Bosch tests brake-by-wire system on 3.300 km journey to the Arctic Circle and predicts 5,5 million vehicles equipped by 2030! Technology eliminates hydraulic components, reduces weight and promises faster, safer braking. Bosch's brake-by-wire could be the next big leap in automotive technology
Bosch is set to change the automotive industry’s game with its latest innovation: brake-by-wire. Recently tested on public roads, this system promises to revolutionize the way vehicles brake by completely eliminating the mechanical connection between the pedal and the brakes. But is this technology really ready to take center stage in modern cars? Let’s explore how this innovation works and its potential impacts.
What is the Bosch brake-by-wire system?
Brake-by-wire, or brake by wire, is a concept that replaces the traditional connection hydraulics between the pedal and the brakes by an electronic system. Instead of actuating a master cylinder and pushing fluid to the brake calipers, the driver simply sends an electrical signal to a remote actuator, which then applies the pads against the brake disc.
This eliminates the need for hoses, reservoirs and hydraulic cylinders, resulting in a lighter and more compact system. The technology enables faster and more efficient responses, ensuring precise and reliable braking.

Bosch testing and implementation in the Nissan Ariya
To prove the effectiveness of brake-by-wire, Bosch put the system to an extreme test. A development team drove a Nissan Ariya over 3.300 km to the Arctic Circle, enduring a variety of weather conditions to assess the technology’s performance.
This trip was crucial to verify the system’s resistance and reliability in extreme temperatures and varied terrains. The result? The system demonstrated excellent performance, reinforcing its viability for the automotive market.
Main advantages of the brake-by-wire system
Adoption of Bosch brake-by-wire can bring a number of benefits to both manufacturers and drivers. Among the main advantages, we can highlight:
1. Weight reduction and greater efficiency for electric vehicles
Electric cars rely on lightweight design to increase their range. Because brake-by-wire eliminates heavy hydraulic components, the vehicles can become more efficient and consume less energy.
2. Flexibility in automotive design
By eliminating mechanical connections, automakers have more freedom to position brake actuators in strategic locations. This makes it easier to produce right- or left-hand drive models, as well as opening up space for innovative interior designs.
3. Greater security and electronic redundancy
The Bosch system uses two independent actuators: a by-wire actuator and an ESP (Electronic Stability Program). This redundancy means that, even in the event of a failure, the braking pressure can be adjusted on all wheels, increasing safety.
The challenges and limitations of brake-by-wire
Despite the advantages, the technology still faces some challenges. One of the main ones is the reliability of the electronic system. Since braking depends on electrical signals, failures can compromise safety. To avoid this, Bosch has incorporated redundancies, but public acceptance may still be an obstacle.
The idea of applying brake-by-wire to motorcycles has also been discussed, but it presents complications. Unlike cars, motorcycles need an extremely reliable system, since any failure could be fatal for the rider. Therefore, there is still no forecast for this technology to be adopted on two-wheeled vehicles.
When will this technology hit the market?
Bosch has already received orders from automakers interested in the system and estimates that by 2030, more than 5,5 million vehicles will be equipped with brake-by-wire. The technology is expected to be available for sale later this year. bringing a new standard of efficiency and safety for the automotive industry.
