The Evolution of Automotive Steering Shows Why Electric Technology Is Replacing Hydraulic Systems in Modern Vehicles

The technological evolution of automobiles has transformed various mechanical systems in recent decades. Among these changes, the steering system has undergone one of the most significant transformations in modern automotive engineering. For many years, hydraulic steering dominated vehicles and provided assistance to the driver through pumps and pressurized fluid.

With the advancement of embedded electronics, however, automakers began to adopt electric steering on an increasingly large scale around the world. According to technical analyses from the Society of Automotive Engineers (SAE International) and the National Association of Motor Vehicle Manufacturers (ANFAVEA), this change gained momentum particularly from the 2000s. Since then, manufacturers have invested in more efficient, precise systems with lower maintenance needs, keeping pace with the technological evolution of modern vehicles.

Energy Efficiency Explains the Advancements of Electric Steering

Energy efficiency is one of the main factors driving the adoption of electric steering. In the traditional hydraulic system, the vehicle’s engine continuously drives a pump that maintains fluid pressure. Even when the driver does not turn the steering wheel, the system continues to consume energy.

Greater Precision in Vehicle Control

Another factor that differentiates electric steering from hydraulic steering involves the level of precision in steering control. While the hydraulic system relies on fluid pressure and mechanical components, electric steering uses sensors and electronic modules.

These sensors monitor the movement of the steering wheel and adjust assistance immediately. Thus, the driver experiences smoother and more precise responses during driving. Additionally, electronic systems allow for more refined adjustments that vary according to vehicle speed or driving conditions.

Experts from Bosch Automotive Technology highlight that engineers have been perfecting this type of control since the 1990s, when the first electric steering systems emerged in the automotive industry.

With dimensions of a baseball field, 18 integrated engines, a series hybrid system, and an average consumption of 388 liters of diesel per km, the largest self-propelled vehicle on the planet is responsible for transporting NASA’s SLS rocket to the launch base for Artemis missions that aim to take humanity back to the Moon

Lower Maintenance Requirements

Electric steering also stands out for its lower maintenance requirements. The system has fewer mechanical components subject to natural wear and tear.

In hydraulic steering, the system relies on the circulation of pressurized fluid, requiring periodic checks and fluid replacement. Electric steering eliminates this need, as it does not use hydraulic fluid to assist the steering wheel.

Consequently, the system reduces mechanical complexity and decreases the likelihood of failures related to leaks or component wear. Studies published by SAE International throughout the 2010s indicate that reducing moving parts increases the reliability of electric systems.

Technology Increasingly Present in the Automotive Industry

In recent decades, electric steering has transitioned from an experimental solution to being integrated into many modern vehicles. The advancement of embedded electronics and automotive technologies has driven this transformation.

Moreover, the pursuit of energy efficiency and lower maintenance needs strengthens the preference for electric systems. For this reason, automakers incorporate electric steering into new automotive projects, consolidating this technology as one of the main evolutions of steering systems.

In light of this technological transformation, experts indicate that the replacement of hydraulic steering with electric should continue in the coming years, keeping pace with the evolution of automotive engineering.

In light of this silent change happening within today’s cars, do you believe that electric steering represents the definitive future of automotive driving?

Technology Increasingly Present in the Automotive Industry

With billions in loans, China is rebuilding Nigeria’s railway network from scratch, abandoning the British colonial tracks that have turned to scrap and creating a corridor of over 1,300 km to take the load off the roads of Africa’s largest economy.

Forget petroleum-based asphalt: a Scottish company transforms 684,000 plastic bottles into one kilometer of road that is 60% more resistant and up to 10 times more durable, and the technology has already started replacing traditional asphalt in more than 30 countries.

Austrian engineers have developed an inflatable concrete technology that transforms flat slabs into domes using only air pressure, eliminating scaffolding and temporary forms, and potentially changing the way bridges, tunnels, and curved roofs are constructed worldwide.

China is building an artificial island in the middle of the sea, covering 20 km², to construct the largest offshore airport in the world, the Dalian Jinzhouwan. This $4.3 billion project is anchored on more than 3,000 pillars embedded in the rock beneath the ocean and is scheduled to open in 2035.

A robot named Walter does the work of five bricklayers per hour and can save the construction industry, where the average age of professionals is 46 years and almost no one wants to learn the trade anymore, in the United Kingdom.

Spain installs two giant pipelines 2.2 km off the coast to draw water from the Mediterranean and supply a megafacility capable of producing 200 million liters of drinking water per day.

A 250-ton transformer traveled 1,929 km by road in India on a slow and planned journey that demonstrates how the power grid relies on giant loads, detours, and impossible routes for regular trucks.

African country launched a $145 million project to rehabilitate 35 dams and drill deep wells seeking water stored for millennia beneath the desert, a plan that Captain Ibrahim Traoré’s government presents as a path to the country’s water sovereignty.

A 400-meter colossus powered by natural gas has just set sail from Shanghai to Europe, carrying over 24,000 containers. It is the world’s largest dual-fuel container ship and can cross the planet without refueling even once.

The largest highway concession company in Brazil already belongs to an Italian group, and now the railway sector may be next to receive billions in investments from Italy amid the progress of the Mercosur and European Union agreement.

A new study overturns the central idea we learned about planets and suggests that Earth is the exception rather than the rule; most rocky worlds in the galaxy may not have a core or mantle, just a single turbulent fluid extending to the center.

Almost no ship sails directly between South America and Australia, and the reason is a combination of the vast distance, winds that circle the planet nonstop, and the absence of ports along the way, leaving the South Pacific as a water desert.

Forget the basic popular car: used sedans like Passat CC, Kia Cerato, Nissan Altima, Mitsubishi Lancer, and Volvo S60 show that it’s still possible to buy more performance, comfort, and technology for less than many new compacts.

Used Honda Civic: 3 versions of the Japanese sedan with naturally aspirated engines of up to 155 hp, fuel consumption of up to 13.8 km/l, robust automatic transmission, and a reputation for reliable mechanics still dominate the used car market in Brazil.

Toyota Hilux becomes a ‘cargo truck’: automaker declares a new era for the pickup with greater capacity, reinforced chassis, 2.8 turbodiesel engine, raised suspension, 1,525 kg load capacity, and targets Ford Ranger Super Duty, which tows an impressive 4,500 kg.
