Power Mirror
A power mirror is an electrically adjustable side-view mirror that allows drivers to change its position using in-cabin controls. In EVs, it enhances convenience, safety, and aerodynamics by integrating with advanced driver-assistance features.
Overview
Power mirrors, also known as electric side mirrors, have become a standard feature in modern vehicles. Unlike manual mirrors that require physical adjustment, power mirrors use electric motors and control switches to adjust the angle, improving visibility and reducing blind spots.
In electric vehicles (EVs), the concept extends further—mirrors are often integrated with heating elements, auto-folding mechanisms, memory settings, and even camera-based digital mirrors. These innovations align with EV design philosophies, where efficiency, safety, and technological sophistication are top priorities.
Some EVs are replacing conventional power mirrors entirely with camera-based mirror systems, reducing drag, improving aerodynamics, and extending driving range.
How Does It Work?
The operation of a power mirror involves a small system of actuators, sensors, and control electronics:
-
Driver Input – A switch or digital interface inside the cabin lets the driver select and adjust the mirror.
-
Electric Actuators – Tiny motors move the mirror glass vertically, horizontally, or diagonally.
-
Advanced Functions – Many EVs incorporate heating coils to prevent fogging, memory modules for preset positions, and auto-fold mechanisms triggered when locking the car.
-
Digital Integration – In high-end EVs, mirrors may include cameras, sensors, and connectivity to ADAS systems, feeding visual data to in-cabin displays.
This integration allows drivers to optimize visibility with minimal distraction, supporting both safety and convenience.

Applications in EV
Power mirrors are widely used across EV segments, offering enhanced functionality beyond traditional vehicles:
-
Driver Safety – EVs with blind-spot monitoring integrate sensors into power mirrors for real-time alerts.
-
Energy Efficiency – Aerodynamically optimized power mirrors help reduce wind resistance, improving range.
-
Luxury & Comfort – Premium EVs like Tesla, Audi e-tron, and Lexus RZ feature power-folding or camera-based digital mirrors.
-
Urban Utility – Compact EVs benefit from foldable mirrors for easy parking in tight city environments.
Conclusion
Power mirrors may seem like a small component, but in electric vehicles, they play a crucial role in driver convenience, safety, and aerodynamic performance. As EVs evolve, traditional power mirrors are transitioning toward smart digital mirror systems, reflecting the industry’s push toward greater efficiency, connectivity, and innovation.
