio MK C2 for platforms running into the mid-2030s, in a deal worth more than EUR 1 billion signed in July 2026. Chery pairs EMB with its Flying Fish Chassis 3.0 so that steering, braking and suspension can be coordinated by one controller. As Level 2+ and Level 3 functions spread across mid-size cars, by-wire braking moves from an option to a platform requirement. Radial Insights credits this driver with roughly 2.6 percentage points of the forecast CAGR.

Packaging, weight and assembly savings from dry systems

Removing brake fluid, lines and the vacuum booster frees space in the front of the car, removes a liquid that needs periodic replacement, and shortens assembly steps on the line. Brembo presents Sensify as a fluid-free, software-defined system; Nexteer says its EMB places an actuator at each wheel with no brake fluid. For electric skateboard platforms, the freed space helps with crash structures and battery packaging. ZF says demand for dry systems has risen sharply in Asia, and Chinese suppliers including BWI, Orient-Motion and Jiongyi Electronic were preparing EMB for mass production in 2026. We expect these savings to be worth around 1.5 points of yearly growth, mostly after 2028 as EMB costs fall.

Opportunities

Electric trucks and trailers

Heavy vehicles still rely on air brakes, but electric trucks have high-voltage power and need blended braking. Suppliers that adapt EMB to commercial vehicles, as Haldex has been doing, can open a segment that grows at 16.20% a year in our forecast.

Software, calibration and data services

Brake-by-wire turns pedal feel and braking response into software settings. Suppliers can sell calibration tools, over-the-air updates and brake wear data to OEMs and fleets, which raises revenue per vehicle over its life.

Asia Pacific (APAC) leads brake-by-wire adoption on the back of China's EV market

Asia Pacific (APAC)

Asia Pacific (APAC) held 52.40% of global brake-by-wire revenue in 2025, worth USD 4.53 Billion. Revenue in Asia Pacific (APAC) reaches USD 15.80 Billion by 2035 at a 13.30% CAGR, the fastest of any region. China produced 34.53 million vehicles in 2025 according to OICA, and electric cars were about 55% of its car sales. Chery, BWI, Orient-Motion and Jiongyi Electronic are all pushing EMB to production, and GB 21670-2025 gives Chinese carmakers a clear approval route from 2026. Japan and South Korea add volume through Hitachi Astemo, Advics, HL Mando and Hyundai Mobis.

North America

North America accounted for 18.60% of 2025 revenue, or USD 1.61 Billion. The North America market rises to USD 4.69 Billion by 2035, a 11.30% CAGR. The ZF hybrid design with rear EMB and front hydraulic brakes targets US pickups and heavy light trucks, which make up a large part of North American sales. US vehicle production was 10.24 million units in 2025, down about 3%, according to OICA, which tempers near-term growth.

Europe

Europe generated USD 1.89 Billion in 2025, a 21.80% share of the global total. By 2035 European revenue reaches USD 5.60 Billion, growing at 11.50% a year. BMW's July 2026 MK C2 deal with Aumovio, worth more than EUR 1 billion, keeps one-box systems on German platforms into the mid-2030s, and Brembo's Sensify program gives Europe an early fluid-free reference. The IEA expects about one in three new cars in Europe to be electric in 2026.

Latin America

Latin America represented 3.20% of the market in 2025, equal to USD 0.28 Billion. Latin America grows to USD 0.77 Billion by 2035, a 10.80% CAGR. Brazil and Mexico build vehicles for export to the US, so one-box units arrive first on export programs, while domestic models adopt them more slowly because of cost.

Middle East

The Middle East held 2.40% of 2025 revenue, about USD 0.21 Billion. Middle East revenue reaches USD 0.58 Billion by 2035, growing at 10.90% a year. Demand comes from imported premium SUVs and electric cars, including a growing share of Chinese brands, which already use one-box brake units.

Africa

Africa accounted for 1.60% of 2025 revenue, or USD 0.14 Billion. The African market reaches USD 0.37 Billion in 2035 at a 10.40% CAGR. Assembly plants in South Africa and Morocco build export models for Europe, and these programs bring brake-by-wire into the region well before local retail demand does.

Five global suppliers hold most brake-by-wire revenue, while Chinese specialists race to lead EMB

Competition in the automotive brake-by-wire systems market depends on three things: years of production experience with one-box hydraulic units, readiness of EMB, and the ability to win long platform awards. Global tier-one suppliers hold most current revenue, but Chinese suppliers are moving faster on fully dry systems.

Global one-box leaders

Robert Bosch GmbH sells the iBooster and the Integrated Power Brake, and is starting production of a by-wire brake actuator with redundant signal lines for an Asian carmaker. ZF Friedrichshafen AG has supplied its Integrated Brake Control since 2018 and won a brake-by-wire order for nearly 5 million vehicles in January 2025. Aumovio SE, spun off from Continental, makes the MK C1 and MK C2 one-box brakes and signed a deal worth more than EUR 1 billion with BMW in July 2026. These three suppliers have the largest installed bases and the longest validation records.

Premium and EMB specialists

Brembo N.V., best known for performance calipers, put its fluid-free Sensify platform into series production in May 2026, and reported 2025 revenue of about EUR 3.7 billion. Nexteer Automotive, a steering specialist, launched an EMB system in April 2025 and is pairing it with steer-by-wire. BWI Group, formerly part of Delphi, is developing dual-motor EMB with thyssenkrupp AG and Chinese customers.

Asian tier-one suppliers

Hitachi Astemo, HL Mando Corporation, Hyundai Mobis and Advics Co., Ltd. supply electro-hydraulic and integrated braking units to Japanese and Korean carmakers. They are strong on cost and on close engineering links with Toyota, Honda, Hyundai and Kia. Bethel Automotive Safety Systems supplies Chinese carmakers with electro-hydraulic braking and is a domestic alternative to global suppliers.

Chinese EMB start-ups and commercial vehicle entrants

Orient-Motion Technology and Jiongyi Electronic were preparing EMB for mass production in 2026, helped by GB 21670-2025. Haldex AB is adapting electromechanical braking for commercial vehicles. We expect consolidation as start-ups look for global partners and established suppliers buy EMB capability.
