According to recent analysis published by Market Research Future, electric power steering demand is being driven by a relationship that many observers overlook: every advanced driver assistance feature that touches vehicle direction requires a steering system capable of accepting software commands. Lane-keeping assistance, automated emergency steering, park assist, and traffic jam assist all depend on the same underlying capability. That dependency is why electric power steering has moved from optional to mandatory in vehicles sold in regulated markets.
The ADAS Dependency
A hydraulic steering system translates mechanical input from the steering wheel into hydraulic pressure that assists the wheels. It cannot be commanded by software without substantial modification. An electrical system uses an electric motor to provide assistance and can accept commands from a control unit—whether that command originates from the driver turning the wheel or from an algorithm detecting lane departure.
This distinction is not incremental. It determines whether a vehicle can offer lane-keeping at all. When the European Union's General Safety Regulation mandated lane-keeping systems on new vehicles from July 2024, it effectively mandated electric power steering on every vehicle sold in the region.
Regulatory Cascade
The regulatory sequence is instructive. The EU General Safety Regulation Phase 1 requires intelligent speed assistance, lane-keeping, and emergency lane-keeping on new type approvals. Phase 2, effective from 2026, extends mandatory ADAS requirements to additional commercial vehicle categories.
In North America, NHTSA's FMVSS 127 rule mandating automatic emergency braking for light vehicles by September 2029 requires steering systems capable of executing emergency maneuvers in some scenarios.
Each regulatory step expands the population of vehicles requiring electric steering, and each expansion increases demand.
Why Electrification Reinforces the Trend
Electric vehicles cannot use engine-driven hydraulic pumps because they have no engine. Electric power steering is architecturally necessary rather than preferred. As EV production grows—projected to exceed 20 million units annually by 2027 according to BloombergNEF estimates—steering demand grows in lockstep.
The relationship is direct: every additional electric vehicle adds one electric power steering system to the market. And every electric vehicle also tends to carry more ADAS content, because EV buyers are often technology-oriented and EV platforms are designed for automation readiness.
The Value Escalation
Simple electric power steering systems providing basic assist are commodity components. But ADAS-capable systems require additional capability: steering angle sensors accurate to fractions of a degree, torque sensors, motor position feedback, and control units capable of processing inputs from cameras and radars.
Fail-operational automated driving requires redundancy—dual windings, backup power, and secondary communication paths—so that a single failure does not cause loss of steering control.
The consequence is value escalation. A basic electric system is a modest-cost assembly. A redundant, sensor-rich, ADAS-capable system with software integration is a substantially higher-value component. Suppliers capable of delivering the higher tier command better margins and deeper OEM relationships.
Segment and Regional Distribution
Passenger vehicles represent the largest demand segment. Light commercial vehicles follow, with growing fitment as fleet operators adopt ADAS for insurance and liability reasons. Heavy commercial vehicles retain hydraulic systems more frequently, though electric systems are gaining in applications where automated driving features are being piloted.
Asia-Pacific represents the largest production volume, reflecting vehicle assembly concentration in China, Japan, and India. Europe and North America carry higher value per unit due to greater ADAS penetration and stricter regulation.
The Steer-by-Wire Frontier
The next technology step is steer-by-wire, which eliminates the mechanical connection between steering wheel and road wheels entirely. All input is electrical; road feel is simulated rather than transmitted mechanically.
Steer-by-wire offers packaging freedom—no steering column penetrating the firewall—customizable steering feel, and full compatibility with automated driving. It also requires the highest level of redundancy and safety certification, since there is no mechanical fallback.
Adoption remains early, concentrated in premium vehicles and automated driving platforms. But it represents the direction of travel for suppliers seeking differentiation.
Challenges Constraining Demand
Cost remains the primary constraint in price-sensitive markets. In segments where vehicles sell for under USD 12,000, the cost premium of electric over hydraulic steering can be difficult to justify without regulatory compulsion.
Semiconductor supply concentration creates vulnerability. Microcontrollers and power electronics are sourced from a limited number of suppliers, and disruptions ripple through production.
Cybersecurity requirements for software-controlled steering add validation obligations under UNECE Regulation No. 155, requiring manufacturers to implement comprehensive cybersecurity management systems.
Opportunities on the Horizon
Software-defined steering features—adjustable effort, variable ratio, haptic feedback, customizable feel profiles—create post-sale monetization potential through over-the-air updates. Commercial vehicle electrification opens a secondary demand path. Autonomy development creates structural demand for fully software-controllable steering.
Supplier consolidation is likely, as the engineering investment required for redundant, certified, ADAS-capable systems favors scale.
The Road Ahead
The trajectory of electric power steering demand points toward continued expansion driven by regulatory mandates and electrification. Suppliers who invest in redundancy engineering, software capability, and safety certification will be best positioned—because in a market where every ADAS feature requires a capable steering system, advantage comes from being the supplier that enables the features OEMs must offer.
